摘要:
以乙烯-乙酸乙烯酯-甲基丙烯酸缩水甘油酯橡胶为基体、γ-氨丙基三乙氧基硅烷为接枝单体、偶氮二甲酰胺为发泡剂,通过水交联与过氧化物交联相结合的方式制备了双交联发泡材料,并使用扫描电子显微镜、动态力学性能频谱仪和电子万能试验机等对发泡材料的泡孔形貌、动态力学性能和物理机械性能等进行了考察。结果表明,双交联发泡工艺得以实现,经过水交联后所形成的交联网络有效提高了泡孔尺寸的均匀性及分散性;当过氧化二异丙苯的用量为0.25份(质量)时,双交联发泡材料具有最窄的泡孔尺寸分布,发泡效果最佳,具有较好的吸能效果,适用于制备阻尼材料。
Abstract:
With ethylene-vinyl acetate-glycidyl methacrylate (EVM-GMA) rubber as matrix, γ-aminopropyltriethoxysilane (APTES) as grafting monomer and azodicarbonamide as foaming agent, double crosslinked foaming materials were prepared by combination of water crosslinking and peroxide crosslinking. The cell morphology, dynamic mecha-nical properties, and physical and mechanical properties of the foaming materials were investigated by scanning electron microscopy, dynamic mechanical property spectrometer and electronic universal tes-ting machine. The results showed that the double crosslinked foaming process could be realized, and the crosslinking network formed by water crosslin-king could effectively improve the uniformity and dispersion of cell size. When the amount of dicumyl peroxide was 0.25 phr (mass), the double crosslinked foam material had the narrowest cell size distribution, the best foaming effect, and better energy absorption effect, which was suitable for application of damping materials.
