More Information
Summary:A mother particles for the photogradable polypropylene plastics is prepared from polypropylene resin (35-50 wt.%), modified calcium carbonate (20-35), talc powder (20-30), coupling agent (1-2), stearic acid (1-2), lubricant (1-2), and light and oxygen sensitizer (0.3-2). Its advantage is high degradation speed under action of light, oxygen and high temp. 本发明涉及一种光降解聚丙烯塑料母粒，其特征在于：由下列组成物及重量百分比构成，聚丙烯树脂35％-50％，改性碳酸钙 20％-35％，滑石粉20％-30％，偶联剂1％-2％，硬脂酸1％-2％，润滑剂1％-2％，光氧敏化剂0.3％-2％。本发明的优点是能在自然状态下由光、氧、热等作用下，加速塑料的降解，控制塑料制品带来的白色污染。
