Abstract

The present invention relates to one kind of water soluble acrylic acid modified antirust epoxy resin paint. The modified antirust epoxy resin paint includes water soluble acrylic acid modified epoxy resin 45.0-62.0 wt%, water soluble amino resin 3.0-6.0 wt%, coloring pigment 5.0-15.0 wt%, antirust pigment 6.0-10.0 wt% and stuffing 5.0-10.0 wt%, and it contains also neutralizing agent, co-solvent, dispersant, defoaming agent, thickener, corrosion inhibitor, drying promoter and deionized water. The modified antirust epoxy resin paint contains no organic solvent and harmful lead and chromium compound, has no hazard of burning, explosion, poisoning and polluting environment, and has excellent protecting performance and decoration effect.

Description

technical field [0001] The invention belongs to the technical field of paints, and in particular relates to a water-soluble anti-corrosion coating mainly used for iron and steel products, especially suitable for the protective and decorative coating of traffic vehicles, engineering machinery, household appliances and steel furniture manufacturing industries, etc. Acrylic modified epoxy ester antirust paint. Background technique [0002] Traditional antirust paints are mostly solvent-based paints, which contain harmful organic solvents such as benzene, pollute the air and damage human health. At the same time, most of these paint products contain lead and chromium pigments, which will also cause environmental pollution and endanger human health. In recent years, some varieties of water-based anti-rust paints have also appeared. There are mainly two types, namely latex type and water-soluble type. The former has poor storage stability and unsatisfactory anti-rust performance...
