摘要
对纳米碳酸钙(nano-CaCO3)表面恰当处理后,与聚氯乙烯(PVC)、氯乙烯-丙烯酸丁酯共聚弹性体(VC-BA)组成三元复合体系,详细研究了该复合体系的加工工艺及其组成与所制材料力学性能之间的关系。当复合母粒中VC-BA与CaCO3的质量比为2∶3时,材料的力学性能最佳,CaCO3对材料具有补强作用,并且CaCO3和VC-BA能协同增韧PVC,使材料的冲击强度得到大幅度提高,当PVC和复合母粒质量比为100∶20时,材料的冲击强度达到49.5kJ/m2,拉伸强度仍高达51.0MPa。
Poly（vinyl chloride）/（vinyl chloride-butyl acrylate）/nanometrie calcium carbonate composite was prepared on the basis of investigating nanoCaCO3 surface treatment and the processing of （PVC）/ VC-BA/nanoCaCO3 ternary-phase composite, and the relationship between the mechanical properties and the processing and composition was also studied in detail. The best general mechanical properties of the prepared composite can be gotten when the mass proportion of VC-BA to nanoCaCO3 in the master batch was 2 ： 3; the reinforcing effect of nanoCaCO3 on PVC and good cooperation effect of nanoCaCO3 and VC-BA on the toughness can be obtained during this forming process, the impact strength of PVC/VC-BA/nanoCaCO3 composite can be improved greatly, arriving at 49.5 kJ/m^2 when the proportion of PVC to the master batch（ VC-BA： nanoCaCO3 = 2：3） was 100：20,at the same time the tensile strength of the composite can also reach 51.0 MPa.
