Abstract
The utility model relates to a reflecting mirror. An AL layer is arranged on an optical glass substrate, and a Cr layer is arranged outside the AL layer. The reflecting mirror has good reflecting rate and good environmental durability. The reflecting rate of the reflecting mirror can reach more than 80%.
Description
Technical field:
The utility model relates to a kind of catoptron, and this catoptron is useful in automobile rearview mirror, automotive rear-view blind area synergy mirror.
Background technology:
Common automobile rearview mirror adopts the Cr plated film on substrate, or plated film Al improves reflectivity.Though plated film Cr environmental durability can be good, because the optical property of Cr material determines its reflectivity to have only 40%～60%, reflectivity is on the low side.Though plated film Al reflectivity height because Al corrodes by severe rugged environment conditions such as acid, alkali and moisture easily, cause using a period of time after performance descend the lost of life.
Particularly synergy mirror in backsight blind area is to the requirement height of reflectivity for existing rearview mirror, and automobile environment for use complicated condition requires more and more higher to environmental durability.1., improve the reflectivity of plated film Cr want that reaching these two kinds of performances just must overcome 2 problems:; 2., increase the environmental durability of plated film Al.
The utility model content:
The purpose of this utility model is: a kind of existing high reflectance is provided, the catoptron that good environmental durability can be arranged is arranged.
The technical solution of the utility model is as follows: it is characterized in that it is to be provided with the Al layer on the optical glass substrate, to be provided with Cr layer formation outside the Al layer.
The utlity model has following advantage: the utlity model has the good reflectivity of tool, environmental durability, reflectivity can reach more than 80%.

Label declaration: the reflectivity of 1 optical glass substrate, 2Al layer, 3Cr layer, 4 medium coating materials, 5 common plating Cr films, the reflectivity of 6 plated film schemes of the present invention.
Embodiment:
As Fig. 1～shown in Figure 5, the utility model catoptron is to be provided with the Al layer on the optical glass substrate, to be provided with the Cr layer to constitute outside the Al layer.The utlity model has the high advantage of reflectivity thereby make.
The arbitrary layer between optical glass substrate and the Al layer or between Al layer and Cr layer or outside the Cr layer two-layer arbitrarily or three layers be provided with the medium coating materials that is used to increase the two adhesion.
The deielectric-coating material includes but not limited to as SiO
2, Ti
2O
3Etc. medium coating materials used in the various optical coatings.Concrete method for making of the present utility model:
1, put into coating machine after optical glass substrate is cleaned up, coating machine plates earlier the medium coating materials on optical glass substrate after reaching the plated film condition.
2, the medium coating materials tighten connect plate the Al layer.
What 3, be right after on the Al layer plates a layer dielectric material.
4, the medium coating materials tighten connect plate the Cr layer.
5, plate a layer dielectric material what Cr layer skin was right after.
As shown in Figure 6, the utility model has better reflecting effect compared with general catoptron, and reflectivity can reach more than 80%.
The utility model is mainly used but is not limited to comprise various catoptrons, automobile rearview mirror, automotive rear-view blind area synergy mirror.
Embodiment 1: be provided with the medium coating materials that is used to increase the two adhesion between optical glass substrate and Al layer.
Embodiment 2: only be provided with the medium coating materials between Al layer and Cr layer.
Embodiment 3: only the skin at the Cr layer is provided with the medium coating materials.
Embodiment 4: be equipped with the medium coating materials between optical glass substrate and the Al layer, between Al layer and Cr layer and at the skin of Cr layer.
Embodiment 5: be equipped with the medium coating materials between optical glass substrate and the Al layer and between Al layer and Cr layer.
Embodiment 6: be equipped with the medium coating materials between Al layer and Cr layer and at the skin of Cr layer.
Embodiment 7: be equipped with the medium coating materials between optical glass substrate and Al layer and at the skin of Cr layer.
