WIPO Patent Application WO/2022/044358
Kind Code:
A1
Abstract:
This resin production method is for producing a resin with which an insulating structure formed at an outer periphery of a conductive body is impregnated, the method comprising: a filler-mixing step for mixing a nano-filler with an epoxy resin such that the proportion of the nano-filler is at least 15 wt% to produce a mixture; a shear-mixing step for shear-mixing the mixture; a diluent-mixing step for mixing, to the mixture after the shear-mixing step, a reactive diluent that reduces the viscosity of the epoxy resin; and a curing agent-mixing step for mixing an acid anhydride curing agent to the mixture after the diluent-mixing step.
