The invention discloses a clean wood flame retardant without pollution. The wood flame retardant has the main components of water and dicyandiamide, and is characterized by further comprising 5-10 parts of sodium molybdate, 10-20 parts of phisphorylated castor oil, 5-10 parts of ammonium polyphosphate and 0.5-1 part of ultrafine zinc borate. Compared with the prior art, the wood flame retardant has the following beneficial effects: as sodium molybdate, phisphorylated castor oil, ammonium polyphosphate and ultrafine zinc borate are added, the wood flame retardant achieves an excellent effect.
Description
technical field [0001] The invention relates to the field of flame retardants, in particular to a clean and pollution-free wood flame retardant. Background technique [0002] Wood flame retardants are additives that prevent wood from being ignited and inhibit the spread of flames. With a wide range of uses, wood is a porous and complex natural organic substance mainly composed of cellulose, hemicellulose and lignin. Its characteristics are: it does not dissolve or melt under normal processing and use conditions, so the processing method is different from synthetic polymers; wood molecules contain a large number of oxygen-containing polar groups such as hydroxyl and hydroxymethyl groups, so they have strong hygroscopicity. , Poor dimensional stability; in addition to being flammable, it is also easy to rot and chemically degrade. The above-mentioned characteristics of wood determine that the mainstream varieties of wood flame retardants are all water-soluble products, and t...
