Abstract
The invention discloses a kind of anti-dazzling glasss for vehicle window, include consisting of (weight %): sodium aluminium borate 55-70%, silver halide 10-13%, silver halide is added in sodium aluminium borate and makees emulsion by copper ion 8-15%, cadmium ion 1-2%, it adds copper ion and cadmium ion makees sensitizer, after being melting into glass, it is heat-treated through 300 DEG C of temperatures above, silver halide is polymerized to microgranular.Anti-dazzling glass for vehicle window of the present invention can flexibly change the light transmittance of glass for vehicle window under different light, to achieve the purpose that prevent driver from dazzling the eyes in sunburst irradiation, play the role of improving driver's drive safety.
Description
Technical field:
The present invention relates to a kind of anti-dazzling glasss for vehicle window, belong to glass for vehicle window technical field.
Background technique:
Vehicle glass is to primarily serve protective action as part essential in automobile body accessories.Automobile at present
With glass, based on interlayer tempered glass and sandwiched area tempered glass, impact resistance is stronger.
In routine use, one layer of solar film is sticked on vehicle front and rear windshield, side window glass and skylight glass is
Conventional selection.The measure energy hermetic section ultraviolet light and heat, effectively prevent splashing glass to hurt sb.'s feelings, but there are still anti-dazzle abilities
Insufficient problem.Especially morning and dusk, the sun slants the eyes into driver at this time, be easy to cause and dazzles the eyes problem, generates
Security risk.
Summary of the invention:
The present invention is to provide a kind of anti-dazzling glass for vehicle window to solve the above-mentioned problems of the prior art, will be passed
System vehicle glass is changed to photo chromic glass.
The technical solution adopted in the present invention has: a kind of anti-dazzling glass for vehicle window, includes consisting of (weight %): sodium aluminium
Silver halide is added in sodium aluminium borate and makees by borate 55-70%, silver halide 10-13%, copper ion 8-15%, cadmium ion 1-2%
Emulsion, adds copper ion and cadmium ion makees sensitizer, after being melting into glass, is heat-treated through 300 DEG C of temperatures above, silver halide
It is polymerized to microgranular.
The invention has the following beneficial effects: anti-dazzling glasss for vehicle window of the present invention flexibly to change vehicle under different light
The light transmittance of glass pane plays raising driver and drives to achieve the purpose that prevent driver from dazzling the eyes in sunburst irradiation
Sail the effect of safety.
Specific embodiment:
Anti-dazzling glass for vehicle window of the present invention, it includes consisting of (weight %): sodium aluminium borate 55-70%, silver halide
10-13%, copper ion 8-15%, cadmium ion 1-2%.The present invention by sodium aluminum borate glass be added silver halide make it is photosensitive
Agent, adds copper ion and cadmium ion makees sensitizer, after being melting into glass, is heat-treated through appropriate 300 DEG C of temperatures above, makes halogenation
Silver is polymerized to microgranular and obtained, referred to as silver halide glass.When it is irradiated by ultraviolet light or visible light shortwave, silver ion reduction is
Silver atoms, several silver atoms are gathered into colloid and glass are made to develop the color；After illumination stops, in heat radiation or the long glistening light of waves, (feux rouges is red
Under irradiating outside), silver atoms become silver ion and fade.Such glass has two different configuration states, has in visible region
Two different absorption coefficients.The light absorption of visible light region can be generated under the visible light action of ultraviolet light or specific wavelength,
To be transformed into another structure from a kind of structure, the light transmittance of glass is caused to reduce or occur color change.And in illumination
Original pellucidity can be automatically restored to after stopping again.Anti-dazzling glass for vehicle window of the present invention is not easily tied, and can undergo 30
Ten thousand times or more light and shade variations.
Therefore, if automotive window use photo chromic glass, light brighter areas when driving, pass through glass discoloration reduce glass
Glass light transmittance enhances anti-dazzle light ability, reduces accident rate.In the more darker region of light, glass become again it is transparent, to drive
Person provides the clearly visual field.
The present invention adds copper ion, cadmium ion is made by making emulsion a small amount of silver halide is added in Conventional glass
Sensitizer after being melting into glass, is heat-treated through appropriate 300 DEG C of temperatures above, is polymerized to silver halide microgranular, will conventional automobile-used glass
Photo chromic glass is made in glass.Under the performance for not influencing Conventional glass, when ambient change is strong, photo chromic glass darkens, thoroughly
Luminosity reduces；When ambient dies down, photo chromic glass color bleach, light transmittance is got higher.The light transmittance of vehicle glass with
Ambient flexibly changes, to prevent driver from generating the case where dazzling the eyes.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
