Abstract: A series of studies on fire_retardant particleboard at home and abroad are expounded comprehensively, including the theory of combustion of particleboard; the fireretardant mechanism of retard; the retard of particleboard; the technological process of fireretardant treatment and the test method of fireretardant effects. Moreover, the development of fireretardant particleboard is introduced and the countermeasures are put forward.
