Abstract

The invention provides water-based anti-corrosion paint. The paint is prepared from the following components in parts by weight: 80-120 parts of epoxy acrylate, 0.1-8 parts of nano-silica subjected tosilane coupling agent surface treatment modification and 1-15 parts of curing agent, wherein the curing agent is selected from at least one of diisocyanate and triisocyanate, and the epoxy acrylate is synthesized by means of 1-6 parts by weight of epoxy butyrate, 30-50 parts by weight of methyl methacrylate, 30-50 parts by weight of butyl acrylate and 30-50 parts by weight of styrene. The mechanical performance, the water adsorption and the corrosion resistance of the paint are improved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based anticorrosion coating and a preparation method thereof. Background technique [0002] Waterborne epoxy acrylate has the characteristics of good water resistance, adhesion and high mechanical properties. Waterborne epoxy acrylate resins are widely used in the field of anti-corrosion coatings, but their internal hydrophilic groups help to form water permeation channels, which increase the water absorption of the coatings, resulting in reduced corrosion resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of prior art, provide a kind of water-based anticorrosion paint and preparation method thereof. [0004] In order to achieve the above object, the technical solution of the present invention is: a water-based anti-corrosion coating, the coating includes the following components by weight: [0005] 80-120 parts o...
