Problems solved by technology

However, in daily life, the use rate of silver mirrors is high, and a simple protective layer is difficult to prevent oxygen in the air from entering the silver layer for a long time.
In addition, because the non-reflective surface is not directly in contact with the outside world, manufacturers often choose to ignore it, and use a relatively simple protective layer structure design, which makes the non-reflective surface easier to be scratched by foreign foreign substances such as dust and make the air Oxygen can easily enter the silver layer and cause it to be oxidized. Due to the appearance of a large amount of silver oxide after the silver layer is oxidized, the reflectance of the silver layer is greatly reduced, thereby greatly reducing the service life of the product.

preparation example Construction

[0022] The present invention also comprises the preparation method of coated silver mirror, comprises the following steps:

[0023] a. cutting the glass substrate 1;

[0024] b. cleaning the glass substrate 1 after step a;

[0025] c. Plating a silver layer 3 , a transition layer 4 and a silicone oil layer 5 on one side of the glass substrate 1 processed in step b in sequence.

[0026] In addition, in the process of step c, an adhesion layer 2 is also provided between the glass substrate 1 and the silver layer 3. The adhesion layer 2 is plated on the glass substrate 1, and then the surface of the adhesion layer 2 is plated with the silver layer 3, Transition layer 4 and silicone oil layer 5.

[0027] Adhesion layer 2, silver layer 3, transition layer 4, and silicone oil layer 5 can be coated by vacuum magnetron sputtering, and the glass substrate 1 is cut first, which can reduce the later cutting process of the product and make the coated silver mirror The cutting part is p...

Embodiment 1

[0030] Composition of coated silver mirror:

[0031] Glass substrate: float glass with a thickness of 2.5mm;

[0032] Adhesion layer: nickel-chromium alloy layer with a thickness of 2.5nm;

[0033] Silver layer with a thickness of 70nm;

[0034] Transition layer: nickel-chromium alloy layer with a thickness of 300nm;

[0035] Silicone oil layer: a methyl silicone oil layer with a thickness of 200nm.

[0036] Preparation of coated silver mirror:

[0037] Take the 2.5mm float glass and cut it into the size required by the product, and clean the surface with inorganic acid, then fix it in the vacuum magnetron sputtering coating machine, and then set the nickel-chromium alloy target material of the adhesion layer After completion, perform magnetron sputtering coating on one side of the float glass, stop the coating operation when the coating thickness of the adhesion layer reaches 2.5nm, replace it with a silver layer target and start the coating operation again, and stop when...

Abstract

The invention discloses a film plated silver mirror. The film plated silver mirror comprises a glass base plate; one side of the glass base plate is provided with a silver layer, a transition layer, and a silicone oil layer successively; the combination effect of the silicone oil layer which is hard and compact in surface with the transition layer is capable of improving the scratch resistance andthe oxidation resistance of the film plated silver mirror. The invention also discloses a preparation method of the film plated silver mirror.

Description

technical field [0001] The invention relates to the field of silver mirrors, in particular to a coated silver mirror and a preparation method thereof. Background technique [0002] The use of mirrors in human society has a history of more than 3,000 years. With the continuous development of technology, from the early metal alloy mirrors to mercury mirrors, and now to various metal-plated mirrors, people have more and more requirements for the use of mirrors. high. Metal-plated mirrors usually include copper mirrors, zinc mirrors, aluminum mirrors, and silver mirrors, among which silver mirrors have the best imaging effect. Therefore, silver mirrors are widely used in furniture, handicrafts, decoration and other fields. In order to meet the production requirements of various silver mirrors for different purposes, many new manufacturing processes are also used in this field, such as chemical plating mirror method, vacuum mirror plating method, thermal spray coating method, l...
