Embodiment 1

[0024] According to the high hardness water-based white glass baking paint in Example 1 in Table 1, add deionized water into the dispersing kettle according to the weight ratio of the formula, add bactericide, propylene glycol, wetting agent, adhesive agent, and acid catalyst under stirring and disperse for 30-40 minutes. Add water-based acrylic resin, amino resin, water-based polyurethane acrylic hybrid, water-based inorganic silicone resin and stir evenly, add water-based titanium white slurry, PH regulator, defoamer, and then add film-forming aids, leveling agents, and thickeners at a uniform speed. Thickener, stirring to adjust the viscosity and pH value, that is, a high-hardness water-based white glass baking varnish is prepared.

Embodiment 2

[0026] Example 2 Refer to Example 1 for the preparation steps of high-hardness water-based black glass baking varnish.

Embodiment 3

[0028] Example 3 Refer to Example 1 for the preparation steps of the high-hardness water-based golden glass baking varnish.

Abstract

The invention relates to a preparation method for a high-hardness water-based glass baking paint composed of nano water-based acrylic resin, low-methoxylation amino resin, a water-based polyurethane acrylic hybrid, hardening resin, a colorant, a substrate wetting agent, an adhesive agent, an acid catalyst, a film-forming auxiliary agent, a defoaming agent, an anti-scratch flatting agent, a thickening agent, a bactericide, a pH regulator, a cosolvent and water. The prepared water-based glass baking paint has the advantages of low VOC, no pollution to the environment, no poison and harm to operators, strong coating film adhesive force, good flexibility, high hardness, excellent wear resistance, excellent water resistance, excellent alcohol resistance, excellent salt fog resistance, simple construction, and stable storage. A prepared paint film has the hardness reaching 5 H or more, and has anti-scratch and wear-resistance properties of a ceramic glaze film; a prepared glass product achieves effects of blue and white porcelain, enamel colored glaze porcelain, and white glazed porcelain; and the water-based glass baking paint is widely used for surface protection and decoration of wine bottles, perfume bottles, glass products, lamps, woodware, metals, plastics and other products.

Description

technical field [0001] The invention relates to a preparation method of water-based glass varnish, in particular to a high-hardness water-based baking varnish suitable for various glass substrates. Background technique [0002] The coating protection and decoration of glass and glass products have a wide range of needs in industrial and civil fields, such as wine bottles, perfume bottles, lighting, home decoration glass products and glass instruments, etc., all need to be coated with protective and decorative coatings on the surface. At present, most of the glass coatings used in China are solvent-based products. With the improvement of people's environmental protection awareness and the improvement of environmental protection laws and regulations, the application of water-based coatings on glass has received great attention. The one-component water-based glass paint prepared by polyurethane water dispersion, water-soluble polyacrylic resin, urethane type and modified acryli...
