[embodiment]
Fig. 1～Fig. 2 is the schematic diagram that the utility model table body is implemented the manufacture process of the liquid crystal film of anti-light evil.As shown in Figure 1, the utility model table body is implemented in the manufacture method of liquid crystal film of anti-light evil, first on the surface of a pair of transparent base 20, forms transparency electrode 22.Then, on transparent base 20, form after transparency electrode 22, after first UV cured epoxy resin 10, rigidizer 12, the liquid crystal material 14 with difunctionality base being mixed, utilize rigidizer 12 to change the stickiness of the UV cured epoxy resin 10 with difunctionality base, but can significantly not change the characteristic of UV cured epoxy resin 10, and can at room temperature can form liquid crystal colloid 16, and import surface with this of transparency electrode 22 between transparent base 20.So, can utilize passed into electric current to change the direction of liquid crystal colloid 16, and the effect of shading or not shading is provided.
In this process, because UV cured epoxy resin 10, rigidizer 12 can produce interlinkage reaction more than 5 degree Celsius, more than the viscosity of liquid crystal colloid 16 has 200cps, make viscosity and temperature association lower.This wherein, the principal ingredient with the UV cured epoxy resin 16 of difunctionality base is cyclohexanedimethanol glycidol ether (diglycidyl ether of Cyclohexane dimethanol).In addition, in liquid crystal colloid 16, there is UV cured epoxy resin 10, the rigidizer 12 of difunctionality base, the blending ratio of liquid crystal material 14 is 1:1:1 haply.Meanwhile, this also can guarantee that liquid crystal material 14 is dispersed in UV cured epoxy resin 10 and rigidizer 12 mixtures, and obtains the luminous flux of uniform refractivity and expectation, avoids liquid crystal material 14 concentrations together, affects the quality of liquid crystal film.Moreover, utilize rigidizer 12 to change the stickiness of the UV cured epoxy resin 10 with difunctionality base, and need not add again the material of anti-UV, and guarantee the stability of liquid crystal colloid 16, anti-the being subject to property of its environment is also stronger simultaneously.
The utility model table body is implemented the liquid crystal film of anti-light evil except the effect of shading or not shading can be provided; further carry out conservation treatment step; that is at least form the thin layer 26 of containing metal particle that can anti-light evil on to two of transparent base 20 outer surfaces on one of them surface at this, and utilize the thin layer 26 of containing metal particle to prevent the destruction that infrared ray, ultraviolet ray or light heat energy cause.
In the thin layer 26 of containing metal particle that can anti-light evil, how need can absorption or light reflection ultraviolet, infrared ray or light heat energy for rice metallics, but can allow visible ray penetrate, and do not have mirror effect, and taking into account is that inside and outside view is enjoyed.How to utilize the characteristic of rice metallics, can effectively block again molecular gap, allow gas be difficult to scattering and permeating, thereby improved the barrier of transparent base 20, can effectively protect inner liquid crystal material.
Above-mentioned metallics can be tungsten oxide (WO), titanium nitride (TiN), aluminium nitride (AlN), iron oxide (FeO), cesium oxide (CeO), vanadium oxide (VO), titania (TiO2), zinc paste (ZnO), indium oxide (In2O3), cerium oxide (CeO2), tin oxide (SnO2), antimony oxide (Sb2O3), zinc sulphide (ZnS), antimony tin oxide (ATO) or other similarity metal oxides.
This wherein, through how rice titanium nitride (TiN) of special process fabrication process, it has, and purity is high, particle diameter is little, be evenly distributed, surfactivity is high, high temperature resistant, anti-oxidant, hardness is high, there is again excellent intercept infrared ray (can intercept more than 95%) and ultraviolet ray (can intercept more than 99%), itself there is again good electric conductivity simultaneously, can not block or disturb e-Tag or GPS signal, be very suitable for windscreen for vehicle.Titanium nitride (TiN) can allow transparent base 20 possess original transparent appearance, but can improve 8 times of above barriers.If when the nitrogen content in titanium nitride (TiN) is high, titanium nitride (TiN) will be with light blue, and need not additionally use color condiment, just can allow film with color.
