Abstract

The invention relates to the technical field of paint and in particular relates to fireproof paint. The fireproof paint comprises the following raw materials in parts by weight: 35-50 parts of diphenylether-formaldehyde resins, 16-27 parts of modified expanded graphite, 12-17 parts of perlite powder, 7-12 parts of yttria powder, 5-9 parts of aluminum dihydrogen tripolyphosphate, 2-6 parts of cellulose acetate, 8-15 parts of ortho-xylene, 5-12 parts of a film-forming agent, 3-9 parts of pentaerythritol, 0.3-1.5 parts of a coupling agent, 1.5-4.5 parts of an antifoaming agent, 0.2-0.6 part of awetting agent, 1.5-2.5 parts of a stabilizer and 0.2-0.7 part of microgel. The fireproof paint disclosed by the invention has excellent fire resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a refractory coating. Background technique [0002] Fire-resistant 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 combustible 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 the components, called refractory coatings. [0003] However, the refractory coatings currently on the market have low refractory properties, resulting in reduced service life, which is difficult to meet market demand. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention propose...
