Abstract
The utility model relates to nanometer self-cleaning light-adjusting glass which comprises two layers of glass substrates. A layer of polymer dispersed liquid crystal material and corresponding ITO membranes adhered to both sides of the polymer dispersed liquid crystal material are arranged between the two layers of glass substrates; wherein at least one layer of glass substrate is provided with a layer of nanometer TiO2 membrane at the surface. The utility model adopts the technical proposal that the nanometer TiO2 membrane with an anatase titania crystal structure is arranged on the outer surface of the light-adjusting glass, and making use of the super-hydrophilicity and the photo-catalytic activity of the TiO2 membrane, the nanometer self-cleaning light-adjusting glass not only ensures good light-adjusting effect of the light-adjusting glass, but also realizes the functions of preventing fog, dirt and scale, disinfecting and sterilizing when the light-adjusting glass encounters rain, snow or water vapors.
Description
Technical field
The utility model belongs to glass processing and makes the field, but particularly relates to the nano self-cleaning dimming glass of a kind of disinfection, antifouling de-sludging.
Background technology
Dimming glass is a kind of functional glass that can change self show state fast, presents milky opaque state under the normality, under impressed voltage is regulated, can change pellucidity into.Therefore dimming glass is well suited for being made as building doors and windows, substitutes door curtain/curtain and uses, can conditioning chamber in illumination, can effectively protect privacy again.Dimming glass adopts sheet glass as substrate, condenses easily and hazes but currently used glass substrate runs into the sleety weather rear surface, and attract dirt easily, influences the dimming effect of dimming glass, has limited dimming glass in architectural application.In addition, dimming glass also has as the door glass between bathroom, and common dimming glass condenses easily in contact steam rear surface and hazes, and can't realize good dimming effect.
Nano self-cleaning glass is a kind of new function glass that developed recently gets up.It is provided with the nano-TiO of one deck anatase titanium dioxide crystal structure at glass surface
2Rete has two big characteristics: (1) Superhydrophilic.Because dichloride in anatase type TiO
2Hydrophilic and oleophobic, therefore the surface is difficult for the absorption organic dirt, then only needs clear water just flushable clean to the mineral contaminants that adheres to.(2) photocatalytic activity.Under solar light irradiation, TiO
2Crystal internal cause electron transfer and produce free electron and hole generates active oxygen atom, so airborne bacterium of near surface and viral oxidation can be killed.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model is a kind of nano self-cleaning dimming glass, on the basis of existing dimming glass, sets up one deck nano-TiO
2Film had both guaranteed good dimming effect, had the function of antifouling de-sludging, disinfection again concurrently.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of nano self-cleaning dimming glass, comprise the layer glass substrate, be provided with the one layer of polymeric dispersed liquid crystal material between the layer glass substrate and be close to the ITO film of polymer dispersion liquid crystal material both sides accordingly, wherein, one deck glass substrate surface is provided with one deck nano-TiO at least
2Film.
Above-mentioned ITO film can be attached directly to and form ito glass on the glass substrate; Also can be attached on the PET film, the PET film is connected with glass substrate by the PVB film again.
Above-mentioned nano-TiO
2Film is the anatase titanium dioxide crystal structure.
The technical solution of the utility model is provided with the nano-TiO of one deck anatase titanium dioxide crystal structure at the dimming glass outside surface
2Film utilizes TiO
2The Superhydrophilic of film and photocatalytic activity had both guaranteed the dimming effect that dimming glass is good, realized that again dimming glass is met sleet, steam does not haze antifouling de-sludging, but and the function of disinfection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1: a kind of nano self-cleaning dimming glass as shown in Figure 1, comprise layer glass substrate 1, be provided with one layer of polymeric dispersed liquid crystal material 3 between the layer glass substrate 1 and be close to the ITO film of polymer dispersion liquid crystal material 3 both sides accordingly, on one deck glass substrate surface, be provided with one deck nano-TiO
2Film 4; Above-mentioned ITO film is attached on the PET film 5, and PET film 5 is bonding by PVB film 2 and glass substrate 1.
The manufacturing process of present embodiment is as follows:
The monomer that above-mentioned polymer dispersion liquid crystal material adopts is methacrylic acid fourth fat (C
8H
14O
2), liquid crystal is cholesteryl nonanoate (C
36H
62O
2), be that 1: 1 proportioning is mixed by mass ratio, and heated and stirred is even, about 20 minutes of time, cool to room temperature then.
Chilled monomer, liquid crystal compound are added drain hopper, open baiting valve then, blowing between the ito surface of two-layer ITO plastic film (base material is PET) is noted the control dispensing speed.With a pair of steel rider of two-layer ITO plastic film, note the gap between control two steel riders simultaneously, common big 10～20 μ of thickness (micron) than two-layer plastic film by uniform rotation.Traction is advanced, and the district is cured by the UV light irradiation, can fully solidify for the assurance Polymer Dispersed Liquid Crystal simultaneously, and suitable haulage speed is 2～5 meters/minute.The product that obtains after the curing is called light modulation film.
As shown in drawings, light modulation film is located between the layer glass substrate, between light modulation film and every layer of glass substrate, also is provided with one deck PVB film, form laminated glass.Laminated glass is sent into the roll-in stove, send into still kettle after the pressing closely.The still kettle programming rate is 3 ℃/minute, and the rate of rise is the 900Pa/ branch, and upper temperature limit is 130 ℃, and upper pressure limit is 1 * 10
5Pa kept 30 minutes after reaching the higher limit of temperature and pressure, stopped the pressurization of heating then, obtained dimming glass after cooling off with stove.
The surface of glass substrate is cleaned and vacuum drying, adopted plasma spray coating process coating dichloride in anatase type TiO on the surface
2At first to nano-TiO
2Powder carries out granulation to be handled, and improves its adhesive property.With nano-TiO
2Powder and adhesive (adhesive gross mass be granulation amount about 4%) fully mix the back and add in the stirring machine, through stirring treat that solvent acetone is fully volatilized after, can shut down discharging; sieve then; powder behind the sieve is inserted in the batch mixing dish, fully dry, be no less than 12 hours drying time.Size distribution after the granulation is in 80～105 mu m ranges.Then to glass basis surface to be painted clean, blasting treatment, spray with plasma spraying equipment again, can obtain stabilized nano TiO
2Coating.
