Embodiment 1

[0027] Preparation scheme of hydrophobic liquid for ordinary tempered glass or ordinary float glass cured at room temperature:

[0028] (a) Tridecafluorooctyltriethylsilane CF 3 (CF 2 ) 5 C 2 h 4 Si(OC 2 h 5 ) 3 5%

[0029] (b) Orthoethyl silicate Si(OC 2 h 5 ) 4 1%

[0030] (c) Absolute ethanol C 2 h 5 OH 94%

[0031] Then add 3% deionized water and 0.4% hydrochloric acid with a concentration of 37% to the solution, mix and stir for 20 hours.

[0032] Hydrophobic glass method:

[0033] (1) Clean the glass:

[0034] Scrub it with water, dry it, and then clean it with a cleaning agent. After cleaning, rinse until there is no cleaning agent residue, and then dry it;

[0035] (2) prepare hydrophobic solution;

[0036] (3) Coating hydrophobic film:

[0037] Apply the above-mentioned hydrophobic liquid evenly on the outer surface of the glass (spray, dip, or smear); then dry the surface with a towel or paper towel, and the amount of th...

Abstract

A process for preparing a hydrophobic solution and a hydrophobic glass used for the windscreen of car is disclosed. Said hydrophobic solution is prepared from CF3(CF2)5C2H4Si(OC2H5)3, Si(OC2H5)4, C2H5OH, deionized water, and hydrochloric acid through proportional mixing, and stirring for 5-20 hr. Said hydrophobic glass is prepared through cleaning glass, preparing said hydrophobic solution, coating it on the surface of glass, and solidifying at 250-350 deg.C for 10 min -72 hr to form a firm hydrophobic film.

Description

Technical field: [0001] The patent of the invention belongs to the field of glass processing, and in particular relates to a hydrophobic liquid and a method for manufacturing hydrophobic glass. Background technique: [0002] Existing automotive glass is made of float glass or general flat glass. Water has wettability to float glass or general flat glass, because the surface tension of glass is 4 times greater than that of water, that is, the surface of glass has higher surface energy. The glass used in various industries or the products processed from this kind of glass, such as automobile glass, does not have the function of water repellency. Therefore, in rainy and snowy weather, a layer of water film is formed on the surface of the glass, resulting in blurred vision, especially for car drivers, which often leads to car accidents. Invention content: [0003] The object of the present invention is to provide a kind of water-repellent liquid, and utilize it to manufactur...
