摘要:
聚脲（polyurea， PUA）性能优异，在工业建筑、石油化工和海洋设施等领域具有广泛应用，但过快的PUA合成反应速度使得难以用传统方法测定PUA反应动力学．为解决这一问题，以甲苯二异氰酸酯（toluene diisocyanate， TDI）和三乙烯四胺（triethylenetetramine， TETA）为单体，通过反应过程中pH值的变化，采用pH数值模拟法建立数学模型求解聚脲反应动力学参数，并用傅里叶变换红外光谱（Fourier transform infrared spectroscopy， FTIR）法验证．pH数值模拟法操作简便，结果表明，利用pH数值模拟法测得的聚脲反应活化能为78 kJ/mol，FTIR法计算的反应活化能为88 kJ/mol，两种方法得到的活化能相近．说明pH数值模拟法快速测量动力学参数具有可行性和可靠性.
Abstract:
Polyurea is widely applied in various fields, including industrial buildings, petrochemicals and marine facilities, due to its excellent performance, but an excessively fast synthesis reaction makes it difficult to determine the kinetics of polyurea microcapsules by tranditional methods. To solve this problem, a mathematical model is developed by a pH numerical simulation method to calculate the kinetics parameters of the polyurea reaction through the change of pH value in the reaction process of the monomers of toluene diisocyanate (TDI) and triethylenetetramine (TETA). Fourier transform infrared spectroscopy (FTIR) is used to confirm the kinetics parameters obtained in the mentioned calculations. The results show that the pH numerical simulation method is simple to measure. The activation energy is 78 kJ/mol measured by the pH numerical simulation method, which is close to 88 kJ/mol measured by FTIR. The small variation of the activation energies between the two methods shows that pH numerical simulation method is feasible and reliable for rapid measurement of kinetics parameters of the PUA reaction.
