Abstract
The utility model discloses a piece of high-transmittance dimming glass. The high-transmittance dimming glass comprises a first layer of glass substrate, a second layer of glass substrate and a third layer of glass substrate, wherein a spacing strip is arranged between the first layer of glass substrate and the second layer of glass substrate to form a hollow glass structure; a gelatinous layer, a polymer dispersed liquid crystal (PDLC) material layer, is arranged between the second layer of glass substrate and the third layer of glass substrate; two conductive films are respectively arranged on the upper side and the lower side of the gelatinous layer, respectively connected with chaffs, and led out of the glass; and at least one of the three layers of glass substrate is ultrawhite float glass. The high-transmittance dimming glass has the light transmittance reaching more than 70 percent under the action of external voltage, conforms to the requirement for high-transmittance glass, and improves the bottleneck restricting large-scale popularization of the dimming glass with low visible light transmittance.
Description
Technical field
The utility model belongs to glass deep processing field, relates in particular to a kind of high dimming glass.
Background technology
PDLC (Polymer dispersed liquid crystal is abbreviated as PDLC) is a kind of electro-optic response material, can solidify to form co-mixing system with polymer monomer.This system changes the direction of optic axis of liquid crystal molecule under the extra electric field effect, when its refractive index and polymer phase coupling, be clear state.After removing electric field, liquid crystal molecule recovers initial astigmatic attitude, thereby opaque.Through PDLC being coated between two electro-conductive glass, process dimming glass.Electro-conductive glass is meant in surfaces coated and is coated with the glass that indium tin oxide target, Zinc-aluminium or indium-zinc oxide rete can conduct electricity.
At present, dimming glass begins progressively to be applied on the buildings.Because its transmittance receives the dual restriction of float glass and PDLC, visible light transmissivity generally is lower than 70% problem when having "on" position, has greatly limited applying of dimming glass.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of the utility model provides a kind of high dimming glass, can realize the significantly raising of dimming glass transmittance.
In order to reach above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind of high dimming glass; Comprise ground floor glass substrate, second layer glass substrate and triplex glass substrate, form the double glazing structure, between second layer glass substrate and the triplex glass substrate gelatinous layer is set thereby spacer bar is set between ground floor glass substrate and the second layer glass substrate; Said gelatinous layer is the polymer dispersion liquid crystal material layer; Said gelatinous layer respectively is provided with one deck conducting film in both sides up and down, and the both sides conducting film is connected with chaff respectively, and is drawn out to glass outer; Wherein, to have a slice at least be ultra-white float glass for said ground floor glass substrate, second layer glass substrate and triplex glass substrate.
As preferably, said ground floor glass substrate, second layer glass substrate and triplex glass substrate are ultra-white float glass.Like this under the impressed voltage effect, this programme product transmittance is up to more than 90%, significantly improved the restriction dimming glass because of the low bottleneck of can't large tracts of land promoting of transmittance.
Above-mentioned conducting film can be selected indium tin oxide target, Zinc-aluminium or indium-zinc oxide for use.Chaff can be selected copper or other metals for use.Above-mentioned spacer bar is aluminum strip or rubber strip, and spacer bar is concordant with glass edge portion, and glass edge portion can be straight flange, arc limit or other irregular limit.
As preferably, charge into air, nitrogen or inert gas in the hollow cavity between ground floor glass substrate and the second layer glass substrate.
As preferably, said ground floor glass substrate, second layer glass substrate and triplex glass substrate are rectangle glass, plane special-shaped glass, curved arc glass or bend glass.Wherein at least two sheet glass substrates are parallel to each other, so that gelatinous layer to be set.
The utility model is owing to adopted above technical scheme, and under the impressed voltage effect, transmittance can reach more than 70%, meet the requirement of high light transmittance ratio glass, has improved the restriction dimming glass because of the low bottleneck of can't large tracts of land promoting of visible light transmissivity.
