Abstract

Zinc plated steel tire cords were subjected to RF plasma etching of argon, followed by plasma polymerization coating of acetylene or butadiene in order to enhance adhesion to rubber compounds. Plasma polymerization was carried out under optimized conditions of 10 W, 30 sec, 30 mTorr for acetylene and butadiene gas, while plasma etching was performed at 90W, 10min and 30mTorr. The adhesion of tire cords was evaluated via Tire Cords Adhesion Test (TCAT) and the failure surfaces of the tested samples were analyzed by SEM. Polymer coating by plasma polymerization was also characterized by FT-IR, Alpha-Step and dynamic contact angle analyzer in order to elucidate the adhesion mechanism.
