Problems solved by technology

However, traditional solvent-based coatings contain more than 30% organic solvents. During the process of manufacturing, construction, drying, and curing of coatings, a large amount of VOC is released into the atmosphere, which constitutes extremely serious pollution and harm to the human ecological environment. threaten

Abstract

The invention belongs to the field of preparation of epoxy coatings and particularly relates to a solvent-free epoxy polyurethane resin floor coating. The coating is prepared from a component A and a component B. The component A comprises, by weight, 40-60 parts of dicyclohexylmethylmethane-4, 20-30 parts of glycerin, 1-5 parts of fumaric acid diethyl ester diisocyanate, 1-10 parts of p-tert-butyl phenyl glycidyl ether and 0.8-1.5 parts of p-toluenesulfonyl isocyanate. The component B is prepared from, by weight, 10-15 parts of epoxy resin, 0.5-1.0 part of stannous octoate, 0.1-0.8 part of cellulose acetate butyrate and 40-45 parts of quartz sand. The mass ratio of the component A to the component B is 4:1. The coating has the advantages that the coating is good in self-leveling performance, environmentally friendly, good in abrasion resistance, resistant to heavy load, excellent in chemical resistance, high in adhesive force, resistant to mould, easy and convenient to construct, easy to maintain and good in impact resistance, and elasticity can be adjusted according to site application.

Description

technical field [0001] The invention belongs to the field of preparation of epoxy coatings, in particular to a solvent-free epoxy polyurethane resin floor coating. Background technique [0002] Epoxy resin coatings have the advantages of strong anti-corrosion ability, strong adhesion, high hardness, wear resistance, salt spray resistance, acid and alkali resistance, high gloss, high solid content, and high fullness. Therefore, it is widely used as industrial heavy-duty anti-corrosion paint, anti-rust primer, floor paint, oil tank paint, drinking water tank paint, etc. However, traditional solvent-based coatings contain more than 30% organic solvents. During the process of manufacturing, construction, drying, and curing of coatings, a large amount of VOC is released into the atmosphere, which constitutes extremely serious pollution and harm to the human ecological environment. threaten. The solvent-free epoxy coating has no volatile organic solvents, is non-toxic, and is en...
