Abstract

The invention discloses a high-temperature trip temperature heat-resistant coating which comprises a component A and a component B according to a mass ratio of 2:1, wherein the component A contains the following components in parts by weight: 15-30 parts of floating aluminum paste, 5-15 parts of barium sulfate, 5-10 parts of mica powder, 3-8 parts of zinc phosphate, 3-8 parts of aluminium triphosphate, 0.5-1 part of an anti-settling agent, 0.5-1 part of a thixotropic agent, 40-60 parts of a modified silicone polymer, 8-15 parts of diethylene glycol monobutyl ether and 0.2-0.5 part of an antifoaming agent; and the component B contains the following components in parts by weight: 2-3 parts of dioctyl phthalate and 2-3 parts of diethylene glycol monobutyl ether. The coating prepared by the formula disclosed by the invention is capable of performing construction in an environment of 300 DEG C or below, so that some production equipment which needs to be subjected to coating maintenance andhas high temperature can be directly maintained during production, and maintenance can be performed without shutdown and suspend production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature and heat-resistant coating. Background technique [0002] In order to protect some facilities or equipment with steel structures or cement concrete structures, and increase their heat resistance, fire resistance and corrosion resistance, etc., it is usually necessary to coat their surfaces with protective coatings. [0003] However, the existing protective coatings can only be applied under the environment below 60°C. If the construction temperature exceeds 60°C, the solvent will volatilize very quickly and the coating will thicken, making it difficult to flow the coating and affecting the construction quality; at the same time, during the film forming process , If the temperature is too high, the solvent on the surface of the coating will volatilize rapidly, but the solvent inside the coating will not easily volatilize, thus making it difficult to form a film...
