Problems solved by technology

[0006] Therefore, if the bottom-surface-integrated coating process is used, there will be an embarrassing problem that the coating manufacturer does not accept orders or waste orders if the amount is small: when companies in the advertising production industry need bottom-surface-integrated coatings of various colors or different gloss, Send samples to paint manufacturers for production, but if the amount used is too small to meet the minimum order quantity, the paint manufacturer is unwilling to produce paint of this color due to the calculation of production costs. waste

Embodiment 1

[0043] (Example 1, the color-matching coating that combines bottom and surface)

[0044] The bottom-surface-integrated color-matching paint of this embodiment includes a color masterbatch component, a light-reducing resin component, a high-gloss resin component and a curing agent component. The ratio of the mass sum of the color masterbatch component, the light-reducing resin component and the high-gloss resin component to the mass of the curing agent component is 3:1-5:1.

[0045] The masterbatch component is composed of the following components by weight: 30-60 parts of epoxy-modified hydroxyacrylic resin, 25-60 parts of color paste, 0.4-1 part of leveling agent, 1-2 parts of drier, adhesion Accelerator 1-3 parts, first organic solvent 5-15 parts.

[0046] The color paste includes titanium white paste, carbon black paste, organic red paste, iron oxide red paste, iron oxide yellow paste, permanent purple paste, organic medium yellow paste, organic brilliant yellow paste, tra...

Embodiment 2

[0073] (Example 2, the color-matching coating that combines the bottom surface)

[0074] The bottom surface of the present embodiment unites the color matching coating, and all the other are identical with embodiment 1, and difference is:

[0075] The masterbatch components of 12 colors are composed of the following components by weight:

[0076] Medium-concentration white masterbatch components: 35 parts of epoxy-modified hydroxyacrylic resin, 60 parts of titanium white paste, 0.7 parts of leveling agent, 1.5 parts of drier, 2 parts of adhesion promoter, and 10 parts of the first organic solvent.

[0077] Medium-concentration black masterbatch components: 60 parts of epoxy-modified hydroxyacrylic resin, 25 parts of carbon black slurry, 0.7 parts of leveling agent, 1.5 parts of drier, 2 parts of adhesion promoter, and 10 parts of the first organic solvent.

[0078] Medium-concentrated scarlet masterbatch: 35 parts of epoxy-modified hydroxyacrylic resin, 50 parts of organic sc...

Embodiment 3

[0091] (Example 3, the color-matching coating that combines the bottom surface)

[0092] The bottom surface of the present embodiment unites the color matching coating, and all the other are identical with embodiment 1, and difference is:

[0093] The masterbatch components of 12 colors are composed of the following components by weight:

[0094] Medium-concentration white masterbatch components: 35 parts of epoxy-modified hydroxyacrylic resin, 60 parts of titanium dioxide, 1 part of leveling agent, 2 parts of drier, 3 parts of adhesion promoter, and 15 parts of the first organic solvent.

[0095] Medium-concentration black masterbatch components: 60 parts of epoxy-modified hydroxyacrylic resin, 25 parts of carbon black slurry, 1 part of leveling agent, 2 parts of drier, 3 parts of adhesion promoter, and 15 parts of the first organic solvent.

[0096] Medium-concentrated scarlet masterbatch: 35 parts of epoxy-modified hydroxyacrylic resin, 50 parts of organic scarlet pulp, 1 ...

Abstract

The invention discloses a primer-topcoat integrated color matching coating and a preparation method thereof. The color matching coating comprises a color master batch component, a light-reducing resincomponent, a high-gloss resin component and a curing agent component. The color matching coating is dried at room temperature, has excellent adhesive force on various metal and nonmetal base materials such as steel plates, iron plates, aluminum alloys, pure aluminum base materials, galvanized plates, stainless steel plates, ABS, organic glass, PVC, PC and aluminum-plastic plates, is wide in application materials, and adapts to the diversity of sample plate materials in the advertising industry. The color matching coating has the effects of sealing, isolation, moisture prevention and mildew prevention of a primer, and also has the decoration and protection functions of a finish paint.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a color-matching coating which is dried at room temperature and integrates bottom and surface, and a preparation method thereof. Background technique [0002] Surface coating is an essential process in the production of outdoor billboards and signs. The traditional coating process is: pre-treatment - primer - topcoat. With the continuous progress and development of the paint industry, more and more consumers recognize the bottom-surface-integrated paint because of its environmental protection performance. Based on the output in 2014, the annual production of 16.4819 million tons of coatings using traditional coatings, if the use of bottom-surface-integrated coatings, the annual production of coatings can be reduced by 6 million tons, a drop of about 36%, and the toxic and harmful gases emitted will be reduced by nearly 30%.
