    • The invention relates to a multilayered metal oxide film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer formed on the glass substrate and a second metal oxide layer formed on the first layer. To make the first layer minutely rough, at least two sols are respectively prepared from at least one compound selected from the group consisting of metal alkoxides and metal acetylacetonatos, such that polymers of the sols have different average molecular weights. Then, the at least two sols are mixed with a solvent so as to prepare a first coating solution. The first coating solution is applied to the glass substrate so as to form thereon a first sol film. The thus coated glass substrate is heated so as to transform the first sol film into the first metal oxide layer. To form a water-repellent metal oxide film on the first layer, a silane compound containing a fluorocarbon group is mixed with a solvent so as to prepare a second coating solution. After that, the second coating solution is applied to the first metal oxide layer so as to form thereon a second sol film. Then, the glass substrate is heated so as to transform the second sol film into the second metal oxide layer which is water-repellent.
    • 本发明涉及通过溶胶 - 凝胶法在玻璃基板上形成的多层金属氧化物膜。 该膜具有形成在玻璃基板上的第一金属氧化物层和形成在第一层上的第二金属氧化物层。 为了使第一层微小,至少两种溶胶分别由至少一种选自金属醇盐和金属乙酰丙酮酸的化合物制备,使得溶胶的聚合物具有不同的平均分子量。 然后,将至少两种溶胶与溶剂混合,以制备第一涂布溶液。 将第一涂布溶液施加到玻璃基板上,以在其上形成第一溶胶膜。 将如此涂覆的玻璃基板加热,以将第一溶胶膜转化为第一金属氧化物层。 为了在第一层上形成拒水性金属氧化物膜,将含有碳氟化合物基团的硅烷化合物与溶剂混合以制备第二涂布溶液。 之后,将第二涂布溶液施加到第一金属氧化物层上,以在其上形成第二溶胶膜。 然后,对玻璃基板进行加热,将第二溶胶膜转化为防水性的第二金属氧化物层。

    • The disclosure relates to a metal oxide film formed on a glass substrate by the so-gel process with using a solution of a metal alkoxide. To afford water repellency to the oxide film, a fluoroalkylsilane is mixed with an alkoxysilane solution in the molar ratio of the alkoxysilane to the fluoroalkylsilane ranging from 1:10 to 10:1. Then, the mixed solution is diluted with a solvent such that the total concentration of the alkoxysilane and the fluoroalkylsilane is from 1 to 10 wt % in a diluted solution. Then, water in the amount of 100 mol % to 1000 mol % of the total amounts of the fluoroalkylsilane and the alkoxysilane is added to the diluted solution so as to partially hydrolyze the fluoroalkylsilane and the alkoxysilane, thereby forming a sol. Then, the sol is applied to the glass substrate, and the coated glass substrate is heated so as to form the metal oxide film thereon.
    • 本公开涉及通过使用金属醇盐溶液的凝胶法在玻璃基板上形成的金属氧化物膜。 为了提供对氧化膜的拒水性,将氟烷基硅烷与烷氧基硅烷溶液以1:10至10:1的摩尔比与烷氧基硅烷与氟代烷基硅烷的摩尔比混合。 然后,用溶剂稀释混合溶液,使稀释溶液中烷氧基硅烷和氟烷基硅烷的总浓度为1〜10重量%。 然后,向稀释溶液中加入氟烷基硅烷和烷氧基硅烷总量的100摩尔%至1000摩尔%的水,以使氟烷基硅烷和烷氧基硅烷部分水解,从而形成溶胶。 然后,将该溶胶涂布在玻璃基板上,对该被覆玻璃基板进行加热,在其上形成金属氧化膜。
