塑料件用水性导电涂料的研制

Development of Waterborne Conductive Coatings for Plastic Electroplating

以水溶性丙烯酸树脂为基料、银包铜粉为导电填料，制备了一种水性导电涂料，并对其理化性能参数进行了测试。讨论了导电填料、水加入量、分散剂以及固化温度、涂膜厚度等对导电涂料性能的影响，确定了最佳的水性导电涂料组成和工艺条件：树脂用量22％、银包铜粉用量35％～44％、溶剂水的添加量28％-40％、分散剂用量0.62％左右、固化温度55℃。

Electrically conductive coatings, based on acrylic resin as binder and silver- plated copper powder as pigment has been prepared. The performance of the coating was tested. The influences of conductive pigments, amount of water, dispersant, curing temperature and film thickness on coatings performance was discussed. The optimal formulation of coatings and the technological conditions are： amount of resin 22%, silver -plated copper powder 35% ～44%, water 28% ～40%, dispersant 0. 62%, curing temperature 55℃.
