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CaCO3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CaCO3复合材料,探究PBS、BF及纳米CaCO3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CaCO3复合材料进行测试和表征。结果表明:加入PBS、纳米CaCO3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CaCO3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8.416 5 kJ/m2。研究可为生物可降解的汽车复合材料制备提供参考。

Abstract

In this study, acrylonitrile-butadiene-styrene (ABS) was used as the matrix, and polybutylene succinate (PBS), bagasse fiber (BF), and nano-CaCO3 were used as fillers to prepare high-performance and biodegradable ABS/PBS/BF/nano-CaCO3 composites by melt blending, to explore the effects of the addition of PBS, BF, and nano-CaCO3 on the mechanical properties and thermal stability of the composites, and the ABS/PBS/BF/nano-CaCO3 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-CaCO3 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-CaCO3 was 5%, and the tensile strength and impact strength of the materials were 52.74 MPa and 8.416 5 kJ/m2, respectively. The study could provide a good basis for the biodegradable automotive composites preparation.
