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.
