Description

一种防静电自清洁金属涂料及其在电力设备的应用
技术领域
本发明涉及涂料领域，具体为一种防静电自清洁金属涂料及其在电力设备的应用。
背景技术
涂料，在中国传统名称为油漆。所谓涂料是涂覆在被保护或被装饰的物体表面，并能与被涂物形成牢固附着的连续薄膜，通常是以树脂、或油、或乳液为主，添加或不添加颜料、填料，添加相应助剂，用有机溶剂或水配制而成的粘稠液体。金属材质的产品一般都需要进行表面处理，改变自身特性，方便使用。
中国专利库中公开了一种抗静电涂料(CN201210192853.0)，其特征在于，所述涂料按重量份数包括：E-12环氧树脂：20～40、聚酯树脂：20～40、有机硅树脂：6～25、颜料：2～15、抗静电剂：1～20。所述抗静电涂料在保证涂料的抗静电性能的同时，所述涂料的附着力、耐候性、耐磨性、以及耐高温性能等性能均十分优异。
中国专利库中公开了一种水性抗静电涂料(CN201210178892.5)。所述涂料由导电填料和成膜物质构成；所述导电填料由片状锌粉和铜粉组成，所述成膜物质为2,4-甲苯二异氰酸酯交联改性聚乙烯醇。所述2,4-甲苯二异氰酸酯改性聚乙烯醇通过下列方法制备得到：23～85℃下在聚乙烯醇水溶液中加入2,4-甲苯二异氰酸醋，反应至少1小时，即得到2,4-甲苯二异氰酸酯改性聚乙烯醇水溶液。本发明采用片状锌粉和铜粉作为导电填料，具有优良的导电性性能。本发明具有良好的附着力、优良的物理机械性能、耐有机溶剂、耐腐蚀、较好的耐水性能以及良好的稳定性。
很多电力设备特别是室外设备都采用金属外壳包裹，金属外壳使用时间长了，容易积存污垢、影响设备的导电性，导电性能下降，在雨雪天容易引起电击，对设备造成损害。
