AROMATIC TRIAZOLE PRECIPITATION COMPOUND AND OXIDIZING COMPOUND FOR INCREASED SURFACE PROTECTION AND IMPROVED ADHESION OF BRASS-COATED STEEL TO RUBBER

The vulcanized aged adhesion of rubber to clean brass coated steel cord is improved by the use of benzotriazole (BTA) and/or a precipitation compound such as cyclohexylamine borate and\\or an oxidation compound such as zinc chromate. These agents are added directly to the surface of the cord or to t...

Zusammenfassung:	The vulcanized aged adhesion of rubber to clean brass coated steel cord is improved by the use of benzotriazole (BTA) and/or a precipitation compound such as cyclohexylamine borate and\\or an oxidation compound such as zinc chromate. These agents are added directly to the surface of the cord or to the rubber immediately adjacent to the cord. BTA treatment reduces surface degradation of the cord and the precipitation compound and oxidation compound aid in improving aged adhesion. Preferably the cord is cleaned in an acid dip, which can be used to deposit desired anions on the cord surface, prior to treatment.
