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

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/m^3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，其用药理根据板材的厚度进行了初步确定，剂量范围为３０－９０kg/m^3。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按拉１０％。ＦＲ－１处理的马尾松、毛白杨、吸药量分别为７５．６及９３．５kg/m^3时，吸水至饱和时，木材抗湿胀率（antiswelling ef-ficacy,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/m^3时，ＡＳＥ分别为４６．２％、４１．４％。各处理对抗弯弹性模具（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。

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

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.
