Description

Technical Field

[0001] The utility model relates to the technical field of glass, in particular to a tempered abyss mirror coated glass. Background Art

[0002] At present, ordinary abyss mirrors on the market are made by combining two double-sided mirrors to achieve a deep effect. When two double-sided mirrors are pasted together to be used as an abyss mirror, there are the following problems: (1) When in use, the two double-sided mirrors need to be glued together with glass glue. The abyss mirrors made in this way are generally thicker, which has limited usage occasions and can only be used in occasions where thickness is not restricted; (2) The requirements for the adhesive are relatively high. After a long period of use, the two mirrors may separate due to aging of the adhesive, affecting the use and low safety; (3) However, when the required shape of the abyss mirror is more complex, such as when used in car interiors, abyss mirrors of different shapes are required, and the time cost of cutting and pasting the two double-sided mirrors is high; (4) The oxidation resistance and corrosion resistance of the double-sided mirror need to be improved.

[0003] Therefore, it is necessary to design a coated glass with a lower reflectivity on the glass surface and a higher reflectivity on the film surface, which can not only achieve a deep effect, but also is not restricted by the usage occasions, has low labor costs, is anti-oxidation and corrosion-resistant, and has guaranteed safety.

The utility model uses a variety of materials for alternating coating, so that the front and back sides of the single-piece glass have two reflectivities, one high and one low. The reflectivity of the glass surface is about 7%, the reflectivity of the film surface is about 66%, and the transmittance is about 11%, so that the glass has both a reflective effect and can transmit some light. Under the action of light, it achieves a deep effect while reflecting soft light. The glass film layer is tempered at a high temperature of 680 degrees, the film layer is not burned, the color is stable and changes little, and it has acid and alkali resistance.
