Abstract

The invention discloses an anti-corrosion coating composition containing a self-emulsifying curing agent, which is composed of A component and B component in a mass ratio of A:B=(5-10):1, wherein the A component is in mass percentage 5-15% of water-based epoxy resin, 10-30% of vinyl chloride-vinyl acetate-butyl acrylate resin, 10-15% of vinyl chloride-vinyl acetate resin, 15-20% of mica, talc Powder is 15‑20%, defoamer is 5‑8%, emulsifier is 9‑12%, deionized water is 10‑15%; B component is composed of self-emulsifying curing agent in mass percentage of 5‑16% %, triethylenediamine is 15‑20%, diethylenetriamine is 15‑20%, sodium nitrite is 10‑15%, zinc phosphate is 25‑32%, and deionized water is 10‑20%. The coating of the invention has the characteristics of good wear resistance and corrosion resistance, and the advantages of easy availability of raw materials and low price. The invention also discloses a preparation method of the anticorrosion coating 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 ...
