Because all data above are the description of scope, the data combination used in actual preparation process
Type is varied, below in conjunction with two groups of specific data, introduces the specific preparation method of the Hydrophobic glass.
Mode one
In step one, 1 part of cerium rouge is mixed evenly with 20 parts of distilled water, dispersion liquid is obtained, with wiping
Wiping cloth (rags) dips dispersion liquid and wipes glass surface to be coated, using distilled water that glass sparge to be coated is clean；It will rinse well again
Film glass to be plated be placed in the mixed solution that the concentrated sulfuric acid and the hydrogen peroxide that mass ratio is 3 to 1 are constituted and soak 30 minutes, again
It is using distilled water that glass sparge to be coated is clean.
In step 2,1 part of ammoniacal liquor, 15 parts of ethanol, 1.25 parts of tetraethyl orthosilicates are mixed 30 minutes at room temperature,
Silicon dioxide gel is obtained, is then added to 2.5 parts of molecular weight in above-mentioned silicon dioxide gel for 200 polyethylene glycol, after
It is continuous that reaction 2 hours is stirred at room temperature, mixed liquor is obtained, then 5 parts of octadecyl trimethoxysilanes are added to above-mentioned mixing
In liquid, stirring reaction 24 hours at a temperature of 40 degrees Celsius obtain silica/polyethylene glycol mixed sols.
In step 3, the film glass to be plated after cleaning is immersed in above-mentioned silica/polyethylene glycol mixed sols, adopted
With the mode plated film 1 time of czochralski method, then coated glass is placed in 80 degrees Celsius of vacuum drying chamber solidified 60 minutes, during which protect
It is 0.06 standard atmospheric pressure to hold the atmospheric pressure in vacuum drying chamber.
Coated glass after the cooling that above-mentioned steps are obtained, by actual measurement, its surface contact angle is 112.6 °.
Likewise, combining another group of specific numerical value below, the preparation method of Hydrophobic glass is described.
Mode two
In step one, 3 parts of cerium rouges are mixed evenly with 50 parts of distilled water, dispersion liquid is obtained, with wiping
Wiping cloth (rags) dips scattered volume and wipes glass surface to be coated, using distilled water that glass sparge to be coated is clean；It will rinse well
Film glass to be plated be placed in the mixed solution that the concentrated sulfuric acid and the hydrogen peroxide that mass ratio is 3 to 1 are constituted and soak 50 minutes, again
It will be rinsed well using distilled water with coated glass.
In step 2,2 parts of ammoniacal liquor, 22 parts of acetone, 2.25 parts of butyl silicates are mixed 60 minutes at room temperature,
Silicon dioxide gel is obtained, is then added to 3.5 parts of molecular weight in above-mentioned silicon dioxide gel for 400 polyethylene glycol, after
It is continuous that reaction 3 hours is stirred at room temperature, mixed liquor is obtained, 8 parts of octadecyl trimethoxysilanes are being added to above-mentioned mixing
In liquid, stirring reaction 40 hours at a temperature of 45 degrees Celsius obtain silica/polyethylene glycol mixed sols.
In step 3, the film glass to be plated after cleaning is immersed in above-mentioned silica/polyethylene glycol mixed sols, adopted
With the mode plated film 3 times of czochralski method, then coated glass is placed in 100 degrees Celsius of vacuum drying chamber solidifies 80 minutes, during which
It is 0.08 standard atmospheric pressure to keep the atmospheric pressure in vacuum drying chamber.
Coated glass after the cooling that above-mentioned steps are obtained, by actual measurement, its surface contact angle is 110.4 °.
Contact angle in above two concrete implementation mode refers to solution-air circle made at gas, liquid, solid three-phase intersection point
Angle theta of the tangent line in face through liquid and solid-liquid boundary line, this definition is to weigh measuring for wetness degree.If 90 ° of θ ＜,
Then the surface of solids is hydrophilic, i.e., liquid is easily wetted solid, it is not easy in surface of solids movement, and the angle is smaller, represents
Wetability is better, and the schematic diagram of contact angle in this case is as shown in Figure 2；If 90 ° of θ ＞, the surface of solids be it is hydrophobic, i.e.,
Liquid is not easily wetted by solid, is easily moved in the surface of solids, the angle is bigger, represents that wetability is poorer, connecing in this case
The schematic diagram of feeler is as shown in Figure 3.
Because the contact angle of the coated glass finally obtained in above two implementation is respectively 112.6 ° and 110.4 °,
90 ° are much larger than, it can thus be seen that the coated glass obtained by method in the embodiment has obvious hydrophobicity, from
And water droplet can be made rapidly to be slid from coated glass, adhesion of the water droplet on coated glass is reduced, this is added
The light transmittance of coated glass.
In the present embodiment, all numbers are ratio of each liquid capacity relative to unit volume, above in order to clear
The proportionate relationship for showing volume between each class I liquid I of Chu, the expression way of special envoy's number, it is necessary to will in actually preparing
It is converted into milliliter mL or rises the standard units such as L.
The preparation method of Hydrophobic glass in the embodiment of the present invention, methods described includes：Clean to be coated using dispersion liquid
Glass, the film glass to be plated after being cleaned, prepares silicon dioxide gel, and volume is added in the silicon dioxide gel pre-
If the first number range is interior and molecular weight is in the range of default second value polyethylene glycol and volume are in default third value model
Interior low-surface energy substance is enclosed, silica/polyethylene glycol mixed sols is generated, the film glass to be plated after the cleaning is immersed
In the silica/polyethylene glycol mixed sols, plated film is carried out to the film glass to be plated using czochralski method, plated film glass is obtained
Glass.The light transmittance of coated glass is improved by the above method.
