Abstract

The invention relates to paint with high temperature resistance and a preparation method, in particular to two-component paint with high temperature resistance and a preparation method. The two-component paint with high temperature resistance is prepared from a first component and a second component, wherein the first component is prepared from phenyl methyl silicone resin, a wetting dispersant, a copper chromite black pigment, mica powder, barium phosphonate, zinc phosphate, glass powder and n-butyl acetate in proportion; the second component is prepared from gamma-aminopropyltriethoxysilane and absolute ethyl alcohol in equal proportion through mixing, the two components in a ratio being (100:1)-(105:1) in parts by weight are mixed, and the two-component paint with high temperature resistance is obtained. The temperature resistance, the discoloration resistance and the alternate cooling and heating resistance of the two-component paint with high temperature resistance are greatly improved, and adhesive force and corrosion resistance of the two-component paint with high temperature resistance are excellent.

Description

technical field [0001] The invention relates to a high-temperature-resistant paint and a preparation method thereof, in particular to a two-component high-temperature-resistant paint and a preparation method thereof. Background technique [0002] High temperature resistant paint, also known as high temperature resistant paint, high temperature paint, heat resistant paint, is a paint that can withstand high temperature oxidation and corrosion by other media. Silicone high-temperature resistant paint has protective functions such as anti-corrosion, waterproof, oil-proof, chemical resistance, light resistance, and temperature resistance. Objects are exposed to the atmosphere and are eroded by oxygen, moisture, etc., resulting in damages such as metal corrosion, wood decay, and cement weathering. Apply high temperature resistant paint on the surface of the object to form a protective film, which can prevent or delay the occurrence and development of these damage phenomena, and ...
