磷酸酯功能单体改性水溶性丙烯酸树脂合成及其防腐蚀性能

Synthesis and Anti-corrosion Properties of Water-soluble Acrylic Resin Modified by Phosphate Functional Monomer

通过溶液聚合法合成了一种含磷酸酯基团的水溶性丙烯酸树脂。制备了水性丙烯酸树脂涂料和涂层。在成膜过程中,磷酸酯基团能与底材金属形成致密的磷酸盐保护层,同时羟基与氨基交联固化,在金属表面形成屏蔽层,从而提高了金属的防腐蚀性能。

A water-soluble acrylic resin containing phosphate was prepared by solution polymerization and used in anti-corrosion coating. In the process of film-forming, the phosphate groups were bonded on substrate metal to form a compact protection film, which could prevent water and other salt ions to contact with metal, thus improv the anticorrosion property of coatings.
