Complement the domestic high-end anti-corrosion market short board, polycarbonate issued two graphene heavy anti-corrosion coatings

China is a large maritime country with a coastline of 18,000 kilometers, an area of about 3 million square kilometers, abundant marine resources and a thriving blue economy. According to the 2017 China Oceanic Economic Statistics Bulletin released by the State Oceanic Administration, the country's total marine production in 2017 was 776.1 billion yuan, accounting for 9.4% of GDP.
since China's accession to the World Trade Organization, the proportion of China's foreign trade in national economic activities has steadily increased to the extent that it affects about 60%-70% of China's economy, and it can even be said that without trade, China's economy will not be able to sustain . Therefore, it is of great significance to improve the comprehensive competitiveness of marine industry, explore new ways of marine resource protection and development and new model of marine integrated management, and build a modern marine economic system.
Blue economic new engine" suffering from corrosion is imminent
with the continuous development of China's marine economy, especially China's marine development and the landing of national strategic projects such as the Belt and Road, offshore oil and gas platforms, submarine pipelines, offshore wind power, ship transport, cross-sea bridges, marine transportation facilities continue to increase, coastal seaport terminals, coastal power plants and other facilities are blooming every place. However, while vigorously advocating the construction of resource-saving and environment-friendly society in China, the rapid development of marine economy still has the challenge of resource depletion and corrosion.
estimates, about 20% of the world's metal materials due to corrosion can not be recovered, so the corrosion and protection of metals has attracted the world's attention. Data show that the world's annual economic losses due to corrosion as high as 1 trillion U.S. dollars, about earthquakes, floods, hurricanes and other natural disasters formed economic losses of 6 times the sum. China's annual economic losses due to corrosion amounted to 1.2 trillion yuan, about 441 bird's nests, 7 Three Gorges Project, 46 Qinghai-Tibet Railway. The losses caused by corrosion continue to plague industries around the world, particularly in the oceans.
Anti-corrosion market demand is increasing market volume will exceed trillion
At present, corrosion problems are mainly through anti-corrosion coating of engineering equipment to solve, as a corrosion-resistant "bulletproof", anti-corrosion coating market demand is growing. In China, especially in the anti-corrosion specifications have strict requirements of petrochemical, pipeline transportation, marine engineering and other industries, the demand for anti-corrosion materials and heavy anti-corrosion coatings has always maintained a sustained and stable growth trend.
during the 13th Five-Year Plan period, the average annual growth bottom line of China's paint industry is about 6.5%, and by 2020, the total output value of China's paint industry is expected to grow to about 560 billion yuan, and the total output value is expected to grow to about 22 million tons.
, heavy anti-corrosion coatings as a relatively harsh corrosion environment, but also can achieve a longer protection period than conventional anti-corrosion coatings, is widely used in engineering equipment and facilities with harsh corrosion conditions. With the exploration and development of deep-sea resources and the implementation of the strategic goal of "going to deep-sea ocean", heavy anti-corrosion coatings will have a broader market volume.
analysis of recent data, we found that between 2010 and 2017, China's heavy anti-corrosion coatings market sales revenue fluctuated and increased, the growth rate is roughly similar to the total industrial output value. In 2017, the heavy anti-corrosion coatings industry achieved sales revenue of 88.465 billion yuan, up 14.0% YoY.
according to the forward-looking industry research institute", "2018-2023 China's heavy anti-corrosion coating industry development prospects forecast and leading enterprise business analysis report" forecast analysis, by 2023 the heavy anti-corrosion coating industry will achieve sales revenue of 198.1 billion yuan.
high-end anti-corrosion coatings difficult to find domestic brands market volume difficult to mask the technology gap
China has hundreds of billions of levels of anti-corrosion coatings market, but the domestic anti-corrosion market pattern is a different picture. Taking the ship heavy anti-corrosion coatings market as an example, AkzoNobel, PPG, Haihong Old Man, Jotun, Japan Zhong Tu, Kansi, Japan and other foreign enterprises basically divided 80% of the market share. In 2017, Haihong Old Man, Japan Zhong Tu, Kansi, Japan and Korea KCC in the container heavy anti-corrosion coatings market share even reached a staggering 95%, foreign giant paint enterprises have basically formed a relative monopoly of the domestic market competition pattern. Even if the heavy anti-corrosion coatings market is growing at a high rate every year, to the growth of domestic enterprises brought a certain opportunity, but limited to the gap in technology, domestic anti-corrosion brands obviously lack market competitiveness.
as a developing country, China's economic and technological development has made great progress, but that does not mean that all technologies can compete with the international chamber, at least not in the high-end area of heavy anti-corrosion. For historical reasons, the research and development of China's national defense rotting paint started late, coupled with the international community's long-term blockade of Chinese technology, China's national defense rotting paint technology grew up to throw a lot of way to go.
it is understood that in the global heavy anti-corrosion industry chain, from raw material formulation to technology research and development and many other chain links, Chinese paint enterprises can only rank in the middle and low end of the first echelon. There is no independent intellectual property technology, lack of corresponding technical standards, production equipment iteration lag and other issues, for the long-term development of China's blue industry is very unfavorable.
