Problems solved by technology

There have been reports of similar water-repellent agents before, and most of their formulas use hydrophobic substances such as silicone oil (such as methyl silicone oil), or use general hydrophobic surfactants, but their disadvantage is that the retention time of the hydrophobic film is too short , poor water-repellent effect, etc.

Abstract

The invention provides a hydrophober comprising tridecafluoro octyl trimethoxy silane, ethyl orthosilicate, dodecyltrimethylammonium chloride, isopropanol and ethylic acid. The method for preparing hydrophobic glass comprises the following steps: (1) preparing the hydrophober, taking all the components in a certain proportion, mixing and stiring uniformly; (2) cleaning and drying glass to be processed; (3) spraying the hydrophober prepared in the step (1) on the surface of the glass processed in the step (2); and (4) drying the glass on which the hydrophober is sprayed in the step (3) so thata hydrophobic film layer is dried and solidified to obtain a finished product. The hydrophober has easily obtained components, simple preparation process and good film forming performance and enablesthe service life of a hydrophobic film to be greatly prolonged; in addition, the acid and alkali resistance and the weather resistance of the prepared hydrophobic glass are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of functional glass, and relates to a water-repellent agent and a method for preparing water-repellent glass by using the water-repellent agent. Background technique [0002] Due to the high surface energy of the glass surface, the resulting surface tension is much higher than that of water, so water has wettability to glass. At present, most of the art glass in the construction and home decoration market is directly or reprocessed from float glass, and none of them have water-repellent effect. Therefore, when the surface of the glass is stained with water, a layer of water film will be formed, causing the water droplets to not easily slip off. frequency. Therefore, how to improve the stain resistance of the glass surface, reduce the difficulty and cost of cleaning and maintenance; improve the acid and alkali resistance and weather resistance of the glass, and finally improve and improve the functional val...
