摘要： 采用机械共混法制备了硅橡胶/氯化聚乙烯泡沫合金材料，研究了硅橡胶/氯化聚乙烯共混胶相容性及热处理时间对泡沫合金材料密度、泡孔结构及阻尼性能的影响。结果表明，硅橡胶/氯化聚乙烯共混胶具有较好的相容性；与实心共混胶相比，泡沫合金材料的阻尼性能显著提高，损耗因子从0.43提高到0.68，损耗因子大于0.3的有效阻尼温域从16 ℃拓宽到45 ℃，玻璃化转变温度向高温偏移了13 ℃左右；当受到热处理之后，泡沫合金材料的阻尼性能降低。

Abstract: The foams of silicone rubber/CPE blends were prepared via mechanical blending methods. The compatibility of the components, influence of heat treatment time on density, foam structure and damping properties were investigated. The blends of silicone rubber/CPE showed a good compatibility. Compared with neat silicone rubber, the effective damping temperature range (tanδ＞0.3) was broadened from 16℃ to 45℃, the maximum loss factor was increased from 0.43 to 0.68, and the glass transition temperature increased by 13℃. However, the damping properties of the foams were damaged by heat treatment.

Key words: silicone rubber, chlorinated polyethylene, foam, damping property
