苯酚-尿素-乙二醛树脂的合成工艺研究
|
摘要
为从根本上消除木材胶合制品的甲醛释放对环境和人体健康的危害及改善尿素-乙二醛(UG)树脂的性能,选择无毒、低挥发的乙二醛代替甲醛,与尿素、苯酚反应制备苯酚-尿素-乙二醛(PUG)共缩聚树脂木材胶黏剂。研究了在反应的不同阶段加入苯酚以及苯酚的加入量对树脂性能的影响,并通过傅里叶变换红外光谱法(FTIR)对树脂的结构进行了表征。结果表明:在所研究的合成条件下,PUG树脂的pH和状态受苯酚加入量和加入时间的影响不大,苯酚的加入量为尿素总量的10%为宜;树脂中主要含有氮氢(N—H)、氧氢(O—H)、羰基(C=O)、饱和碳氢(C—H)、醚键(C—O—C)及碳氮(C—N)键等主要官能团。
in order to fundamentally eliminate the harm of formaldehyde release from wood adhesive products to environment and human health and improve the properties of urea-Glyoxal(UG) resin, nontoxic and low volatile Glyoxal was selected to replace formaldehyde and urea. The wood adhesive of phenol-urea-Glyoxal( PUG) co-Polycondensation resin was prepared by phenol reaction. The effects of adding phenol and the amount of phenol on the properties of the resin were studied. The structure of the resin was characterized by Fourier transform infrared spectroscopy(FTIR). The results showed that the pH and state of PUG resin were affected by phenol under the synthetic conditions studied. The addition amount of phenol is 10% of the total amount of urea, and the addition amount of phenol is 10% of the total amount of urea. The resin mainly contains nitrogen and hydrogen(N—H), oxygen hydrogen(O—H),carbonyl group( C—O), saturated hydrocarbon( C—H), ether bond( C—O—C) and carbon nitrogen(C—N) bond.
