Corrosion-resistant high-adhesive-force water-based metal paint

Abstract

The invention discloses a corrosion-resistant high-adhesive-force water-based metal paint which is prepared from the following raw materials in parts by weight: 20-30 parts of polyorthotoluene glycidol ether, 15-20 parts of bisphenol F epoxy resin, 10-20 parts of polyphenyl glycidyl ether, 20-30 parts of silica sol, 1-3 parts of iron oxide red, 1-2 parts of titanium white, 12-16 parts of mica powder, 15-30 parts of modified wollastonite, 2-6 parts of quartz powder, 1-3 parts of silicon oxide, 1-2 parts of zinc oxide, 5-10 parts of ground calcium carbonate, 1-3 parts of aluminum tripolyphosphate, 5-10 parts of zinc phosphate, 0.2-0.8 part of antimicrobial agent, 1-2 parts of mildew preventive, 1.5-3 parts of leveling agent, 1-2 parts of defoaming agent, 1-2 parts of wetting agent, 1-3 parts of dispersing agent, 2-6 parts of ethylene glycol, 20-30 parts of water and 2-5 parts of film-forming assistant. The metal paint has the advantages of favorable corrosion resistance, high adhesive force and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a corrosion-resistant high-adhesion water-based metal coating. Background technique [0002] At present, most metal coatings contain organic solvents, which are very easy to volatilize during the coating process, seriously polluting the atmosphere and destroying the ecological environment. Nowadays, more and more attention is paid to environmental protection. Water-based metal coatings will replace traditional solvent-based coatings and will become The mainstream of anti-corrosion coatings in the future, water-based epoxy coatings have good adhesion to metals and low shrinkage, but in general, there is still a considerable gap between the anti-corrosion performance and adhesion of water-based metal coatings and oil-based epoxy coatings. How to prepare a kind of anti-corrosion performance Well, water-based epoxy coatings with strong adhesion have become a technical problem that n...
