Adding flame retardants during production process and finished-panel treatment are the two major fire retardant treatments of artificial panel, and pressurization is the most important industrialized method at present. Flame retardants with N-P-B represented by flame retardant FRW and BL- environmental protection flame retardant are still the main stream. Research on wood-plastic composite flame retardance is still in an embryonic stage, and wood fiber and matrix are always treated respectively.