, some of the domestic large-scale, key projects, but where the need for high-specification anti-corrosion treatment technology, you can see the presence of foreign brands. For example, in the world's largest coal chemical project, Flour, built in China, heavy anti-corrosion coatings are earmarked by companies such as AkzoNobel and Jotun. China's largest building - Shanghai Central Building related anti-corrosion fire paint is basically also used AkzoNobel paint, the above examples, numerous. Long-term foreign paint giants grasp this key resource, like the throat is choked at any time, once there is a problem, only corrosion of a loss is incalculable.
Well-deserved king of new materials graphene to promote heavy anti-corrosion industry new bureau
graphene as a new type of nanomaterials, has a "new material king" reputation, its good barrier performance and shielding performance, as well as with excellent conductivity, thermal conductivity, ultra-thin, oversized surface area and other characteristics, so that it becomes a natural functional material to improve the performance of anti-corrosion coatings, reduce the cost of anti-corrosion coatings.
After many authoritative experimental data show that graphene as a key material in the anti-corrosion coating plays a particularly obvious role, it can effectively block the external environment, corrosive substances and other penetration and diffusion to the metal substrate, and form a dense protective layer, with good anti-corrosion effect, low coating thickness, high adhesion, light weight, good mechanical performance, salt spray resistance, long life and low cost advantages, is a good upgrade of traditional anti-corrosion coating products. Once graphene is successfully applied in anti-corrosion coatings, it will greatly improve the negative impact of corrosion loss on economic development, and will also become a new bright spot and new driving point of industrial anti-corrosion coatings.
in the recently released "2018 Graphene Technology Patent Analysis Report" shows that the world's total number of graphene-related technology patents, China filed the largest number of patents, reaching 37,521, ranking first in the world, accounting for 66.5% of the share. Policy support, technology-driven, capital entry, China's scientific and technological innovation "bend over-bus" has brought new opportunities, but also for China's industrial anti-corrosion paint reform ushered in a new opportunity for change.
It is understood that the domestic graphene anti-corrosion coatings have become mature, related technology research, landing application products with the expansion of market demand, coating enterprises to promote, graphene anti-corrosion coatings are gradually recognized by the relevant enterprises. It is worth mentioning that in the "foreign enemy" pressure situation, graphene enterprises and paint manufacturers have tacitly launched research and development technology and production technology in-depth cooperation.
in the first half of this year, Zhuhai Polycarbon Composites Co., Ltd., which has extensive research and development experience in graphene, and Jiangmen Jiabao Chemical Group Co., Ltd., one of the largest providers of coatings and coating solutions in China, launched cooperation in the field of graphene epoxy anticorrosive primers. Believe that in the future, in the high-end anti-corrosion coatings market, China's defense anti-corrosion coatings brand can not only rise to the fore, even on international platforms can also compete with international brands.
Graphene anti-corrosion coating advantages obvious economic and environmental effects outstanding
According to Zhuhai Polycarbon Composites Co., Ltd. Chairman Mr. Chen Xiaogang introduced, "compared to the traditional heavy anti-corrosion coatings, graphene anti-corrosion coatings in addition to the performance has been greatly improved, but also has the traditional anti-corrosion coatings can not be compared with environmental protection and cost advantages." "It is well known that corrosion is caused by contact with air, water or other corrosive media on metal surfaces, and the main way to address corrosion is to coat the metal for corrosion protection through physical isolation, chemical, and electrochemical reactions. At present, in the field of heavy corrosion of steel structure, zinc-rich coatings are widely used worldwide to treat corrosion, because the electrode potence of zinc is lower than that of steel, by sacrificing the role of anodes to make steel less likely to be corroded, but the use of a large number of zinc powders will not only increase the cost of coating, but also bring serious "zinc pollution".
Graphene material's own properties make it a natural advantage in physical and electrochemical corrosion protection, graphene sheet layer structure layer by layer, staggered arrangement, in the coating can form a "maze-type" shielding structure, can effectively inhibit the immersion, penetration and diffusion of corrosive media, improve The physical barrier of the coating, at the same time, graphene conjugate structure makes it have a high electron migration rate, showing good conductivity, its layer structure can also ensure better electrochemical contact between coatings, forming a strong conductive network, and thus can use less zinc powder to achieve the same cathode protection.
