In recent years, the governments and related enterprises of the positive efforts of biological macromolecule material, great progress has been made to commercialize advance began to accelerate. Sources, however, more abundant renewable raw materials has become the key to the development of biological base material, how to transform the economic, cellulose and lignin effectively use, is a difficult problem in the field, also is the important direction. On October 16, 2014 held in ningbo international chemical new materials conference, ningbo materials and engineering research institute of the Chinese academy of sciences researcher Zhu Jin of biological materials development present situation, application practice, constraints and introduce attendees attention of potential business opportunities, etc.
Modification of poly (lactic acid) (PLA) research and development, for example. A biodegradable poly (lactic acid) (PLA), renewable raw materials (starch, cellulose), high strength, high modulus, good transparency, carbon reduction and environmental protection, and many other advantages, but at the same time speed is slow, poor transparency after poor heat resistance, heat resistance, impact resistance is poor, the disadvantages of high prices and low melt strength. Therefore, Zhu Jin team improve the heat resistance of poly (lactic acid) (PLA), speed up the crystallization and reduce the cost on the study of modification. By adding nucleating agent, toughening agent, plasticizer, modification of heat resistant poly (lactic acid from more than 15 minutes to half crystallization speed is less than 1 minute, the molding time from more than 10 minutes to less than 1 minute, heat resistant up to 120 ℃ or above, more than 1 times higher impact resistance, heat resistance after the transparency, good. The results have garden in guangzhou jia new materials co., LTD., to realize industrialization.
