Can paint be fireproof?

Combustion is a rapid and violent oxidation reaction with flames. The reaction is very complex. Three conditions must be met at the same time for the generation and progress of combustion, namely combustible substances, combustion aids (such as air, oxygen or oxidants) and fire sources (such as High temperature or flame). In order to prevent the combustion from proceeding, any one of the three elements in the combustion process must be cut off, such as lowering the temperature, isolating the air or combustibles.

The fireproof mechanism of fireproof coatings can be roughly summarized into the following five points:
(1)The fire-retardant coating itself is flame-retardant or non-combustible, so that the protected substrate does not directly contact the air, delaying the object's ignition and reducing the burning speed.

(2) In addition to its own flame retardancy or non-combustibility, the fireproof coating also has a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected.
(3) Fire-resistant paint decomposes non-combustible inert gas when heated, dilutes the combustible gas decomposed by heating of the protected object, so that it is not easy to burn or the burning speed is slowed down.
(4) Nitrogen-containing fireproof coatings decompose NO, NH3 and other groups when heated, and combine with organic free radicals to interrupt the chain reaction and reduce the temperature.
(5)The intumescent fireproof coating expands and foams when heated to form a carbon foam heat insulation layer to seal the protected object, delay the transfer of heat and the substrate, and prevent the object from catching fire or reducing the strength caused by the increase in temperature.
