摘　　要：在室温硫化型有机硅橡胶中加入聚合物中空微球制备室温硫化型有机硅复合泡沫材料。研究结果表明,固化条件(时间、温度)与硅橡胶一致;中空微球的含量越高,有机硅复合泡沫材料的成型工艺要求越高,当聚合物中空微球与硅橡胶的质量配合比达7∶10以上,需要外力的作用才可形成厚度均匀、表面平整的平面制件。中空微球与615胶的质量配合比为7∶10,固化时间约10h,制得的有机硅复合泡沫材料胶膜表面干爽,胶膜弹性好,压缩率达21.5%时,有机硅复合泡沫材料的泡孔结构仍具有较好的完整性和均匀性,能保持长期稳定的力学性能。The silicone composit foam was preparation by hollow polymer particles added to room temperature vulcanised polysiloxane rubbe.Although the time and temperature of silicone foam was the same as silicone rubber.the more hollow polymer particles of silicone foam,the higer its molding process.the external force was needed to form plane parts with uniform thickness and smooth surface,when mass ratio of hollow polymer particles and vulcanised polysiloxane rubber above 7∶10.The surface of rubber film feeled dry and elastic after vulcanised 10 hours when mass ratio of hollow polymer particles and vulcanised polysiloxane rubber 615 equal to 7∶10.The silicone foam had reliable mechanical performance as the integrity and homogeneity of its pores maintaining when compression equal to 21.5%.
