At present, a large number of wood-based panels are used for flooring and building decoration. When a building fires, wood-based panels burn and emit a large amount of heat, making the flame spread rapidly, causing a large number of casualties and major economic losses. Therefore, a large number of combustible and flammable wood-based panels used in the interior decoration of buildings are potential fire hazards. China stipulates that the use of wood-based panels in high-rise buildings must undergo flame retardant treatment. Flame retardant board is a special kind of man-made board. At present, the mainstream flame retardant board products on the market include flame retardant density board and flame retardant plywood. Flame retardant board has stable chemical properties, high ignition point and corrosion resistance. In the production process of flame retardant board, some manufacturing processes can be used to integrate flame retardant into the board, so it has good flame retardancy. At present, flame-retardant panels are rarely used in ordinary household decoration, and most of them are used in public building projects. The flame retardant panel has a high ignition point, which can effectively control the fire process and reduce smoke and toxic gas in case of fire. With the continuous improvement of consumers' awareness of fire safety, the demand for flame retardant board market is increasing year by year, with broad market development prospects. As the main material of wood floor, furniture, and interior decoration in China, the output and demand of ordinary plywood are increasing rapidly. This paper introduces the classification and flame retardant principle of wood-based panels, analyzes the commonly used wood flame retardants and flame retardant treatment methods, and forecasts the future development trend of flame retardants and flame retardant technology, in order to better promote the rapid development of the domestic wood-based panel industry.
