【摘要】 采用非等温DSC技术分析了不同升温速率下硼改性酚醛树脂的固化行为,运用Kissinger和Ozawa方法对其固化反应动力学进行了研究,得到了固化反应活化能。结果表明,硼可以加速酚醛树脂的固化反应,使酚醛树脂的固化峰温度向低温方向移动,降低了酚醛树脂固化反应的活化能,使固化反应易于进行。更多还原

【Abstract】 Differential Scanning Calorimetry(DSC) was employed to study the curing behavior of boron modified phenolic resin.The curing kinetics was analyzed by using Kissinger and Ozawa method to obtain the activation energy for the curing reaction.It is shown that the curing reaction rate of the phenolic resin increases and the activation energy decreases after the addition of boron.更多还原
