Abstract

The invention relates to an expansive waterborne fireproof and flame-retardant coating for a wood material and a preparation method of the expansive waterborne fireproof and flame-retardant coating. The coating comprises water and the following components in parts by weight: 200 parts of melamine-modified urea resin emulsion, 110-120 parts of ethylene-vinyl acetate copolymer emulsion, 20-24 partsof boric acid, 36-38 parts of ammonium polyphosphate, 20-24 parts of guanylurea phosphate, 36-40 parts of pentaerythritol, 30-34 parts of melamine, 1.0-1.4 parts of sulfonated carbon, 3.6-4.0 parts ofzinc borate, 2.0-2.4 parts of ammonium octamolybdate, 16-20 parts of coating auxiliaries and 0-44 parts of pigment and filler. When heated, the expansive waterborne fireproof and flame-retardant coating is capable of greatly retarding the combustion of the wood material so as to prevent fire spreading; and the expansive waterborne fireproof and flame-retardant coating has good smoke inhibiting property and is capable of delaying the smoke generation time, reducing the release amount of smoke and the generation of poisonous gases and providing more safety time and space for escape and rescue of personnel under the condition of a fire hazard.

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...
