摘要/Abstract

摘要： 将用偶联剂和增容剂改性的多层塑料复合板固体废料粉末（GFRP）加入到聚丙烯（PP）基体中，制备复合材料。采用差示扫描量热仪（DSC）、扫描电子显微镜（SEM）研究了复合材料的微观结构和热性能，并测试了材料的力学性能。研究结果表明，当1 %硅烷偶联剂KH570处理的GFRP的含量为20份（质量份，下同），增容剂马来酸酐接枝聚丙烯（PP-g-MAH）含量为2份时，复合材料的冲击强度显著提高，弯曲强度与弯曲模量也有一定程度的提高，拉伸强度下降不大。SEM观察结果表明，PP/改性GFRP/PP-g-MAH复合材料在断裂过程中发生塑性变形。DSC分析表明，GFRP的加入没有改变PP的晶型。

Abstract: PP was filled with powder of waste plastic multilayer plates(GFRP), a coupling agents and a compatibilizer forming a composite, which was characterized using DSC，SEM, and the mechanical testings. When the content of GFRP (modified by 1 wt % KH570) and the compatibilizer was 20 phr and 2 phr, respectively, the impact strength of the composites increased markedly, the flexural strength and modulus also increased based on neat PP. SEM indicated that plasticity deformation occurred during fracture process of the composite. DSC showed that the addition of GFRP didn't changed crystal form of PP.
