Description

一种长玻纤增强热塑性材料
技术领域
本发明属于复合材料领域，尤其涉及一种长玻纤增强热塑性材料。
背景技术
长纤维增强热塑性材料和普通的纤维增强热塑性材料相比较而言，采用最多的基体树脂是PP、其次是PA、也有使用PBT、PPS、SAN等树脂。这种材料的成型过程是：将聚合物基体颗粒(主要是PP)和添加剂输送到重力混合计量单元中， 根据部件的机械性能要求进行材料的混配，经混配好的原料再被送入双螺杆挤出机中进行塑化，熔融的混合物通过一个薄膜模头形成类似瀑布的聚合物薄膜，该聚合物薄膜直接被送入到双螺杆混炼挤塑机的开口处。此时，玻璃纤维粗纱通过特别设计的粗纱架，在经过预热、分散等程序后被引入到聚合物薄膜的顶端与薄膜汇合一同进入到双螺杆挤塑机中，由螺杆切割粗纱，并把它们柔和地混合到预熔的聚合物当中，然后直接送入压制模具中成型或者推压进注射模具成型。在这个过程中，如果pp树脂浸渍越均匀、越完全，则各玻璃纤维之间的缠结力、相互作用力越大，使得玻璃纤维。传统的长玻纤增强聚丙烯复合材料生产时严重阻碍了玻纤增强聚丙烯复合材料力学性能的提升。
发明内容
本发明提供了一种长玻纤增强热塑性材料，该复合材料克服了现有技术的不足，具有很好的力学性能。
为实现以上目的，本发明采用以下技术方案：

相容剂 2%-5%
偶联剂 0.2%-2%
热稳定剂 0.9%-2%。
以上所述组分中，所述相容剂为极性单体接枝聚合物型相容剂，优选聚丙烯马来酸酐接枝，恶唑啉改性聚丙烯或丙烯酸缩水甘油酯接枝的聚丙烯，所述偶联剂为KH550，所述热稳定剂为无毒有机锡。
本发明的有益效果：本发明所得长玻纤增强热塑性材料既解决了聚丙烯树脂与尼龙树脂之间的分层问题，实现两者优良的混合，改善了复合材料后续的相容性及分散性问题，而且本发明的复合材料具有很好的力学性能。
