Example Embodiment

[0026] Example 1:

[0027] The polarized 3D film is composed of a PVA polarizing film in the inner layer, a retardation film in the middle and a triacetate cellulose film (TAC) in the outer layer. It is coated on both sides of the retardation film with acrylic thermal adhesive, and then used A roll press is used to bond the PVA polarizing film and the TAC film on both sides of the retardation film to form a polarized 3D composite film. The polarized 3D composite film is stretched straight on all four sides, immersed in the adhesive solution-polyvinyl alcohol resin containing acetyl ethyl and hydroxymethyl melamine aqueous solution, surface chemical treatment is carried out at room temperature, and then placed at 50-60 ℃ After drying, chemically reactive groups can be obtained on both sides of the polarized 3D film.

[0032] Example 2:

[0033] The polarized 3D film consists of a PVA polarized film in the inner layer, a retardation film in the middle and a PVA film in the outer film. The two sides of the retardation film are coated with an adhesive, dried at 40-60°C, and then rolled The machine glues PVA polarizing film and TAC film on both sides of the retardation film to form a polarized 3D composite film. Here, the polarized 3D composite film does not require additional chemical treatment.

[0034] Fix the polarized 3D film on the fixed frame of the film stretching machine, put it into the fixed tank of a constant temperature wet furnace, control the temperature at 50℃, and the humidity at 65%. After about 10 minutes, take it out and put it in the aluminum film, and put it in a dust-free drying oven , Control the temperature to 80℃ and the humidity to 35%, take it out after 10 minutes.

[0037] Example 3:

[0038] The polarized 3D film consists of a PVA polarized film in the inner layer, a retardation film in the middle and a cellulose acetate propionate film (TAC) in the outer film, which are coated on both sides of the retardation film with acrylic thermosensitive adhesive, and then a roll press is used. Lay the PVA polarized film and TAC film on both sides of the retardation film to form a polarized 3D composite film; stretch the four sides of the polarized 3D composite film, immerse it in the adhesive solution—polyurethane glue, and perform surface chemical treatment at room temperature , And then place it in the air at 30~50℃ and 60% humidity for curing. Chemically reactive groups can be obtained on both sides of the polarized 3D composite film.

[0039] Others are the same as in Example 1.

Abstract

The invention relates to a polarized light 3D (three dimensional) lens and a production method for the polarized light 3D lens. The production method comprises the steps of producing a resin lens and producing a polarized light 3D film, wherein the resin lens is produced according to the following steps: the polarized light 3D film is put in a plastic ring, and a resin monomer is injected in a glass mould to be cured and released to form the lens. The polarized light 3D lens is characterized in that the polarized light 3D film is a polarized light 3D composite film, the polarized light 3D composite film is formed by compositing a PVA (polyvinyl acetate) polarized light film, a phase difference film and a TAC (triallyl cyanurate) film in sequence, or is formed by compositing the PVA polarized light film, the phase difference film and the PVA film in sequence, or is formed by compositing the PVA polarized light film, the phase difference film, the TAC film and the PVA film in sequence, and all the layers are bonded by taking pressure-sensitive adhesive or UV adhesive as a bonder so as to form the 3D composite film; and when the outer-layer film of the polarized light 3D composite film adopts the TAC film, the polarized light 3D composite film is subjected to chemical treatment, so as to obtain chemical reactive groups at the two sides of the polarized light 3D composite film.

Description

technical field [0001] The present invention relates to a polarizing 3D lens, in particular discloses a polarizing 3D lens and a manufacturing method thereof, which realizes the insertion of a polarizing 3D film into a resin lens by casting, and solves the problem of adhesion between the polarizing film and the resin lens. It really realizes that people with poor eyesight can watch 3D film and television works comfortably and conveniently only by wearing a pair of 3D glasses. The structure is simple and beautiful, and it is easy to use. Background technique [0002] Polarized 3D glasses, as a new darling of the glasses industry. With the development of science and technology, human beings will have higher and higher requirements for visual effects. However, general TV or movies can no longer meet the requirements of consumers. Therefore, TVs, projectors, movies, and computers with 3D visual effects are becoming more and more popular. Loved by consumers. [0003] Polarized ...
