一种涂覆硅胶树脂的硅橡胶表带
本技术涉及硅橡胶表带的涂层领域,具体地,涉及一种涂覆硅胶树脂的硅橡胶表带。
技术介绍
硅胶手表具备耐黄变、不变形、无毒、无味,对人体无副作用等特点和柔软、不开裂、使用寿命长、不刺激皮肤等优点。但硅胶本身手感发涩,耐磨性能不好,尤其是在一些色泽比较鲜艳的基材上面,非常容易刮花。目前,国内常规的做法是在硅胶表带表面涂覆聚氨酯手感漆,以弥补硅胶的一些缺陷,如:耐磨性、手感爽滑性等;但聚氨酯手感漆耐温性远远低于硅胶本身的耐温性,而且聚氨酯漆在一段时间后,容易发黄而影响了表带的美观性能,更重要的是聚氨酯手感漆中都有添加有机锡作为催化剂,这对紧贴皮肤的产品来说,带来较大的人体安全问题。聚四氟乙烯(Teflon或PTFE),俗称“塑料王”,是由四氟乙烯经聚合而成的高分子化合物,具有优良的化学稳定性、耐腐蚀性、密封性、高润滑不粘性、电绝缘性和良好的抗老化耐力。用作工程塑料,可制成聚四氟乙烯管、棒、带、板、薄膜等。本专利所需要解决的问题就是用硅胶树脂的涂层来替换硅胶表带表面的聚氨酯涂层,在不降低耐磨性能的前提下,提高手感涂层的耐高温性,耐黄变性以及与皮肤的亲和性。
技术实现思路
针对现有技术中的缺陷,本技术的目的是提供一种涂覆硅胶树脂的硅橡胶表带,通过在硅胶表带上涂覆含PTFE的硅胶树脂涂层,可最大化的体现硅胶基材的各种优越性,同时提高了硅胶基材表面的爽滑性与耐磨性,并解决了聚氨酯手感漆中的因添加有机锡助剂而带来的安全与环保问题;其长效的耐黄变性、触感柔性、耐汗性以 ...
