Embodiment Construction

[0021] Such as Figure 1-2 As shown, the lens surface 1 is micromachined by laser micromachining to obtain a mirror surface with uniformly arranged columnar structures 2, the diameter of the columns is 10-15 microns, the pitch is 20-30 microns, and the height is about 60-70 microns. Between the body is the air cushion 3. Then a layer of nanostructure is constructed by combining microstructure with alkyl ketene dimer (AKD) treatment. AKD is uniformly distributed on the microprocessed surface in the form of particles, and the particle size is about 130 nm, so that the lens forms a contact angle of 4 The imitation lotus leaf super-hydrophobic mirror surface is greater than 140 degrees. The columnar structure 2 has a large relative column height (Hr=2), which can ensure a composite wet state and a small relative column width (0.33≤Ar≤0.75), and can obtain a contact angle of not less than 140 degrees. And a layer of air cushion 3 is formed in the columnar groove to further reduce...

Abstract

The invention discloses an anti-fog self-cleaning lens and a preparation method thereof. Columnar structures are uniformly arranged on the surface of the lens, and each columnar structure is composed of column bodies which are 10-15 microns in diameter and arranged at an interval of 20-30 microns; granular alkyl ketene dimers are uniformly distributed on the surfaces of the columnar structures so as to form a nanostructure. According to the method, columnar structures are formed on the surface of the lens through laser micro processing, and in combination with alkyl ketene dimers, a nanostructure is formed, so that a water droplet forms a contact angle of over 140 DEC on the surface of the lens, and then the water droplet can not be standing on the surface of the lens, thereby preventing the formation of fog on the surface of the lens better. In such a way, the lens provide clearer and more stable vision for people wearing glasses, thereby greatly facilitating the daily life of people wearing glasses. Once the structure is formed, additional measures such as a measure of adding an antifoggant repeatedly are not required to be taken, so that the lens can be durably used.

Description

technical field [0001] The invention relates to the fields of lens manufacturing and laser microprocessing, in particular to a method for preparing an anti-fog self-cleaning lens. Background technique [0002] In daily life, fog is everywhere, and the application of anti-fog glasses is becoming more and more extensive. Ordinary glasses wearers, doctors, drivers, swimmers and deep-sea diving operators all need to use them, so anti-fog lenses and anti-fog glasses have been produced. Multiple applications for laryngoscopes, anti-fog masks, etc. [0003] The earliest anti-fog lens is mainly to set a heat-insulating ring between the two layers of lenses and glue them together. The heat-insulating ring forms an isolation chamber between the two layers of lenses. The isolation chamber is evacuated to block Most of the heat conduction, but such anti-fog lenses are extremely thick and unsightly, not suitable for ordinary consumers to wear. Then a kind of anti-fog lens realized by c...
