Diacetone acrylamide is an important class of fine chemical products, widely used in coatings, adhesives, hair spray, epoxy curing agent, photosensitive resin additives, textile auxiliaries, paper enhancers, medical and health fields. It is used in the emulsion with adipic acid dihydrazide, which can greatly improve the antifouling performance and the film forming performance, so that the paint film has strong adhesion, good stability, is not easy to produce cracks, and the film is glossy. It can be used as a plasticizer to produce hair gel and high-efficiency cold-scalding essence, and it is currently used in a large amount in the Japanese hair spray market.
Diacetone acrylamide can also be used to produce breathable and breathable films, contact lenses and glass anti-fogging agents, etc. The highly effective, special epoxy curing agent produced by reacting with amines has low toxicity, UV stability and Good weather resistance, chemical resistance, small cure shrinkage and crack resistance. Due to the photocrosslinking property of the diamine homopolymer itself, the photosensitive resin produced with diacetone acrylamide as an additive has the advantages of rapid photosensitivity, clear image, high mechanical strength of layout, and favorable thin layer coating, and is suitable for high temperature in our country. Obvious technical requirements.
At present, the major manufacturers of diacetone acrylamide in foreign countries include the United States Lubricating Oil Company, Japan Union Oil Corporation, the Dutch National Mining Company, and the German BASF Company. The annual production volume is about 10,000 tons. In foreign countries, diamines have also been copolymerized with acrylamide, acrylic acid and vinyl-2-methylimidazole to obtain a good alternative to gelatin. The molecular structure of diacetone acrylamide is similar to that of gelatin. It is used as a partial substitute for gelatin. It has strong protection and peptizing ability for silver halide, good miscibility, and can increase the hiding power of silver salt, so as to achieve the purpose of saving silver. The long-term supply of gelatin in our country does not require, therefore, the development of diacetone acrylamide as a substitute for gelatin is of great significance.
Hangzhou Xinghua Successfully Developed Diacetone Acrylamide
Hangzhou Xinghua Fine Chemical Co., Ltd. has successfully developed diacetone acrylamide, which has changed China's reliance on imported products. The company is currently working on the development of its downstream products, both interior and exterior latex paints and waterborne wood coatings.
