Abstract
The present invention relates to a manufacture method for hydrophobic solutions and hydrophobic glass. A hydrophobic solution is formed by the method that trifluorooctyl triethylsilane, ethyl orthosilicate and absolute alcohol are mixed, and the compositions respectively comprise the weight proportion: 0.8 to 5% of trifluorooctyl triethylsilane CF3 (CF2)-5C-2H-4Si (OC-2H-5)-3, 0.2 to 2% of ethyl orthosilicate Si (OC-2H-5)-4 and 93 to 99% of absolute alcohol C-2H-5OH. Deionized water with 1 to 4% of the total weight and 0.1 to 0.5% of hydrochloric acid with the concentration of 37% are filled in the solution, and the compositions are stirred for 5 to 20 hours after mixed. The method for manufacturing hydrophobic glass is divided into four stages of the cleanness of glass, the preparation of the hydrophobic solution, the coating of hydrophobic coatings and the solidification. Glass is placed under the environment of 25 to 350 DEG C for 10 minutes to 72 hours, and a firm hydrophobic coating is formed by the reaction of the hydrophobic solution and the surface of the glass. The method is especially suitable for manufacturing front windscreens for cars.
Description
Technical field
The present invention relates to the surface treatment of glass, especially a kind of hydrophobic liquid and utilize this hydrophobic liquid to make the method for hydrophobic glass.
Background technology
Existing vehicle glass is made by float glass or general sheet glass.Water has wetting property to float glass or general sheet glass, because the surface tension of glass is bigger 4 times than water, promptly glass surface has higher surface energy.Existing employed glass of every profession and trade or the goods that become with this kind glass processing as vehicle glass, all do not have the hydrophobic function.Therefore, at sleety weather, glass surface forms water membrane, causes the visual field smudgy, and particularly therefore the motorist often causes getting into an accident.
Summary of the invention
The object of the present invention is to provide a kind of hydrophobic liquid, and utilize its method of making a kind of hydrophobic glass, cause glass surface to form the little film of layer of surface warp tension ratio water, water is shown not infiltrating function.
Technical scheme of the present invention is achieved in that a kind of hydrophobic liquid, and it is to be mixed by following material, and its moiety and weight ratio are respectively:
(1) ten trifluoro octyl triethoxyl silane CF
3(CF
2)
5C
2H
4Si (OC
2H
5)
30.8～5%
(2) tetraethoxy Si (OC
2H
5)
440.2～2%
(3) dehydrated alcohol C
2H
5OH 93%～99%
And then to add the deionized water of gross weight 1～4% and 0.1～0.5% concentration in this solution be 37% hydrochloric acid, mixes the back and stir and forming in 5～20 hours.
The method of utilizing above-mentioned hydrophobic liquid to make hydrophobic glass is divided into four-stage, is respectively:
(1) glass carries out clean:
Water scrub after drying cleans with clean-out system again, after the cleaning, washes residual to there not being clean-out system, dry again;
(2) preparation hydrophobic liquid;
(3) coating hydrophobic film:
Above-mentioned hydrophobic liquid evenly is coated on the outside surface (spraying, dip-coating, all can smear) of glass; Then the surface is dried with towel or paper handkerchief, the consumption of hydrophobic liquid is 30～80ml/m
2, this consumption is the actual amount of coating;
(4) solidify:
Glass is placed under 25～350 ℃ the environment, 10 minutes to 72 hours, hydrophobic liquid and glass surface reaction formed one deck hydrophobic film.
Also the glass that is coated with hydrophobic film can be placed under 200-350 ℃ the environment, through 10-20 minute after fixing.
The present invention has that hydrophobic liquid preparation is simple, and coating is easy to characteristics, and uses the made glass with hydrophobic function of method provided by the invention and have more following characteristics:
(1) water is to contact angle 〉=90 of glass °;
(2) surface has non-adhesive.The not only not sticking water of this glass, the pollutent in the obstruction visuals field such as simoniz, earth, smoke evacuation, the worm bones of the body, birds droppings, fingerprint, ink also is easy to remove, and it is also easy that freezed in winter, frost are removed;
(3) because there is one deck hydrophobic film on the hydrophobic glass surface, can effectively stop separating out of basic ion in the glass, so can prevent the weathering of glass and mouldy;
(4) the hardness ratio glass body of hydrophobic film is big, can prevent that therefore glass from scratching;
(5) chemical resistance, weathering resistance, rub resistance are all relatively good.
Because the above-mentioned characteristic of hydrophobic glass, it not only can be used for vehicle glass, also can use on transportation equipments such as train, aircraft, boats and ships.If hydrophobic glass is used on transportation equipments such as automobile, the rainwater water droplet effectively disperses under the blast effect, even the rainy day front windshield does not use windshield wiper can keep the good visual field yet, thereby has improved the driving safety of facilities for transport and communication such as automobile.
In addition, the building that requirements such as Highrise buildings, restaurant, hotel are throughout the year attractive in appearance is if use this glass can reduce maintenance cost, and therefore, hydrophobic glass has wide application prospect.
The invention will be further described below in conjunction with specific examples.
