Abstract: To confirm the influence of different wooden materials and inflaming retarding agents on the properties of particleboard panel and manufacture the fire-retarding particleboard panel with better properties for reducing the harm due to the fire indoor. Influences of five kinds of fire-retarding agents(FR-A, FR-B, FR-C, FR-D and FR-E)and their different added amount(6%, 8%, 10% and 12%)and two kinds of wooden materials(wooden particles and hemp-shiv particles)on the physical properties, mechanical properties and inflaming properties of the particleboard panels were investigated to provide the information for manufacturing particle board panels with better inflaming retarding properties. The results showed that the fire-retarding agents, additive amount and wooden materials all had great influences on the physical, mechanical and inflaming properties of particle board panels. The fire-retarding agents had disadvantageous influence on the physical and mechanical properties of particle panels and those were worse with the additive amount of fire-retarding agents increasing from 6% to 12%. Besides, as the additive amount of fire-retarding agents increased, the oxygen index(OI)increased and the smoking density grade(SDR)reduced, furthermore the OI and SDR of hemp-shiv based particle panels were lower than those of wood based particle panels. Besides, the FR-A and FR-B of fire-retarding agents were good to make inflaming retardant hemp shiv-based particle board panels while the FR-C, FR-D and FR-E of fire-retarding agents were good to make inflaming retardant wood-based particle board panels. In a word, the physical, mechanical and inflaming retardant properties of particle board were mainly depended on the characters of raw materials and fire-retarding agents and it should be studied furthermore in future.
