Enhanced Adhesion of Tire Cords via Argon Etching and Acetylene Plasma Polymerization

아르곤 에칭과 아세틸렌 플라즈마 중합에 의한 타이어 코드의 접착성 향상연구

Steel tire cords were coated via RF Plasma Polymerization of acetylene in order to enhance adhesion to rubber compounds. Adhesion of tire cords was measured by TACT as a function of plasma polymerization and argon etching conditions such as power, treatment time and chamber pressure. Tested tire cords were analysed by SEM to elucidate the adhesion mechanism. The highest adhesion values were obtained with argon etching condition at 90W, 10min, 30mtorr followed by acetylene plasma polymerization condition at 10W, 30sec., 30mtorr. In SEM analysis, the plasma polymerized tire cord at the optimized condition showed 100% rubber coverage as observed from brass-plated steel tire cords.
