3A分子筛填充硅橡胶发泡材料性能研究

Study on 3A Molecular Sieve Filled Silicone Rubber Foam Composites of Properties

研究加入不同量3A分子筛对硅橡胶泡沫材料的拉伸强度、断裂伸长率、密度、硬度、压缩永久变形、吸湿率性能的影响.结果表明:随着3A分子筛加入量的增加,拉伸强度、压缩永久变形、密度、硬度、吸湿率随之增加,断裂伸长率随之降低;泡孔尺寸变小,均匀性变好.

The influence of 3A molecular sieve on the performance of silicone rubber foam is studied in this paper. The results were shown that tensile strength, compression permanent deformation, density, hard- ness, moisture absorption rate was increased with the 3A molecular sieve content, the breaking elongation was decreased, and foam hole dimension uniformity was better.
