摘　　要：本文用生物质填料贝壳粉取代碳酸钙,研究了贝壳粉的取代量和粒径变化,对PVC基复合材料的表观密度、力学、阻燃等性能的影响。实验结果证明,贝壳粉取代量为40%时,复合材料的密度最小,为0.95g·cm^(-3),拉伸强度和冲击强度均达到最大值。从经济效益考虑,贝壳粉粒径以0.018mm为宜。In this paper,shell powder was used as a biomass filler to replace calcium carbonate.The effects of the amount and particle size of shell powder on the flame retardancy,mechanical properties,apparent density and other properties of PVC matrix composites were studied.The results showed that the minimum density was 0.95g/cm^(3),and the tensile and impact strengths reached the maximum values when the shell powder substitution amount was 40%.Considering the economic benefit,the particle size of shell powder was 0.018mm.
