Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a coated metal texture lens. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the aesthetics and functionality of glasses. Many customers hope that the lenses can have a metallic texture and anti-reflection function at the same time, so that they will not be affected by strong reflections when wearing glasses in strong sunlight and when taking photos and videos, and the aesthetics can be improved. However, current glasses cannot have both metallic texture and anti-reflection function, and cannot meet the needs of consumers. Utility Model Content

[0003] The purpose of the present invention is to provide a coated metal texture lens, which overcomes the above-mentioned defects and has a metallic texture and an anti-reflection function.

[0004] In order to achieve the above objectives, the solution of the present invention is:

[0005] A coated metal texture lens comprises a substrate, a nickel-chromium material layer, a silicon dioxide film layer and a titanium pentoxide film layer. The nickel-chromium material layer is coated on one side of the substrate, and the silicon dioxide film layer and the titanium pentoxide film layer are alternately coated on the side of the nickel-chromium material layer away from the substrate.

[0006] Furthermore, the silicon dioxide film layer is plated between the substrate and the nickel-chromium material layer.

[0007] Furthermore, a strengthening layer is plated between the substrate and the silicon dioxide film layer, and the strengthening layer is composed of a mixture of alcohol ether and silane.

[0008] Furthermore, the thickness of the strengthening layer is 1-10 μm.

[0009] Furthermore, there are 6 to 10 layers of silicon dioxide film layers, nickel-chromium material layers and titanium pentoxide film layers in total.

[0010] Furthermore, the total thickness of the silicon dioxide film layer, the nickel-chromium material layer and the titanium oxide film layer is 1600-2800 nm.

[0011] Furthermore, a strengthening layer is plated between the substrate and the nickel-chromium material layer, and the strengthening layer is made of a mixture of alcohol ether and silane.

[0012] Furthermore, the thickness of the strengthening layer is 1-10 μm.

[0013] Furthermore, it also includes a waterproof layer, which is plated on the side of the titanium pentoxide film layer or the silicon dioxide film layer away from the substrate.

[0014] Further, the substrate is made of resin and has a thickness ranging from 1 to 10 mm.

[0015] After adopting the above solution, the beneficial effects of the present utility model are as follows:

[0016] On one side of the substrate of the present utility model, a nickel-chromium material layer is plated. By means of the nickel-chromium material layer, the transmittance of the substrate is reduced, making it difficult for light to pass through the substrate, thereby brightening the lens and giving the lens a metallic texture effect. On the side of the nickel-chromium material layer away from the substrate, a silicon dioxide film layer and a titanium pentoxide film layer are alternately plated. The silicon dioxide film layer and the titanium pentoxide film layer have an antireflection effect, reducing light reflection, enabling the lens to have antireflection and presenting a brighter effect. Therefore, the lens of the present utility model can have both a metallic texture and an antireflection function. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0023] As Figure 1As shown in the figure, the present utility model provides a coated metal texture lens, which includes a substrate 1, a nickel-chromium material layer 2, a silicon dioxide film layer 3, and a titanium pentoxide film layer 4. Among them, the nickel-chromium material layer 2 is plated on one side of the substrate 1, and the silicon dioxide film layer 3 and the titanium pentoxide film layer 4 are alternately plated on the side of the nickel-chromium material layer 2 away from the substrate 1. By the nickel-chromium material layer 2, the transmittance of the substrate 1 is reduced, making it difficult for light to pass through the substrate 1, thereby brightening the lens and making the lens produce a metallic texture effect. And on the side of the nickel-chromium material layer 2 away from the substrate 1, the silicon dioxide film layer 3 and the titanium pentoxide film layer 4 are plated. The silicon dioxide film layer 3 and the titanium pentoxide film layer 4 have an antireflection effect, reducing light reflection, enabling the lens to have antireflection, and enabling the lens to present a brighter effect. Therefore, the lens of the present utility model can have both metallic texture and antireflection functions.

[0024] As Figure 2 shown, further, a strengthening layer 5 is plated between the substrate 1 and the nickel-chromium material layer 2. The strengthening layer 5 is made of a mixture of alcohol ether and silane, and its thickness is 1 - 10 μm. The strengthening layer 5 helps to increase the surface hardness of the lens, making the lens resistant to friction and not easily scratched, and making the lens have a longer service life.

[0025] Specifically, the material of the substrate 1 is resin, and its thickness range is 1 - 10 mm, such as nylon, etc.

[0026] As Figure 3 shown, in one embodiment, the silicon dioxide film layer 3 is plated between the substrate 1 and the nickel-chromium material layer 2. This silicon dioxide film layer 3 is located between the nickel-chromium material layer 2 and the substrate 1, and can play the roles of enhancing film layer adhesion, protection, and facilitating stripping. When the lens is pushed, with this silicon dioxide film layer 3, it is convenient to remove the film layer with a stripping solution, without damaging the substrate 1 or leaving film layer residues.

[0027] Specifically, the total number of the silicon dioxide film layer 3, the nickel-chromium material layer 2, and the titanium pentoxide film layer 4 is 6 - 10 layers, and their total thickness is 1600 - 2800 nm.

[0028] When manufacturing the lens of this embodiment, in the first step, the substrate 1 is placed in an oven and baked at 55 degrees for 5 hours and then arranged in a row. In the second step, after evacuating to about 15 minutes until the vacuum degree reaches 6.0×10⁻⁵ Torr, argon is filled and the surface is cleaned with an ion gun for 120 seconds. In the third step, continue to evacuate for about 5 minutes until the vacuum degree reaches 3.0×10⁻⁵ Torr and then coat the film:

[0029] (1) Coat the silicon dioxide film layer 3 with a thickness of 500 nm with a current of 80 A;

[0030] (2) Coat the nickel-chromium material layer 2 with a thickness of 180 nm with a current of 65 A;

[0031] (3) Oxygen is filled at 53 sccm, and a 100-nm titanium pentoxide film layer 4 is plated with a current of 280 A;

[0032] (4) A 200-nm silicon dioxide film layer 3 is plated with a current of 80 A;

[0033] (5) Oxygen is filled at 53 sccm, and a 680-nm titanium pentoxide film layer 4 is plated with a current of 280 A;

[0034] (6) A 560-nm silicon dioxide film layer 3 is plated with a current of 80 A.

[0035] Specifically, the total film layer thickness of this embodiment is 2220 nm; specifically, the total film layer thickness is automatically controlled by machine settings. The change in thickness can change the color and can also be adjusted according to the needs of subsequent processing, with high flexibility.

[0036] As Figure 4 shown, further, a strengthening layer 5 is plated between the substrate 1 and the silicon dioxide film layer 3. The strengthening layer 5 is composed of a mixture of alcohol ether and silane, with a thickness of 1 - 10 μm. The strengthening layer 5 helps to increase the surface hardness of the lens, making the lens resistant to friction and not easily scratched, and making the lens have a longer service life;

[0037] Further, it further includes a waterproof layer 6. The waterproof layer 6 is plated on the side of the titanium pentoxide film layer 4 or the silicon dioxide film layer 3 away from the substrate 1. The waterproof layer 6 can prevent a large number of pore-like structures on the film layer surface from being contaminated by grease and dust, and can increase the wetting angle of water droplets on the film layer surface, facilitating cleaning.
