N,N-4′,4′-二苯甲烷双马来酰亚胺/1,6-己二醇二丙烯酸酯的紫外光固化研究

RESEARCH ON UV-PHOTO CURING OF N,N′-BISMALEIMIDO-4,4′-DIPHENYLMETHANE WITH 1,6-HEXANEDIOLDIACRYLATE

制备了N,N-′4,4′-二苯甲烷双马来酰亚胺(BDM)/1,6-己二醇二丙烯酸酯(HDDA)体系,探讨了BDM/HDDA体系实现UV固化的条件,研究了引发剂种类及其含量对BDM/HDDA体系光固化的反应性及热稳定性的影响。研究表明,2,4,6-三甲基苯甲酰基-二苯基氧化磷(TPO)的综合引发效果要好于同类引发剂安息香乙醚和提氢型光引发剂二苯甲酮-三乙醇胺体系。

N, N′- bismaleimido- 4,4′- diphenylmethane （BDM）/1,6-hexanedioldiacrylate （HDDA） system was designed and prepared, and the conditions for achieving the photocuring of BDM/HDDA system was discussed. The influence of the type and content of photo-initiator on the photo-curing reactivity and thermal stability of BDM/HDDA system were mainly investigated. Results showed that the integrated effects of TPO were better than benzoin ethyl ether and benzophenone-tertiary amine system.
