Abstract

Scholars in the electrical field hope to use catalysts to improve the curing system of acid anhydride epoxy insulating materials, so as to solve the problem that a large number of waste insulating materials can not be effectively recycled. One of the most important research directions is to select a suitable catalyst to realize the recovery of epoxy by hot pressing. Therefore, we prepared epoxy samples based on the published triethanolamine catalytic anhydride cured epoxy formula. Then, hot pressing recovery tests were carried out at 180, 200, 220 and 240℃ to test the insulating properties of the samples, and to study the changes of dielectric constant, dielectric loss and breakdown field strength with the hot pressing recovery temperature. The results show that with the increase of hot pressing recovery temperature, the dielectric constant of the sample increases, the dielectric loss decreases first and then increases, and the breakdown field strength increases first and then decreases. The insulation properties of the samples recovered by hot pressing at 200℃ are the best. Triethanolamine catalyzed anhydride curing epoxy can realize hot pressing recovery of insulating materials.
