Recently, the reporter learned from the Science and Technology Bureau of Jiangyin City, Jiangsu Province that China's scientific research team has successfully developed a gloss-adjustable water-soluble acrylic resin through the research on formula and process technology in the past 10 years. Xing Paint) to achieve mass production. Relevant research results have filled the domestic gap and can replace similar imported products. In the future, it will be used in special high-end coating fields such as ships, automobiles, electromechanics, home appliances, and aluminum profiles in my country.
The reporter learned that resin is an essential component of paint. At present, the matting coatings on the domestic market mainly use matting powder, matting paste (matte paste) and other materials to achieve a certain matting performance, but due to the relatively large amount of these fillers, the leveling and mechanical properties of the coating are greatly reduced, resulting in The extinction efficiency is low, the stability is poor, and the gloss cannot be reduced very low. Therefore, domestic related production enterprises have been relying on imported products for powder coatings and other oil-based coatings.
Experts introduced that the research project was undertaken by Wuxi Waterborne Anticorrosive New Material Engineering Technology Research Center, and was listed as a prospective industrialization project supported by Jiangyin City. Over the past 10 years, the scientific research team experts in relevant research institutes in the United Nations have focused on formulas, process technology and other aspects. After repeated trials, through the selection of various raw materials, the optimal design of the formula and the selection of the best process conditions, the resin A matting effect is obtained by the method, and a hydrophilic group is introduced into the molecule of the polymer compound to obtain a water-soluble resin, and a salt-forming method is used to prepare a water-based resin by neutralizing the polymer with carboxyl groups and amines.
Lin Qianlong, chairman of Hengxing Coatings, said that the research results also solved the deterioration caused by chemical reactions such as degradation or re-crosslinking of the polymer chain under the action of heat, light, oxygen, acid and alkali and other chemical media. Solve the problem that the paint film coating is easy to be washed and corroded during use. At present, 9 patents have been applied for.
According to reports, the research results have been rapidly transformed in Hengxing Coatings. The first phase has reached an annual production capacity of 30,000 tons, and is expected to achieve an annual output value of 50 million yuan.
