摘要
采用刚性无机粒子（ＳＩＯ２）填充不相容聚二甲基硅氧烷／聚氨酯（ＰＤＭＳ／ＰＵ）共混体系．重点研究了ＳｉＯ２表面处理剂种类、ＳｉＯ２填充量对不同结构的ＰＤＭＳ／ＰＵ共混体系力学性能的影响关系．研究结果表明：ＳｉＯ２经过适当偶联剂表面处理后，能显著地提高ＰＤＭＳ／ＰＵ（Ｍ）、ＰＤＭＳ／ＰＵ（Ｐ）共混物的力学性能，其抗张强度分别由３．４ＭＰａ、４．５ＭＰａ提高到１２．３ＭＰａ和９．０ＭＰａ．
Inorganic particles were mixed with imcompatible polydimethylsiiloxane/polyurethane(PDMS/PU)blends and the effects of coupling agents and the fraction of filler on the mechanical properties of PDMS/PU)blends were investigated.The results showed a great improvement of mechanical prperties when PDMS/PU blends were filled with silica treated with certain coupling agent.
