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

         

摘要

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10%。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(an tiswelling efficacy,ASE)分别为30%、46%;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46.2%、41.4%。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10.6%及17.9%。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,dime nsional 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 in dex (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 ret ention.Anti-swelling effectiveness (ASE) of Pinus massoniana and Populus tomentosa treated with FR-1was 30.0 % and 46.0 % respectively at the retentio n 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 k g/m3 respectively according to Chinese national standard GB1934.2-91.MOE of Pinus massoniana treated with FR-1 was not significantly changed,however MO E of Populus tomentosa treated with FR-1 increased 6.1%.MOE of Pinus mass oniana and Populus tomentosa treated with PF resin increased 10.6 % and 17 .9 % respectively.MOR of both Pinus massoniana and Populus tomentosa tre ated with FR-1 was not significantly changed.
