The invention belongs to the technical field of functional coatings, and in particular relates to a water-based fireproof and heat-insulating
coating for wooden buildings and a preparation method thereof. The water-based fireproof and heat-insulating paint for wooden buildings mainly includes the following raw materials in parts by weight: 25-30 parts of
silicon acrylic
emulsion, 10-15 parts of
ammonium polyphosphate, 6-8 parts of
melamine, 3-6 parts of
pentaerythritol, and
rutile titanium dioxide 10-15 parts, 3-6 parts of hollow glass microspheres, 2-5 parts of
sericite, 2.5-6 parts of hollow
ceramic microspheres, 2-4 parts of nano far-
infrared ceramic powder, 4-7 parts of diatomaceous earth, water-based
enhancer 0.5-1 part of thickener, 0.2-0.4 part of water-based
defoamer, 0.4-0.8 part of water-based
wetting and dispersing agent, 0.1-0.3 part of water-based
antifungal agent, 1-2 parts of film-forming aid, 20-30 parts of deionized water share. The method of the invention is simple, and the prepared
coating is fireproof, heat-insulating,
mildew-proof, high in adhesion, good in
aging resistance, widely used and
environmentally friendly, and can be used in wooden buildings for
flame-retardant, reducing the temperature rise caused by strong
sunlight radiation, and preventing indoor The heat is lost to the outside and other aspects have achieved beneficial effects, effectively protecting the building and saving energy.
