Dirt, antifog purpose.
What the present invention studied is the glass applied to bus platform, these glass generally have the characteristics that large area, make
Dosage is especially big, long-term unprotect is displayed in outdoor, it is internal it is general have an advertisement (it is required that good transmittance), cleaning frequency it is low (it is required that
Self-cleaning function), in summary require, the present invention provides it is a kind of it is inexpensive be used for bus platform carry self-cleaning function
Glass preparation method.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of carries automatically cleaning work(for bus platform
The preparation method of the glass of energy.
Technical scheme is as follows：
A kind of preparation method of glass with self-cleaning function for bus platform, comprises the following steps：A, will divide
Son amount is dissolved in organic solvent for the polystyrene of 6000-10000 and is made into polystyrene solution；
B, above-mentioned solution spraying is taken to form uniform liquid film on surface to glass, rapidly by the glass of spun solution
It is transferred in 60-80 DEG C of baking oven dry；Repeat 2-3 times, thickness of dry film is reached 10-15mil；
C, solution is sprayed on glass again, the substrate of glass of spun solution is transferred in liquid nitrogen rapidly carry out it is low
Temperature freezing, then it is put into togerther in freeze drier with liquid nitrogen and is freeze-dried 30-50min, it is to be frozen to finish what is taken out afterwards
Sample, you can.
Preferably, in the step A, the organic solvent is ether, toluene, in dimethylbenzene any one or
A variety of combinations.Preferably ether.
Preferably, in the step A, the concentration of polystyrene solution is 8-15mg/mL.

The invention has the beneficial effects that：The present invention is using the polystyrene of 6000-10000 as thin-film material to glass
Surface is handled, and first basilar memebrane is formed in glass surface in the form of spraying heated drying in processing procedure, first, can increase
The adhesion strength of glass surface and film, second, can be with the wear-resisting property of enhanced film；Subsequently again with the side of spraying freeze-drying
Formula forms the porous self-cleaning film with micro-nano structure；The glass with self-cleaning function of the present invention not only need not be artificial
Wiping can just keep bright and clean clean in a long time, and preparation method is simple, of low cost, be adapted to large-area applications in public transport
Platform glass.
