By silicon fluoride come modified gel, performance is stablized, and modified silica dioxide gel has super-hydrophobicity, and water contact angle can
To reach 150 ° or more.
The preparation method of self-cleaning glass according to an embodiment of the present invention is described below with reference to Fig. 1.
The preparation method of self-cleaning glass according to an embodiment of the present invention, includes the following steps:
Step 1, sheet glass is provided.
Preferably, sheet glass can be cleaned.It specifically can be such that and take sheet glass, by the glass hydroxide
Sodium solution cleaning, is hereafter cleaned with bath of glass, is then cleaned with deionized water, most red with being dried with nitrogen.
More specifically, the common glass sheet of interception certain size, such as the sheet glass of 5cm × 5cm size, it is put into hydroxide
Immersion or 20~40min of ultrasonic cleaning in sodium solution (0.2~0.8wt%) are then cleaned several times with bath of glass, remove glass
The impurity dirt on surface, is finally rinsed with deionized water.During flushing, when deionized water in glass surface neither at stock
Flow down, be not also polymerized to water droplet, as soon as but surface formed layer uniform moisture film, illustrate that glass has cleaned up.Finally,
Sheet glass dried up with nitrogen spare.
Step 2, automatic cleaning coating is set in the glass sheet surface.
Herein, it should be noted that, can be according to painting in the specific method of glass sheet surface setting automatic cleaning coating
It covers the dosage form difference of material and uses different methods.
When coating material is one-pack type, the coating material can be directly coated in the glass sheet surface.
For example, the sheet glass is placed on photoresist spinner in plant produced self-cleaning glass, improved silica is added dropwise
Collosol and gel, with 1200~2000 revs/min of revolving speed 60~100s of whirl coating, then in 80~120 DEG C of 3~5min of heating, this
1~3min of natural cooling afterwards；It repeats drop glue-heating stepses total 3-5 times, is finally putting into 80~120 DEG C of progress in thermostatic drying chamber
30~45min of thermosetting obtains the self-cleaning glass.
In addition, later period after for example individual consumer buys in coating material, oneself (example when glass surface forms self-cleaning layer
Such as, the back-mirror glass etc. of the window-glass, automobile of house), directly the coating material can be added dropwise in glass surface, passed through
Scraper plate etc. is scratched, and finally erases extra coating material with one piece of clean cloth, can also be formed after spontaneous curing certainly
Clean layer.
When coating material is 2 dosage form, in plant produced self-cleaning glass, it is preferable that the step 2 includes:
Step 21, the sheet glass is placed on photoresist spinner, the Silicon dioxide sol-gel is added dropwise, with 1200~2000
Rev/min 60~100s of revolving speed whirl coating；
Step 22, in the glass sheet surface for being formed with the Silicon dioxide sol-gel, using spray-on process spray described in change
Property solution；
Step 23, by the sheet glass in 80~120 DEG C of 3~5min of heating, hereafter 1~3min of natural cooling；
Step 24, repeating said steps 21 are total 3-5 times to step 23, be finally putting into thermostatic drying chamber 80~120 DEG C into
Row 30~45min of thermosetting, obtains the self-cleaning glass.
Certainly, it for the coating material of 2 dosage forms, after individual consumer buys in, simply following can be formed step by step certainly
Clean layer:
Firstly, being added dropwise Silicon dioxide sol-gel in glass surface, scratched by scraper plate etc., hereafter, in the glass
Glass surface sprays modified solution by watering can, and it is molten to repeat drop glue-spray modification again after spontaneous curing (such as 10-30 minutes)
Liquid 3-5 times repeatedly, can form self-cleaning layer.
In the following, the preparation method of self-cleaning glass according to the present invention is described in further detail by specific embodiment.
Embodiment 1
Firstly the need of preparing Silicon dioxide sol-gel: configuring 5ml tetraethyl orthosilicate and 40ml ethyl alcohol in beaker
Mixed solution carries out magnetic agitation at room temperature；Then gradually appropriate ammonium hydroxide, every minor tick magnetic is added dropwise in the mixed solution into stirring
Power stirs 30min, observes mixed solution reactiveness；Finally, mixed solution is allowed to continue magnetic agitation after ammonium hydroxide completion of dropwise addition
300min reacts it sufficiently, can be prepared by Silicon dioxide sol-gel after standing aging 12h.
Followed by the preparation of modified solution: 97wt% perfluorododecyl trichlorosilane is diluted to dehydrated alcohol
After 0.3wt%, it is put into supersonic wave cleaning machine and shakes 20 minutes, until it is uniform, as modified solution, it is fitted into standby in automiser spray
With.
It is the cleaning of substrate of glass again: cuts the sheet glass of 2.5cm × 2.5cm size, be put into sodium hydroxide solution
Ultrasonic cleaning 30min in (0.5wt%) is then cleaned three times with bath of glass, removes the spot of glass surface, finally spend from
Sub- water is rinsed to also being formed without water droplet without leaving at stock water.Finally, sheet glass dried up with nitrogen spare.
Spin coating whirl coating, modified and thermosetting: sheet glass being placed on whirl coating platform, collosol and gel is dropped evenly, with 1500 turns/
The revolving speed whirl coating 60s of minute, then modified solution is sprayed onto glue surface with spray-on process, even spraying once completes the modification of gel,
Then it is put on 100 DEG C of hot plate and heats 3min, remove cooling 1min, repeatedly above-mentioned whirl coating, modification and heating process 5 times, most
After be put into 100 DEG C of thermosetting 30min in thermostatic drying chamber.It can be obtained the transparent glass of super hydrophobic surface.
Glass using above-mentioned preparation is only sample, can be amplified according to a certain percentage, raw as large-scale industry
It produces and uses, it can be widely applied to the field of various self-cleaning glass applications.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
