EPOXY RESIN COMPOSITION FOR ELECTRIC POWER PART AND EPOXY RESIN PART FOR POWER CABLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To suppress the sedimentation of a filler caused in a cured epoxy resin and provide a uniform layer without forming a mechanical weak point part. ;SOLUTION: This epoxy resin composition for electric power parts is obtained by adding 10-50 pts.wt. curing agent, 10-300 pts.wt. filler and 10-200 pts.wt. another filler comprising fine spherical fillers having 0.1-10μm respective diameters to 100 pts.wt. epoxy resin, heating the resultant mixture and then curing the heated mixture. The epoxy resin composition is capable of suppressing the sedimentation of the fillers without forming a mechanical weak point part. The epoxy resin composition for the electric power parts is injected into a desired metallic mold and molded to thereby afford an epoxy resin part for power cables uniform in mechanical strength and thermal characteristics, etc.;COPYRIGHT: (C)1997,JPO
