摘要 用硫酸和苯酚将杉木液化,采用傅立叶变换红外光谱和凝胶渗透色谱技术对液化产物进行了分析,并对用液化产物代替苯酚制备PF树脂的工艺进行了探讨。研究结果表明:杉木液化产物中含有大量的具有苯环结构的小分子活性物质,分子量主要分布在800~2 300之2;原料配比、树脂化温度、升温方式和残渣率等因素对PF树脂的质量有明显影响,采用优化工艺制备的PF树脂的游离酚和游离醛的含量分别为0.5%和0.3%,且胶合性能优良。 China fir was liquefied with phenol and sulfuric acid.Liquefaction products were analyzed with FT-IR(Fourier Transform Infrared Spectrometer)and GPC(Gel Permeation Chromatography).The results showed there were a lot of active small molecule substances with benzene ring structure in the liquefaction products,the molecular weight distribution range was from 800 to 2300.Effects of molar ratio of materials, temperature of resinification,heating modes and residue rate were discussed.The PF resin prepared from liquefaction products which was substituted for phenol had lower free phenol content(0.5%) and free formaldehyde content(0.3%),and had good gluing property.
