中文摘要:
      采用室温硫化法制备了一系列不同空心玻璃微珠(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用量为6%时对应的SF/HGB6复合材料具有最佳的综合性能。通过静态压缩试验考察了SF/HGB6复合材料的缓冲性能,其缓冲系数与聚乙烯泡沫(EPE)非常接近。动态压缩疲劳试验结果表明,SF/HGB6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试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。
英文摘要:
      A series of silicone rubber foam (SF)/hollow glass beads (HGB) composites were prepared by room temperature vulcanization. The effects of HGB content on the crosslinking density, cell structure, mechanical properties, dynamic thermomechanical properties of SF/HGB composites were studied. The results indicated that SF/HGB composite which prepared with 6.0 wt% HGB content had the optimal comprehensive performance. The cushioning properties of SF/HGB composites were investigated by the static compression test. The cushioning coefficient of SF/HGB composite was very close to polyethylene foam (EPE). Moreover, the fatigue properties of SF/HGB composites were investigated by the dynamic compressive fatigue test. SF/HGB composite exhibited long fatigue life (6.0 million times) and high height retention rate (98.4 %), which was far greater than those of EPE (0.29 million times, 54.5 %), and its cushioning coefficient was almost no changed before and after fatigue test, which was obviously superior to traditional cushioning materials EPE and could be used as a cushioning material in the packaging field.
