    • The invention relates to a water-repellent glass pane having a glass substrate and a water-repellent film formed thereon. This glass pane is prepared by a first or second method. The first method includes sequential steps of (a) mixing together a raw material for producing the water-repellent film, an organic solvent for diluting the raw material, and water for hydrolyzing the raw material, such that the raw material is subjected to hydrolysis and then to dehydration and polycondensation, thereby to turn a mixture of the raw material, the organic solvent and the water into a sol; (b) adjusting water content of the sol, thereby to prepare a coating liquid; and (c) applying the coating liquid to the glass substrate, in an atmosphere having a first temperature and a relative humidity. The second method includes sequential steps of: (a) subjecting a surface of the glass substrate to an abrasive treatment; (b) subjecting the surface of the glass substrate to an acid treatment; and (c) applying a coating liquid to the surface of the glass substrate. The glass pane prepared by the first or second method is superior in abrasion resistance, sunshine resistance, a hardness, adhesion to the glass substrate, and water-repellency for a long time.
    • 本发明涉及一种具有玻璃基板和形成在其上的防水膜的防水玻璃板。 该玻璃板通过第一种或第二种方法制备。 第一种方法包括以下顺序步骤:(a)将用于制备防水膜的原料,用于稀释原料的有机溶剂和用于水解原料的水混合在一起,使原料进行水解, 然后脱水缩聚,将原料,有机溶剂和水的混合物变成溶胶; (b)调节溶胶的含水量,由此制备涂布液; 和(c)在具有第一温度和相对湿度的气氛中将涂布液涂布到玻璃基板上。 第二种方法包括以下顺序的步骤:(a)对玻璃基板的表面进行磨料处理; (b)对玻璃基板的表面进行酸处理; 和(c)将涂布液施加到玻璃基板的表面。 通过第一种或第二种方法制备的玻璃板在耐磨性,耐日光性,硬度,与玻璃基材的粘附性以及长时间的拒水性方面都是优异的。
