Abstract

The invention relates to the technical field of paints, in particular to heat-resistant paint and a preparation method thereof. The heat-resistant paint is prepared from the following components in parts by mass: 8-12 parts of tung oil, 3-5 parts of quartz powder, 1-3 parts of aluminum phosphate, 4-9 parts of polyarylsulfone resin, 4-9 parts of polyimide resin, 5-7 parts of butanol, 3-7 parts of nonisocyanate polyurethane, 2-4 parts of china clay, 2-4 parts of talcum powder, 5-8 parts of cobalt iso-octoate, 0.2-1.2 parts of an anti-settling agent, 8-18 parts of a curing agent and 2-6 parts of an anti-cracking agent. The heat-resistant paint has the benefits that 1 the heat-resistant paint prepared by mixing the tung oil, the polyarylsulfone resin, the polyimide resin, the butanol, the nonisocyanate polyurethane, the talcum powder and the cobalt iso-octoate is good in heat-resistant effect, and has excellent physical and chemical properties such as the decorative property, the heat resistance, the salt fog resistance, the salt water resistance, the water resistance, the cold tolerance, the oil resistivity, the hydrocarbon solvent resistance, the adhesive force, the impact strength and the flexibility.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-resistant paint and a preparation method thereof. Background technique [0002] Paint can be seen everywhere in daily life. It mainly plays the role of protection and decoration. According to different use environments, there are various types of paint. Traditional paints generally have heavy odor, easy to fall off, easy to corrode, and not environmentally friendly, etc. The problem is that it can no longer meet the requirements of consumers for the use of paint. Therefore, it is necessary to improve the formula of the original paint, increase the practicability and durability of the paint, reduce its harm to the environment and human body, and make it adaptable to various use environments. condition. [0003] Moreover, most of the heat-resistant coatings used to coat high-temperature-resistant metal components and equipment on the market now have a paint film that does ...
