摘　　要：采用双螺杆挤出机熔融挤出共混的方法,在较高螺杆转速条件下研究了CaCO3表面处理剂品种、CaCO3颗粒直径及其含量等因素对ABS/弹性体/CaCO3共混材料力学性能和加工流动性能的影响。结果表明,在CaCO3颗粒直径1.08～1.96μm、C型表面处理剂、螺杆转速480 r/min、220℃的共混条件下,可制得综合力学性能较好的ABS/高胶粉(GP)/CaCO3(质量比62.9∶17.1∶20)和ABS/EVA/CaCO3(质量比74.6∶20.4∶5)共混材料。The effect of CaCO3 surface treated agents, CaCO3 particle diameter and content on mechanical properties and the malt flow rate of ABS/elastomer/CaCO3 blending material is investigated by means of melt extrusion and blending with twin-screw extruder. The results show that the blending materials with better mechanical properties such as ABS/GP/CaCO3 （mass ratio： 62.9/17.1/20） and ABS/EVA/CaCO3 （ mass ratio ： 74.6/20.4/5） can be obtained under the conditions of CaCO3 particle diameter 1.08-1.96μm, screw rotation speed 480 r/min and extrusion temperature 220℃.
