METHOD OF PREPARATION OF NICKEL FILLER FOR PRODUCTION OF CURRENT-CONDUCTING ADHESIVE COMPOSITION ON BASE OF EPOXY DIANE RESIN

摘要

FIELD: preparation of nickel filler for production of current-conducting composition on base of epoxy diane resin ЭД-20 for shielding and contacting of metal surfaces.;SUBSTANCE: proposed method includes drying of nickel powder ПНК-1Л5 which is immersed in alcohol-nephrase mixture before drying at alcohol-to-nephrase ratio of 1:1 and is mixed for 5-10 minutes at temperature of 25±10°C ; drying is first performed at temperature of 25±10°C continued for an hour and then at temperature of 100±10°C continued for 3-5 hours; then, mixture is cooled down to temperature of 25±10°C.;EFFECT: reduction of specific volume resistance of current-conducting adhesive composition.
