摘要：以 α,ω-二羟基聚二甲基硅氧烷、α,ω-二乙烯基聚二甲基硅氧烷、含氢硅油、空心玻璃微珠（HGB）为
原料，采用室温硫化法制备了一系列不同 HGB 用量的硅橡胶泡沫（SF）/HGB 复合材料，并研究了 HGB
用量对 SF/HGB 复合材料的交联密度、泡孔结构、机械性能、动态力学性能的影响。结果表明：HGB 质量
分数为 6.0%时制备的 SF/HGB6 复合材料具有最佳的综合性能。并考察了 SF/HGB6 复合材料的静态缓冲性
能和动态疲劳性能。结果表明：SF/HGB6 复合材料的缓冲系数与聚乙烯泡沫（EPE）非常接近；该复合材
料具有较长的疲劳寿命（600 万次）和较高的高度保持率（98.4%），远高于 EPE（29 万次，54.5%）；并且
SF/HGB6 复合材料的缓冲系数在疲劳实验前后几乎没有变化，明显优于传统的缓冲材料 EPE，可作为包装
领域的缓冲材料。

Abstract: A series of silicone rubber foam (SF)/hollow glass beads (HGB) composites were prepared by
room temperature vulcanization method using α,ω-dihydroxy polydimethylsiloxane, α,ω-divinyl
polydimethylsiloxane, hydrogen silicone oil and HGB as raw materials. The effects of HGB dosage on the
crosslinking density, cellular structure, mechanical properties, and dynamic mechanical properties of
SF/HGB composites were studied. The results indicated that SF/HGB6 composite containing 6.0% HGB
(mass fraction) had the best comprehensive performance. Furthermore, the static cushioning and dynamic
fatigue properties of SF/HGB6 composite were investigated. It was found that the cushioning coefficient of
SF/HGB6 composite was very close to that of polyethylene foam (EPE). SF/HGB6 composite exhibited
long fatigue life (6 million times) and high height retention rate (98.4%), far greater than those of EPE (0.29
million times, 54.5%). Moreover, the cushioning coefficient of SF/HGB6 composite had little change
before and after fatigue test, which was obviously superior to that of traditional cushioning material EPE.
Therefore, SF/HGB6 composite can be used as a cushioning material in the packaging field.
