Abstract

The invention discloses an anticorrosive paint composition containing a self-emulsifying curing agent. The anticorrosive paint composition is prepared from a component A and a component B according to the mass ratio that A:B=(5-10):1. The component A is prepared from, by mass, 5% to 15% of water-based epoxy ester resin, 10% to 30% of chloroethylene-vinyl acetate-butyl acrylate resin, 10% to 15% of chloroethylene-vinyl acetate resin, 15% to 20% of mica, 15% to 20% of talcum powder, 5% to 8% of antifoaming agent, 9% to 12% of emulgator and 10% to 15% of deionized water. The component B is prepared from, by mass, 5% to 16% of self-emulsifying curing agent, 15% to 20% of triethylene diamine, 15% to 20% of diethylenetriamine, 10% to 15% of sodium nitrite, 25% to 32% of zinc phosphate and 10% to 20% of deionized water. The paint has the advantages that good abrasion resistance and corrosion resistance are achieved, the raw materials are easy to obtain, and price is low. The invention further discloses a preparation of the anticorrosive paint composition containing the self-emulsifying curing agent.

Description

technical field [0001] The invention belongs to the field of chemical materials, and in particular relates to an anti-corrosion coating composition containing a self-emulsifying curing agent and a preparation method thereof. Background technique [0002] Epoxy resin is an important anti-corrosion material with high viscosity. In order to improve the construction performance, it needs to add solvent or active diluent when using it. However, these substances are easy to diffuse into the air and cause pollution to the environment. In order to change this situation, people propose to carry out water-based treatment of epoxy resin, so as to solve the environmental pollution problem generated during the use of epoxy resin coatings. [0003] At this stage, there are two basic ideas for the preparation of waterborne epoxy resins: water emulsion type and water dilution type. The former relies on the emulsifier to prepare the epoxy resin into an emulsion first, and then prepares the ...
