Abstract
本发明公开了一种用于木门喷涂的抗静电粉末涂料。由如下重量份数的组分构成：高分子树脂50‑80份、导电剂3‑10份、填料5‑15份、流平剂1‑3份、固化剂3‑5份、分散剂3‑5份、偶联剂3‑5份。本发明的粉末涂料，采用聚甲基丙烯酸正丁酯和非晶态α‑烯烃共聚物作为主料制备而成，加入导电剂，材料的附着力强，耐腐蚀性能好，同时具有较高的抗静电性能，适合于木门喷涂。
Description
技术领域
本发明属于粉末涂料技术领域，具体涉及一种用于木门喷涂的抗静电粉末涂料。
背景技术
粉末涂料是以固体树脂和填料及助剂等组成的固体粉末状合成树脂涂料。和普通溶剂型涂料及水性涂料不同，它的分散介质不是溶剂和水，而是空气。它具有无溶剂污染，能耗低的特点。粉末涂料有热塑性和热固性两大类。热塑性粉末涂料是由热塑性树脂、颜料、填料、增塑剂和稳定剂等成分组成的，热塑性粉末涂料包括：聚乙烯、聚丙烯、聚酯、聚氯乙烯、氯化聚醚、聚酰胺系、纤维素系、聚酯系等。热固性粉末涂料是以热固性合成树脂为成膜物质，在烘干过程中树脂先熔融，再经化学交联后固化成平整坚硬的涂膜。
传统使用油漆喷涂木门，需要大量液态溶剂作为稀释剂，这种溶剂会在生产和使用中释放大量VOCs；VOCs是形成PM2.5和臭氧的关键前体物，是复合型大气污染的重要诱因。粉末喷涂是完全符合国家环保法要求的一种喷涂方法，具有零污染、低成本等特点，在环境保护法规的促进下，限制VOC的排放量将使粉末喷涂得到更快的推广应用，带来的经济效益前景非常可观，但是粉末喷涂的涂料常常产生大量静电，限制了其广泛应用。
