Description

一种高透明聚丙烯的配方及其制备方法
技术领域
本发明涉及聚丙烯生产技术领域,尤其涉及一种高透明聚丙烯的配方 及其制备方法。
背景技术
聚丙烯透明料效果与聚苯乙烯(PS)、聚碳酸酯(PC)、聚酯(PET)、聚 氯乙烯(pvc)等常用透明树脂相当,应用领域可以扩展到玩具、包装材料、 医疗机械、工业零部件等方面。2013年中国透明聚丙烯消费量约在70 万吨,2016年透明聚丙烯消费量提升约至120万吨,属于近年来需求量增 长较快的PP种类之一。目前煤化工路线生产聚烯烃企业尚无涉及,进口 货源主要来自韩国。
发明内容
本发明所要解决的技术问题是克服现有技术中存在的不足,提供一种 高透明聚丙烯的配方及其制备方法。
本发明是通过以下技术方案予以实现:
一种高透明聚丙烯的配方,包括如下重量百分比的配方组分为:
聚丙烯:40-50%;
聚乙烯:20-30%;
Z-N催化剂:5-10%;
发泡剂:1-5%。
一种高透明聚丙烯的制备方法,包括以下步骤:
(1)将配方量的聚丙烯、聚乙烯、Z-N催化剂在喂料系统中1500r/min 的转速下混料2-4min混合;
(2)注入配方量的发泡剂,在同样的转速条件下继续混料2-4min,得到预混料;
(3)通过双螺杆挤出机的剪切作用,使预混料充分熔融混合;
(4)熔体在水下切粒机模板处被切粒;
(5)切出的聚丙烯颗粒经振筛机筛分,并将筛分的颗粒分类,将不 同粒径的产品称重包装。
本发明的有益效果是:
本发明聚丙烯复合材料的制备方法只需按配方将各组分混合并在适 当的温度下挤出造粒即可得到产品,在挤出过程中,各种原料发生协同作 用,赋予了该聚丙烯复合材料具有优异的无卤阻燃、耐低温的性能,并且 制备方法工艺简单,条件易控,成本低廉,对设备要求低的特点,适于工 业化生产。
