Description

Technical Field

[0001] This invention belongs to the field of resin lens technology, specifically, it relates to a polarizing resin lens and its manufacturing process. Background Technology

[0002] A polarizing lens is a lens that allows only light of a specific polarization direction to pass through. Due to its filtering effect, things appear darker after passing through a polarizing lens. To filter the glare of sunlight shining on water, land, or snow from the same direction, a special coating is added to the lens perpendicular to the polarization direction; this is called a polarizing lens. The effect of a polarizing lens is to effectively eliminate and filter scattered light from a beam of light, much like the principle of Venetian blinds, adjusting the light so that it enters the room in the same direction, making objects appear soft and not glaring.

[0003] Most current polarized lenses have a polarizing film adhered to the front surface of a resin lens. Over time, this polarizing film is prone to peeling off, affecting not only the polarization effect but also the lens's transmission. Therefore, a polarized lens that is less prone to peeling is needed. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a polarizing resin lens and its preparation process, so as to avoid the trouble of easy peeling and low durability of previous polarizing lenses.

[0005] To address the aforementioned technical problems, this invention discloses a polarizing resin lens, comprising:

[0006] Polarizing film, the polarizing film has a sandblasted layer;

[0007] The front resin substrate and the back resin substrate are cured on both sides of the polarizing film;

[0008] Hardening layers dipped onto the surfaces of the front and rear resin substrates;

[0009] A photocurable protective layer spin-coated onto the surface of the hardened layer;

[0010] Antireflective layer deposited on a photocurable protective layer.

[0011] According to one embodiment of the present invention, the polarizing film is formed by laser etching of nanogrooves, and a sandblasting layer is disposed on the outside of the nanogrooves.

[0012] According to one embodiment of the present invention, the above-mentioned sandblasting layer includes a first fluorine-containing silicon ion membrane layer, a second intermediate dielectric layer, and a third crystal powder layer.

[0013] According to one embodiment of the present invention, the intermediate medium layer is configured as a silane coupling agent layer.

[0014] According to one embodiment of the present invention, the particle size of the third crystal powder layer is 20-30 nm.

[0015] A manufacturing process for a polarizing resin lens includes:

[0016] Step a. Provide a polarizing film and etch nanogrooves on its surface using a laser;

[0017] Step b. A fluorine-silicon ion exchange film layer, an intermediate dielectric layer, and a crystal powder layer are sequentially sprayed onto the surface of the polarizing film to form a sandblasted layer with a frosted texture.

[0018] Step c. Place the polarizing film in the middle layer of the rubber ring, then fix the glass mold on both sides, fill the rubber ring with resin using a glue gun, and send it to the oven to cure and form the front resin substrate and the back resin substrate to obtain the polarizing lens.

[0019] Step d. After cleaning the polarizing lens, immerse it in a hardening solution to coat it with a hardening layer;

[0020] Step e. After cleaning, place the lens in a spin coater to spin coat a UV-curable protective layer. After spin coating, place it under a UV lamp for UV curing. After UV curing, perform ultrasonic cleaning and drying on the polarizing lens.

[0021] Step f. After drying, the polarizing lens is sent to a coating machine to coat an anti-reflective layer;

[0022] Step g. After the coating is completed, the lens can be inspected.

[0023] According to one embodiment of the present invention, the thickness of the photocurable protective layer is 6 μm.

[0024] According to one embodiment of the present invention, the thickness of the antireflection layer is 20-130 μm.

[0025] Compared with the prior art, the present invention can achieve the following technical effects:

[0026] By setting a sandblasting layer on the surface of the polarizing film, the adhesion between the front and back resin substrates after curing is enhanced, avoiding the trouble of easy peeling of the polarizing film and enhancing its durability.

[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description

[0032] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a polarizing resin lens according to an embodiment of the present invention.

[0035] In one embodiment of the present invention, the polarizing film 10 is a film made of polarizing material with a smooth surface. A frosted sandblasting layer 20 is formed on its surface to enhance its anti-peel resistance after bonding with resin. A front resin substrate 30 and a rear resin substrate 40 are formed on the front and rear sides of the polarizing film 10, and are combined to form a polarizing lens. A hardening layer 50 is dip-coated onto the surface of the polarizing lens to increase the lens hardness. A UV-cured protective layer 60 is cured by ultraviolet light to protect the hardening layer 50 and improve the adhesion of the antireflective layer 70, thus enhancing protection. The antireflective layer 70 improves the lens's anti-reflective properties.

[0036] The polarizing film 10 of the present invention is made by laser etching nanogrooves, and a sandblasting layer 20 is provided on the outside of the nanogrooves to facilitate the adhesion of the sandblasting layer and enhance the adhesion.

[0037] Preferably, the sandblasting layer 20 includes a first fluorinated silicon ion membrane layer, a second intermediate dielectric layer, and a third crystal powder layer. The first fluorinated silicon ion membrane layer is a fluorine-containing silica sol, which serves as a preliminary surface hardening agent. The second intermediate dielectric layer helps the third crystal powder layer adhere, enhancing the frosted texture and improving adhesion to the cured resin.

[0038] Furthermore, the intermediate medium layer is set as a silane coupling agent layer, which has a better adhesion effect.

[0039] In addition, the third crystal powder layer has a particle size of 20-30nm, which does not affect light transmittance.

[0040] This invention also discloses a manufacturing process for polarizing resin lenses, comprising:

[0041] Step a. Provide a polarizing film and etch nanogrooves on its surface using a laser;

[0042] Step b. A fluorine-silicon ion exchange film layer, an intermediate dielectric layer, and a crystal powder layer are sequentially sprayed onto the surface of the polarizing film to form a sandblasted layer with a frosted texture.

[0043] Step c. Place the polarizing film in the middle layer of the rubber ring, then fix the glass mold on both sides, fill the rubber ring with resin using a glue gun, and send it to the oven to cure and form the front resin substrate and the back resin substrate to obtain the polarizing lens.

[0044] Step d. After cleaning the polarizing lens, immerse it in a hardening solution to coat it with a hardening layer;

[0045] Step e. After cleaning, place the lens in a spin coater to spin coat a UV-curable protective layer. After spin coating, place it under a UV lamp for UV curing. After UV curing, perform ultrasonic cleaning and drying on the polarizing lens.

[0046] Step f. After drying, the polarizing lens is sent to a coating machine to coat an anti-reflective layer;

[0047] Step g. After the coating is completed, the lens can be inspected.

[0048] Preferably, the photocurable protective layer 60 has a thickness of 6 μm to protect the surface film of the lens. The antireflective layer 70 has a thickness of 20-130 μm to improve the antireflective effect of the lens.

[0049] In summary, this invention enhances the adhesion between the front and back resin substrates after curing by setting a sandblasting layer on the surface of the polarizing film, avoiding the trouble of easy peeling of the polarizing film and enhancing its durability.
