Abstract

The invention discloses water-based facing type fireproof paint. The water-based facing type fireproof paint is prepared from the following raw materials in mass fraction: 18.0-20.0wt% of film forming matter, 23-23.5wt% of a carbon forming catalyst, 10-11wt% of a carbon forming agent, 12-13wt% of a foaming agent, 9-11wt% of pigment filler, 0.49-1.13wt% of auxiliaries, 20-27.5wt% of water, 0-0.8wt% of trisodium phosphate and 0-0.4wt% of a silane defoaming agent. The invention further discloses a preparation method of the water-based facing type fireproof paint. The water-based facing type fireproof paint prepared by the preparation method disclosed by the invention has good fireproof performance, good water resistance, strong adhesive force for a combustible matrix and good decorativeness, and can be used for surface coating of buildings and decorative materials.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a water-based decorative fireproof coating and a preparation method thereof. Background technique [0002] Combustion is a chemical phenomenon of luminescence and heat. It must meet three conditions to occur, that is, flammable substances, combustion aids and ignition sources. When these three conditions exist at the same time and contact each other, they can burn. It can be seen that in order to prevent combustion, any one of the three elements of combustion must be isolated. Because the substance will release a large amount of heat when it burns, it can cause thermal decomposition and combustion of the surrounding combustible substances, so that the combustion will continue to spread and expand. The spread of heat is the main way for combustion to spread, so to prevent the spread of combustion, it is necessary to isolate any form of heat conduction of the protected ...
