Abstract

The surface of wiper blade(W/B) rubber was chlorinated by chemical treatment method using the hydrochloric acid(HCI) and sodium hypochlorite(NaOCl). From the results of contact angle measurement, friction coefficient measurement, and ATR-IR spectra, the surface characteristics of chlorinated W/B rubber with time of chlorination were studied. Contact angles for W/B rubber with increasing time of chlorination and chlorine concentration were measured for the water and ethylene glycol. From the results, contact angle fell rapidly with increasing time of chlorination and chlorine concentration, reaching a constant value after about 10min. And the wettability of W/B rubber surface by means of chlorination has been improved. For an unchlorinated W/B rubber, the friction coefficient with time of chlorination decreased from 1.27 to 0.20~0.23 on full chlorination. As the results it was considered that abrasion resistance of W/B rubber surface has been also improved. The values of pH and $Cl^-$ ion concentration in a chlorine treatment solution decreased as the extent of chlorination of W/B rubber surface increased. From the results of ATR-IR spectra, it was observed that C=C double band of W/B rubber surface transformed into C-Cl band, but quantitative determination of the extent of chlorination was not feasible because of the complexity of chlorination reactions.
