Description
技术领域
本发明涉及橡胶技术领域,具体涉及一种耐压、耐腐蚀橡胶气囊布复合材料及其制备方法。
背景技术
橡胶布是由橡胶涂层和基材(如织物)构成的复合材料制品,广泛用于防水、密封、保温、防护等领域,如CN103507341B公开了一种用于软管的橡胶布,其基础纤维布为芳纶纤维,外层橡胶为硅橡胶;CN101210389B提供了一种低发烟耐燃橡胶布的加工方法,其外层胶料为氯磺化橡胶,基础纤维布为聚酯布、尼龙布、棉布、尼龙/聚酯混纺纱布,填充氢氧化铝、硼酸锌;CN101209607A涉及一种未加硫再生丁基橡胶布及加工方法,其操作是将丁基再生橡胶加入三元乙丙,加白烟、煅烧土、防老剂混炼压延,与基布贴合,不用硫化,用于路面、房屋等的防水层铺垫;CN104441911A公开了一种消防用耐燃耐磨橡胶布的制备方法,聚酰胺纤维布作为基布,橡胶糊,氯磺化聚乙烯混炼胶片,压延贴合基布硫化成型。橡胶气囊布是特殊的橡胶布,其构成主要有基层纤维布(帘子布)及交联的橡胶层构成,纤维层作为橡胶气囊布的骨架起到支撑作用,交联的橡胶层同样具有优异的力学强度和气密性,因而采用橡胶气囊布可以制备可充气的制品,如管道封堵气囊、船用气囊、减震气囊、浇注用空芯构件、民用领域等。由于橡胶气囊布复合材料属于特殊的橡胶布,其技术要求和使用比普通的橡胶布要严格,因而产品种类和相关开发与通用橡胶布对比相对较少,国内从事橡胶气囊布复合材料开发的企业和单位远少于通用橡胶布。
CN102086637B,提供了一种高压无缝大型橡胶气囊及其生产工艺,其特点是采用EPDM橡胶做外胶,丁基橡胶做内胶,高强帘子线做基础纤维布,氯丁胶、天然胶作为中层胶;CN201711393967.0报道了一种高强度气囊布的生产方法,用于汽车的安全气囊,其方法是将PA66及其他交联剂、助剂通过熔融流延涂覆到汽车气囊上,形成高强度安全气囊布。
然而,专利申请CN102086637B中提供的高压无缝大型橡胶气囊,外层橡胶层为通用橡胶,橡胶力学性能一般,制品不耐油、不耐化学品腐蚀,形成制品的质量较低。
