Said light-regulating glass with relative transmissivity up to more than 90% can be controlled by safty low voltage. The words and pattern can be generated by means of light-regulating part. The 90% or more of ultraviolet ray can be stopped. The sound can be isolated to some extent. The functional material used by said light-regulating glass is a mixture of fine chemicals with definite ratio.

Description

Can local instantaneous dimming glass manufacture method and frame mode thereof

The present invention relates to a kind of can local or whole manufacture method, the frame mode of dimming glass arbitrarily, and the functional material that is adopted.

For many years, the door glass of building and vehicle uses traditional plate glass always, just in recent years, so that adapt to various needs, use coated glass and pad pasting glass, even like this, under the situation of Changes in weather or environment change, also can't change its intrinsic function.Along with the change of ecology, the destruction of ozone layer in the atmosphere, the various width of cloth are penetrated intensity also in increase in the universe; Follow the new century to arrive, the appearance of intelligent dwelling, people express very big expectation to glass function, just can change the light transmittance or the reflectivity of glass according to people's wish, and the present invention arises at the historic moment like this.

Can local instantaneous dimming glass be that a kind of electricity causes dimming glass, it utilizes safe low-voltage to control the state of functional material in polyester film or the glass sandwich, thereby changes its light transmittance.

Two kinds of implementation methods are arranged: a kind of is voltage when being zero, and glass is the frosted state, and a printing opacity is not had an X-rayed, and behind the making alive, glass becomes pellucidity; Another kind is then opposite, and promptly when current potential was zero, glass was clear state, and behind the making alive, glass becomes the frosted state.

When dimming glass was opaque, it was exactly a concealed curtain, therefore had a lot of incomparable advantages.

At first, use dimming glass just the entity curtain needn't be installed again, promptly saved the space, also avoided flying upward, improved indoor sanitary condition because of mobile curtain causes dust.

Dimming glass has antiultraviolet and sound insulation function, and after tested, it can block most ultraviolet lights, and extraneous noise is decayed, so it is a kind of environmentally friendly machine.

But dimming glass is whole implementation not only, also can be to a certain local dimming, as shown in Figure 1.

Also can set the light modulation zone arbitrarily and carry out graduation, accomplish to follow one's bent by user's requirement.Moreover, utilize light modulation also can present literal or formation pattern, as shown in Figure 2.

At a lot of special occasions, dimming glass has many functions, is installed on fixed building and the vehicle that travels, can play prompting or Presentation Function.

And for example, the residential building in China city, general spacing is all less, each other, comes into plain view; The effect that the dimming glass printing opacity is not had an X-rayed will play certain " protection " effect here, for the resident in it provides comfortable, living environment easily.

Dimming glass also has many special application, as spy on, supervision etc.

Multiple function that can local instantaneous dimming glass with giving its extremely wide application prospect, for the exploitation of various functional glass, has been started the beginning.

This dimming glass technical indicator:

Relative light transmittance:＞90%

Ultravioletlight screening:＞90%

Noise attentuation:＞40dB

Driving voltage (D.C.): 0～36V

Response speed: 50ms

Can two kinds of frame modes be arranged local instantaneous dimming glass: first kind of mode is that functional material is coated in the middle of polyester (PET) film, functional membrane is attached on the inner surface of door glass again, and its concrete mode as shown in Figure 3; The second way, in the middle of functional material clamping two glass, its concrete structure mode as shown in Figure 4.The former highly versatile, flexible and convenient to use, can on original door glass, paste, both structure differences, but effect is equivalent.

The base material of functional membrane is a polyester, utilizes the method for vacuum evaporation to obtain conducting film in a side of polyester film, functional material is uniformly coated in the middle of two polyester then, makes it after the pressurization to solidify, and the color and the thickness of its rete are controlled with filler.

When making base material with glass, it is complicated that technology is wanted.At first, with the method for float glass by dipping, topped sio on the surface ₂Anti-reflection protective film, so-called anti-reflection, refer to each reflecting surface concerning visible light, light transmittance can increase more than 8%; So-called protection refers to prevent that sodium, calcium ion in the alkali glass from going out so far.Then, the method with thermal spraying or vacuum evaporation obtains sno at glass surface ₂Or ln ₂o ₃Conducting film with above-mentioned method coating functional material, is made dimming glass again.

Carry out area dividing and carry out on conducting film, employing machinery is divided or the method for chemical corrosion can.To bond to each part of conductive region towards the contact conductor of controller one by one with conducting resinl simultaneously.

The functional high molecule material that dimming glass is related all is the fine chemical product that just was synthesized modern age, and functional material is mainly the mixture of A, B, three kinds of components of C.

A is a liquid crystal, and the difference of its non-ordinary light and ordinary light is more than 0.2, dielectric anisotropy be on the occasion of the time, when static (current potential is zero), be opaque state; During negative value, be clear state when static.

B is the high molecular polymer that refractive index and A are complementary.The ordinary refraction index value of polymer and liquid crystal is just high more near transparency more; The very optical index difference of polymer and liquid crystal is big more, and then light transmittance is high more relatively.See that at present the high molecular polymer that possesses this specific character is seldom generally chosen in epoxy resin, polyvinyl alcohol acetals.

C is that organic dyestuff and solid are dosed thing, require to have metastable characteristics, can not with above-mentioned two kinds of material generation chemical actions.
