  • Process for preparing copper-film-plated steel cord for vehicle tire
    Patent number: 6410098
    Abstract: A process is disclosed for preparing copper-film-plated steel cord suitable for use in vehicle tires comprising plating zinc or tin on the surface of steel cord, drawing the zinc or tin-plated cord, and then plating copper film onto the zinc or tin plated steel cord by contact with a solution of cupric sulfate solution, cupric nitrate, cupric chloride or cupric acetate. Compared with the presently used brass-plated steel cord, manufacturing tires with copper-plated cord according to the present invention reduces manufacturing time due to faster formation of adhesion interphase, increases the storage period by enhancing moisture stability, and retards adhesion degradation thereby extending the service life of the tires.
