FR-1、FR-2及PF树脂对木材阻燃、防腐、尺寸稳定等效果的研究

STUDY ON THE FIRE AND ROT RESISTANCE AS WELL AS DIMENSIONAL STABILITY OF WOOD TREATED WITH FR-1,FR-2 AND PF RESIN

功能性改良药剂FR 1、FR 2及PF树脂处理马尾松、毛白杨后对木材阻燃、防腐、尺寸稳定及MOE/MOR的研究结果表明 ,FR 1处理的马尾松吸药量为 34 5kg/m3 时 ,氧指数可达 61 %。FR 1处理的马尾松、毛白杨达到阻燃标准时 ,其用药量根据板材的厚度进行了初步确定 ,剂量范围为 30～ 90kg/m3。FR 1及FR 2在达到阻燃用药量的同时 ,处理后的马尾松、毛白杨耐腐试验的重量损失率小于或接近 1 0 %。FR 1处理的马尾松、毛白杨 ,吸药量分别为 75 6及 93 5kg/m3 时 ,吸水至饱和时 ,木材抗湿胀率 (antiswellingef ficacy,ASE)分别为 30 %、4 6% ;PF树脂处理的马尾松、毛白杨 ,吸药量分别为 79 0、63 8kg/m3 时 ,ASE分别为 4 6 2 %、4 1 4 %。各处理对抗弯弹性模量 (MOE)影响为 ,FR 1处理的马尾松 ,MOE差异不明显 ,FR 1处理的毛白杨 ,MOE增加幅度为 6 1 % ,PF树脂处理的马尾松、毛白杨 ,MOE增加幅度分别为 1 0 6%及1 7 9%。FR 1处理的马尾松、毛白杨对抗弯强度 (MOR)影响不明显。

The effectiveness of fire resistance,rot resistance,dimensional stability as well as MOE/MOR of masson pine and poplar treated with FR-1,FR-2 and PF resin was briefly conducted in this article.The limited oxygen index (LOI) of masson pine treated with FR-1 was 61% at the retention of 34.5 kg/m3.The retention of which meet fire test standard GB8625-88 was defined to 30～90 kg/m3 according to wood species and thickness of timber.Weight losses of treated masson pine and poplar were under or about 10% at the fire resistant retention.Anti\|swelling effectiveness (ASE) of Pinus massoniana and Populus tomentosa treated with FR-1was 30.0 % and 46.0 % respectively at the retention of 75.6 and 93.5 kg/m3.ASE of Pinus massoniana and Populus tomentosa treated with PF resin was 46.2 % and 41.4 % at the retention of 79.0 and 63.8 kg/m3 respectively according to Chinese national standard GB1934.2\|91.MOE of Pinus massoniana treated with FR\|1 was not significantly changed,however MOE of Populus tomentosa treated with FR-1 increased 6.1%.MOE of Pinus massoniana and Populus tomentosa treated with PF resin increased 10.6 % and 17.9 % respectively.MOR of both Pinus massoniana and Populus tomentosa treated with FR\|1 was not significantly changed.
