Description

technical field [0001] The invention relates to a fireproof coating, in particular to a facing expansion type silica sol water-based fireproof coating for woodware and a preparation method thereof. Background technique [0002] Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of flammable substrates to change the combustion characteristics of the material surface and retard the rapid spread of fire; or applied to building components to...
