摘要
本研究通过引入甲基丙烯酸甲酯-丁二烯-苯乙烯(MBS)三元共聚物作为增容剂,成功制备了性能增强的聚碳酸酯(PC)/丙烯腈-丁二烯-苯乙烯共聚物(ABS)/玻璃纤维(GF)/MBS与PC/ABS/碳纤维(CF)/MBS共混合金。扫描电子显微镜(SEM)观察液氮脆断断面显示,MBS的加入显著改善了所有合金材料的界面黏附性。力学性能测试结果表明,添加质量分数1%的MBS后,PC/ABS/GF合金的拉伸强度、拉伸模量和缺口冲击强度分别提高了6.52%、53.87%和0.22%;在PC/ABS/CF合金中,添加质量分数3%MBS后,这些性能分别提升10.14%、45.10%和0.66%。然而,由于MBS的低熔点,其加入对合金的热稳定性产生了一定负面影响,导致热性能下降。研究表明,MBS的引入显著增强了PC/ABS基体的界面结合力和力学性能。
In this study,enhanced polycarbonate(PC)/acrylonitrile-butadiene-styrene copolymer(ABS)/glass fiber(GF)/MBS and PC/ABS/carbon fiber(CF)/MBS blends were successfully fabricated by introducing methyl methacrylate-butadiene-styrene(MBS)copolymer as a compatibilizer.The observations of liquid nitrogen fractured surfaces by scanning electron microscopy(SEM)reveal that the addition of MBS could significantly improve the interfacial adhesion of all alloy materials.The mechanical performance tests indicat that the addition of 1%MBS to the PC/ABS/GF blend could increase the tensile strength,tensile modulus,and notched impact strength by 6.52%,53.87%,and 0.22%,respectively.In the PC/ABS/CF blend,the addition of 3%MBS could improve 10.14%,45.10%,and 0.66%of these properties,respectively.However,due to the low melting point of MBS,its incorporation has a negative impact on the thermal stability of the alloys,leading to a decrease of thermal performance.The study shows that the introduction of MBS could significantly enhance the interfacial bonding and mechanical properties of the PC/ABS matrix.
