High-gloss water-based paint for perfume glass bottles

Abstract

The invention discloses a high-gloss waterborne coating for perfume glass bottles; the high-gloss waterborne coating comprises a component A, a component B, a component C and a component D which are separately packaged, wherein the component A consists of the following components in parts by weight: 30-50 parts of acrylic resin A, 10-20 parts of acrylic resin B, 3-10 parts of melamine resin A, 3-10 parts of melamine resin B, 1-2 parts of an antifoaming agent, 0.1-0.5 part of a defoaming agent, 1-3 parts of a leveling agent, 5-10 parts of a cosolvent, 1-2 parts of a rheological auxiliary agent,0.2-1 part of an amine neutralizer, 1-5 parts of a silane coupling agent, and 15-20 parts of deionized water; the component B is an acid drier with the amount of 1-2 parts by weight; the component Cis deionized water with the amount of 20-30 parts by weight; the component D is dye slurry with the addition amount added according to the needs. The high-gloss waterborne coating can meet the requirements of FDA, and has the characteristics of high gloss, good fullness, excellent adhesive force on glass substrates, water boiling resistance, alcohol scrubbing resistance and abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-gloss water-based coating for perfume glass bottles. Background technique [0002] Perfume bottles are one of the modern glass products. Consumers have higher and higher requirements for the shape, color and touch of their glass products, thus giving rise to the demand for perfume bottle coatings. [0003] Since perfume contains a lot of organic solvents, the coating used for perfume bottles must not only meet the basic adhesion requirements on glass, but also have strong alcohol resistance and chemical corrosion resistance. [0004] Existing perfume bottle coatings have the following disadvantages: [0005] The solid content of some varieties of paint is low, it is difficult to meet the high-fullness appearance requirements required by customers, and the alcohol resistance is poor when matched with certain dyes, and the color fades seriously. After use, an additional la...

AI Technical Summary

Problems solved by technology

[0005] The solid content of some varieties of paint is low, it is difficult to meet the high-fullness appearance requirements required by customers, and the alcohol resistance is poor when matched with certain dyes, and the color fades seriously. After use, an additional layer of high-gloss varnish is required. The process is increased, which seriously affects the production capacity of the production line and causes waste of raw materials; moreover, this kind of paint contains more than 60% of co-solvent, which is a large amount of co-solvent, and it is actually a water-soluble paint, which cannot meet the requirements of The definition of water-based coatings in HJ2537-2014 does not belong to water-based coatings in essence, and also violates the original intention of the government to reduce the impact of coatings on the environment and human health during production and use, and to protect the environment.

[0006] Although the solid content of some products can meet the needs of customers, they have high requirements for baking conditions, and it is difficult to meet the conditions of customers' current production lines. Compliant, especially resistance to boiling water and alcohol wipes
