The fire-retardant mechanism of the fire-retardant coating can be roughly summarized as the following five points: 1. The fireproof coating has flame retardancy or incombustibility, so that the protected substrate is not directly contacted with air, the ignition of an object is delayed, and the combustion speed is reduced; 2. The fireproof coating has low heat conductivity coefficient besides flame retardancy or incombustibility, and can delay the transmission of flame temperature to a protected substrate; 3. the fire-proof coating is heated to decompose non-combustible inert gas, and dilute combustible gas decomposed by the protected object when heated, so that the protected object is not easy to burn or the burning speed is reduced; 4. The nitrogenous fireproof coating is heated to decompose groups such as NO, NH3 and the like, and the groups are combined with organic free radicals, so that the chain reaction is interrupted, and the temperature is reduced; 5. The expansion type fireproof coating expands and foams by heating to form a carbonaceous foam heat insulation layer to seal a protected object, so that the transfer of heat and a base material is delayed, and the object is prevented from catching fire and burning or the strength is prevented from being reduced due to the rise of temperature.
However, the existing fireproof coating for the air compressor is insufficient in wear resistance, acid and alkali resistance and fire resistance, short in service time and needs to be further enhanced.
