Problems solved by technology

Its main disadvantages are: it needs to use a lot of organic solvents to dilute in the construction of shower coating, which has heavy smell, high toxicity, lack of protection for personnel, and poor environmental protection effect; the adhesion (on flat and spherical surfaces) is not strong enough, water resistance, water resistance The wiping performance of alcohol is poor, far inferior to that of baking varnish; the construction is greatly affected by the climate; precipitation is easy to occur after dilution, which affects subsequent use

Abstract

The invention discloses water- soluble stoving varnish suitable for craft glass products. The components of the ingredients of the water- soluble stoving varnish comprise, by weight, 28%-35% of water- soluble acrylic resin, 6%-9% of water-soluble methylated amino resin, 3%-5% of silicon dioxide flatting agent, 5%-8% of superfine magnesium powder, 10%-14% of Butyl cellosolve, 15%-20% of absolute ethyl alcohol, 13%-17% of water, 0.2%-0.5% of self-emulsifying modified polyacrylate, 0.2%-0.5% of fluorocarbon modified polyacrylate, 0.2%-0.5% of modified polysiloxane and 2%-6% dimethylethanolamine. The invention further discloses a preparation method of the water-soluble stoving varnish. Usage of organic solvent can be greatly reduced in a coating construction process of the water-soluble stoving varnish, and the water-soluble stoving varnish is environment-friendly and good in performance.

Description

technical field [0001] The invention relates to a water-soluble baking varnish suitable for craft glass products and a preparation method thereof. Background technique [0002] At present, most of the coatings for craft glass products use mature self-drying acrylic modified self-drying paint, which is composed of acrylic resin with a certain glass transition temperature, a small amount of nitrocellulose, epoxy resin, additives and organic solvents. modulated. Its main disadvantages are: it needs to use a lot of organic solvents to dilute during the spraying construction, which has heavy smell, high toxicity, lack of protection for personnel, and poor environmental protection effect; the adhesion (on flat and spherical surfaces) is not strong enough, water resistance, water resistance The wiping performance of alcohol is poor, far inferior to that of baking paint; the construction is greatly affected by the climate; precipitation is easy to occur after dilution, which affect...
