水性带锈涂料的现状与发展

Actuality and Development of Waterborne Coatings for Rusty Iron and Steel Surface

水性带锈涂料的分类:按成膜树脂分为醇酸类、环氧类、油性酚醛类、环氧-煤焦油、环氧-聚乙烯醇缩丁醛类等;按抗锈作用原理分为渗透型、转化型和稳定型三种;阐述了制取水性成膜物质的主要途径和各类涂料的发展以及优缺点。较为系统地介绍了醇酸类、丙烯酸酯类、聚氨酯-丙烯酸酯共聚树脂并介绍了水性防腐涂料用乳胶液的研究进展概况及水性带锈涂料的作用原理,对封闭锈层的方法、铁锈的转化和稳定过程以及水性带锈涂料有待解决的问题均作了详细阐述。

According to the types of film forming resin, waterborne coatings for rusty iron and steel surface can be classified as alcohol - acid, epoxy, oleeresin, epoxy - coal tar, epoxy - polyvinyl butyral and etc, and according to anti - rust theory, they can be classified as pervasion, transformation and stabilization. The technology of preparing waterborne film forming substance and development, advantage and disadvantage of several coatings are introduced. The alcohol - acid, acrylate, and polyurethanes - acrylate copolymer resin paint, and development of latex for waterborne anti - corrosive paint, and the mechanism of waterborne coatings for rusted surface are presented. The methods of dernsting, process of transformation and stabilization of rust, and the unsolved prnblems about waterborne coating for rusty iron are detailed.
