摘　　要：以亚克力人造石废粉对ABS进行填充改性,采用熔融共混法制备了ABS基复合材料。通过力学性能测试研究了苯乙烯-马来酸酐共聚物(SMA)、ABS接枝马来酸酐(ABS-g-MAH)和钛酸酯偶联剂三种改性剂的引入对ABS/亚克力人造石废粉复合材料力学性能的影响。结果表明:改性剂SMA、ABS-g-MAH和钛酸酯偶联剂均能在一定程度上改善ABS/亚克力人造石废粉复合体系的界面相容性,其最佳用量分别为4%、4%和3%,其中SMA对复合材料的改性效果优于ABS-g-MAH和钛酸酯偶联剂。当SMA用量为4%,亚克力人造石废粉用量为20%,复合材料的拉伸强度和弯曲强度达到最高值,分别为42.17 MPa和83.43 MPa。ABS/yakeli artificial stone waste power composites were prepared by melt blending method. The effects of styrene-maleic anhydride copolymer(SMA), maleic anhydride grafted ABS(ABS-g-MAH)and titanate coupling agent on mechanical properties of the composites were investigated by mechanical properties test. The results indicated that both the SMA, ABS-g-MAH and titanate coupling agent could improve the interfacial compatibility of the ABS/yakeli artificial stone waste power composites to some extent, the optimal dosage of three modifiers were 4%, 4% and 3% respectively, and the modified effect of SMA on the composites was better than that of ABS-g-MAH and titanate coupling agent. The tensile strength and bending strength of ABS/yakeli artificial stone waste power composites reached the highest value, which were 42.17 MPa and 83.43 MPa respectively when the dosage of SMA and yakeli artificial stone waste power were 4% and 20%.
