Description

一种改性PP/PE合金材料
技术领域
本发明涉及高分子材料技术领域，具体地说是一种改性PP/PE合金材料。
背景技术
聚丙烯(PP)作为一种通用塑料，具有密度小、无毒、耐腐蚀、力学均衡性好、价格低等优点，但其缺口敏感性特别显著，缺口冲击强度较低，尤其在低温时更为突出。聚乙烯(PE)是一种质轻无毒、具有良好的电绝缘性能和耐化学腐蚀性能的热塑性塑料，其强度较高，耐寒性好，成型加工方便，已广泛应用于建筑、交通运输、电线电缆、化工机械等行业。因此将PP与PE共混，可以制得性能优异的塑料合金，实现树脂的高性能化。由于PP与PE都是结晶性聚合物，它们之间没有形成共晶，而且各自结晶，形成相容性不良的多相体系，两者晶体之间却发生相互制约作用，可破坏PP的球晶结构，PP球晶被PE分割成晶片，使PP不能生产球晶。
发明内容
本发明的目的在于提供一种高性能、低成本的改性PP/PE合金材料。
本发明解决其技术问题所采用的技术方案是：一种改性PP/PE合金材料，其组分按质量百分数配比为：PP 70％～50％、PE 20％～40％、POE 2％～4％、增容剂0～10％、抗静电母粒1.5％～3％、光稳定剂0.1％～1％、润滑剂0.2％～3％、抗氧剂0.2％～0.5％。
所述的PP为聚丙烯塑料。
所述的PE为聚乙烯塑料。
所述的POE为乙烯-辛烯共聚物弹性体。
所述的增容剂为乙烯-丙烯酸甲酯-甲基丙烯酸缩水甘油酯三元共聚物(E-MA-GMA)。
所述的抗静电母粒是由75wt％聚丙烯树脂、20wt％硬脂酸单甘酯抗静电剂和5wt％季戊四醇硬脂酸酯组成的抗静电母粒。
所述的光稳定剂为2-羟基-4-甲氧基二苯甲酮。
所述的润滑剂为聚乙烯蜡、EVA蜡、OP蜡、TAS-2A、乙撑双硬酯酰胺中的一种。
所述的抗氧剂为酚类抗氧剂1076与亚磷酸酯类抗氧剂168的复配物。
上述的一种改性PP/PE合金材料的制备方法，包括以下步骤：
(1)制备抗静电母粒：配料和按重量称取聚丙烯树脂、硬脂酸单甘酯抗静电剂和季戊四醇硬脂酸酯，然后加入高速混合机或超声波发生器中混合10～30分钟，再将混合好的物料加入双螺杆挤出机熔融共混、冷却、切粒、干燥后制得抗静电母粒，待用；
(2)按重量配比称取的PP和PE，加入高速混合机中混合均匀，然后加入按重量配比称取的POE、增容剂、抗静电母粒、光稳定剂、润滑剂和抗氧剂，继续混合2～5分钟；
(3)将上述混合物投入双螺杆挤出机，控制螺杆转速在150～500转/分钟，机筒温度在180℃～240℃，经双螺杆挤出机充分塑化、熔融、复合、机头挤出、拉条、冷却、切粒、烘干、包装即得本发明的一种改性PP/PE合金材料。
本发明的有益效果是，本发明采用PP和PE共混和加入适量助剂的方式制得的一种改性PP/PE合金材料，具有很好兼容特性，而且显著地提高了材料的冲击强度、刚度、耐热性、耐候性等，其综合性能良好，尺寸稳定和加工性能好，并且还具有优异的永久抗静电性能，其表面电阻可达107～109Ω·m。
