Abstract
The invention discloses a blue-light-resistant optical adhesive tape applied to a display screen. The blue-light-resistant optical adhesive tape applied to the display screen comprises a transparent base material layer, wherein the upper surface and lower surface of the transparent base material layer are respectively coated with an anti-scratching coating layer and a first optical adhesive layer; the surface, opposite to the transparent base material layer, of the first optical adhesive layer is coated with a blue-light-resistant optical adhesive layer; a second optical adhesive layer is arranged between the blue-light-resistant optical adhesive layer and a release material layer; the blue-light-resistant adhesive layer comprises the following components: 100 parts of an acrylate adhesive, 0.075-0.1 part of an isocyanate curing agent, 10-20 parts of butanone, 2-5 parts of nano CeO2:Er fluorescent powder, 0.2-0.5 part of hexamethylphosphoramide, 1-2 parts of benzoyl peroxide and 0.2-0.5 part of silicone oil. The blue-light-resistant optical adhesive tape applied to the display screen has a blue-light-resistant effect and has a function of absorbing and converting bluish violet high-energy short wave; the filtration rate of blue light in a 360nm-500nm waveband reaches over 90%; the eye health can be better protected; the blue-light-resistant optical adhesive tape takes a good adhesive effect on inorganic glass and organic plastic sheets.
Description
Technical field
The present invention relates to a kind of anti-blue light optical adhesive tape for display screen, particularly a kind of OCA optical adhesive tape can for touch-screen with better adhesive property.
Background technology
In recent years, the development of touch-screen is very rapid, and along with growing with each passing day to multimedia information inquiry, people get more and more to the application of touch-screen.OCA optical adhesive tape due to possess water white transparency, transmitance more than 90%, consolidation strength is good, it is little to have cure shrinkage, do not produce the advantages such as xanthochromia, especially to ito glass and the advantage such as optical element is corrosion-free, so rely on its excellent process based prediction model, be widely used in touch-screen industry most.
Simultaneously along with the fast development of electronics technology, the requisite that the electronic product such as portable computer, TV has become people to live, people need the expensive time in the face of these electronic products every day, but include the very large blue light of human injury in the light that sends of the LED of these electronic products.Blue light refers to that wavelength is the high-energy light of 380nm ~ 480nm, it can penetrate lens and arrive retina, the epithelial cell of retinochrome is become feeble and die, photaesthesia cell is caused to lack nutrient, thus cause irreversible vision impairment, and blue light scattering probability when running into the fine particle in air is higher, easily produces dazzle, in addition blue light also can stimulate brain, suppress melatonin secretion and improve corticoid generation thus destroy hormone secretion balance directly affect sleep quality.
Therefore, develop a kind of anti-blue light optical adhesive tape, use it in electronic product, under the prerequisite with preferred optical performance, can also absorb blue light, this has very great meaning by the health of protection human body.
Summary of the invention
The invention provides a kind of anti-blue light optical adhesive tape for display screen, this anti-blue light optical adhesive tape had both had the effect of anti-blue light, royal purple high energy shortwave is had to the function of sorption enhanced, 360nm-500nm blue wave band filterability reaches more than 90%, better protects eye health; Also to unorganic glass and organic plastics sheet, there is better adhesive property.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-blue light optical adhesive tape for display screen, comprise a transparent substrate layer, the upper and lower surface of this transparent substrate layer is coated with anti-scratch coating, the first optical cement adhesion coating respectively, described first optical cement adhesion coating and the opposing surface-coated of transparent substrate layer have anti-blue light adhesive layer, are provided with the second optical cement adhesion coating between described anti-blue light adhesive layer and separated type material layer; Described anti-blue light adhesive layer is composed of the following components:
