| 摘 要： | 采用非等温差热分析(DTA)研究了竹粉(PB)对液化竹基酚醛树脂(PBF)固化行为及固化动力学的影响,求出固化反应的表观活化能、反应级数及频率因子等参数,进而建立了复合体系的固化反应动力学模型。实验结果表明:加入竹粉后,体系的固化峰顶温度、表观活化能、反应级数和频率因子分别降低至110.5℃、57.27kJ.mol-1、1.0079、1.99×105 s-1(纯PBF树脂的上述指标分别为122.5℃、63.46 kJ.mol-1,1.0173和8.04×105 s-1),竹粉的加入加速了PBF的固化反应过程。

| Abstract: | The effects of bamboo power(PB)on curing behaviors and kinetic of liquified bamboo-based phenolic resin(PBF) were invstigated by DTA technology.The apparent activation energy,reaction orders and the frequency factor of the curing reaction were calculated and finally the kinetic equation of of PBF/PB system was established.The results showed that peak temperature,activation energy,reaction order and frequency factor of the PBF/PB system were decreased to 110.5 ℃,57.27 kJ·mol-1,1.0079 and 1.99×105 s-1 respectively compared that of the pure PBF resin 122.5 ℃,63.46 kJ·mol-1,1.0173 and 8.04×105 s-1.The addition of bamboo power accelerated the curing process of PBF. |
