A Brief Description Of Wood Flame Retardant

Wood is a porous and complex natural organic material 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 hydroxyl and hydroxymethyl and other oxygen-containing polar groups, so they have strong hygroscopicity , Poor dimensional stability; besides being flammable, it still has the characteristics of being perishable and chemically degradable. The above-mentioned characteristics of wood determine that the mainstream varieties of wood fire retardants are all water-solvent products, and the dominant addition method is the impregnation method.
