Two-component epoxy organic anticorrosive paint and preparing method and using method thereof

Abstract

The invention discloses two-component epoxy organic anticorrosive paint. The paint comprises a component A and a component B; the component A is prepared from, by weight, 33-43 parts of epoxy organic silicon resin, 27-35 parts of epoxy resin, 4-7 parts of glass flake, 13-17 parts of pigment, 4-7 parts of filler, 1.3-2.2 parts of auxiliary and 2-4 parts of diluents; the component B is prepared from, by weight, 35-50 parts of polyamide curing agent, 13-17 parts of pigment, 4-7 parts of filler, 0.7-1.2 parts of anti-settling agent and 40-60 parts of solvent. The two-component epoxy organic anticorrosive paint the advantages that it is indicated through the comprehensive detection results of the paint that all physicochemical indexes reach the industrial standard, and a coating is tough, large in adhesive force, high in mechanical strength and long in anticorrosion life. The paint has good corrosion resistance, and it is proved through detection that salt mist resisting time reaches 4000 h, the paint does not bubble or rust. As the coating contains the glass flake with high pigment volume concentration, the glass flake is arrayed in the coating in an alternately overlapping mode to form a labyrinth effect, and the coating is excellent in shielding performance and impermeability and is resistant to permeation and corrosion of a corrosive medium.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a two-component epoxy organic anticorrosion coating and a preparation method and application method thereof. Background technique [0002] With the continuous development of the national economy and basic construction, the requirements for anti-corrosion of national key projects and large-scale projects are getting higher and higher. Large-scale steel equipment, components, and pipelines put forward higher requirements for coatings, that is, coatings are required to have excellent corrosion resistance. Rust and corrosion resistance, but also must have good construction, adaptability and durability. However, the traditional epoxy anti-rust paint has high requirements on the surface treatment of steel structures. When the project that has already been in operation needs to be repaired and painted, a second high-quality rust removal treatment must be carried out, and it...

Problems solved by technology

However, the traditional epoxy anti-rust paint has high requirements on the surface treatment of steel structures. When the project that has already been in operation needs to be repaired and painted, a second high-quality rust removal treatment must be carried out, and it must be repaired and repaired every few years. Apply the paint once to prevent rust and corrosion of steel
