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.
