Process for improving the adhesion of vulcanised rubber to copper alloys and to aluminum or aluminum alloys

摘要

A method for increasing the adhesion of vulcanized sulfur-containing, conductive rubber mixtures (especially those containing carbon black) to copper alloys (especially brass or brass coated parts) and to aluminum or its alloys or parts with aluminum-containing coatings comprises applying an electrical potential to the mixture during vulcanization. Independent claims are included for: (a) a process for the production of articles consisting of rubber mixture(s) as above in contact with the brass- or aluminum-containing surface of a metal part, by applying a voltage to the part or the contact surface during vulcanization; and (b) articles, especially industrial rubber articles, made by this process.
