Process for preparing copper-film-plated steel cord for vehicle tire

摘要

The process for preparing copper-film-plated steel cord (hereafter abbreviated as copper-plated cord) of 20-90 nm of copper film for vehicle tire, by plating zinc or tin with strong tendency of ionization on the surface of steel cord and after drawing the zinc or tin-plated cord, and then plating copper film onto it contacting with cupric sulfate solution of 10 to 50 gram per litter. Compared with the presently used brass-plated steel cord, manufacturing tires with copper-plated cord described in the invention enables to reduce manufacturing time of tires due to its faster formation of adhesion interphase, to increase storage period by enhancing the stability against moisture, and to retard adhesion degradation. Remarkably extending service life of tire.
