研究了以橡胶、木材纤维和废旧瓦楞纸箱为原料制成的中密度纤维板的阻燃性能。以三氢氧化铝（ATH）为阻燃剂，与纤维混合，采用湿法制备中密度纤维板实验材料。苯酚甲醛（PF）树脂溶液，按纤维干重2%的比例与0%、10%、15%和20%的ATH混合使用。采用极限氧指数（LOI）法进行阻燃试验。研究的其他性能包括内部粘结强度、厚度膨胀和吸水率。结果表明，随着MDF LOI的增加，ATH的负荷量也随之增加。结果表明，在充分加载的情况下，ATH可以提高中密度纤维板的阻燃性能。ATH浓度的增加使不加树脂的MDF的113值增加。不含树脂的中密度纤维板，随着废旧瓦楞容器纤维的回收成分的增加，其内部粘合度逐渐增加。树脂的加入提高了内部粘结强度，减少了厚度膨胀，并降低了吸水率。随着废旧瓦楞纸箱纤维回收成分的增加，板材厚度膨胀增大。扫描电镜（SEM）和x射线能谱分析（EDAX）显示纤维间空隙有ATH和树脂填充的迹象。(c) 2005 Elsevier Ltd版权所有。
The flame retardancy of medium density fiberboard (MDF) made from mixture of rubberwood fibers and recycled old corrugated containers was studied. Aluminum trihydroxide (ATH) was used as a fire retardant additive and mixed with the fibers to manufacture experimental MDF panels using wet process. Phenol formaldehyde (PF) resin in liquid, 2% based on oven dry weight of fibers, was used along with 0%, 10%, 15% and 20% of ATH. The flame retardant test was done using the limiting oxygen index (LOI) test. The other properties investigated include internal bond strength, thickness swelling and water absorption. The results showed that ATH loading increased as the LOI of MDF increased. This demonstrated that ATH could improved the fire retardant property of MDF at sufficient loading. An increase in concentration of ATH showed an increase in the 113 values of MDF made without resin. MDF panels made without resin showed a progressive increase in internal bond as the composition of recycled old corrugated containers fiber increased. Addition of resin improved internal bond strength and reduced thickness swelling, and water absorption. Thickness swelling of panel increased as the composition of recycled old corrugated containers fiber increased. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX) showed that there is indication of ATH and resin filling the void space in between fibers. (c) 2005 Elsevier Ltd.
