Baked colorful cracked-glass paint and preparation method thereof

Abstract

The invention relates to the field of glass products, and particularly relates to baked colorful cracked-glass paint and a preparation method thereof. The paint is prepared from a component A and a component B in a weight ratio of 3.5:1, wherein the component A is prepared from the following raw materials: pentaerythritol tetraacrylate, epoxy acrylate, vinyl chloride-vinyl acetate copolymer, vinyltriethoxysilane, amino resin, thermosetting acrylic resin, polyketone resin, dibutyl phthalate, tricresyl phosphate, a silane coupling agent, a dust proofing agent, a wetting agent, a defoaming agent, a flatting agent and a solvent-type metal complex dye solution having a mass concentration of 10 percent; and the component B is a cracking agent. According to the method, proper raw materials and auxiliaries are adopted, so that the paint is applicable to glass base materials, has high hardness, good adhesion, excellent water resistance, acid resistance, alkali resistance and high temperature resistance, has an attractive decorating effect, and has the advantages of bright colors, high luster, good transparency and good cracking effect. The preparation method of the baked colorful cracked-glass paint is simple and reasonable in process.

Description

technical field [0001] The invention relates to the field of glass products, in particular to a baked colored cracked glass coating and a preparation method thereof. Background technique [0002] At present, the alkyd resin used in the market is one of the most widely used varieties of synthetic resins. Due to its good performance, it is the most common in the application of colored glass coatings. There are more -OH and -COOH groups left in the alkyd resin. These genes can make the coating film made of alkyd resin have better adhesion, but the biggest disadvantage of alkyd resin is that the coating film is soft and durable. Poor thermal performance, poor water and alkali resistance, and slow drying speed. The ester group on the resin molecular chain also makes the coating film not resistant to acid and alkali. [0003] Existing glass coatings either have poor adhesion, are easy to fall off, or have low hardness, or are not strong in acid and alkali resistance, or are baked...

There are many remaining -OH and -COOH groups in the alkyd resin. These genes can make the coating film made of alkyd resin have better adhesion, but the biggest disadvantage of alkyd resin is that the coating film is soft and durable. Poor thermal performance, poor water and alkali resistance, and slow drying speed, the ester group on the resin molecular chain also makes the coating film not resistant to acid and alkali

[0003] Existing glass coatings either have poor adhesion, are easy to fall off, or have low hardness, or are not strong in acid and alkali resistance, or are baked at too high a temperature, or are easy to change color when baked at a high temperature, or have poor decorative effects, and the colors are not bright enough. Low gloss, few glass coatings with excellent performance in all aspects
