Abstract

The invention discloses a modified high-temperature-resistant composite coating and belongs to the technical field of coating production. The modified high-temperature-resistant composite coating disclosed by the invention is prepared from the following raw materials in parts by mass: 48 to 62 parts of epoxy modified organic silicon resin, 7 to 19 parts of azodicarbonamide, 5 to 10 parts of modified aluminum oxide, 2.8 to 5.8 parts of tricresyl phosphate, 1 to 5 parts of boron nitride, 3 to 10 parts of silicon carbide, 3 to 13 parts of flatting agent, 2 to 10 parts of waterborne silane coupling agent, 2.5 to 7.5 parts of thickening agent, 2 to 11 parts of wetting agent, 4 to 15 parts of pigment and 70 to 110 parts of deionized water. According to the modified high-temperature-resistance composite coating disclosed by the invention, high-temperature-resistant ingredients are added, so that high temperature resistance of the coating is improved; a coating film of the composite coating has the characteristics of being not prone to generating bubbles, hardening and cracking.

Description

technical field [0001] The invention belongs to the technical field of paint production, and in particular relates to a modified high-temperature-resistant composite paint. Background technique [0002] High-temperature resistant coatings, also known as heat-resistant coatings, generally refer to coatings that can maintain proper physical and mechanical properties without discoloration or detachment of the paint film above 200°C, so that the protected object can function normally in a high-temperature environment special paint. High temperature resistant coatings are generally composed of high temperature resistant polymers, pigments and fillers, solvents and additives. Compared with other high-temperature oxidation and corrosion resistance methods, high-temperature-resistant coatings are favored by people for their good performance in large-area construction, low cost, and remarkable effects, and have been widely used for surface protection in high-temperature occasions. ...
