摘　　要：采用非等温DSC法对M型苯并恶嗪(MBOZ)固化动力学进行了研究。分别通过n级反应模型和自催化模型求解出反应动力学参数,进而得到固化反应动力学模型。结果表明,n级反应模型与实验值的差别较大;而采用自催化模型得到的曲线与实验得到的DSC曲线吻合较好,所确立的模型在5～15 K/min的升温速率下能较好地描述MBOZ的固化反应过程,并为其树脂基复合材料工艺优化条件提供了理论依据。The curing kinetics of M type benzoxazine（MBOZ） monomer was studied by nonisothermal methods.The curing kinetic parameters was calculated using n order reaction model and the autocatalytic model,respectively and then the curing kinetics model was determined.The results indicated that there was a great different between the values from n order model and the experimental datas.The DSC curves from the autocatalytic model were in good agreement with the experimental curves.The model established could describe the curing reaction process of MBOZ well at the heating rate of 5~15 K/min and provided a theoretical basis for the optimization of process conditions of composites with MBOZ resin matrix.
