Problems solved by technology

Chlorine-containing polymer refers to a resin containing a large amount of chlorine in its composition, which has excellent anti-corrosion properties. At present, the most widely used chlorine-containing polymer in my country is chlorinated rubber, but its application is limited by solubility, miscibility and environmental protection. However, other resins also have various characteristics of poor weather resistance and poor chemical corrosion resistance to varying degrees.

Abstract

The present invention provides an acrylic acid grafted modified chlorinated polyether resin emulsion anticorrosion coating material, which is prepared from the following components by weight: 60-70% of an acrylic acid grafted modified chlorinated polyether resin emulsion, 5-7% of zinc phosphate, 10-15% of composite iron titanium powder, 5-10% of talc powder, 3-6% of titanium dioxide, 0.1-0.5% of an anti-foaming agent, 0.5-1.0% of a dispersant, and 0.5-1.0% of a thickener, wherein the acrylic acid grafted modified chlorinated polyether resin emulsion is prepared from the following components by weight: 10-20% of chlorinated polyether resin, 0-30% of propylene glycol butyl ester, 1-3% of butyl methacrylate, 3-5% of ethyl acrylate, 4-7% of methyl methacrylate, 2-5% of 2-ethylhexyl acrylate, 0.1-1% of benzoyl peroxide, and the balance of deionized water. According to the present invention, the coating material contains the copolymerized vinyl chloride ether so as to provide good adhesion, such that the disadvantages of other chlorine-containing polymer resins are basically solved.

Description

technical field [0001] The invention relates to an anti-corrosion material, in particular to an acrylic acid graft modified chlorine ether resin emulsion anti-corrosion coating and a preparation method thereof. Background technique [0002] At present, heavy-duty anti-corrosion coatings mainly include the following varieties: organic fluorine coatings, epoxy anti-corrosion coatings, chlorine-containing anti-corrosion coatings, polyurethane coatings, etc. Chlorine-containing polymer refers to a resin containing a large amount of chlorine in its composition, which has excellent anti-corrosion properties. At present, the most widely used chlorine-containing polymer in my country is chlorinated rubber, but its application is limited by solubility, miscibility and environmental protection. However, other resins also have various characteristics of poor weather resistance and poor chemical corrosion resistance to varying degrees. Contents of the invention [0003] The object of ...
