Problems solved by technology

[0004] There are following deficiencies in the lenses prepared according to the steps of the traditional process and the equipment and methods used: although the surface of the obtained lenses is easy to clean, and can also be simple to prevent oil and water, but in seawater (5% concentration of sodium chloride) After soaking in medium for 24 hours, the surface color will partially fall off, and after soaking for 48 hours, the surface color will fall off seriously, and the initial water drop angle value will also drop significantly, so the follow-up friction resistance (steel wool / eraser) test cannot be carried out

Embodiment 1

[0096] Step 1), performing plasma bombardment on the surface of the lens to activate the substrate, and for the glass lens, the water drop angle value is lower than 15° after plasma bombardment;

[0097] Step 2), prepare the coating material, adopt ion-assisted plating, and adjust the thickness of the film layer according to different color requirements (made by TFC simulation);

[0098] Step 3), anti-evaporation evaporation waterproof film;

[0099] Step 4), the electron gun evaporates AF;

[0100] Step 5), stand still.

[0101] Figure 5 It is a comparison chart of lenses treated by the process of Example 1 after soaking in seawater for different times.

[0102]

[0103] The advantage data of embodiment 1 relative comparative example 1-4:

[0104] 1. The overall initial water drop angle value is about 2° higher. This method evaporates AF, and the evaporation is more complete. The thickness of the film layer will be thicker than the above method, and there will be no l...

Abstract

The invention provides a lens optical coating surface treatment process and a lens obtained by the process. The process comprises the following steps of (1), performing plasma bombardment on the surface of the lens to activate a substrate; (2), preparing a coating material, specifically, ion-assisted plating is adopted; (3), performing electron beam evaporation plating to obtain a waterproof film;(4), preventing evaporation AF; and (5) standing. The process is simple, the properties of all aspects of the obtained lens are improved, and new technical requirements can be met. The obtained lens(such as a sunglass lens) is easy to clean, good in waterproof and antifogging performance and not likely to scratch, and the service time of the obtained lens is prolonged.

Description

technical field [0001] The invention relates to the field of glasses, in particular to a lens optical coating surface treatment process and a lens obtained through the process. Background technique [0002] In the prior art, in order to achieve the different colors of the lens and achieve the effect of waterproofing, it is necessary to evaporate the color (filter, cut-off) or coating AR anti-reflection on the surface of the lens respectively. Through this evaporation method, the coating The color is produced, and then a waterproof film is evaporated on the surface. It can play different colors or colorful effects of glasses, and the surface can meet the technical requirements of waterproof and anti-fouling, seawater immersion and corrosion. [0003] The treatment process mainly includes: product surface plasma cleaning + evaporation color + evaporation waterproof film + performance test [0004] There are following deficiencies in the lenses prepared according to the steps...
