| Abstract: | A new heat-resistant epoxy dripping impregnating varnish modified by filler was prepared.The effect of dispersion process on the anti-sedimentation property of the varnish was studied,and the effects of various high temperature resistance curing agents on the thermal,mechanical and electrical properties of the varnish were compared.The results show that the dripping impregnating varnish has advantages of high heat distortion temperature and high adhesive strength.The glass-transition temperature and heat conductivity attain 180 ℃ and 0.3 W/(m.K) respectively.Moreover,the varnish has good anti-sedimentation property. |
