摘　　要：采用过氧化苯甲酰(BPO)与过氧化-2-乙基己酸叔丁酯(OT)组成复合引发体系,比较不同配比下的不饱和聚酯树脂(UPR)所制人造石英石的力学性能。应用差示扫描量热法(DSC)研究复合引发体系下UPR的不等温固化反应动力学性能,使用Kissinger方程及Crane方程对数据进行处理并得到UPR的固化动力学模型,并对所得模型加以验证和修正,修正后的模型与实验结果具有更好的一致性。The mechanical properties of synthetic quartz of unsaturated polyester resin are compared for different recipes of the complex initiation system. The initiation system consists of benzoyl peroxide（ BPO） and tert-butyl peroxy-2-ethylhexanoate（ OT）. The non-isothermal curing kinetics of the unsaturated polyester resin with complex initiation system was studied using differential scanning calorimetry（ DSC）. Kissinger and Crane equations are used to obtain the curing kinetics model of unsaturated polyester based on the experimental data obtained. Then,the model developed was verified and modified and better agreement with experiments was achieved.
