一种含硼木材防护剂SBB的阻燃性能研究

Flame Retardant Performance of the Boron-Contained Wood Preservative SBB

采用高含硼量、高溶解度的木材防护剂SBB与(NH4)2HPO4按不同配比进行木材阻燃处理试验,结果表明:单一药剂处理时,(NH4)2HPO4阻燃效果略优于SBB;(NH4)2HPO4和SBB同时作用,形成具协同效应的阻燃体系,提高了阻燃效果;m[(NH4)2HPO4]∶m(SBB)=1∶3且混合物的质量分数为10%的处理为最优方案.

Fire retardant performance of high boron-contained, high solubility wood preservative SBB and （NH4） 2HPO4 were studied and different ratios of the two chemicals were evaluated. The results showed that the fire retardant performance of （NH4）2HPO4 was better than that of SBB preservative. The synergetic effect of （NH4 ）2HPO4 and SBB improved fire retardant performance. The optimal mass ratio of （NH4）2HPO4 and SBB was 1：3（ω = 10%）.
