用自由体积的概念,建立化学流变学模型,以预测不饱和聚酯树脂固化过程中的粘度变化。即预测作为固化时间函数的固化度的固化动力学机械动力模型,机械动力模型采用考虑到固化反应受扩散控制的自由基聚合的近似计算法。为了试验所建立的化学流变学模型的实用性。用通用型不饱和聚酯树脂进行了固化实验,并检测了树脂试样固化时的粘度。进行的
Using the concept of free volume, a chemical rheology model was established to predict the viscosity change of the unsaturated polyester resin during the curing process. Ie, a cure kinetic mechanical dynamic model that predicts the degree of cure as a function of cure time and a mechanical dynamical model that employs an approximate calculation that takes into account the free radical polymerization controlled by the cure reaction. In order to test the practicality of the established chemical rheology model. The curing experiment was conducted with general-purpose unsaturated polyester resin, and the viscosity of the resin sample during curing was examined. ongoing