And in the formulation of graphene anti-corrosion coating, mainly refers to the anti-corrosion principle is the shielding action-based powder, can be replaced with graphene, and graphene addition is only 0.5%-2%, can replace 30%-60% anti-corrosion rust filler, its cost reduction, improve the significance of the environment, can be seen.
days, land, people and polycarbon into the graphene anti-corrosion "fast lane
According to CGIA Research forecast, by the end of 2018, China's graphene anti-corrosion coatings market will reach 500 million yuan, 20 In 20 years, China's graphene anti-corrosion coatings in the industrial anti-corrosion coating penetration rate will exceed 1%, will reach 3 billion yuan, 2022 will reach 4.8 billion yuan, graphene anti-corrosion coatings are expected to help domestic anti-corrosion coatings into the international high-end market.
since the birth of graphene in 2004, in just over a decade, graphene has developed into a super-large industry with more than one trillion volumes. In China, graphene has even risen to the national strategic level industry, policies and industrial funds support unprecedentedly large, governments at all levels have also introduced corresponding supporting policies and measures, a variety of graphene industry alliances, research institutes, innovation centers, enterprises springing up.
As early as last year, Zhuhai Polycarbon Composites Co., Ltd. has successfully realized the commercial operation of graphene anti-corrosion coatings, polycarbon relies on its unique physical graphene production patented technology, through continuous accumulation of experience and practical applications, the successful development of graphene oil and water-based anti-corrosion series of coatings. According to the inspection report issued by the Aging Quality Supervision and Inspection Center of synthetic materials in the chemical industry, graphene heavy anti-corrosion coatings produced by Zhuhai Polycarbon Composites Co., Ltd. are 1766 in GB/T1771-2007 and GB/T 1766 Under the 2008 standard, the aging time of salt spray resistance can reach 3600 hours, while the time of salt spray resistance with a composite coating consisting of graphene anti-corrosion primer, medium paint and finish paint exceeds 9000 hours. Break through the traditional epoxy zinc-rich coating 800-1000 hours of salt spray resistance limit, one step to achieve domestic heavy anti-corrosion paint products to the process of high-end.
through previous reports, we found that Zhuhai Polycarbon Composites Co., Ltd. not only in the field of graphene corrosion prevention, in the new carbon materials, mechanical lubrication, electric heating, power energy and other fields also occupy an important technical position. It is understood that polycarbon has a number of graphene production and preparation process patented technology, but also the world's few can be accepted by the industry to achieve large-scale production and truly achieve "zero emissions" graphene production and application research and development enterprises.
At the time, the emergence of graphene anti-corrosion coatings, in a short period of time it is difficult to improve the long-term defense corrosion industry by foreign enterprises, the rise of anti-corrosion coatings industry, can not be separated from graphene technology, paint manufacturers, policy-oriented and application-side support, in general, graphene anti-corrosion coatings ahead of the bright road, but the road is still tortuous. In the industry, more enterprises such as polycarbon are needed to promote the development of graphene heavy anti-corrosion coatings in all aspects of technology development, environmental performance assessment, standard-setting, engineering application and industrialization.
In the course of the actual visit, we found that the product end application of graphene anti-corrosion coatings is not as popular as advertised on the Internet, but Zhuhai Polycarbon Composites Co., Ltd. Chairman Mr. Chen Xiaogang revealed to us that polycarbon compound has been with "China's three barrels of oil", PetroChina, Sinopec, CNOOC three leading petrochemical industry enterprises have been in close contact. Among them, in contact with HNOOC, has reached a preliminary coating test cooperation, graphene anti-corrosion coating will be the first in which HNOOC Zhuhai Natural Gas Power Co., Ltd. large-scale steel structure coating applications. Chen Xiaogang said: "This successful completion of cooperation with CNOOC, means that domestic anti-corrosion coatings have finally been affirmed by state-owned enterprises, confirmed that polycarbon graphene anti-corrosion coating performance is indeed better than traditional anti-corrosion coatings, in the next anti-corrosion coating layout, we will be more confident to meet new challenges."
the emergence of domestic graphene new heavy anti-corrosion coatings like a timely rain, not only to improve the anti-corrosion quality of domestic anti-corrosion coating products, but also to fill the domestic high-end anti-corrosion brand market gaps. This is of great strategic significance for ensuring the safe service of marine equipment, marine engineering and major national infrastructure, promoting the industrial upgrading of anticorrosion coatings, impacting the monopoly position of international brands in the domestic market, enhancing the competitiveness of China's blue economic industry construction, and safeguarding national security and marine economic development strategy.
