Hardened waterproof and oil-proof lens and manufacturing process thereof

Abstract

The invention discloses a hardened waterproof and oil-proof lens, which consists of a lens body and a hardened waterproof and oil-proof film layer. The manufacturing method includes: cleaning the lens body, soaking the lens body in a liquid-state hardening waterproof and oil-proof agent for 1-3 seconds, drying the soaked lens body in a drying furnace with the temperature of 85+ / -5 DEG C for 20 minutes directly, and obtaining the finished lens by the aid of the drying furnace or by drying the lens body naturally after standing for 1-2 hours at the normal temperature. The hardened waterproof and oil-proof lens requires few production devices, investment cost for the devices is reduced, the assorted device input is not higher than 200,000 RMB, production cost is reduced to be 0.5Yuan / pair, the manufacturing procedures are simplified, production efficiency is improved, the productivity of single unit can be 720 pairs / hour, energy economization and environmental protection are realized, the power consumption of the single unit is 10kW / H. In addition, surfaces of the lens produced by the manufacturing process are hardened, scratch-resistant, waterproof, oil-proof and the like, and the lens has the service life about one year.

Description

technical field [0001] The invention relates to a hardened waterproof and oil-proof lens and a manufacturing method thereof. Background technique [0002] Lenses are divided into sun lenses and optical lenses, and optical lenses include nearsighted lenses and farsighted lenses. Due to the functional requirements of various lenses, some will attach a polarizing film to the surface of the lens or sandwich a polarizing film in the middle of the lens to make it a polarized lens, and some add a colored factor to the lens to make it a colored lens, and some lenses A color-changing factor is added to make it a color-changing lens, and some are coated with a waterproof and oil-proof film on the surface of the lens to form a waterproof and oil-proof lens, and some lenses are made of special materials to have corresponding functions... [0003] Among them, the manufacturing method of the waterproof and oil-proof lens is: the lens body and the solid waterproof and oil-proof material a...

Problems solved by technology

The disadvantages of this manufacturing method are:

[0004] 1. The vacuum coating machine is expensive. The domestic machine is about 700,000 yuan / set, the imported machine is about 2 million yuan / set, and other supporting equipment is about 100,000 yuan. The investment cost is too high;

[0005] 2. During the production process, the vacuum coating machine needs to vacuum the inside of the machine and evaporate the waterproof and oil-proof materials, which consumes a lot of power. The average power consumption of a single machine is 50kW·H per hour, which does not comply with environmental protection policies;

[0006] 3. The processing cost is high, and a piece of waterproof and oil-proof material can only be used once;

[0007] 4. The process is complicated, the production efficiency is low, and the stand-alone production capacity is only 200 pay / hour

[0009] In view of this, the present inventor has researched on the surface of the existing lens that is easy to be scratched and easily polluted by water and oil, and has developed a hardened waterproof and oil-proof lens and its manufacturing method. This case arises from this
