水性环氧防腐底漆以水为主要溶剂和稀释剂,与使用挥发性有机溶剂的油性环氧防腐底漆大相径庭。水在水性环氧防腐涂层中的渗透性对漆膜的性能特别是湿附着力、防腐蚀性能具有很大的影响,因此此项研究为如何提高水性环氧防腐涂层性能提供了非常重要的改善途径。本文研究了水性环氧防腐底漆涂膜的吸水率和吸水量对水性环氧防腐涂层的湿附着力、防腐蚀性和光泽的影响。

The waterborne epoxy anti-corrosive primer is quite different from the oil-based epoxy anti-corrosive primer which uses volatile organic solvents because water is used as the main solvent and diluent in the former.The permeability of water in the waterborne epoxy anti-corrosive coating has a impact on the performance of the coating film,especially on the wet adhesion and anti-corrosion properties.Therefore,this study provides a very important improvement approach how to enhance the performance of waterborne epoxy anti-corrosive coatings.This paper studies the effects of water absorption rate and water absorption amount of waterborne epoxy-corrosive primer coating film on the wet adhesion,anti-corrosion and gloss of the waterborne epoxy anti-corrosive coating.
