纳米SiO2对微发泡聚丙烯复合材料发泡行为的影响
Effect of Nano-SiO2 on Foaming Behavior of Microcellular Foam Polypropylene Composites
摘要
Abstract
The different content modified nano-SiO2 was added into polypropylene. The microcellular foam PP/nano-SiO2 composites were made under the twice-mold-opening condition. The effect of different content of nano-SiO2 on foaming behavior of composites was analyzed. The results show that with the increase of nano-SiO2 content, the cell diameter decreases gradually, and the cell density increases gradually. The cell diameter is 16.3 μm and cell density is 1.41 × 109cell/cm3, when the content of nano-SiO2 is 4％. There is an ideal foaming effect in microcellular foam composites.关键词
