Waterborne fireproof heat-insulation paint for wooden building and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, in particular to a water-based fireproof and heat-insulating coating and a preparation method thereof. Background technique [0002] Wood structure buildings are easy to catch fire, and the fire protection of wood structures is essentially the fire protection of wood structure components. People have been researching and exploring ways to effectively protect wooden structures from fire. The methods used mainly include clay veneer fire protection, lath plastering or steel wire plastering veneer fire protection, cement mortar or concrete fire protection, and fire protection boards for wood components, etc., but their protective effects and applicability are not good. Very ideal. Fire-resistant coatings are still the most widely used, most applicable, and most convenient for construction in existing projects. In daily industrial applications, the flame retardant system composed of amm...
