摘　　要：由单纯液体的粘度预测混合液体的粘度,具有流变学理论研究和工业应用价值.传统的预测方程利用各组分的粘度,分别从质量分数和摩尔分数的角度进行预测,实验发现传统方程在预测时误差较大.在前人方程的基础上,从分子结构的角度,引入溶度参数、范德华体积和活化能等参数修正摩尔分数,得到了一些新方程,并将各方程的计算值与实验值进行了比较.研究表明：用范德华体积和活化能共同修正所得的方程的计算值平均相对误差最小,仅为4.99%~7.60%,而且在预测有较复杂分子结构组分的混合物时体现了较大的优势,平均相对误差为1.12%.It is significative to predict the viscosity of liquid mixture with the viscosity of the pure components in theoretical research of rheology and its industrial application.Traditional equations for predicting the blend viscosity use the viscosity of each component and their mass fraction or molar fraction.The experiment indicates that the traditional equations are not accurate enough.By introducing a set of parameters,to the formal equations,such as solubility,van der Waals＇ volume,activation energy,and then modifying the molar fractions in the view of molecular structure,we get some new equations.Comparing the experimental values to the calculated ones with the new equations,we find that the average relative error is small,only 4.99%~7.60%.In addition,the new equation has the advantage of being able to predict the viscosity of the mixture with complicated molecular structure components.
