Abstract

The invention discloses an environment-friendly double-component high-temperature-resistant fireproof paint which is composed of a component A and a component B, wherein the component A contains a hydroxy silicon oil flame retardant, a magnetic filler, a ceramic assistant and other thermal-insulation fillers; and the component B contains a crosslinking agent, a coupling agent and a catalyst. When the paint is in use, the component A and component B are mixed according to the mass ratio of 10:1, and cured to form the film. The paint is free of any organic solvent, and has the characteristics of favorable expansion character when meeting fire, high strength of the expanded carburization layer, long fireproof time and the like. The coating has the advantages of favorable heat insulation property and favorable high temperature resistance, and can resist the high temperature of 800 DEG C above.

Description

Technical field: [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly two-component high-temperature-resistant fireproof coating and a preparation method thereof. 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 falling off of the paint film above 200°C, so that the protected objects can function normally in high temperature environments Special functional coatings. Silicone resin, because it has an organic-inorganic main chain structure "Si-O-Si", greatly enhances the bond energy, and endows silicone resin with higher heat resistance and fire resistance than all pure organic resins. Silicone high-temperature-resistant coatings have good heat resistance, water resistance, electrical insulation and good mechanical properties, but their heat-resistant an...
