Description

technical field

[0001] The application belongs to the technical field of coatings, and in particular relates to an inorganic fireproof coating and a preparation method. Background technique

[0002] Fire retardant coatings can improve the fire resistance of materials, slow down the speed of flame spread, or prevent combustion within a certain period of time by brushing paint on the surface of materials. 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. Applied on the surface of flammable substrates to change the combustion characteristics of the material surface to retard the rapid spread of fire; or applied to building components to improve the fire resistance of the components.

[0003] The fire prevention principle of fire retardant coatings can be roughly summarized as th...
