摘要
采用直接共混挤出法、母粒法和二次挤出法3种加工工艺对纳米CaCO3/高抗冲聚苯乙烯(HIPS)/丙烯腈-丁二烯-苯乙烯共聚物(ABS)复合材料的力学性能进行了研究。结果表明,采用母粒法制备的纳米CaCO3/HIPS/ABS复合材料的力学性能优于直接共混挤出法和二次挤出法的。此外,采用母粒法探讨了纳米CaCO3含量对纳米CaCO3/HIPS/ABS复合材料力学性能的影响。结果表明,纳米CaCO3/HIPS/ABS复合材料的缺口冲击强度在纳米CaCO3质量分数6%时达到最大值,拉伸强度和弯曲强度随着纳米CaCO3含量的增加而逐渐下降。
The mechanical properties of nano-CaCO3/HIPS/ABS composites were studied using three processing technologies including direct blending extrusion, master- batch method and twice extruding method. The results show that mechanical properties of thenano-CaCO3/HIPS/ABS composites prepared by masterbatch method are better than those of the composites prepared by direct blending extrusion and twice extruding meth- od. Besides, the effect of CaCO3 content on mechanical properties of the nano-CaCO3/ HIPS/ABS composites was studied by masterbatch method. The results indicate that not- ched impact strength of the nano-CaCO3/HIPS/ABS composites reaches a maximum value when the content of nano-CaCO3 is 6%, and the tensile strength and flexural strength de- crease slightly with the increase of nano-CaCO3 content.
