Description
技术领域
本发明涉及橡胶树脂层积体。更详细地说，涉及通过将含有马来酰亚胺化合物、受酸剂、硫化剂的未硫化环氧氯丙烷类橡胶组合物层与热可塑性树脂层加热并粘合从而两层被牢固粘合的硫化橡胶层积体。
背景技术
近年，以美国为中心，对来自汽车燃料系统的烃类蒸腾气体的限制变得非常严格，与此相应的各种结构的燃料系统橡胶管的开发正在进行之中。尤其是，为了确保耐燃料透过性、柔软性等，已设计使用有对阻挡层配置燃料阻隔性树脂，并在其上作为内层及/或外层层积了橡胶材料的各种橡胶管。
普遍是，例如，将氟树脂用于阻挡层并在内层及/或外层层积了氟橡胶(FKM)、环氧氯丙烷橡胶(ECO)、丙烯腈-丁二烯橡胶(NBR)、氯磺化聚乙烯(CSM)、氯化聚乙烯等的结构的管(hoos)。
根据专利文献1公开的内容，在氟树脂和环氧氯丙烷类橡胶的橡胶层积体上，作为环氧氯丙烷类橡胶组合物，通过混合特定的粘合赋予剂来改善粘合性。然而，上述这样的氟树脂-橡胶层积管，阻挡层的氟树脂价格非常高，并且，如果要提高燃料透过性，还需要增加阻挡层的厚度、或增加氟含量，因此，用这种方法，会出现管本身变硬，加工变难等不良情况。
因此，提出了各种使用氟树脂以外的耐燃料透过性优良的树脂来形成阻挡层的方法，在专利文献2、3、4中，公开了使用燃料阻隔性优良的热可塑性树脂的多层管结构，在专利文献4中公开了使燃料阻隔性优良的热可塑性树脂层与橡胶层粘合的方法。
然而，众所周知，高分子的不同种类材料之间普遍缺乏粘合性，在上述这样的多层管的情况下，这些不同种类材料的粘合性是最重要的课题，为了改善它们的粘结性，提出了各种方法，但若是燃料阻隔性优良的热可塑性树脂和环氧氯丙烷类橡胶，则无法获得充分的粘合力，为了牢固地粘合，需要混合大量的粘合剂，现状是达不到实用化，需要一种具有更高粘合性的橡胶热可塑性树脂层积体。
