Abstract

The invention discloses water-based glass baking paint. The water-based glass baking paint comprises the following components in percentage by weight: 10-15% of water-based varnish, 58-60% of water-based matting paste and 25-32% of water-based colorant, wherein the water-based varnish comprises the following components in percentage by weight: 46% of water-based resin, 14% of amino resin, 29.5% of ethanol, 10% of isopropanol, 0.3% of a defoamer and 0.2% of a leveling agent; the water-based matting paste comprises the following components in percentage by weight: 40% of water-based resin, 0.6% of a dispersant, 0.4% of silicon gas, 40% of stone powder and 19% of matting powder; the water-based colorant comprises the following components in percentage by weight: 40% of water-based resin, 0.8% of a dispersant, 10% of pigment and 19.2% of pure water. The water-based glass baking paint has smooth and flat paint film and high hardness, does not contain toxic substances and volatile components, does not affect air, and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of water-based baking varnish, in particular to a water-based glass baking varnish. Background technique [0002] Water-based glass baking varnish is water-soluble glass baking varnish. Traditional oil-based glass baking varnish is added with solvents such as Tianna water as a diluent, while water-based glass baking varnish is added with purified water as a diluent. 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. [0003] Another Chinese patent number is: 201110425604.7, and the publication date is: 2012.7.18, which discloses a water-based glass baking varnish for glass substrates and its preparation method. The baking varnish includes the following components by weight: 30-60 parts of water-soluble resin ; 5-10 parts of 325 amino resin; 15-30 parts of pigment; ...
