Description

一种顺丁橡胶微孔发泡材料及其制备方法
技术领域
本发明属于高分子材料领域，具体涉及一种顺丁橡胶微孔发泡材料及其制备方法。
背景技术
顺丁橡胶即顺式-1,4-聚丁二烯橡胶，简称BR，是由丁二烯聚合制得的结构规整的合成橡胶。与天然橡胶和丁苯橡胶相比，硫化后的BR的耐寒性、耐磨性和弹性特别优异，动负荷下发热少，耐老化性尚好，易与天然橡胶、氯丁橡胶或丁腈橡胶并用。
BR特别适于制汽车轮胎和耐寒制品，还可以制造缓冲材料以及各种胶鞋、胶布、胶带、密封圈、鞋底及电缆等橡胶制品和海绵胶等。
目前对顺丁橡胶发泡材料的研究基本上是和其他材料共混发泡得到发泡材料，而对单纯顺丁橡胶的发泡材料研究较少。已经有文献报道，可以运用化学发泡剂AC制备LDPE/BR橡塑混合微孔复合材料，得到具有较好综合机械性能的发泡材料；其具有质轻、柔韧、弹性好、尺寸稳定等特点；此材料应用较为广泛，如汽车密封窗条、冰箱密封窗条、铝合金窗密封条、隔音阻尼材料、装饰材料以及包装保温材料，尤其是作为鞋用新材料发展较快。另外，还有BR/LLDPE微孔发泡材料，可提高材料的拉伸强度和密度等物理机械性能；还具有密度低、泡孔小、弹性较好等特点；可扩展发泡橡胶在对拉伸强度、撕裂强度要求高的方面的应用。
发明内容
