摘要
分别以苯乙烯-马来酸酐共聚物(SMA)和环氧树脂EPF51为相容剂,制备了聚氯乙烯/低熔点聚酰胺6/玻璃纤维(PVC/LPA6/GF)复合材料,研究了不同相容剂对PVC/LPA6/GF复合材料结构与性能的影响。结果表明:相容剂EPF51的引入改善了PVC与LPA6的相容性,使PVC/LPA6/GF复合材料的力学性能显著提高,但导致复合材料的维卡软化温度大幅度降低。而相容剂SMA的添加亦显著改善了复合材料的拉伸和弯曲性能,但造成复合材料冲击韧性的下降;此外随着SMA用量的增加,复合材料的维卡软化温度呈先降后升趋势,当其用量为3份时,复合材料的维卡软化温度最低。
The polyvinyl chloride/low melting point polyamide 6/glass fiber（PVC/LPA6/GF） composites were prepared with styrene-maleic anhydride copolymer（SMA） and epoxy resin EPF51 as compatilizer respectively, and the effects of different compatilizer on structures and properties of the PVC/LPA6/GF composites were studied. The results show that the addition of EPF51 improves the compatibility between PVC and LPA6, and the mechanical properties of the PVC/LPA6/GF composites increase obviously, but the Vicat softening temperature of the composites reduces significantly. Moreover, the addition of SMA improves the tensile and bending properties of the composites greatly, but reduces the impact toughness of the composites; in addition, the Vicat softening temperature shows a rising trend after the first drop with the increasing of the SMA content, and the minimum Vicat softening temperature can be obtained when the content of SMA is 3 phr.
