为研究无机刚性粒子对聚碳酸酯/(丙烯腈-苯乙烯-丙烯酸丁酯)三元共混物合金(PC/ASA)的力学性能的影响,采用熔融共混方法制备了PC/ASA/SAN/TiO_2和PC/ASA/SAN/CaCO_3两种复合材料,并对其缺口冲击,拉伸,熔融指数测试和冲击断面的形貌观察,分析研究了不同含量,不同粒径的无机填料对PC/ASA合金增韧,增强,流动性能的影响.试验结果表明,CaCO_3体系和TiO_2体系冲击强度均随填料用量增加而明显降低;无机填料/PC/ASA复合材料的力学性能总体呈下降趋势,流动性能则随无机填料含量的增大而显著增大.
In order to investigate the mechanical properties of polycarbonate/(acrylonitrile-styrene-acrylic) terpolymer (PC/ASA) alloy reinforced with inorganic particles, both PC/ASA /SAN /TiO_2 and PC/ASA/SAN/ CaCO_3 were prepared by the melt blending method. The effect of the mass fraction of filler and the particle size on the toughing and strengthening of PC/ASA matrix were studied based on the results of mechanical properties testing and the observation of the impact fracture surface morphology of the composites. The result shows that inorganic filler/PC/ASA mechanical properties of composite materials is the overall downward trend; While inorganic filler content increased, the flow property of composite increases significantly. Inorganic filler makes PC/ASA matrices not be toughener and enhance the effect of strengthening, but enhance the flowing property of PC/ASA/Composite material. Inorganic nano-particles/PC/ASA composite materials is widely used in electronic, outdoor decoration materials and other fields.
