Problems solved by technology

[0004] The fireproof coating in the above patent is directly applied on the surface of the steel structure. Under the conditions of alternating seasons, sun and rain, and other large temperature differences, phenomena such as thermal expansion and contraction will occur, resulting in different stresses between the steel member and the fireproof layer. Under the condition of hollowing, the coating is easy to peel off

Abstract

The invention discloses a fire-proof paint interface agent and a preparation method thereof, and relates to the technical field of building fire-proof paint. A technical key point thereof is that thefire-proof paint interface agent comprises the following components in parts by weight: 30-40 parts of perlite, 480-520 parts of vermiculite powder, 180-220 parts of floating beads, 400-450 parts of coal ash, 310-350 parts of light calcium carbonate, 280-320 parts of vinyl acetate-ethylene copolymer emulsion, 80-120 parts of polyvinyl alcohol, 8-12 parts of wood fibers, 2-4 parts of a water-basedthickener, 70-90 parts of talcum powder, and 900-1100 parts of water. The fire-proof paint interface agent has the advantages of high bonding strength, and difficult occurrence of hollow and crackingphenomena.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, more specifically, it relates to a fireproof coating interface agent and a preparation method thereof. Background technique [0002] 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] A Chinese invention patent with the publication number CN104789068A discloses a fireproof coating for steel structures. The mass parts of each component are: 30-40 parts of film-forming base material, 2-5 parts of auxiliary base material, and 2-5 parts of combustion e...
