Carbon dioxide synthesis of biodegradable plastic development progress in China
Since the 1990 s, guangzhou chemistry, zhejiang university of Chinese Academy of Sciences, lanzhou university, Chinese Academy of Sciences changchun should have successively carried out carbon dioxide fixation for the research of biodegradable plastics, and achieved gratifying progress. Cas guangzhou chemical company to complete the copolymerization of carbon dioxide and use carbon dioxide efficient synthesis of biodegradable plastic research, pilot test results of this project has been transferred to guangzhou guangzhong enterprise group co. , LTD. , joint carbon dioxide degradable plastic 5000 tons/year industrial test. The project in terms of catalyst, innovative was prepared with independent intellectual property rights of a variety of load carrying carboxylic acid zinc catalyst. The catalytic systems of low cost, the use of safe, simple preparation, suitable for industrial scale production application. In 2001, the Chinese Academy of Sciences changchun should be fixed to carbon dioxide and use the industrialization of research and development work, cooperate with stake high-tech group company, after three years research, built the world's first 3000 tons/year 'carbon dioxide based fully degradable plastic masterbatch industry demonstration line. Domestic first set of carbon dioxide degradable plastic industrial production device by stake in Inner Mongolia hi-tech group built in early 2004. The project designed by the light industry design institute of Inner Mongolia, the use of the Chinese Academy of Sciences changchun institute of applied chemistry technology, the production scale of 3000 tons/year. Is said to have its products could be partly replacing polyvinylidene fluoride, polyvinyl chloride, such as medical and food packaging materials, and can be used in the disposable food and drug packaging. According to the technical data provided by the stake group, is now mass production of carbon dioxide based plastic masterbatch are mainly carbon/epoxy propane, carbon dioxide copolymer/epoxy propane/epoxy ethane terpolymer, carbon/epoxy propane/epoxy cyclohexane terpolymer three varieties. Under the condition of mandatory compost, 5 ~ 60 days can be completely decomposed.
