Description

三层结构防腐钢质管道聚丙烯夹克料及其制备方法
技术领域：
本发明涉及钢质管道外防腐技术领域，尤其涉及一种防腐蚀耐磨涂料三层结构防腐钢质管道聚丙烯夹克料及其制备方法。

钢质管道外防腐技术领域包括：(1)用作输送较高温度介质的防腐管线；(2)用作地表温度较高，日照时间较长的沙漠地区的防腐管线；(3)用于防腐管线的地下穿越；(4)用作加压站附近防腐管线。
在上述技术领域中，现在主要使用聚丙烯(PP)材料，PP是一种半结晶性材料，它比聚乙烯(PE)要更坚硬并且有更高的熔点。由于均聚物型的普通PP温度高于100度时非常脆，因此许多商业的材料PP是加入4～10％的无规则共聚物或更高比率烯含量的钳段式共聚物。共聚物型的材料PP的热扭曲温度(100度)、透明度、光泽度、刚性等都较低，虽其具有强的抗冲击强度，但是不能满足聚丙烯防腐的防腐标准。
