Abstract

The invention discloses a preparation method of an environment-friendly double-component high-temperature-resisting fireproof coating. The preparation method comprises the following steps: adding hydroxyl silicone oil, a flame retarding agent, magnetic filler and a ceramic additive into a grinding machine D under the stirring condition until the mixture is gradually and uniformly dispersed; grinding to a specified fineness to obtain a component A; adding a cross-linking agent, a coupling agent and a catalyst into a high-speed disperser; uniformly mixing to obtain a component B; when in use, uniformly mixing the prepared component A and the prepared component B in a mass ratio of 10 to 1; curing at the temperature of 10 to 50 DEG C to form a film namely high temperature-resisting fireproof coating, wherein the component A contains a hydroxyl silicone oil flame retarding agent, the magnetic filler, the ceramic additive and other heat insulating fillers, the component B contains the cross-linking agent, the coupling agent and the catalyst; when in used, mixing the component A and the component B in a mass ratio of 10 to 1 and curing at the temperature of 10 to 50 DEG C to form a film. The environment-friendly double-component high-temperature-resisting fireproof coating disclosed by the invention is free of an organic solvent and has the characteristics of good expansion performance when meeting fire, high expansion carbonization layer strength, long fire retarding time and the like; the coating is good in heat insulation property and high temperature resistance; the temperature resistance is 800 DEG C or more; the operation is convenient.

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 and he...
