Embodiment 1

[0082] The manufacturing method of the anti-blue light film includes the following steps:

[0083] (1), the preparation of absorbable anti-blue light strengthening liquid: 40% of the oligomer main resin that provides basic performance: one of acrylic urethane and acrylic polyester;

[0084] Monomeric diluents with 20% performance adjustment: acrylates of one or more of the three types of monofunctional, difunctional and polyfunctional;

[0085] Monofunctional

[0086] THFA Tetrahydrofurfuryl Acrylate

[0087] bifunctional

[0088] HDDA1, 6-Hexanediol Dimethanol Diacrylate 1.6-Hexanediol Dimethanol Diacrylate

[0089] Three types of multifunctional groups

[0090] TMPTA Trimethylol propane triacrylate

[0091] After fully reacting with 8% of the initiator for polymerization and cross-linking reaction, it is then uniformly mixed with 10% of the polymer anti-blue light absorber and 3% of the fluorine surfactant that reduces the surface tension, and finally added 19% solvent...

Embodiment 2

[0109] An anti-blue light lens, characterized in that the anti-blue light film produced by the present invention is used as the main layer and the composite film layer lens ( Figure 10 ).

[0110] The structure of the anti-blue lens is characterized in that: the first film layer is the main layer of the anti-blue light film (TAC is the base material), the second film layer and the third film layer are anti-UV ultraviolet light film layers, and the fourth film layer is the anti-scratch film. The protective layer.

[0111] The first film layer is the main layer of the anti-blue light film (TAC is the base material). Has the following beneficial effects:

[0112] (1), strong scratch resistance. With 0000# steel wool with a total load of 500g applied to the test sample, its pressure direction is consistent with the normal direction of the test surface of the sample, and the reciprocating friction is rubbed 25 times at a frequency of 100 times / min, and the scratch resistance re...

Embodiment 3

[0124] A kind of anti-blue light sticking film, it is characterized in that the composite film layer ( Figure 12 ).

[0125] The structure of the anti-blue light film is characterized in that: the first film layer is an anti-blue light film layer (PET base material) as the main film layer, one side of which is coated with silica gel, and the other side is coated with absorbable anti-blue light strengthening liquid; A. The film layer B is a protective film that protects the two sides of the anti-blue light PET film layer of the main body.

[0126] The above-mentioned film layer one is the main body layer of the anti-blue light film (PET base material), which has the following beneficial effects:

[0127] (1), strong scratch resistance. With 0000# steel wool with a total load of 500g applied to the test sample, its pressure direction is consistent with the normal direction of the test surface of the sample, and the reciprocating friction is rubbed 25 times at a frequency of 1...

Abstract

The invention discloses an anti-blue light film and a manufacturing method thereof, and particularly relates to an anti-blue light strengthening liquid, burdening of the anti-blue light strengthening liquid, a proportion of the anti-blue light strengthening liquid, a manufacturing method of the anti-blue light film and a product. The manufacturing method of the anti-blue light film comprises the following steps: preparing adsorbing type anti-blue light strengthening liquid; selecting a main base material; uniformly coating a layer of the prepared adsorbing type anti-blue light strengthening liquid on one surface of the main base material; preparing the anti-blue light film by thermal-energy curing and light-energy curing. The anti-blue light film manufactured by adopting the manufacturing method disclosed by the invention has the characteristics of being strong in scraping resistance and high in transmittance and micro-color bias, effectively protecting in a targeted manner, and being more free, convenient and simpler in product mixing.

Description

technical field [0001] The invention belongs to the field of optical materials, and more particularly, relates to an anti-blue light film and a manufacturing method. Background technique [0002] The World Health Organization WHO Eye Care Association announced that from 2006 to 2008, the annual [0003] More than 30,000 people went blind. According to the data from the Ophthalmology Branch of the Chinese Medical Association, among the 420 million netizens in China, 63.5% of them suffer from different degrees of eye diseases such as decreased vision, cataracts, and blindness due to blue light and radiation. [0004] Existing studies have shown that high-intensity blue light can easily cause damage to the eyes. Blue light can accelerate the oxidation of cells in the macular region of the retina, and irradiation can even damage visual cells. Long-term exposure to blue light in the macula increases the risk of developing macular degeneration in the eye in old age, and may even...
