Embodiment 1

[0064] The water-based UV silver powder coatings in Example 1 are listed in Table 1 in parts by mass.

[0065] Table 1 Composition of waterborne UV silver powder coating components

[0066] Waterborne UV silver powder coating parts by mass Polycarbonate Modified Acrylic Emulsion 60 Waterborne PUD resin 14 D 1.4 Defoamer 0.1 pH regulator 0.2 Dispersant 0.6 Thixotropic agent A 0.4 leveling agent 0.7 matting powder 2 Thixotropic agent B 1.6 silver powder 4 Co-solvent 6 Photoinitiator 3 Deionized water 4

[0067] In this embodiment, there are 0.4 parts of thixotropic agent A and 1.6 parts of thixotropic agent B, and the mass ratio of thixotropic agent A to thixotropic agent B is 1:4.

[0068] The preparation method of above-mentioned waterborne UV silver powder coating is as follows:

[0069] (1) Put the polycarbonate modified acrylate emulsion into the container and stir and disper...

Embodiment 2

[0073] The water-based UV silver powder coatings in Example 2 are listed in Table 2 in parts by mass.

[0074] Table 2 Composition of waterborne UV silver powder coating components

[0075] Waterborne UV silver powder coating parts by mass Polycarbonate Modified Acrylic Emulsion 60 Waterborne PUD resin 14 D 1.4 Defoamer 0.1 pH regulator 0.2 Dispersant 0.6 Thixotropic agent A 1 leveling agent 0.7 matting powder 2 Thixotropic agent B 1 silver powder 4 Co-solvent 6 Photoinitiator 3 Deionized water 4

[0076] Compared with Example 1, the difference in components of this example is 1 part of thixotropic agent A and 1 part of thixotropic agent B, and the mass ratio of thixotropic agent A to thixotropic agent B is 1:1.

[0077] The preparation method of the above-mentioned water-based UV silver powder coating is the same as that of Example 1, and the water-based UV silver powder coating...

Embodiment 3

[0079] The water-based UV silver powder coatings in Example 3 are listed in Table 3 in parts by mass.

[0080] Table 3 Composition of waterborne UV silver powder coating components

[0081]

[0082]

[0083] Compared with Example 1, the difference in components of this example is that thixotropic agent A is 1.6 parts, thixotropic agent B is 0.4 parts, and the mass ratio of thixotropic agent A to thixotropic agent B is 4:1.

[0084] The preparation method of the above-mentioned water-based UV silver powder coating is the same as that of Example 1, and the water-based UV silver powder coating 3 is finally obtained.

Abstract

The invention discloses a water-based UV silver powder coating and a preparation method thereof. The coating comprises the following components in parts by weight: 50-70 parts of polycarbonate modified acrylate emulsion, 4-24 parts of waterborne polyurethane resin, 0.4-1.6 parts of a thixotropic agent A, 0.4-1.6 parts of a thixotropic agent B, 0.7-1.9 parts of a base material wetting agent, 0.1-0.2 part of an organic amine regulator, 0.3-0.7 part of a dispersing agent, 1-4 parts of extinction powder, 0.05-0.2 part of a defoaming agent, 0.4-0.7 part of a leveling agent, 2-5 parts of a photoinitiator, 3-10 parts of a cosolvent, 5-15 parts of silver powder and 1-5 parts of deionized water; the thixotropic agent A is an alkali swelling type thickening agent; and the thixotropic agent B is an inorganic thickening agent. The water-based UV silver powder coating has the advantages of being bright in color, high in metal texture and resistant to water boiling, and can be applied to spraying ofplanes of various products.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based UV silver powder coating and a preparation method and application thereof. Background technique [0002] Silver powder (also known as aluminum powder) coatings are widely used due to their good decorative properties, especially in the coloring of various electronic products. Mobile electronic consumer goods have become an indispensable part of people's life. Consumers not only have clear demands on the functions of the products, but also have high requirements on the color and appearance of the products. Generally, the color of the products is realized by spraying paint. , Appearance function. Silver powder coatings are widely used due to their good decorative properties. Due to its flaky structure, silver powder has alignment problems in the paint. If the arrangement of silver powder is not well controlled, the color will not meet the requirements, and it is not...
