抗静电阻燃聚丙烯(PP)的研究
Anti-electrostatic and flame-retardant polypropylene
【摘要】 聚丙烯是一种易燃高聚物,同时也是电的优良绝缘体,易产生静电,由此产生的火灾和爆炸事件时有发生,因此对某些特殊用途的聚丙烯必须进行抗静电和阻燃处理。选择适当的抗静电剂和阻燃剂,以不同的量加入聚丙烯树脂中,通过大量的试验,找出抗静电剂含量与聚丙烯表面电阻的关系、阻燃剂含量与拉伸强度的关系及阻燃性能的关系和阻燃剂之间协同作用的关系等。经过优化设计确定理想的配方和工艺条件,研制出满足特殊用途且符合工程要求的抗静电阻燃聚丙烯。所制得的聚丙烯的拉伸强度、氧指数和表面电阻分别为34.7MPa, 27.5和2.76×10-8Ω。
