Description

高分散高填充滑石粉改性聚丙烯母粒及其制备方法
技术领域
本发明涉及一种粉体填充聚合物母粒及其制备方法,尤其涉及一种高分散高填充滑石粉改性聚丙烯母粒及其制备方法,属于复合高分子材料及其加工技术领域。
背景技术
聚丙烯蜂窝板由于强度高且质轻,无毒无害及不含ELV禁用物质,可广泛应用于汽车的行李箱盖板、座椅背板、侧围、顶棚等汽车内饰部件上。但纯聚丙烯制成的蜂窝板,其强度往往达不到主机厂要求,需要通过添加滑石粉、云母粉等增强物质才能满足主机厂对聚丙烯蜂窝板刚度及弯曲模量的要求。同时随着人们生活水平的提高和市场竞争的加剧,各汽车厂对材料气味性的要求越来越高,目前中石化和中石油生产的聚丙烯全新原料本身的气味性,一般都在3.8-4.0之间(以大众汽车标准为例),都不能直接达到主机厂对气味的要求(≦3.5),必须添加除味剂等来改善气味才能满足主机厂对气味性的要求。
因目前的填充材料基本都为粉体材料,如增强材料滑石粉、云母粉、碳酸钙等,如助剂偶联剂、分散剂、抗氧剂、相容剂、润滑剂和除味剂等,大量的粉体材料很难直接添加进树脂基体中,其含有大量粉体的树脂很难进行挤出、注塑、吹塑等,难以满足生产工艺要求,需要将粉状填充成份制成含有树脂载体的颗粒状加入基体树脂中,才能满足工艺生产的要求。但目前常见的滑石粉填充母粒,在实际用于生产聚丙烯蜂窝板时经常会出现麻点,造成大量废次品,同时生产过程中,麻点对磨砂辊造成很大损伤,这是因为所使用的滑石粉填充母粒中,滑石粉的分散不好,在载体树脂中容易团聚成很大的颗粒,从而使其应用在聚丙烯蜂窝板中时出现麻点。
发明内容
