Abstract
The invention discloses automotive color-changing glass. The automotive color-changing glass is prepared by adding a compound of silver and halogen and trace copper oxide into a common glass raw material, wherein the copper oxide is a catalyst. The principle of the color-changing glass mainly depends on a special chemical reaction between the compound of the silver and the halogen as well and the trance copper oxide and ultraviolet rays. When the color-changing glass is exposed in the ultraviolet rays of sunshine, silver halide in the color-changing glass decomposes to produce the silver and the halogen and absorbs part of the visible light, so that the glass looks dim, namely the color darkens. When the color-changing glass leaves the radiation of the ultraviolet rays, corresponding chemical inverse change happens and molecules are recovered to original structure rapidly, so the glass changes light until colorless and transparent.
Description
Technical field
The present invention relates to a kind of automotive color-changing glass product and preparation method thereof, particularly a kind of with in the simple glass raw material, add silver atoms and halogen compound---Silver monobromide etc. are automotive color-changing glass product of matrix and preparation method thereof with micro-cupric oxide, are used for automobile and prevent strong ultraviolet radiation etc.
Background technology
Existing vehicle glass, because its lucifuge poor performance, when automobile be placed on the open air particularly the following residence time of strong ultraviolet radiation long a bit after into the car the time, very high in the car owing to ultraviolet irradiation temperature, car interior trim epidermis even very boiling hot is to window to turn on the aircondition also to need a very long time to feel nice and cool.And when ultraviolet ray is very strong, drive, it is very uncomfortable that eyes are stimulated by high light, generally wants blink.Not only influence sight line but also influence safety, more can not drive for a long time.Above drawback is sticked best solar film and is not also played much effects, and in use, need be manipulation, extremely inconvenient, be necessary to make improvements.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides and a kind ofly can effectively prevent strong ultraviolet radiation, long service life, can ensure safety and automotive color-changing glass product that production cost is low and preparation method thereof.
The present invention for the technical scheme that solves its technical problem and take is: except making the raw material of simple glass, add silver and becomes photo chromic glass with the compound of halogen with micro-oxidation copper in the simple glass raw material.The principle of photo chromic glass mainly depends on compound and micro-cupric oxide and ultraviolet a kind of special chemical reaction of silver and halogen.
Advantage of the present invention and beneficial effect are: vehicle glass is all made of off-color material, and the transmittancy that makes vehicle glass changes voluntarily with the power of extraneous sunlight.Glass colour deepens the irradiation with shielding of ultraviolet when light is strong; Glass colour is thin out when a little less than the light.Stop under burning sun so exactly, vehicle interior temperature can be very not high yet, and the light in the car can become soft and shady and cool sense is arranged; eyes can the photophobia blink yet during driving; have the effect protection eyes of light-sensitive glasses on the contrary, feel well, improve the driving security and prolong the driving time.And the directly deepening under uviolizing of this glass, the photochromic variation of recovering lost eyesight again after removing ultraviolet ray can again and again constantly go on, and can not produce catabiosis.Therefore, have long service life, the low characteristics such as safety coefficient that increase car steering that reach of production cost.
Embodiment
A kind of automotive color-changing glass product is that a kind of compound and micro-cupric oxide with adding silver and halogen in frit is that matrix is made.Below, the present invention is described in more detail, but, is not limited in following examples as long as in main idea scope of the present invention by implementing.
Embodiment:
A kind of automotive color-changing glass is that adding silver is made with the compound and the micro-cupric oxide of halogen in the simple glass raw material.Cupric oxide is a catalyzer.The principle of photo chromic glass mainly depends on compound and micro-cupric oxide and ultraviolet a kind of special chemical reaction of silver and halogen.Contain the molecule of silver halide in the photo chromic glass, silver halide is seen photolysis, and when not having uviolizing, visible light can penetrate these molecules, and the visible light general integral part of source of artificial light just.But when the ultraviolet following time that is exposed to sunlight, these molecules will be through a chemical process, making their shape change---generation silver and halogen take place to decompose in silver halide wherein, and with the form of the silver-colored particulate of various black, be evenly distributed in and absorb a part of visible light in the glass, it is dim that therefore glass seems, stops that light is current, and Here it is darkens.
The molecular amounts that shape changes can change along with the variation of uitraviolet intensity.
When leaving ultraviolet irradiation, under the effect of copper oxide catalyst, corresponding chemical inversionization will take place, these molecules will return to original structure rapidly---and silver and halogen regroup, generate silver halide, and silver halide is water white crystal, simultaneously because because silver halide does not absorb ultraviolet ray, glass absorbs this characteristic of light thereby lose, so can shoal until water white transparency again.
The variable color speed of photo chromic glass is relevant with uitraviolet intensity with depth degree.The strong more variable color speed of ultraviolet ray is fast more, otherwise speed is slow more.
Claims (2)
1. automotive color-changing glass product, be that adding silver is made with the compound and the micro-cupric oxide of halogen in the simple glass raw material, it is characterized in that: when the ultraviolet following time that is exposed to sunlight, these molecules will be through a chemical process, make their shape wherein the silver halide that changes take place to decompose and produce silver and halogen, and with the form of the silver-colored particulate of various black, be evenly distributed in and absorb a part of visible light in the glass, it is dim that therefore glass seems, stop that light is current, Here it is darkens.
2. a kind of automotive color-changing glass product according to claim 1, it is characterized in that: when leaving ultraviolet irradiation, under the effect of copper oxide catalyst, corresponding chemical inversionization will take place, these molecules will return to original structure rapidly---and silver and halogen regroup, generate silver halide, and silver halide is water white crystal, simultaneously because because silver halide does not absorb ultraviolet ray, glass absorbs this characteristic of light thereby lose, so can shoal until water white transparency again.
