| 摘 要： | 采用环氧树脂(E51)、马来酸酐接枝聚丙烯(PP-g-MAH)或苯乙烯-顺丁烯二酸酐(马来酸酐)共聚物(SMA)增容PP与丙烯腈-苯乙烯共聚物(AS)共混体系,重点研究了环氧树脂含量、固化剂(2E4MZ)以及热处理对PP/AS合金体系力学性能的影响,并辅以扫描电镜(SEM)进行微观结构分析以及差示扫描量热仪(DSC)进行结晶行为分析。研究表明,环氧树脂的加入提高了体系的相容性,材料的性能尤其是刚度得到较大提高,当环氧树脂用量为3份,固化剂用量为环氧树脂用量的4%时,体系的刚性最佳,弯曲模量高达1.75 GPa;热处理后,合金体系的结晶度提高,刚性进一步提高至1.84 GPa。

| Abstract: | The composites of PP/AS were prepared by melting extrusion technology with the compatibilizer(PP-g-MAH,SMA)or epoxy resin(E51).The effects of epoxy resin,curing agent(2E4MZ)and heat treatment on mechanical property of the composites were studied systematically.The micro morphology was observed by using scanning electron microscopy(SEM)and the crystallization was studied by differential scanning calorimetry(DSC).The results showed that the compatibility of components and the material properties were improved... |
