Abstract

The invention discloses a preparation method of environment-friendly waterborne glass paint with high adhesive force, wherein the preparation method includes steps of placing and grinding waterborne acrylic resin, dispersing agent, pigment, and de-ionized water at ratio in a grinding machine for 30-40 minutes, and making its grain diameter below 10 miu m; adding coupling agent, extinction powder and moistening agent at the ratio; stirring the components for 10-20 minutes at the rotate speed of 800-1000 r / min; grinding the acquired substance in the grinding machine and making its grain diameter as 10 miu m below; adding antifoaming agent, coalescing agent, pH adjusting agent and adhesion promoter at the ratio, and stirring the components for 5-16 minutes at the rotate speed of 700-800 r / min; at last, adding amino resin curing agent and stirring for 4-12 minutes at the rotate speed of 600-700 r / min; at last, detecting the package.

Description

technical field [0001] The invention relates to the field of water-based baking varnish, in particular to a preparation method of an environment-friendly water-based glass baking varnish with high adhesion. Background technique [0002] Water-based glass baking varnish is water-soluble glass baking varnish. Traditional oil-based glass baking varnish uses solvents such as thinner as diluent, while water-based glass baking varnish uses clean water as diluent. Generally, unsaturated polyester paint is used as a film-forming finish paint The film is hard and brittle, and the flexibility is not good. After modification with polyurethane, the flexibility of the paint film is improved, and the wear resistance of the paint film is improved by glass powder and polyethylene wax paste. Existing water-based glass baking varnishes have poor gloss and weather resistance, low hardness and weak adhesion, and even some water-based glass baking varnishes use organic or toxic solvents.
