Embodiment 1

[0016] Embodiment 1: a kind of mobile phone lens processing method is characterized in that, comprises the following steps:

[0017] (1) Clean the surface of the mobile phone lens with acetone, distilled water, and ethanol respectively, spray the coating solution on the dried lens, and then put it in an oven at 80°C to dry. The coating solution can be sprayed and dried multiple times until the film thickness 1.5 μm;

[0018] (2) Put the mobile phone lens obtained in step (1) into a nitrogen atmosphere, raise the temperature to 240°C, keep it warm for 30 minutes, then cool it down to 183°C at a rate of 1.5°C / min, and then lower it to room temperature at a rate of 10°C / min , you can.

[0019] The preparation method of described coating liquid is:

[0020] (1) Add 10ml of 1,2-dodecanediol and 10ml of octadecene into a three-necked flask, add a magnetic stirrer at the same time, and feed argon before heating to ensure that the reaction is in an anhydrous, anhydrous In an oxygen...

Embodiment 2

[0024] Embodiment 2: the difference with embodiment 1 is:

[0025] The preparation method of described coating liquid is:

[0026] (1) Add 10ml of 1,2-dodecanediol and 10ml of octadecene into a three-necked flask, add a magnetic stirrer at the same time, and feed argon before heating to ensure that the reaction is in an anhydrous, anhydrous In an oxygen environment, then turn on the magnetic stirrer, heat the reactant to 140°C, keep it warm for 1 hour, then raise the solution temperature to 250-260°C;

[0027] (2) Inject 10ml of oleic acid, 5ml of octadecene, 1mmol of zinc stearate, and 0.4mmol of gallium acetylacetonate into the three-necked flask, and at the same time lower the temperature to 230°C, keep it warm at 230°C for 1.5h, and stop feeding argon Add cis-2-butene to the reaction liquid, continue to keep warm at 230°C for 1 hour, then turn off the magnetic stirrer, stop feeding cis-2-butene, and cool the solution accordingly;

[0028] (3) Transfer the reacted solutio...

Embodiment 3

[0031] Embodiment 3: the difference with embodiment 1 is:

[0032] The preparation method of described coating liquid is:

[0033] (1) Add 10ml of 1,2-dodecanediol and 10ml of octadecene into a three-necked flask, add a magnetic stirrer at the same time, and feed argon before heating to ensure that the reaction is in an anhydrous, anhydrous In an oxygen environment, then turn on the magnetic stirrer, heat the reactant to 140°C, keep it warm for 1 hour, then raise the solution temperature to 250-260°C;

[0034] (2) Inject 10ml of oleic acid, 5ml of octadecene, 1mmol of zinc stearate, and 0.4mmol of gallium acetylacetonate into the three-necked flask, and at the same time lower the temperature to 230°C, keep it warm at 230°C for 1.5h, and stop feeding argon Gas, pass cyclopropane into the reaction solution, continue to keep warm at 230 ° C for 1 hour, then turn off the magnetic stirrer, stop passing cyclopropane, and cool the solution accordingly;

[0035] (3) Transfer the rea...

Abstract

The invention provides a mobile phone lens processing method. A gallium-doped zinc oxide coating material is prepared by controlling the reaction conditions, the average transmittance of the gallium-doped zinc oxide coating material in a visible light region is more than 95%, and the antireflection effect is good. In the preparation process of a coating solution, a certain amount of cis-2-butene and cyclopropane are introduced, the anti-reflection performance and the stain resistance of a mobile phone lens after coating can be remarkably improved, and the performance and the anti-fouling effect of the mobile phone lens are improved. In addition, in the coating process of the mobile phone lens, a unique annealing mechanism is adopted, the temperature is increased to 240 DEG C and the temperature is kept for 30 minutes, and then the temperature is reduced to 183 DEG C with a rate of 1.5 DEG C / min, and then reduced to the room temperature with a rate of 10 DEG C / min. The cooling rate anda temperature node of 183 DEG C are critical; and by adopting the cooling process disclosed by the invention, the film surface roughness and microcracks can be reduced, so that the aging resistance ofthe mobile phone lens after coating is greatly improved.

Description

technical field [0001] The invention relates to a mobile phone lens processing method, which belongs to the technical field of lens processing. Background technique [0002] With the popularization of mobile phones, people's requirements for various performances of mobile phones are also gradually increasing, especially the camera and camera performance of mobile phone lenses, which not only require high-quality, high-resolution photos, but also require that they can adapt to various a working environment. [0003] When light passes through different media, reflection and refraction will occur. However, modern mobile phone lenses have more complex structures and more lenses, so the number of reflections and refractions that occur after light enters the lens will increase. This will lead to two problems: one is that there will be a greater loss of light passing through the lens; Very effective in improving these problems. Coating is a very thin transparent film coated on t...
