摘要

采用非等温DSC方法研究结晶液体杜仲胶(cLEUG)和非晶液体杜仲胶(aLEUG)对环氧树脂E-51/聚酰胺650(PA650)体系的固化反应动力学的影响。采用Starink法确定E-51/PA650、E-51/cLEUG/PA650和E-51/aLEUG/PA650三体系的非等温过程的动力学参数,确立3个体系的固化反应动力学方程,并与实验数据进行对比。结果表明,液体杜仲胶(LEUG)与E-51发生了共固化反应,LEUG的加入降低了E-51/PA650固化反应的表观活化能(E a),促进了固化反应的发生。E-51/cLEUG/PA650体系E a随着转化率的增加而增加;E-51/aLEUG/PA650体系E a则随着转化率的增加而降低。体系的黏度以及液体杜仲胶链中环氧基团的数目和活性是影响固化反应动力学的原因。Starink法确立的自催化反应模型方程适用于描述E-51/LEUG固化反应动力学。

Abstract

The influence of crystalline liquid Eucommia ulmoides gum (cLEUG) and amorphous liquid Eucommia ulmoides gum (aLEUG) on the curing kinetics of epoxy resin E-51/polyamide 650 (PA650) systems was studied by a non-isothermal DSC method. The kinetic parameters of the non-isothermal processes for the three systems of E-51/PA650, E-51/cLEUG/PA650, and E-51/aLEUG/PA650 were determined using the Starink method. The kinetic equations for the curing reactions of the three systems were established and compared with experimental data. The results showed that the liquid Eucommia ulmoides gum (LEUG) co-cured with E-51, and the addition of LEUG reduced the apparent activation energy (Ea ) of the curing reaction of E-51/PA650, promoting the occurrence of the curing reaction. The Ea of E-51/cLEUG/PA650 system increased with the increase of conversion, while the Ea of E-51/aLEUG/PA650 system decreased with the increase of conversion. The viscosity of the system and the number and activity of epoxy groups on the LEUG chain are the reasons that affect the curing reaction kinetics. The self-catalytic reaction model equation established by Starink method is suitable for describing the kinetics of E-51/LEUG curing reaction.
