Abstract

The invention discloses a delayed double-component water-based anticorrosive paint matching system, which comprises a delayed double-component water-based epoxy primer, a delayed double-component water-based epoxy intermediate paint and a delayed double-component water-based polyurethane finish paint which are distributed from bottom to surface, and each of the delayed double-component water-based epoxy primer, the delayed double-component water-based epoxy intermediate paint and the delayed double-component water-based polyurethane finish paint comprises a main agent and a curing agent; the main agents of the delay type double-component waterborne epoxy primer and the delay type double-component waterborne epoxy intermediate paint comprise water, a base material wetting agent, a coalescing agent, a defoaming agent, a dispersing agent, an anti-settling agent, waterborne resin, a flatting agent and a thickening agent, and the curing agent comprises a waterborne polyamide curing agent, an anti-flash-rust agent and water; the delayed bi-component waterborne polyurethane finish paint comprises water, a base material wetting agent, a cosolvent, an amine neutralizer, a defoaming agent, a dispersing agent, an anti-settling agent, waterborne resin, a flatting agent and a thickening agent, and the curing agent comprises a waterborne polyurethane curing agent and a solvent. According to the present invention, the construction validity period can be prolonged, the surface dryness, the hard dryness, the adhesion, the impact, the flexibility and the sagging performance are excellent, and the chemical resistance is substantially unchanged.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a time-delayed two-component water-based anti-corrosion coating supporting system. Background technique [0002] In the field of industrial anti-corrosion coatings, the more commonly used coating systems under chemical and marine environmental conditions usually use two-component epoxy primers from bottom to surface, matching two-component epoxy intermediate paints and then two-component polyurethane topcoats , through different film thicknesses to protect steel from corrosion under various environmental temperature factors. As a protective coating for steel substrates, two-component coatings have excellent physical, mechanical and chemical resistance properties unmatched by single-component coatings, and are generally used in chemical marine environments of C3 or above. However, as a two-component coating, it must be mixed and stirred on site during use, and the mix...
