Problems solved by technology

For example, the patent application number is CN201210255388.0, which discloses a high-temperature-resistant and low-temperature quick-drying hammer paint, mainly through silicone resin, non-leafing aluminum powder, sec-butyl acetate, glass powder, hammer grain additives and xylene, It solves the high temperature resistance, quick drying and anti-corrosion performance of the existing hammer paint. The formula contains xylene toxic solvent, which does not meet the requirements of low toxicity and environmental protection, and the color is single and there is no mention of resistance to 500 ° C for a longer time or higher temperature When its technical effect; Application Patent No. CN200810211114.5 discloses a kind of environment-friendly polyurethane hammer pattern paint, which is mainly formed by mixing three components according to a certain weight ratio, so that the paint film has bright colors, clear texture, and good hammer pattern effect. The paint film has high hardness, does not contain triphenyl, and has the characteristics of low VOC, but it does not mention the technical effects of specific hammer effect, temperature resistance and color stability of hammer paint
The journal "Scientific Chinese" published the paper "Technical Research on High Temperature Resistance of Hammer Paint", through self-crosslinking silicone modified resin, non-leafing aluminum powder, glass powder, hammer additives, xylene, acetic acid Secondary butyl ester, which has excellent hammer appearance and anti-corrosion properties, can withstand 500 ° C for a long time. However, it has the defects of single color and toxic solvents containing xylene, and there is no mention of resistance to 500 ° C for a longer time Its technical effect at or higher temperature

Abstract

The invention discloses high-temperature resistant low-toxicity hammer spray paint. The formula comprises the following components in parts by weight: 26.0-36.0 parts of modified organic silicon resin, 5.0-8.0 parts of modified alkyd resin, 8.0-15.0 parts of pigment filler, 0.2-0.8 part of hammer agent, 0.2-0.6 part of dispersing agent, 0.02-0.1 part of deodorant, 0.5-2.0 parts of rheological agent and 39.0-58.0 parts of solvent. The hammer spray paint has the following beneficial effects: (1) the paint film has high temperature resistance; (2) due to the resin and solvent without 'three benzenes', the content of 'three benzenes' is controlled from the source, and the requirements for low toxicity and environmental protection can be met; (3) the paint film has clear lines, moderate-size patterns, strong stereoscopic impression, multiple color types and good stability; (4) the construction operation is flexible, simple and convenient, and the product quality is high; (5) by adding the deodorant, the product smell is improved, and an anti-counterfeiting effect can be realized according to the essence type. The invention also discloses a preparation method of the high-temperature resistant low-toxicity hammer spray paint.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant and low-toxicity hammer pattern spray paint and a preparation method thereof. Background technique [0002] The surface of the paint film of hammer spray paint is uneven and has a three-dimensional hammer effect, which can cover defects such as unevenness and smoothness of the substrate and uneven color. It has strong decoration and rich colors, and improves the aesthetics and added value of the product. The operation is flexible and simple during construction. It is widely used in decorative metal, glass, ceramics and other materials. However, ordinary hammer-like spray paint has poor color stability, easy to change color, and lacks high temperature resistance. Generally, the heat resistance is around 80 ° C, and cannot Suitable for occasions with higher temperature and harsher corrosive environment. High-temperature resistant spray paint refers to...
