Wood flame retardant mechanism covering theory, thermal theory, non-combustible gas to dilute theory, the theory of free radical trapping, the increase in carbon content and volatiles to reduce the theor y; wood-based panels fire retardant treatment additive flame retardant in the production process and into the board deal with two methods, high pressure processing method is the most important industrialized; FRW fire retardant, the BL-environmentally friendly flame retardant phosphorus - nitrogen - boron flame retardants are still the mainstream of the wood flame retardants. Flame retardant for wood plastic composites is still in its infancy, the general means of flame-retardant wpc wood fiber and matrix, respectively; the development of highly efficient intumescent wood flame retardants and nanotechnology applied to the wood fire retardant manufacturing, the development of flame-retardant high efficiency, multi-functional composite flame retardant low smoke, low toxicity, environmentally friendly flame retardant research developments in the field direction in the future.
