According to data released by the National Statistics Department, the total output of the paint industry in China reached 2,981,500 tons in 2004, which has become the largest producer of paint in the world after the United States. However, from a technical perspective, China is still not a strong painter, and paint production technology and equipment lag behind industrial advanced countries for 20 years. Over the years, the Chinese coating industry has strived to realize its dream of becoming a strong nation and has embarked on the road to independent innovation, and has achieved fruitful results.
Automotive coatings Electrophoretic coatings for automotive use in China started in the mid-1960s. From anodic electrophoretic coatings to cathodic electrophoretic coatings, they were basically synchronized with foreign countries. China National Chemical Construction Changzhou Institute of Coatings and Chemicals undertook the national key scientific and technological research project - automotive water paint new product project, based on the coating of auto bodywork and high performance automotive, especially car parts, to develop a new generation of high performance Cathodic electrophoretic coatings were certified by the Ministry of Science and Technology in 2000 and obtained two national invention patents. The HED-3000 high-performance cathodic electrodeposition coating developed on the basis of this project has been widely used in the domestic high-end auto parts field. China's automotive refinish paint (including color grading and color matching technology) has become increasingly mature. Changzhou Automover Automotive Coatings Co., Ltd. has independently developed three generations of products, with up to 1,000 color formulations, which can meet most of the market's refinish paint colors. demand.
Anti-corrosion coatings Anti-corrosion protection coatings mainly include marine coatings, container coatings and industrial anti-corrosion coatings. There are a wide variety of marine coatings, and our country can basically develop it. China's fishery coatings have basically adopted the products of domestic enterprises such as Shanghai Kailin, Qingdao Haijian and Zhuhua Guangqi. After more than 20 years of hard work, China's anti-corrosion coatings have changed the situation of relying solely on imports. With the current advanced level of spraying polyurea elastomer anti-corrosion coating, polyaniline anti-static anti-corrosion coating, super weather-resistant fluororesin powder coating and water-based anti-corrosion coating has the scale of production technology and capabilities.
Architectural Coatings The production technology and varieties of architectural coatings in China have reached the international level in the early 1990s and can basically meet the demands of the construction and decoration industries. At the beginning of the 21st century, China introduced the Japanese FEVE technology. The FEVE resins based on trifluoroethylene and tetrafluoroethylene, respectively, have developed rapidly in China and formed a "fake-wall external wall fluorocarbon coating technology" with Chinese characteristics. Not long ago, Beijing University of Chemical Technology, Shanghai Huasheng Chemical Co., Ltd., and Beijing Xinte Technology Development Co., Ltd. jointly solved the entire set of engineering-friendly technologies and equipment for environmental friendly polyurethane curing agent products with proprietary intellectual property rights. Such curing agent products can only rely on the era of imports.
Coil coating China's early 1980s, the former Ministry of Chemical Industry and the Ministry of Metallurgy on the joint organization of coil coating research and development, so that China has gradually formed a coil coating industry. At present, research institutes in the chemical and metallurgical industries are cooperating in the research and development of technologies with independent intellectual property rights in coating materials. At present, there are more than 150 domestic coil production lines and more than 2 million tons of color-coated steel sheets and color-coated aluminum sheets, of which the construction industry accounts for more than 80% of consumption. The household appliance industry has begun to use and the usage has increased year by year. The flying tiger coil coating material developed and produced by the Shanghai Zhenhua Paint Factory, which is owned by the state-owned largest state-owned coating company Shanghai Paint Co., Ltd., broke the situation where Baosteel’s foreign brands monopolized new products.
Wood Coatings China's wood coatings have entered a period of rapid development since the 1990s, and the output of various wood coatings has reached more than 500,000 tons. The Pearl River Delta region has concentrated 1/3 of the country's wood coating production. At present, waterborne acrylic emulsion coatings and waterborne polyurethane coatings have become hot spots for research and development, and the emergence of UV-cured wood coatings has become the direction of future development of wood coatings. In the hometown of wood coating in Shunde, Guangdong, some powerful coating companies such as China Resources Coatings Co., Ltd. and Guangdong Meitu Chemicals Group have established enterprise technology centers with strong R&D capabilities.
Zhang Junzhi, director of the National Coatings Engineering Technology Research Center and director of the Changzhou Coatings Chemical Research Institute, said that establishing and improving the independent innovation system for coatings in China is the only way for China to move from a big painter to a strong painter. He suggested that the National Coating Technology Engineering Research Center should be the leader to establish a China-selected coating technology innovation system.
