热塑性淀粉塑料的研究概况
摘要
随着塑料产量的不断增长和用途的不断扩大,塑料带给人们便利的同时,也给环境带来大量的固体废弃物形成严重的白色污染,已成为世界性公害。现行塑料制品的原料是不可再生资源——石油,而全世界的石油储量大约只能再用40多年。发展非石油基聚合物如淀粉基塑料,研制可在自然环境中降解的可再生资源代替石油生产塑料,已成为热门课题。
本文简述了淀粉基塑料的四大分类，对淀粉降解塑料的国内外研究进展进行了综述,指出全淀粉降解塑料研究中存在的问题和发展趋势,并对淀粉基塑料未来的发展趋势进行了展望,认为全淀粉降解塑料是最有发展前景的生物降解塑料之一。

Research of water resistance of thermoplastic starch plastics
Abstract
Yield increasing and expanding the use of plastic, plastic tape convenient to people at the same time, but also to the formation of large amounts of solid waste on the environment serious white pollution, has become a universal nuisance. Current plastics raw material is a non-renewable resource--petroleum, about oil reserves can only be used around the world for more than 40 years. Develop non-petroleum based polymers such as starch based plastics, degradation in the natural environment and renewable resources developed plastic instead of the oil, has become a hot topic.
This paper describes the four classification of starch-based plastic, reviewed the research progress of degradable plastics of starch, pointed out that all problems in the research and development of degradable plastics of starch trend and prospect on the future development trend of starch-based plastic, think full-degradable plastics of starch is one of the most promising bio-degradable plastics.
