Preferably, the step S2 is specifically included:
Step S21, the titanium film of a first thickness is deposited in the glass body upper surface；
Step S22, the silicon thin film of a second thickness is deposited above the titanium film；
Step S23, the chromium thin film of a third thickness is deposited above the silicon thin film.
Preferably, the step S3 are as follows: ink is sprayed to the chromium thin film surface layer by spraying method.
Preferably, the range of the roughness of the pretreated glass body is between Ra0.04~Ra0.06 μm.
Preferably, the first thickness, the second thickness and the third thickness Set scale are according to the darkroom glass
Reflectivity needed for glass and transmitance determine.
Preferably, the range of the reflectivity is between 20%~30%, and the range of the light transmittance is 50%~70%
Between.
Preferably, the ink is the ink for the bi-component reaction-type that epoxy resin and synthetic resin are deployed into.
A kind of darkroom glass includes glass body, photic zone and ink, the ink, the photic zone and the glass sheet
Body from top to bottom successively stacks, and for the photic zone vapor deposition in the glass body upper surface, the ink is sprayed at the light transmission
Layer upper surface.
Preferably, the photic zone includes titanium film, silicon thin film and chromium thin film, the titanium film, the silicon thin film and institute
It states chromium thin film successively to cover layer by layer from the bottom to top, the titanium film is covered on the glass body.
Preferably, the transparency of the darkroom glass is determined jointly by the thickness of the photic zone and the ink, described
The range of transparency is between 15%~30%.
Compared with prior art, the invention has the following beneficial effects: pass through the glass of PVD evaporation process after the pre-treatment
Body surface plates one layer of photic zone, stops the light transmittance reduction of glass body itself to pass through, the effect of reflection is increased, to make
Obtain the effect for thering is mirror surface to show under available light；One layer of translucent ink is covered in light transmission layer surface, indoors under light
It can see translucent effect.
Detailed description of the invention
Fig. 1 is the flow chart of the processing method of darkroom of embodiment of the present invention glass.
Fig. 2 is the structural schematic diagram of darkroom of embodiment of the present invention glass.
Fig. 3 is the enlarged drawing of part A in Fig. 2.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Darkroom glass can have different display effects under different light conditions.Fig. 1 is darkroom of embodiment of the present invention glass
Processing method flow chart, be described in detail according to processing method of the Fig. 1 to darkroom glass:
As shown in Figure 1, the processing method of darkroom glass of the invention is can have under different light conditions for manufacturing
Different display function darkrooms glass, specifically, this method comprises the following steps:
Step S1, the pretreatment that glass body surface is ground and polished；
Step S2, one layer of photic zone is plated on glass body surface after the pre-treatment；
Step S3, one layer of translucent ink is covered in light transmission layer surface.
During making darkroom glass, the pre- place that the glass body surface cleaned up need to be ground and be polished
Reason, primarily to reducing the roughness on glass body surface.
Roughness is that glass body is ground and the finish effect of surface of polished, glass body surface instrument amplification
When measurement, surface can be appreciated that there are still there is a rough effect, and the height data that apparatus measures obtain are roughness Ra,
Ra numerical value is smaller, and surface will be more flat, and finish is better, the range of the roughness of pretreated glass body in the present invention
Between Ra0.04~Ra0.06 μm, the smooth and bright like a mirror face in glass body surface at this time.
After completing the pretreatment of glass body, further, the glass body of PVD evaporation process after the pre-treatment is utilized
Plate one layer of photic zone in surface.The photic zone is non-conductive chemical substance.Specifically, thick in glass body upper surface vapor deposition one first
The titanium film of degree, is deposited the silicon thin film of a second thickness above titanium film, and the chromium of a third thickness is deposited above silicon thin film
Film.Preferably, the thickness of plated film be respectively titanium film first thickness range between 30~40nm, the second of silicon thin film is thick
Range is spent between 60~80nm, and the third thickness range of chromium thin film is between 80nm~120nm.First thickness, second thickness
And the specific Set scale of third thickness reflectivity according to needed for the glass of darkroom and transmitance determine, darkroom glass of the invention
It is required that reflectivity range between 20%~30%, the range of light transmittance is between 50%~70%.By euphotic
Design can stop the light transmittance of glass product itself, increase the effect of reflection.
Finally, by spraying method to euphotic chromium thin film surface layer spray ink, ink to cover euphotic brightness,
So as to generate the effect penetrated for stopping light.Preferably, ink is the bi-component that epoxy resin and synthetic resin are deployed into
The ink of response type.
Based on the processing method of above-mentioned darkroom glass, the invention also discloses the darkroom glass made of the processing method
100, Fig. 2 be the structural schematic diagram of darkroom of embodiment of the present invention glass, and Fig. 3 is the enlarged drawing of part A in Fig. 2.According to fig. 2, Fig. 3
The structure of the darkroom glass 100 is described in detail:
Darkroom glass 100 of the invention include glass body 10, photic zone 20 and ink 30, ink 30, photic zone 20 and
Glass body 10 from top to bottom successively stacks, and photic zone 20 is deposited in 10 upper surface of glass body, and ink 30 is sprayed at photic zone
20 upper surfaces.Photic zone 20 includes titanium film 21, silicon thin film 22 and chromium thin film 23, titanium film 21, silicon thin film 22 and chromium thin film 23
It successively covers layer by layer from the bottom to top, titanium film 21 is covered on glass body 10.Finally, the transparency of darkroom glass 100 is by saturating
The thickness of photosphere 20 and ink 30 determines that the range of transparency is between 15%~30% jointly.
Compared with prior art, the invention has the following beneficial effects: pass through the glass of PVD evaporation process after the pre-treatment
One layer of photic zone 20 is plated on 10 surface of ontology, stops the light transmittance reduction of glass body 10 itself to pass through, increases the effect of reflection,
So that the effect for thering is mirror surface to show under available light；One layer of translucent ink 30 is covered on 20 surface of photic zone,
It can be seen that translucent effect under indoor light.
