摘　　要：研究以丙烯腈-丁二烯-苯乙烯(ABS)为基体,以聚丁二酸丁二醇酯(PBS)、甘蔗渣纤维(BF)、纳米CaCO_(3)为填料,通过熔融共混法制备性能优良且可降解的ABS/PBS/BF/纳米CaCO_(3)复合材料,探究PBS、BF及纳米CaCO_(3)的加入量对复合材料的力学性能和热稳定性的影响,采用傅里叶变换红外光谱(FTIR)、热重(TG)、X射线衍射(XRD)、扫描电镜(SEM)等对ABS/PBS/BF/纳米CaCO_(3)复合材料进行测试和表征。结果表明:加入PBS、纳米CaCO_(3)和改性BF可以提高纤维与基体结晶性、相容性和热稳定性;PBS质量分数为5%、BF质量分数为5%、纳米CaCO_(3)质量分数为5%时,复合材料的性能最佳,材料的拉伸强度和冲击强度分别为52.74 MPa和8.4165 kJ/m^(2)。研究可为生物可降解的汽车复合材料制备提供参考。In this study,acrylonitrile-butadiene-styrene(ABS)was used as the matrix,and polybutylene succinate(PBS),bagasse fiber(BF),and nano-CaCO_(3)were used as fillers to prepare high-performance and biodegradable ABS/PBS/BF/nano-CaCO_(3)composites by melt blending,to explore the effects of the addition of PBS,BF,and nano-CaCO_(3)on the mechanical properties and thermal stability of the composites,and the ABS/PBS/BF/nano-CaCO_(3)composites were tested and characterized by Fourier transform infrared spectroscopy(FTIR),thermogravimetric(TG),X-ray diffraction(XRD)and scanning electron microscope(SEM).The results showed that the addition of PBS,nano-CaCO_(3)and modified BF could improve the fiber-matrix crystallinity,compatibility and thermal stability.The best performance of the composites was achieved when the mass fraction of PBS was 5%,the mass fraction of BF was 5%,the mass fraction of nano-CaCO_(3)was 5%,and the tensile strength and impact strength of the materials were 52.74 MPa and 8.4165 kJ/m2,respectively.The study could provide a good basis for the biodegradable automotive composites preparation.
