摘　　要：采用差热分析(DTA)技术,对间苯二酚共聚液化竹基酚醛树脂的固化特性和固化动力学进行了研究。实验结果表明,间苯二酚的加入加速了液化竹基酚醛树脂的固化反应,树脂固化反应的表观活化能、反应级数、频率因子均随间苯二酚含量的增加(间苯二酚占液化竹基酚醛树脂的质量百分比依次为0%、1%、3%、5%)而逐渐减小,利用外推法求出的静态(β=0℃/min)的特征固化温度Ti、Tp和Tf也均逐渐降低。此外,还建立了不同含量的间苯二酚共聚液化竹基酚醛树脂的固化反应动力学模型。The curing behavior and kinetics of bamboo liquefaction phenolic resin with different contents of resorcinol was studied by DTA technology. The results showed that the addition of resorcinol accelerated the curing reaction of bamboo liquefaction phenolic resin, with the increase of the content of resorcinol （0%, 1%, 3%, 5%）, the apparent activation energy, reaction order and frequency factor all gradually decreased during the coring process, and the static （β=0℃/min） characteristics curing temperatures Ti,Tp and Tf calculated by extrapolation method were also all decreased. The curing kinetics model of bamboo liquefaction phenolic resin with various contents of resoreinol was bulit.
