Abstract:  In the paper, the physical-mechanical and flame resistant properties of fire-retardant particleboard affected by the two main manufacture factors of fire retardant content and resin content had been studied. The results showed that the physical-mechanical property of fire- retardant particleboard was hardly affected by FRWfire retardant. And all physical-mechanical indexes of it reached the demand of GB 4897-2015, Particleboard. On the contrary, the fire- retardant property of particleboard was affected apparently by fire retardant content. There were consanguineous linear correlative relationship between the oxygen index and fire retardant content. As the amount of resin content increased, the static flexural strength and internal bonding strength of the fire- retardant particleboard increased, and the expansion rate of the water absorption thickness decreased. The correlation was close. 

Key words:  fire retardant content, resin content, fire- retardant particleboard, physical-mechanical property, fire-retardant property
