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.

가설 설정
3. Film thickness from Alpha-Step was very thin and increased with treatment time, but adhesion decreased with film thickness.
제안 방법
In this study, zinc plated steel tire cords were subjected to RF plasma polymerization coating of acetylene or butadiene in combi nation with Argon plasma etching and argon carrier gas. These processes resulted in excellent adhesion between steel tire cord and rubber compounds.
성능/효과
2. Water contact angle analysis of plasma polymer coated tire cords revealed that plas ma polymerization increased water contact angle and thus hydrophobicity of tire cords without altering the surface roughness sig nificantly.
4. FT-IR analysis indicated that the pres ence of C=C double bonds may be respon sible for the enhanced pull-out forces with acetylene plasm거 polymerization coating, compared to butadiene plasma polymerizatio.
