摘　　要：用正交试验设计的方法研究了稀土复合热稳定剂、乙烯–乙烯乙酸酯共聚物(EVAC)、轻质CaCO3以及聚氯乙烯(PVC)异型材废料用量对PVC复合材料性能的影响。结果表明,轻质CaCO3用量为复合材料缺口冲击强度的主要影响因素,PVC异型材废料用量是拉伸强度的主要影响因素。考虑缺口冲击强度要求,最佳配比为稀土复合热稳定剂3.5份,EVAC 13份,轻质CaCO38份和PVC异型材废料35份。By using orthogonal experiment design method, the ettects ot the amounts ot rare earta neat stabilizer, emy^ene- vinyl acetate copolymer（EVAC） , precipitated calcium carbonate, PVC profiles scraps on the properties of the composites were discussed.The results show that the usage of precipitated calcium carbonate is the key factor to notched impact strength of the composite, the usage of PVC profiles scraps is the key factor to tensile strength.According to the request of notched impact strength,the optimum formulation is heat stabilizer 3.5 phr, EVAC 13 phr, precipitated calcium 8 phr and PVC profiles scraps 35 phr.
