摘要: 研究了3种不同结构的相容剂对聚对苯二甲酸丁二醇酯/丙烯腈-丁二烯-苯乙烯三元共聚物(PBT/ABS)共混合金的力学性能和熔体流动速率的影响,并采用扫描电镜和差示扫描量热仪对PBT/ABS共混合金的相界面、相容性及结晶度进行了表征。结果表明,带有环氧官能团的相容剂KS-TD-00202能有效地提高PBT/ABS共混合金的相容性,在提高共混合金缺口冲击强度的同时,不降低拉伸强度和弯曲强度,也不影响共混合金的加工流动性,同时提高了PBT在共混合金中的结晶度。

Abstract: The effect of three kinds of compatibilizers on the mechanical property and melt flow rate of poly(butylenes terephthalate)/acrylonitrile-butadiene-styrene copolymer (PBT/ABS) alloys was studied. The interface property, compatibility, and crystallinity of PBT/ABS alloy were characterized using scanning electron microscope (SEM) and differential scanning calorimeter (DSC). It was found that the compatibility of PBT/ABS alloys could be effectively improved by adding a compatibilizer containing epoxy functional groups, KS-TD-00202, as a result, the notched impact strength was obviously enhanced without reducing the tensile strength, flexural strength, and processing properties. In addition, the crystallinity of PBT in the alloy was also increased.
