根据扩散控制反应的基本原理 ,建立了合适的反应模型 ,描述了 4 ,4′ 二 ( 2 ,3 环氧丙氧基 )偶氮苯(DGEAP) / 4,4′ 二氨基二苯甲烷 (DDM)环氧树脂的固化行为 .该模型认为 ,随着环氧基团反应程度的提高 ,基团的反应半径将受到影响 .当体系中出现了介晶基元的有序排列时 ,与之相连的反应基团的分布也受到影响 ,有序区内的局部浓度将变大 ,产生假浓度效应 ,并最终影响扩散控制反应动力学 .通过与普通环氧树脂固化动力学的比较 ,证实了这一效应 .
According to the basic principle of diffusion controlled reaction, a suitable reaction model was established and the effects of 4, 4 ’bis (2,3-epoxypropoxy) azobenzene (DGEAP) / 4,4’diaminodiphenylmethane ) Epoxy resin curing behavior of the model that, as the degree of reaction of epoxy groups increased, the reaction radius of the group will be affected when the system appears in the orderly arrangement of mesogen, with which connected The distribution of the reactive groups is also affected, the local concentration will increase the orderly region, resulting in false concentration effect, and ultimately affect the proliferation control reaction kinetics. By comparison with the curing kinetics of ordinary epoxy resin, which confirmed this One effect.
