Description

一种免喷涂聚丙烯组合物及其制备方法 技术领域
本发明涉及高分子材料技术领域，具体涉及一种具有美学外观的免喷涂聚丙烯组合物及其制备方法。
背景技术
聚丙烯PP，半结晶性塑料，具有密度低、易加工等特点，已成为车用塑料中用量最大的品种。然而聚丙烯表面能低，喷漆困难，喷漆前需结合复杂的聚丙烯表面前处理，同时喷漆不良率高，对人的健康和环境的影响大。
中国专利CN 103112096 B采用在挤出机口模处加装超声波设备，改善聚酯与铝粉的亲和力，从而减低注塑成型过程中的流痕和熔接线问题；中国专利CN 103910941 B通过采用相容化技术，通过填料与极性相容剂形成的交联网络结构，使颜料分布随熔体流动发生变化的行为受到了限制，从而降低熔接线和流痕缺陷；中国专利CN 102643505 B采用具有磁性的金属颜料母粒方法，通过在成型时外加磁场，控制金属颜料的取向从而降低熔接线和流痕。
然而上述专利公开的方法中，通过添加超声波和外加相容剂的手段，都属于限制成型过程中效果颜料的翻转，但这种限制却十分有限，难以达到真正的消除流痕和熔接线缺陷，同时对注塑成型工艺的要求非常高。而通过添加磁性母粒的方法，母粒可选的效果颜料非常局限，同时要求成型设备具有外加磁场的功能。因此本领域尚需开发一种制备工艺简单且对成型工艺和模具要求不高的免喷涂聚丙烯材料，从而更能适用于汽车内外饰件或家电等其它应用领域。

上述免喷涂聚丙烯组合物的制备方法，包括如下步骤：
按照配比称取聚丙烯树脂、效果颜料、增韧剂、填料及助剂进行混合均匀后，加入双螺杆挤出机中，进行熔融混炼，熔融混炼温度为170℃～220℃，螺杆转速为350转/分～450转/分，挤出造粒，得到免喷涂聚丙烯组合物。

2)本发明的制备工艺简单，对模具设计和成型工艺的要求不高，可应用于结构较为复杂的制件，扩宽了免喷涂产品的应用领域；同时也可应用于制备汽车内外饰件以及家电等领域产品，具有类似喷涂的美学效果。
