摘　　要：当前聚丙烯降温母粒生产中存在着过氧化物质量分数较低、降温效果较差的问题,对聚丙烯生产效率造成了影响。文章首先介绍聚丙烯降温母粒的基本作用,通过正交试验,对输料段、模头、熔融段温度以及螺杆转速对降温母粒的影响程度进行分析,确定了能够将质量分数控制在0.6%以上的生产工艺条件,最后将添加量作为控制因素,对最优条件下生产的聚丙烯降温母粒进行效果验证。In the current production of polypropylene cooling masterbatch,the mass fraction of peroxide is low and the cooling effect is poor,which has an impact on the production efficiency of polypropylene.This paper first introduces the basic function of polypropylene cooling masterbatch,through the orthogonal test,the feeding section,die head,melting section temperature and screw speed on the cooling masterbatch of the degree of influence was analyzed,to determine the production process conditions can control the mass fraction of more than 0.6%,finally,the amount of addition as a control factor,the effect of polypropylene cooling masterbatch produced under optimal conditions is verified.
