发明内容
本发明主要解决的技术问题是提供一种很适合用于塑料改性方面，由于其压实的形态、更高的复合量，使塑料的分散性好，耐磨，耐刮擦，易喂料，热稳定性好的POE滑石粉母粒。
为达到上述目的，本发明采用的技术方案是：一种POE滑石粉母粒，以重量百分比计，包括如下组分：聚烯烃弹性体POE19.5～20.5％、聚乙烯4.5～5.5％、硬脂酸钙0.5～1.5％和滑石粉73.5～74.5％；制备时，先投入滑石粉，再加入聚烯烃弹性体混合，然后再加入聚乙烯和硬脂酸钙，混合物密炼加温至150℃，加热10分钟，然后进入双螺杆挤出机混炼；混炼后挤出、冷却和切粒。
优选的，所述聚烯烃弹性体POE选用聚烯烃弹性体8150；所述聚烯烃弹性体8150是乙烯辛烯共聚物，具有优异的流动性，在与聚乙烯共混之后会具有超级的抗冲击性能。
优选的，所述滑石粉包括：氧化镁:32％、氧化钙:0.25％、三氧化二铝:0.30％、三氧化二铁:0.30％、烧失量：9％、二氧化硅:58.15％组成的T-7型号滑石粉。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：
本发明所述的POE滑石粉母粒，由于采用的滑石粉其超薄度、超细度和均匀的粒径分布，很适合用于塑料改性方面，由于其压实的形态、更高的复合量，能够提高塑料的分散性，耐磨，耐刮擦，易喂料，热稳定性好。
具体实施方式
下面结合具体实施例对本发明作进一步的详细说明。
