NOVELTY - Fire-resistant heat-insulating coating, comprises component A and component B in a weight ratio of 1:1, where the component A includes 100 pts. wt. hydroxy-terminated polysiloxane, 1-10 pts. wt. white carbon black, 5-50 pts. wt. polysilazane resin, 1-80 pts. wt. hydrogen-containing silicone oil, 10-120 pts. wt. filler, 0.5-10 pts. wt. graphene slurry, and 0-1 pts. wt. reaction inhibitor; and the component B includes 100 pts. wt. hydroxy-terminated polysiloxane, 1-10 pts. wt. white carbon black, 1-80 pts. wt. hydroxy silicone oil, 10-120 pts. wt. filler and 1-500 parts per million catalyst. USE - The fire-resistant heat-insulating coating is useful for delaying thermal diffusion of lithium batteries (claimed). ADVANTAGE - The fireproof heat-insulating paint: has low density; is suitable for lightweight requirements; has excellent fire resistance, flame retardant and heat insulation properties; can coating a 0.7mm wet film coating on the substrate can resist fire at 1500 degrees C for more than 2 hours and backside temperature of lower than 500 degrees C; and has excellent aging resistance, damp heat resistance and high and low temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing fire-resistant heat-insulating coating, comprising (a) stirring and dispersing hydroxy-terminated polysiloxane, polysilazane resin, hydrogen-containing silicone oil, white carbon black, graphene slurry, filler and reaction inhibitor uniformly under vacuum to obtain component A, (b) stirring and dispersing hydroxy-terminated polysiloxane, hydroxy silicone oil, white carbon black, filler and catalyst evenly under vacuum to obtain component B, (c) mixing component A and component B uniformly in a weight ratio of 1:1 to obtain fire-resistant heat-insulating coating.
