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。 |
