摘要
通过把改性碳酸钙晶须以不同含量加入到聚丙烯中,在二次开模条件下制备微发泡PP/碳酸钙晶须复合材料,分析不同含量的碳酸钙晶须对微发泡复合材料发泡行为的影响。结果表明:当碳酸钙晶须质量含量为10%时,微发泡复合材料的泡孔分散度为6.25、泡孔直径25.27μm左右、泡孔密度为4.25×105个/cm3,具有理想的发泡效果。
The calcium carbonate whisker was modified by silane coupling agent,which was added into polypropylene with different content. Microcellular foam polypropylene/calcium carbonate whisker composites was prepared by twice-open mold. The effects of different contents of calcium carbonate whisker on foaming behavior were analyzed in microcellular foam composite. The results showed that the content of calcium carbonate whisker was 10 % , the size dispersion was 6.25, cell diameter was 25. 27 μm, cell density was 4. 25 × 10^5 months/cm^3, there was ideal foaming effect in microcellular foam composite.
