Abstract

The invention relates to an intumescent water-based fireproof and flame-retardant coating for wood materials and a preparation method thereof. The coating comprises water and the following components in parts by weight: 200 parts of melamine-modified urea-formaldehyde resin emulsion, 110 parts of ethylene-vinyl acetate copolymer emulsion ‑120 parts, 20‑24 parts of boric acid, 36‑38 parts of polyphosphate amine, 20‑24 parts of guanylurea phosphate, 36‑40 parts of pentaerythritol, 30‑34 parts of melamine, 1.0‑1.4 parts of sulfonated carbon, 3.6 parts of zinc borate ‑4.0 parts, ammonium octamolybdate 2.0‑2.4 parts, paint additives 16‑20 parts, pigments and fillers 0‑44 parts. The intumescent water-based fireproof and flame-retardant coating can greatly retard the combustion of wood materials during the heating process and inhibit the spread of fire; it has good smoke suppression performance, can delay the time of smoke generation, and reduce the release of smoke and the generation of toxic gases , to provide more safe time and space for the escape and rescue of personnel under fire conditions.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to an intumescent water-based fire-proof and flame-retardant coating for wood materials, and also relates to a preparation method of the above-mentioned intumescent water-based fire-proof and flame-retardant coating for wood materials. Background technique [0002] Wood materials have the advantages of environmental protection, non-toxicity, strong processability and renewable, and are widely used in furniture, construction and interior decoration and other fields. However, untreated wood materials are not fire-resistant, flammable and have fire spread, which will increase the fire risk in the place of use, and there is a serious safety hazard. In order to effectively reduce the occurrence of fires, the country has formulated a series of laws, regulations and safety standards, requiring materials and products used in buildings, indoors or public places to re...
