Problems solved by technology

Although the commonly used silicone high-temperature resistant coatings have excellent high-temperature resistance, this requirement is far from meeting the heat-resistant requirements of some special products; in addition, these heat-resistant coatings cannot be used without high-temperature baking. Barbecue with an open flame, otherwise a lot of smoke will be generated, and it cannot be constructed under high temperature conditions above 200°C, and it cannot withstand high temperatures above 800°C. Its use range and application are relatively small
Existing silicone high temperature resistant coatings have poor drying properties at room temperature, generally have to be dried, and have problems such as poor mechanical strength, adhesion and corrosion resistance

Abstract

The invention provides organic silicon heat-resistant finish paint and a preparation method thereof. The organic silicon heat-resistant finish paint consists of an organic silicon resin, aluminum powder, mica powder, talcum powder, an anti-settling agent, a solvent and the like. The organic silicon heat-resistant finish paint has good high-temperature performance and high drying property, is subjected to surface drying within an hour and is subjected to hard drying within four hours; the adhesion force and corrosion resistance of the organic silicon heat-resistant finish paint are obviously improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an organosilicon heat-resistant topcoat and a preparation method thereof. Background technique [0002] Some equipment, such as exhaust pipes of automobiles, high-temperature reactors in petrochemical plants, and boilers in thermal power plants, are often in high-temperature and corrosive media. Their synergy will accelerate the corrosion and perforation of equipment, increase equipment maintenance costs, and affect production safety. pose great dangers. For the problem of high temperature oxidation corrosion of metal equipment, the use of high temperature resistant and anti-oxidation coating protection is an effective method. [0003] Most of the heat-resistant coatings used to coat high-temperature-resistant metal components and equipment on the market today, the paint film does not change color or fall off above 200°C, and still maintains appropriate physical and mechanical ...
