摘要
以TPU(热塑性聚氨酯弹性体)和ABS(丙烯腈-丁二烯-苯乙烯嵌段共聚物)为主要原料,采用熔融共混法制备了TPU/ABS复合材料。应用DSC(差示扫描量热)法分析了TPU/ABS复合材料的固化反应过程,并采用Kissinger方程和Crane方程计算出体系固化反应的动力学参数[如表观活化能(ΔE)、反应级数(n)和指前因子(Ak)等],进而得到相关的动力学模型函数。研究结果表明:体系固化反应的ΔE=85.3 k J/mol、n=0.762和Ak=1.9×10^(11),并且TPU/ABS复合材料的固化动力学模型机理函数符合双参数反应动力学模型。
With TPU （thermoplastic polyurethane elastomer） and ABS （ acrylonitrile-butadiene-styrene block copolymer） as main raw materials, a TPU/ABS composite was prepared by melt blending method. The curing reaction process of TPU/ABS composite was analysed by DSC （differential scanning calorimetry）, and the kinetics parameters[such as apparent activation energy （AE）, reaction order（n） and pre-exponential factor （Ak）] of curing reaction of system were calculated by Kissinger equation and Crane equation, and then the relevant kinetics model function was obtained. The research results showed that the AE,n and Akof curing reaction of system were 85.3 kJ/mol, 0.762 and 1.9 × 10 11 respectively, and the mechanism function of curing kinetics model for TPU/ABS composite can meet the kinetics model of both parameter reaction.
