Coating classification: plastic coating

Core tip: plastic coating is the coating applied on plastic materials In recent years, plastic coating has been widely used in mobile phones, TV sets, computers, automobiles, motorcycle accessories and other fields, such as automobile external parts (bumpers, mirror covers, car side covers, etc.) and internal parts (CAB dashboard, door panels, airbag covers, steering covers, etc.); in addition, plastic coating is also widely used It is widely used in sports and leisure equipment, cosmetics packaging, toys, etc Chinese name plastic coating category coating application scope mobile phone, television, computer rise time 2 Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: plastic paint is a kind of paint applied on plastic materials In recent years, plastic paint has been widely used in mobile phones, televisions, computers, automobiles, motorcycle accessories and other fields, such as automobile external parts (bumpers, mirror covers, side covers, etc.) and internal parts (CAB instruments) In addition, plastic coating is widely used in sports and leisure appliances, cosmetics packaging, toys, etc The application scope of plastic coating is mobile phone, TV set and computer In 1980s, there were many kinds of plastic base materials, with different chemical and physical properties In terms of mechanical properties, they can be divided into hard and soft plastics; in terms of surface properties, they can be divided into polarity and weak polarity Common plastic materials include polystyrene, polymethylmethacrylate, polyvinyl chloride, polyethylene, polypropylene, polyester, polycarbonate, ABS plastic, etc The physical properties of plastics with the same or similar components may be different In addition to the ordinary brittle varieties, polystyrene also includes high impact polystyrene; polyethylene materials include hard high-density polyethylene and soft low-density polyethylene The surface of plastics made of polyester, polymethyl methacrylate, polycarbonate and other materials has certain polarity, and the adhesion problem of UV coating on them is easy to solve; the surface polarity of polyethylene and polypropylene is very low, and the adhesion performance of UV coating is generally poor, so it is often necessary to conduct spark discharge, corrosion and other polarity treatment for plastics, or add adhesion promoter in the formulation of UV coating For example, chlorinated resin can improve the adhesion of polypropylene Due to the different properties of plastic materials, the suitable formulation of UV curing coating will also be different Background most of the plastic original embryo products are extruded or press molded In the process of hot extrusion, trace air or volatile impurities in the raw materials may escape to the surface, forming more micro defects such as "crater", resulting in the reduction of surface gloss and poor aesthetic degree In addition, most of the conventional plastic parts are not wear-resistant, solvent resistant, easy to scratch, fog, surface damage, etc., so it is necessary to decorate and protect the surface of the plastic parts Plastic materials with poor light aging performance can also be protected by UV coating with light stabilization to prevent or delay the aging of plastic substrate, which is particularly important for outdoor use and long-term exposure to sunlight and artificial short wave light source (such as fluorescent lamp) According to statistics, from 1994 to 2004, the demand for automotive plastics in China increased by 27.8%, and the output reached 220000 tons in 2004 With the continuous expansion of domestic automobile production capacity, the consumption of automotive plastics is expected to reach 500000 tons in 2009, with an average annual growth rate of 18% As the domestic output is difficult to meet the demand, China will import automotive plastics in the future In 2004, the import volume of automotive plastics in China was 480000 tons, and it is expected to reach 950000 tons in 2009 The consumption of automotive plastics has reached 20-25% of the total vehicle quality From a single variety of market, in the future, the automotive parts application field is the largest market of plastic coatings, accounting for about 42% of the total plastic coatings market The increase of plastic coating for building has become a trend of development in the future PVC protective coating will be a development direction, and the demand for fire retardant coating for plastic products will continue to grow The growth of a large number of demand for personalized and decorative products in the family also further expands the demand field of plastic coating UV plastic coatings are increasing year by year UV plastic coatings are mainly used in mobile phones, computers, cameras, household appliances, cosmetics packaging and other fields In Asia, the demand for plastic coatings in these applications has reached 18000 tons per year, with an increase rate of 15-20% per year China is the second largest application market in Asia, but due to the relatively small number of manufacturers specializing in the production of plastic coatings, imported products still dominate In 2006, the production of UV plastic coatings in China exceeded 6000 tons, and it is expected to exceed 7000 tons in 2008 At present, the domestic plastic coatings are mainly solvent based coatings, which have heavy pollution and large energy consumption In the future, they will also develop towards the direction of water-based, radiation curing and solventless like other coatings The current market situation of plastic coatings in China started in the early 1980s With the rapid development of plastic products industry, the development trend of plastic coatings is rapid, especially in the automotive industry, household appliances and other fields In 2007, China's demand for plastic products reached 35 million tons, and the consumption of plastic coatings exceeded 120000 tons, with an average annual growth rate of 10% - 15% The consumption of plastic coatings in our country is in the forefront of the coating industry, which only ranks behind architectural coatings, automotive coatings, anticorrosive coatings and wood coatings, with a promising market prospect China's plastic coatings have developed rapidly from general decoration to special function, from solvent type to water type, and have developed and produced plastic coatings that can be used for coating ABS, hips, PS and PP substrates, with the application fields continuously expanding The main varieties are: thermoplastic acrylate resin coating, thermosetting acrylate polyurethane resin modified coating, chlorinated polyolefin modified coating, modified polyurethane coating and other varieties, of which acrylic coating is the most widely used Due to the application of plastic coatings are mostly high-tech and high value-added products, many high-tech coating products in the coating industry are also continuously applied in plastic coatings, such as angle based heterochromatic coating, pearlescent coating, ceramic coating, intelligent coating, special functional coating, etc The requirements of these application markets for plastic coatings and the quality of the plastics used determine the development direction of plastic coatings For example, plastic coatings for mobile phones are required to have metal color, high hardness and anti electromagnetic radiation; plastic parts for automobiles are required to have high touch sensitivity; plastic coatings for toys should be non-toxic, novel in appearance, full of the flavor of the times, etc the high-end market of plastic coatings in China is now controlled by foreign large companies, mainly Akzo Nobel of the Netherlands, DuPont company and PPG company, Japan's Musashi coating company, etc Akzo Nobel's new factory in Tianjin Development Zone and its factories in Dongguan, Guangdong and Jiashan, Zhejiang mainly produce wood and coiled materials In September 2007, PPG industry group of the United States invested 10 million US dollars to set up a new factory in Tianjin for the production of consumer electronic products coatings and industrial coatings, with a production capacity of 70000 tons Japan Musashi coating company invested in the commercial production of plastic coatings in Tianjin plant, and its products mainly include Coating for mobile phone surface, electronic instruments and home appliances, etc Most of the domestic enterprises mainly produce middle and low grade plastic coating products The factories are mainly in Guangdong, Zhejiang and Jiangsu Market share In the world, the application fields of plastic coatings are different; in Europe, the market share of plastic coatings for auto parts (including modified PP and RMP) accounts for about 50%, while in China, the market share of plastic coatings is about 20.2% for automobiles, 29% for mobile phones, 18.6% for computers and related products, 10.9% for toys, 9.2% for household appliances and 12.1% for other products (including footwear) In China, the market price of plastic coating is different The price of plastic coating products is also significantly different in different application fields, and the price of imported brands is also quite different from that of domestic brands Auto parts: for interior and external plastic parts, such as bumper paint, the price of foreign brands is 60 yuan per kilogram, and that of domestic brands is 45-50 yuan per kilogram Household appliances: due to the import of raw materials and other factors, the price difference is large The price of foreign brands is 90-130 yuan per kilogram, and that of domestic brands is 55-60 yuan per kilogram Mobile phones and computers: mainly UV plastic coatings Due to unique process operation factors, the
