     A barrel of high-end heavy anti-corrosion coatings that are resistant to marine heavy corrosion requires good process lines and collaboration in all aspects, from raw material formulation to large-scale production. When a change occurs in an industrial chain, it can lead to a chain reaction in the whole industry. When AkzoNobel, Xuanwei, Kansi coatings, these international paint giants announced the beginning of a comprehensive price increase of coating products, China's import costs in the field of heavy anti-corrosion coatings gradually increased . There are signs that this global paint price increase, triggered by rising raw material prices, has continued and has not weakened since 2018. Why is China so dependent on imports in the field of heavy anti-corrosion, and where is the way out for domestic brands?
    According to statistics from the National Bureau of Statistics, 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, with total output expected to grow to about 22 million tons. At present, China's defense rotting paint market size has been second only to architectural coatings. Although China has such a large market economy, but it is difficult to hide the domestic paint market by foreign giants monopoly of the embarrassing situation. It is understood that foreign paint giants occupy more than 80% of China's paint market share, to ships and marine engineering heavy anti-corrosion coating, for example, AkzoNobel, PPG, Haihong old man, Jotun, Japan Zhong Tu, Kansi, Japan and other foreign enterprises have divided more than 80% of the market share. It can be said that foreign enterprises in the ship paint, container coatings, marine equipment and marine port equipment in the heavy anti-corrosion paint market, set up a fundamentally does not belong to China's Chinese shopping malls.
    the emergence of new graphene materials is expected to reverse this situation. Graphene, as a new type of nanomaterial, has good corrosion resistance, conductivity and high strength, ultra-thin, oversized surface area and other characteristics. These powerful physical properties can improve the anti-corrosion effect of anti-corrosion coatings, reduce the production costs of anti-corrosion coatings, and promote graphene to become an important raw material driving technological innovation in the coatings industry. After professional testing by a number of coating authorities, graphene can extend the corrosion occurring time and the invasion path of the erosion material, improve the adhesion of the coating and coating protection film quality, in the flexibility test, impact test and the most important corrosion resistance test have shown excellent characteristics, graphene is undoubtedly the most ideal material to be applied to the heavy anti-corrosion coating. The successful application of graphene in heavy anti-corrosion coatings will greatly reduce the economic losses caused by corrosion.
    but over the years, the important issue of graphene heavy anti-corrosion coatings has not been solved. But the fire of hope is being lit, and the key core technologies of graphene anticorrosive coatings are being broken one by one. Domestic graphene anti-corrosion coatings have gradually matured, related technology research and practical applications continue to land, graphene anti-corrosion coatings continue to enter the community and the vision of major enterprises. Under the severe test of the domestic market, domestic graphene enterprises and domestic paint manufacturers launched tacit understanding of technology research and development and supporting production activities.
    in the first half of this year, Zhuhai Polycarbon Composites Co., Ltd., a leading company in the graphene application industry, and Jiangmen Jiabao Chemical Group Co., Ltd., one of the largest providers of coatings and coating solutions, reached a cooperation on the graphene anti-corrosion primer project. I believe that in the future, China's heavy anti-corrosion field can catch up, take back the market share belonging to China's heavy anti-corrosion enterprises, in the international market can compete with other high-end brands. Graphene application giant breakthrough cathode protection technology problems According to the Global Graphene Strategic Research Institute forecast that in 2018 China's graphene anti-corrosion coatings market will reach 500 million yuan, in 2020 China's graphene heavy anti-corrosion coatings in industrial anti-corrosion coating penetration rate will exceed 1%, to 3 billion. By 2022, China's graphene anti-corrosion coatings market will reach 4.8 billion yuan, graphene heavy anti-corrosion coatings are expected to help domestic heavy anti-corrosion coatings to the international high-end market.
    In order to solve the key technical problems in graphene heavy anti-corrosion coating applications, Zhuhai polycarbon by virtue of many years of deep cultivation of graphene research, as well as a number of graphene patented technology, through continuous technological breakthroughs and thousands of experimental research and development, the introduction of graphene oil and water-based series of heavy anti-corrosion coatings, focusing on breaking through the technical problems of graphene for the protection of the metal surface of the cathode, creative solution to the heavy corrosion coating in the ocean complex corrosion environment short life, resistance to the core problem. Chen Xiaogang, Chairman of Polycarbon Composites Co., Ltd., pointed out: "Compared with traditional heavy anti-corrosion coatings, graphene heavy anti-corrosion coatings, in addition to the anti-corrosion effect has been significantly improved, in environmental protection and low-cost mass production also has the advantages of traditional anti-corrosion coatings can not be compared."
    heavy anti-corrosion coatings produced by polycarbons have exceeded the salt spray limit of 800-1000 hours of traditional epoxy-rich zinc under the test standards of GB/T1771-2007 and GB/T 1766-2008. Salt mist time reached 3600 hours (according to test data, the use of graphene anti-corrosion primer, medium paint and finishes made of composite coating salt spray resistance time can exceed 9000 hours), and the key process formulations have independent intellectual property rights, master the core technology at the same time, to achieve a low-cost stability of graphene heavy anti-corrosion coatings. The introduction of graphene heavy anti-corrosion coatings has attracted a lot of attention in the society, including the petrochemical industry giants, PetroChina, Sinopec and CNOOC. In in-depth communication and negotiation with these petrochemical industry giants, HNOOC determined to test the application of polycarbon research and development of graphene anti-corrosion coating, 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, chairman of
    Polycarbon, said: "As a member of the graphene industry, we are eager for graphene technology to be applied to marine corrosion, and we hope that through the graphene heavy anti-corrosion technology, we hope to protect the safe service of the country's major marine infrastructure, to recover the country's economic losses in corrosion." This time with HNOOC smooth cooperation, means that graphene new anti-corrosion coating anti-corrosion effect has been recognized, polycarbon has the ability to rewrite the existing heavy anti-corrosion coating market, in the future anti-corrosion coating layout, we will be more confident to meet the challenge."
    With the "Belt and Road" and the development of the international strategic layout of maritime powers continue to advance, China's development of strategic center of gravity further tilted towards the sea, national strategic interests to the sea direction of rapid expansion, the direction of the sea is facing complex and profound changes in the strategic situation, marine equipment corrosion prevention is also facing new challenges, graphene heavy anti-corrosion technology for the national economic construction and the development of blue industry will be more and more strategic significance. In the future, more green anti-corrosion coatings will be developed, the technology will continue to update and break through. In order to promote the development of marine blue industry, Chinese enterprises should continue to explore and innovate, so that the pace of innovation to keep pace with development, in the protection of marine engineering, marine resources at the same time, do not forget to protect this beautiful sea.
