Embodiment 1

[0023] See formula 1 in formula table 1 for details

[0024] According to formula 1, take 45 parts of water-soluble acrylic resin, 1.0 part of defoamer, 0.3 part of wetting agent, 0.5 part of leveling agent, 0.4 part of dispersant and 20 parts of water into the stirring tank , under the condition of 400-600r / min speed, stir for 3-5min to mix evenly, add 10 parts of water-based transparent color paste, stir and disperse at a high speed of 800-1000r / min for about 30min, then add 1.2 parts of even Mixing agent, 5 parts of methyl etherified amino resin, 17 parts of water, stirring at 300-500 rpm for 3-5 minutes to form a uniform coating system is to complete the preparation process of the above-mentioned baking varnish.

[0025] When using the above-mentioned water-based glass baking varnish, add water 0.5 times of the water-based baking varnish to adjust to the construction viscosity, apply it on the glass substrate, and finally bake at high temperature. Baking, leveling, removi...

Embodiment 2

[0027] See formula 2 in formula table 1 for details

[0028] According to formula 2, take 50 parts of water-soluble acrylic resin, 1.2 parts of defoamer, 0.4 parts of wetting agent, 0.5 parts of leveling agent, 0.3 parts of dispersant and 25 parts of water into the stirring tank , under the condition of 400-600r / min speed, stir for 3-5min to mix evenly, add 8 parts of matting slurry, stir and disperse at a high speed of 800-1000r / min for about 30min, then add 1.5 parts of coupling Agent, 5.6 parts of methyl etherified amino resin, 7.2 parts of water, stirred at 300-500 rpm for 3-5min to form a uniform coating system and complete the preparation process of the above baking varnish.

[0029] When the above-mentioned water-based glass baking paint is used, add 1 times the water of the water-based baking paint to adjust to the construction viscosity, apply it on the glass substrate, and finally bake at high temperature. Baking, leveling, and removing water; baking time is about 1...

Embodiment 3

[0031] According to formula 3, take 63 parts of water-soluble acrylic resin, 1.5 parts of defoamer, 0.4 parts of wetting agent, 0.5 parts of leveling agent, 0.4 parts of dispersant and 5 parts of water into the stirring tank , under the condition of 400-600r / min speed, stir for 3-5 minutes to mix evenly, add 10 parts of water-based transparent color paste and 5 parts of pearl paste, stir and disperse at 800-1000r / min for about 30 minutes, and then pour into the stirring tank in turn Add 1.5 parts of coupling agent, 7 parts of methyl etherified amino resin, and 6.1 parts of water, and stir at 300-500 rpm for 3-5 minutes to form a uniform coating system to complete the preparation process of the above baking varnish.

[0032] When using the above-mentioned water-based glass baking varnish, add water 0.8 times of the water-based baking varnish to adjust to the construction viscosity, apply it on the glass substrate, and finally bake at high temperature. Baking, leveling, and remo...

Abstract

The invention discloses a water-based baking paint for a glass substrate and a preparation method and the application thereof; the formula of the water-based glass baking paint comprises the following components in parts by weight: 45 to 63 percent of water-soluble acrylic resin, 5 to 7 percent of methylated amino resin, 5 to 15 percent of water-based paste, 1.2 to 1.5 percent of coupling agent, 2 to 5 percent of additive and 25 to 30 percent of deionized water. When the baking paint is prepared, first the water-soluble acrylic resin, defoamer, wetting agent, leveling agent, dispersant and some water are sequentially added into a stirring tank to be stirred, is added with the water-based slurry and the like to be stirred and dispersed at high speed; and finally the methylated amino resin, the coupling agent and the rest water are sequentially added in to be stirred into a uniform coating system. The invention also provides a use method of the glass baking paint. When being applied to ground glass, hard glass and other substrates, the coating has the advantages of simple preparation process, convenient construction, strong coating adhesion, high hardness, water resistance, good heat resistance and the like.

Description

technical field [0001] The invention relates to a water-based baking varnish for glass substrates and a preparation and use method thereof. Background technique [0002] The special optical properties of glass make it widely used in daily use. In the application process of glass daily necessities, people put forward high requirements on the anisotropy of the color of glass daily necessities. It is difficult to meet people's requirements for color only from the manufacturing process of glass. Water-based glass baking varnish is mainly aimed at the coloring of glass products, and is used to beautify and modify the surface of glass products; using water as a solvent greatly reduces the emission of VOC (organic volatile compounds) in the formula, which is environmentally friendly type coating products. Contents of the invention [0003] In view of the above-mentioned situation, the object of the present invention is to provide a kind of environmental protection water-based ...
