Abstract

The invention provides black organic silicon heat resisting paint and a preparation method thereof. The black organic silicon heat resisting paint is prepared from organic silicon resin, black paints, filler, a carbon black dispersant, a solvent, an anti-settling agent and a curing agent in parts by weight. Two black paints are combined in use and the carbon black dispersant is soaked and dispersed in advance, so that the heat resistance and relative blackness of the paint are improved, and the coarseness return condition of the paint is further avoided, and meanwhile, the paint film has a certain blackness and good appearance. The black organic silicon heat resisting paint prepared by the invention has luster and maintains the luster at temperatures above 300 DEG C, and has higher heat resistance. The hardness of the paint film can reach above 0.5, and the hardness of the paint film is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a black silicone heat-resistant paint 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 pr...
