摘　　要：以万能力学试验机、氧指数测定仪和烟密度仪检测添加阻燃剂和抑烟剂的中密度纤维板的力学性能和燃烧性能。结果表明:阻燃剂和抑烟剂会降低中密度纤维板的力学性能,每增加2%的量,中密度纤维板的力学性能就会下降2%～12%;阻燃剂在提高纤维板阻燃性能的同时会有效的降低其燃烧烟密度,每增加2%的阻燃剂,纤维板的氧指数增加2%～7%,燃烧烟密度降低9%～29%;纤维板的抑烟效果随着抑烟剂的增加而提升,每增加2%的抑烟剂,烟密度就会减少5%～15%。The mechanical and burning property of MDF which added the fire retardant and smoke suppression were tested with Mechanical machine, Limit Oxygen Index and Smoke testing apparatus. The result show that： the fire retardant and smoke suppression can weaken the mechanical property of MDF. Every 2% increment of fire retardant and smoke suppression coupled with 2%～12% inducement of mechanical strength of MDF; The fire retardant addition can reinforce the fire-retardancy property and lowed the smoke generation of MDF, every 2% increment of fire retardant coupled with 2%～7% increment of Limit Oxygen Index and 9%～29% inducement of smoke generation.The effect of smoke suppress of MDF is promoted with the smoke suppression increment, every 2% increment of smoke suppression coupled with 5%～15% inducement of smoke generation.
