摘　　要：通过熔融法分别制备了含氯化聚乙烯(CPE)和氧化锑(Sb2O3)阻燃剂的PVC/ABS复合材料,探讨添加不同含量的阻燃剂对复合材料的热稳定性、阻燃性能以及力学性能的影响。实验结果表明:CPE的加入使复合材料形成了交联网状结构,从而有效地提高了其力学强度。在加入Sb2O3后,由于无机纳米粒子较低的热导率,使得燃烧过程中热传递较慢。热力学结果表明,CPE和Sb2O3阻燃剂能有效地提高PVC/ABS复合材料的热稳定性以及阻燃性能。同时,CPE可以提高其力学性能,Sb2O3可以提高其抗拉强度,但由于不同浓度的Sb2O3粒子在基体中的分散性不同,其在高浓度下的冲击强度相比于纯PVC/ABS复合材料明显下降。PVC/ABS composites containing chlorinated polyethylene(CPE) and Sb2O3 flame retardants were prepared by melting method, and the effects of adding different flame retardants to composite materials were discussed. The influence of thermal stability, flame retardancy and mechanical properties. The experimental results show that the addition of CPE makes the composite material form a cross-linked network structure, thereby effectively improving its mechanical strength. After adding Sb2O3, due to the lower thermal conductivity of inorganic nanoparticles, the heat transfer during the combustion process is slower. Thermodynamic results show that both CPE and Sb2O3 flame retardants can effectively improve the thermal stability and flame retardancy of PVC/ABS composites. At the same time, CPE can improve its mechanical properties, Sb2O3 can increase its tensile strength, but due to the different dispersion of Sb2O3 particles of different concentrations in the matrix, its impact strength at high concentrations is significantly lower than that of pure PVC/ABS composites.
