摘要:The technique for preparing phenol formaldehyde resin from phenolated wood (PWF) and its characters were studied and analyzed. Poplar (Populus spp.) wood meal was liquefied by phenol in the presence of sulfuric acid as a catalyst. After the liquefied products were cooled, alkaline catalyst and formaldehyde were added. The mixture was kept at (60?) C for 1h and then was heated to (85?) C for 1h. The influence of molar ratio of formaldehyde to phenol (F/P) was investigated. The results showed when the molar ratio of formaldehyde to phenol was over 1.8, the PWF adhesives had high bond quality, bond durability and extremely low aldehydes emissions.
本文研究了用酚化木材制备酚醛树脂的技术,并对其性能进行分析。在硫酸催化作用下,用苯酚对中国人工林杨树木粉进行液化。待液化产物冷却后,加入一定量的碱性催化剂和福尔马林,在(60?2)C下1小时,然后升温至(85?2)C继续反应1小时,冷却。同时观察了甲醛与苯酚的配比对树脂性能的影响。结果表明当甲醛与苯酚的摩尔比超过1.8时,用酚化木材制备的酚醛树脂具备较高的胶合强度和很强的胶合耐久性,并具有极低的醛类释放量。图4参13。
