摘　　要：水性涂料是绿色环保涂装的主要方向,涂层湿附着力测试是决定涂层防腐蚀性能最有效率的指标。本文概述了湿附着力作用机制,试验了不同成膜水性树脂种类、不同水性环氧、颜基比以及微纳米水滑石改性对涂层湿附着力、吸水率以及耐盐雾性能的影响。It is a typical development trend that waterborne coatings are used for the environmental friendly coating process. The wet adhesion is an important parameter to determine the anticorrosive performance of coatings. This paper describes the principle of wet adhesion mechanism. Meanwhile, the effects of film-forming materials, waterborne epoxy resin, pigment/binder ratio and micro-nano hydrotalcite modification on wet adhesion, water absorption and salt fog resistance of coating are investigated.
