Abstract

The invention relates to an anhydride-free molecular distilled epoxy VPI (vacuum pressure impregnation) impregnated resin and a preparation method thereof. The anhydride-free molecular distilled epoxy VPI impregnated resin is prepared from molecular distilled epoxy resin, active diluting agent, curing agent and auxiliaries, wherein the active diluting agent is a cycloaliphatic epoxy active diluting agent, the curing agent is complex formed by salt of metal organic carboxylate and acetylacetone metal salt, and amine substances of boron-amine complex, triethanolamine and dimethyl benzylamine. The VPI impregnated resin cannot be easily damped, can be stored stably, has good electrical and mechanical performances, particularly has tiny thermal state dielectric loss factor, is equivalent to the performance of epoxy anhydride resin, and is a perfect substitute good of the epoxy anhydride VPI impregnated resin.

Description

technical field

[0001] The invention relates to impregnating resin materials for motor insulation, in particular to an anhydride-free molecular distillation epoxy VPI impregnating resin and a preparation method thereof. The novel epoxy VPI impregnating resin can be used in the manufacture of high-voltage motors, generators, and the like. Background technique

[0002] The vacuum pressure impregnation (VPI) process is the most advanced insulation impregnation treatment technology in the world today. It can be used to manufacture air gap-free insulation, so that the coil insulation components have good continuity and thermal conductivity, and excellent moisture resistance, thereby improving the technical economy of the motor. indicators and operational reliability.

[0003] VPI impregnating resin is one of the key materials to realize vacuum pressure impregnation insulation treatment process. At present, there are three types of VPI impregnating resins mainly used at home and ...
