摘要 |
A method for surface treating conductive copper powder comprises dispersing pure copper powder or silver-coated copper powder in a solution of coupling agent selected from the group consisting of silane, titanate, aluminate and zirconate and a ZB-3 treating agent which is the reaction products of peanut oil fatty acids, boric acid and triethanolamine in a molar ratio of 1:1:2 in an organic solvent, the total amount of the coupling agent and ZB-3 treating agent being controlled in the range of from 0.1% to 10%, based on the weight of the copper powder, filtering after 1 hour standing and drying at 40 DEG -60 DEG C. under vacuum.
