Description

一种聚烯烃用高浓度抗静电母料及制备方法
技术领域
本发明涉及一种聚烯烃用高浓度抗静电母料及其制备方法，可应用于塑料加工行业的塑料制品的改性。 
技术背景
由于聚烯烃抗静电剂熔点低，其熔体极具润滑性，因此在螺杆挤出机挤出造粒过程中，抗静电剂与聚烯烃树脂很难均匀混容，所以现有的抗静电母料普遍浓度较低，在聚烯烃抗静电塑料制品(尤其是PP、HDPE厚壁制品)中使用很不经济。 
发明内容
针对现有技术中的问题，本发明的目的是提供一种聚烯烃用高浓度抗静电母料及制备方法，采用本方法得到的抗静电母料具有浓度高、改善物料均匀塑化混炼条件、工艺简单等优点，制备过程避免了使用螺杆挤出机，完全克服了传统制备方法中，物料体系在螺杆挤出加工条件下过度润滑的缺陷。 
本发明涉及一种聚烯烃用高浓度抗静电母料，包含有共混的以下组份： 
Figure BSA0000099415520000011
以上所述线性低密度聚乙烯a的熔体流动速率为2-5g／10min，所述线性低密度聚乙烯b的熔体流动速率为20-30g／10min，所述线性低密度聚乙烯c的熔体流动速率为2～10g／10min，所述抗静电剂为有机胺类和单甘脂类非离子型表面活性剂中的一种或多种，所述无机粉体材料包括碳酸钙、硫酸钡、滑石粉、高岭土、二氧化硅、硅灰石、云母等。 
本发明涉及一种聚烯烃用高浓度抗静电母料的制备方法，其特征在于制备方法为：将上述各组分投入高速混合机中，经高速混合，达到各组分充分均匀熔融，然后出料冷却，等充分固化后，再粉碎过筛，得到成品。 
优点：由于避免了使用螺杆挤出机，完全克服了物料体系在受热加工条件下过度润滑的不利影响；大大改善了物料均匀塑化混炼的条件，工艺问单、经济。 
本发明是通过以下方式实施的： 
一种聚烯烃用高浓度抗静电母料，由如下组份组成：一种线性低密度聚乙烯a重量分数10～40％，熔体流动速率为2-5g／10min；另一种线性低密度聚乙烯b重量分数10～40％，熔体流动速率为20-30g／10min；一种低密度聚乙烯c重量分数15～30％，熔体流动速率为2～10g／10min；一种或多种抗静电剂重量分数20～40％，抗静电剂为氧乙基胺类和甘油脂肪酸脂类非离子型表面活性剂；一种或多种无机粉体材料重量分数5～30％，包括碳酸钙、硫酸钡、滑石粉、高岭土、二氧化硅、硅灰石、云母等。 
将上述各组分投入高速混合机中，经高速混合，达到各组分充分均匀熔融，然后出料冷却，等充分固化后，再粉碎过筛，得到母料成品。用所得母料按特定的比例加入聚烯烃塑料材料中一起加工成抗静电塑料制品，其制品的表面电 阻率ρ可达108-1010Ω·m。
