新型水性除锈防锈漆的研制

Preparation of a new-type aqueous rust-removing and anti-rusting paint

介绍了一种以聚醋酸乙烯酯乳液为基料、以磷酸为锈转化剂、以磷酸锌和铬酸锌为钝化剂和防腐剂的水乳型除锈、防锈漆的制备方法。该漆与同类溶剂型防锈漆相比，不仅具有除锈、防锈双重功能，而且成本低，无毒，无环境污染。

A process to prepare aqueous rust-removing and anti-corrosive paint by using polyvinyl acetate emulsion as adhesive,phosphoric acid as rust-transforming agent and zinc phosphate and zinc chromate as passivating agent and anticorrosive agent is introduced. As compared with that of solvent-type anti-corrosive paint,the new one has not only two functions of removing rust and anti-corrosion,but also lower cost,no poison and no pollution.
