flame retardantIt is one of the fastest growing varieties in all kinds of material additives. The purpose of the flame retardant is to make the non flame retardant material have flame retardant properties, and it is not easy to burn or self-extinguish under certain conditions. Wood flame retardant is a kind of flame retardant, with good thermal stability, non-volatile, less smoke, do not produce toxic and corrosive gases, low price and other characteristics, by the world's general attention. Wood flame retardants continue to develop, the third generation of resin-based wood flame retardants have been put into use, resin-based flame retardants help wood smoke annealing.

The third generation of wood flame retardant refers to the resin type flame retardant, which is made of urea formaldehyde resin, phenolic resin or melamine and inorganic flame retardant such as diammonium hydrogen phosphate and ammonium polyphosphate according to different flame retardant requirements. Compared with the first generation of inorganic flame retardants, the second generation of inorganic and organic flame retardants, the third generation of resin-based flame retardants have the least impact on the physical and mechanical properties of wood, and the moisture absorption is low. The flame retardant will not precipitate. The specific treatment method is to put the wood into a high-pressure tank, first vacuum, and then pressurize the flame retardant into the wood. After the wood is impregnated with the flame retardant, the resin is cured during the drying process, and the inorganic flame retardant that is easy to lose in the formula is coated and fixed, thereby improving the anti-loss, migration and moisture absorption of the flame retardant. Wood flame retardant in the future will be further towards ultra-fine, nano, organic-inorganic composite, low toxicity, smoke suppression development.

With the rapid development of the real estate industry and the increasing number of public places,90%The above wood products are used for interior decoration and furniture manufacturing. Since wood is one of the main igniters of fire, in accordance with mandatory national standardsGB20286-2006According to the requirements and identification of combustion performance of flame retardant products in public places, wood products used in public places must meet the corresponding flame retardant standard grade, so wood flame retardant technology has attracted much attention. At present, the proportion of flame retardant wood products in China is far less10%The developed countries account15%～20%The development potential of wood flame retardants in China is huge.
