Adhesion of Tire Bead Wire with Rubber



2003

We do Acid dip copper plating on 0.965 mm wire which contains small amount of tin . The coating of wire typically contains 0.45 g/kg of copper coating in which % tin is 2 .This wire is used in Tire Industry which goes in bead of tyre which take maximum load of tyre as it fits onto wheel rim. The adhesion of wire with rubber is an important properties. I like to have information adhesion of this Tire bead wire as follows. What quality of coating is req. to get good rubber adhesion? What is the effect of plating line process parameters on coating quality?

Mr Gudadhe

Do you deposit copper by the passage of Current. Or do you dip the steel and achieve immersion copper deposits without passage of current?

If you do what is called liquoring of steel wire in a copper sulfate solution the deposit will tend to be loosely adherent to the base and usually causes loosely adherent deposits of copper that flake readily or peel off with the rubber.

Copper plating with current on clean surfaces is the right solution.

I am aware the industry has been using the liquoring method as a cheaper substitute for plated copper.

In response to the last part of your question I suggest you appoint a professional Plating consultant to help you set your parameters right.

The copper coating is simply a immersion process and no current is passed. We do peel test also and as such every wire is tested for complete property test including coating. Through research it was found that the sulphur of rubber combines with copper which gives good bond with rubber. I would like to have information on the quality of coating and its effect on rubber adhesion.
