中文摘要 | 汽車雨刷膠條的橡膠材質直接影響雨刷之耐候及磨潤特性,而三元乙丙橡膠(Ethylene propylene diene monomer rubber, EPDM rubber)具有良好的化學穩定性及耐候性,但其與玻璃間的摩擦係數相對較高,且由於其化學穩定性而不適用雨刷膠條常見的表面鹵化法及石墨被覆法,故無法解決高摩擦係數的問題。本研究嘗試使用電漿活化EPDM膠條刃部表面,再被覆減摩劑,並改變不同電漿參數以探討電漿活化對EPDM膠條在玻璃上之磨潤特性的改善程度,特別是觀察膠條在800,000次的往復掃刷過程中,摩擦係數之變化情形。結果顯示電漿處理可大幅加強EPDM雨刷膠條表面被覆減摩劑之附著性,並使摩擦係數明顯降低,其降低幅度可達50 %。最佳製程參數是中電漿功率及低電漿掃瞄速度。 |
英文摘要 | The rubber properties of automobile wiper blades have a direct impact on their resistance to weathering and tribological performance. Ethylene propylene diene monomer (EPDM) rubber has good chemical stability and weatherability. However, its friction coefficient on glass is relatively high, and the frequently-used friction reducing methods of wiper blades, e.g. graphite-coating and halogenation treatments, are not applicable due to the low surface energy and good chemical stability of EPDM. This study tried to use plasma to activate the surface of EPDM wiper blades, followed by the deposition of friction reducer. Plasma parameters were tuned followed by coating friction reducer to improve the tribological behaviors of EPDM wiper blades on glass. In particular, the variations of friction coefficients of these wiper blades with wiping cycles were investigated during 800,000 reciprocating sweeps. The results show that plasma treatments can significantly enhance the adhesion of friction reducer to EPDM wiper blades, and the reduction in the friction coefficient is as high as 50%. As to plasma process parameters, a low scanning speed helps to fully activate the wiper blades and thus to reduce the friction coefficient. The optimal process parameters are medium plasma power and low plasma scanning speed. |
