10. A method of preparing a fire retardant coating according to any one of claims 1 to 9, comprising the steps of:
step 1, weighing the components according to a designed proportion, and mixing the composite foaming agent with water according to a mass ratio of 1:48-52 to obtain a foaming agent aqueous solution;
step 2, foaming the foaming agent aqueous solution, charging nitrogen, and stirring to obtain nitrogen foam;
And step 3, uniformly mixing the basalt fiber with the residual water, then adding aluminum silicate, bentonite, silicon dioxide, quartz powder, white cement and water glass, uniformly stirring, and then introducing nitrogen foam to obtain the fireproof coating.