The means that form thin layer 26 on transparent base 20 are roughly divided into three kinds of coating, spraying, evaporations etc.While adopting coating means, above-mentioned metallics must mix with suitable high molecular polymer.The ethene of polyester based resin, polystyrene (PS) and polyvinyl alcohol (PVA) (PVA) that wherein high molecular polymer can be polyolefin-based resins, polyethylene terephthalate (PET) and the PEN (PEN) of tygon (PE) and polypropylene (PP) in conjunction with being, polycarbonate (PC) is resin, cyclic olefine resin, vinyl chloride-based resin.Then, the potpourri of metallics and high molecular polymer is coated on transparent base 20, then utilizes the means of solidifying of heating or ultraviolet light, and on transparent base 20, form thin layer 26.
While adopting spraying means, above-mentioned metallics is sprayed on transparent base 20 after mixing with organic solvent, and then utilizes the means of solidifying of heating or ultraviolet light, allows metallics and organic solvent be mixed to form the thin layer 26 of containing metal particle.
While adopting evaporation means, metallics is directly deposited on transparent base 20, and forms the thin layer 26 of this containing metal particle.
But, after above-mentioned liquid crystal film is folded into a certain degree, the liquid crystal in liquid crystal colloid 16 can be extruded, and causes the thickness of liquid crystal film to become inhomogeneous.In order to improve this problem, can add interval microstructure 15 at liquid crystal colloid 16.
As shown in Figure 2, implement in the manufacture process of liquid crystal film of anti-light evil at above-mentioned the utility model table body, in liquid crystal colloid 16, sneak into polystyrene (polystyrene) or mineral interval microstructure 15, and form final liquid crystal colloid 18.In final liquid crystal colloid 18, polystyrene (polystyrene) or mineral interval microstructure 15 have accounted for 0.5～5% ratio in weight, and polystyrene or mineral interval microstructure are the spheroidite of diameter 10～30 μ m.So, interval microstructure 15 with sneak into liquid crystal colloid 16 and can jointly form each other space network, under external force impact, still can maintain the thickness of liquid crystal film.
Thus, the utility model liquid crystal film is except utilizing the had mercy on characteristic of transparent base 20, can for example, stick up along the morphology of object (surface curvature or wavy) whole piece, and no longer needing as first difficult cutting into after several small pieces dimming films of known techniques needs, more bothersome the surface curvature or wavy on glass that is attached at respectively.Meanwhile, utilize and in liquid crystal colloid 16, sneak into interval microstructure 15, and avoid walking to become because liquid crystal is squeezed by bending time transparent, and then reach and maintain film dimensions stability, film forming uniformly, and the characteristic such as low-refraction.Relatively, why known techniques cannot be applicable to the attaching of surface curvature or wavy glass, exactly because its shortage can maintain film dimensions stability, and the interval microstructure 15 of the characteristics such as film forming, and low-refraction uniformly.
Can carry out implementation with polystyrene (polystyrene) or mineral particles in the utility model interval microstructure 15.In practical application, the light transmission of polystyrene is better, but that it holds film dimensions stability is poor, and the light transmission of mineral is poor, but that it holds film dimensions stability is better.Therefore in actual use, be, mainly to select according to the degree size of surface curvature or wavy glass the soft liquid crystal film that contains polystyrene (polystyrene) or mineral particles.
For example, in order to facilitate the utility model liquid crystal film to be attached to (on the glass or windshield of window) on transparent base, also need to provide adhesive coating 24.
Fig. 3～Fig. 4 is the schematic diagram that the utility model table body is implemented the liquid crystal film of anti-light evil.As shown in Fig. 3～Fig. 4, at the thin layer 26 of containing metal particle or do not have on the surface of transparent base 20 of the thin layer 26 of containing metal particle and be formed with adhesive coating 24.In other words; structure as shown in Figure 3; in the use; the thin layer 26 of containing metal particle will be on the glass or windshield of the most close for example window; therefore thin layer 26 can first filter out most of infrared ray, ultraviolet ray or light heat energy of injecting from outside, and then protects whole the each element of creation liquid crystal film.Structure as shown in Figure 4, in the use, the thin layer 26 of containing metal particle will be on the glass or windshield away from for example window, therefore 26 of thin layers can filter out the infrared ray, ultraviolet ray or the light heat energy that penetrate the each element of the utility model liquid crystal film, but can guarantee that infrared ray, ultraviolet ray or light heat energy can not inject in indoor or car.
