Abstract

The invention discloses a protection film with resistance to blue light. A first blue-light-resistant adhesive layer and a second blue-light-resistant adhesive layer coat the upper surface and the lower surface of a transparent substrate layer respectively; a first release material layer is laminated on the other surface of the first blue-light-resistant adhesive layer; a second release material layer is laminated on the other surface of the second blue-light-resistant adhesive layer; each of the first blue-light-resistant adhesive layer and the second blue-light-resistant adhesive layer is produced by the following components: 100 parts of acrylate adhesive, 0.1 part of isocyanate curing agent, 12 parts of butanone, 2.45 parts of nano CeO2:Er fluorescent powder, 0.35 part of hexamethylphosphoramide, 2 parts of benzoyl peroxide and 0.4 part of silicone oil; the type of the isocyanate curing agent is Bayer L-75. The protection film with resistance to blue light has the effect of resisting blue light; the problems that the thickness is not easy to control and bubbles are easily generated during curing and shrinking can also be solved.

Description

Intercept blue light protecting film
Technical field
The present invention relates to a kind of protecting film, can be to unorganic glass and organic plastics sheet for touch screen particularly to one There is the obstruct blue light protecting film of preferable adhesive property.
Background technology
In recent years, the development of touch screen is extremely rapid, and along with growing with each passing day multimedia information inquiry, people are to touch The application of screen gets more and more.Intercept blue light protecting film due to possess water white transparency, transmitance more than 90%, cementing strength good Good, to have cure shrinkage little, does not produce the advantages such as xanthochromia, especially to advantages such as ito glass and optical element are corrosion-free, so By the process based prediction model that it is excellent, most widely it is applied to touch screen industry.
Simultaneously along with the fast development of electronics technology, it is required that the electronic product such as portable computer, TV has become that people live Product, people need to expend a great deal of time in the face of these electronic products every day, but what the LED of these electronic products sent Light includes the blue light the biggest to human injury.Blue light refers to the high-energy light that wavelength is 380nm ~ 480nm, and it can be worn Crystalline lens arrives retina thoroughly, makes the epithelial cell of retinal pigment become feeble and die, causes photaesthesia cell to lack nutrient, thus cause Irreversible vision impairment, and during fine particle that blue light is in running into air, scattering probability is higher, easily produces dazzle, this Outer blue light also can stimulate brain, and suppression melatonin secretion also improves the generation of corticoid thus destroys hormone secretion balance Directly affect sleep quality.
Therefore, a kind of optical adhesive tape of exploitation, use it in electronic product, on the premise of there is preferred optical performance, Can also absorb blue light, this will have the most great meaning to the health of protection human body.
Summary of the invention
The present invention provides a kind of and intercepts blue light protecting film, and this intercepts blue light protecting film and has the effect of anti-blue light, also Solving thickness wayward, cure shrinkage easily produces the problem of bubble, thus obtains on display screen preferably should touching With.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of blue light protecting film that intercepts, transparent including one Substrate layer, the upper and lower surface of this transparent substrate layer has been respectively coated with the first anti-blue light adhesive layer, the second anti-blue light adhesive layer, institute State first another surface of anti-blue light adhesive layer and be covered with the first separated type material layer, described second another surface of anti-blue light adhesive layer patch It is covered with the second separated type material layer；Described first anti-blue light adhesive layer, the second anti-blue light adhesive layer are the most composed of the following components:
Acrylic ester adhesive 100 parts,
Isocyanate curing agent 0.08 part,
Butanone 18 parts,
Ceria nanopowder: 4.25 parts of Er fluorescent material,
HMPA 0.25 part,
Benzoyl peroxide 1.2 parts,
Silicone oil 0.5 part；
Described isocyanate curing agent model is Bayer L-75；
The weight average molecular weight range 200 ~ 8,000,000 of described acrylic acid series adhesive, vitrification point is-60 ~-30 DEG C；
Described transparent base layer thickness is 50～100 μm, light transmittance ＞ 98%, mist degree ＜ 1.0%.
The technical scheme improved further in technique scheme is as follows:
1., in such scheme, the thickness of described anti-blue light coating is 0.5～3 μm.
2., in such scheme, described transparent substrate layer is film layer or layer of polypropylene foil or laminated polyester film.
Owing to technique scheme is used, the present invention compared with prior art has following advantages and an effect:
The present invention intercepts blue light protecting film, and it had both had the effect of anti-blue light, has the merit of sorption enhanced to royal purple high energy shortwave Can, 360nm-500nm blue wave band filterability reaches more than 90%, preferably protects eye health；Also to unorganic glass and organic Plastic sheet has preferable adhesive property；Secondly, specific formula combination, solve liquid optical cement due to ceria nanopowder: Er is glimmering The addition of light powder causes thickness wayward, and cure shrinkage easily produces the problem of bubble, thus effectively prevent the generation of bubble, Preferably applied on display screen touching.
