Formula for preparing water-based epoxy paint

Abstract

The invention discloses a formula for preparing a water-based epoxy paint, which comprises the following components in parts by weight: 25-35 parts of water-based epoxy resin emulsion, 20-30 parts of nano silicon dioxide, 2-8 parts of aluminum tripolyphosphate, 3-9 parts of titanium dioxide, 5-15 parts of filler, 1-5 parts of curing agent, 2-6 parts of flash-rust inhibitor, 2-12 parts of defoaming agent, 4-10 parts of leveling agent, 3-8 parts of thickener and 30-40 parts of deionized water. The water-based epoxy paint is free of organic solvents and friendly to the environment, and can not damage the environment or human body. After the paint is brushed, the paint film has the advantages of high drying rate, low odor, high surface gloss, high binding force, excellent corrosion resistance and excellent wear resistance. The paint is suitable for the field of surface application of iron and steel, aluminum and other metals.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a formula for preparing water-based epoxy coatings. Background technique [0002] The molecular structure of epoxy resin contains a large number of benzene rings and ether bonds, the system strength is high, the molecular structure is compact, and the cohesive energy is large. Therefore, the coating prepared by epoxy resin has strong adhesion to the substrate, chemical medium resistance and anti-corrosion performance. Excellent, widely used in the field of heavy anti-corrosion. At present, most epoxy coatings are solvent-based, and the pollution is serious. Therefore, water-based epoxy resin coatings have become a research hotspot in various countries. [0003] However, after the water-based epoxy materials currently on the market are used in humid places, the paint film is not completely cured, causing the paint film to bulge, peeling, and the adhesion is seriously problematic. Moreover...

Problems solved by technology

At present, most epoxy coatings are solvent-based, and the pollution is serious, so water-based epoxy resin coatings have become a hot research topic in various countries.

[0003] However, after the water-based epoxy materials on the market are used in humid places, the paint film is not completely cured, causing the paint film to bulge, peeling, and the adhesion is seriously problematic. Moreover, the paint film has no gloss and poor wear resistance.
