Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based swelling fireproof coating and a preparation method thereof. Background technique [0002] 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 improve the fire resistance limit of components, called fire retardant coatings. There are many types of fire retardant coatings, but according to the use of fire retardant coatings and the coating thickness of fire retardant coatings, they are generally divided into decorative coatings and steel structure fire retardant coatings. Facing fire retardant coatings are generally used as protective materials for combustible substrates. They have certain decorative and fireproof properties, and are divided into two categories: water-based and solvent-based. The steel structure fireproof coating is main...
