Abstract

The invention discloses a preservative resin coating. The preservative resin coating comprises the following components in percentage by weight: 60-80% of component A and 20-40% of component B, wherein the component A comprises the following components in parts by weight: 40-50 parts of polyester resin, 14-19 parts of epoxy resin, 8-12 parts of coloring pigments, 5-10 parts of rust-proof pigments, 5-7 parts of filler, 0.5-2 parts of auxiliary agents and 0.5-2 parts of a mixed solvent, the mixed solvent comprises xylene and butyl acetate, and the auxiliary agents include a defoaming agent, an anti-settling agent and a thixotropic agent; and the component B the following components in parts by weight: 0.5-1 part of plasticizer, 3-8 parts of tricarboxymethyl propane, 8-15 parts of butyl acetate, 15-25 parts of toluene diisocynate, 6-15 parts of xylene, 1-3 parts of cyclohexanone and 0.5-2 parts of polyurethane dehydrant. According to the preservative resin coating disclosed by the invention, the quality is stable, the polyester resin and the epoxy resin are taken as base materials to form an interpenetrating polymer network to endow the coating with compactness, the preservative property and the adhesive force are greatly improved, and the preservative resin coating cannot blister, rust, fade and fall in a long time.

Description

Technical field [0001] The invention relates to a coating, in particular to an anticorrosive resin coating. Background technique [0002] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings. They are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play a role in preventing corrosion of metals under general conditions and protect the service life of non-ferrous metals; heavy-duty anti-corrosion coatings are compared to conventional anti-corrosion coatings, which can be applied in relatively harsh corrosive environments and have performance A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] The existing coatings have poor corrosion resistance and adhesion stability, and are prone to blistering, rusting, fading and falling off. Summary of the invention [0004] Purpose of the invention: In order to overc...
