可降解塑料分类及生产应用研究

Research on the Classification and Production Application of Degradable Plastics

随着科技发展和人们生活质量提高,对环保要求逐年增长。生产完全可降解塑料,从根本上治理白色污染是一直以来研究的热点。以可降解塑料降解程度或深度为主线,研究不同类型可降解塑料含义、性能。完全生物降解塑料,最终生成二氧化碳和水,是一类无毒无害的高分子聚合物塑料。重点研究完全降解塑料PLA、PBAT、PBS生产方法及工艺,展望可降解生物塑料探索方向。

With the development of science and technology and the improvement of people’s life quality,the demand for environmental protection is increasing year by year.To produce fully degradable plastics.The fundamental treatment of white pollution has always been a research hotspot.this paper takes the degradation degree or depth of degradable plastic as the main line,the meaning and performance of different types of degradable plastics were studied.Fully biodegradable plastics,and eventually carbon dioxide and water,It is a kind of non-toxic and harmless polymer plastic.The production method and technology of PLA,PBAT and PBS are mainly studied.The research direction of biodegradable plastics is prospected.
