木材阻燃剂SLB处理木材的阻燃性能研究

Study on the Fire-Retardant Properties of the Treated Wood with SLB Fire-Retardant

选用新型木材阻燃剂SLB对马尾松和南洋楹两种木材进行了阻燃处理,并用氧指数法和木垛法对处理后木材的阻燃性能进行了测试。结果表明:用SLB阻燃剂处理木材,载药量达到40 kg/m3以上时,阻燃性能达到相关标准的要求,阻燃效果随着载药量的增大而增强。在载药量相近时,南洋楹木材比马尾松木材的阻燃效果显著。

Pinus massoniana and Albizzia falcata was treated by the new product of SLB fire retardant. Meanwhile the fire-retardant properties had been measured in treated wood of SLB fire-retardant. The results showed that, when the wood retention more than 40 kg/m^3 , the fire-retardant properties of the treated wood matched the relevant standards, the more retention of SLB in wood, and the better fire-retardant properties of wood. In a similar retention,the fire-retardant properties of A. falcata timber better than the wood of P. massoniana.
