一种绝缘胶带及其制备方法
技术领域
本发明涉及胶带技术领域，具体涉及一种绝缘胶带及其制备方法。
背景技术
胶带按他的功效可分为：高温胶带、双面胶带、绝缘胶带、特种胶带、压敏胶带、模切胶带，不同的功效适合不同的行业需求。胶带表面上涂有一层粘着剂，才能令胶带粘住物品，最早的粘着剂来自动物和植物，在十九世纪，橡胶是粘着剂的主要成份；而现代则广泛使用各种聚合物。绝缘胶带专指电工使用的用于防止漏电，起绝缘作用的胶带。又称绝缘胶布，胶布带，由基带和压敏胶层组成。基带一般采用棉布、合成纤维织物和塑料薄膜等，胶层由橡胶加增黏树脂等配合剂制成，黏性好，绝缘性能优良。绝缘胶带具有良好的绝缘耐压、阻燃、耐候等特性，适用于电线接驳、电气绝缘、隔热防护等特点。
绝缘胶带一般由基带和压敏胶层组成。基带一般采用棉布、合成纤维织物和塑料薄膜等，胶层由橡胶加增黏树脂等配合剂制成，黏性好，绝缘性能优良。
目前的绝缘胶带除了要有绝缘的效果，还需要有耐热、防腐蚀的效果。传统的绝缘胶带主要采用沥青基胶粘剂，随着时间的流逝，粘剂的粘结强度逐渐降低，耐久性较差，绝缘胶带在阳光下长时间的暴晒，或者被海水、河水的侵蚀，容易老化而失去绝缘的功能，绝缘胶带寿命低对使用者会造成严重的影响。
