电缆用聚丙烯的配方设计

Formula Design for Polypropylene in Cables

对国产五种聚丙烯树脂,四种增韧改性剂,以及三种弹性体进行了大量分析对比性研究,从中筛选出性能相对满意的基体材料,然后合理配方,并加入适量增韧剂、成核剂及助剂等,共混后制得的产品通过力学性能、电性能及挤出性能等项测试,质量达到国家标准及邮电部YD322—84标准。

This paper deals with five pp matrix resins,four toughing promoters and three elastomers, and selects out the base material of satisfying propety,then makes suitable farmula by adding certain quantity of foughing agent,nucleating agent and additives. From the test on physical property,the product proves to be able to meet GB and YD322-84
