METHOD OF PREPARATION OF NICKEL FILLER FOR PRODUCTION OF CURRENT-CONDUCTING ADHESIVE COMPOSITION ON BASE OF EPOXY DIANE RESIN Russian patent published in 2007 - IPC C09C1/62 C09C3/08 C09J9/02 C09J163/02 C22F1/10 

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.
