Description
Technical field
The present invention relates to optical technical field, more particularly to a kind of optical diffusion film.
Background technology
Optical diffusion film, typically light pass through the diffusion layer using PET as base material, are worn in medium that can be different with refractive index
Cross so that light can correct light into uniform area light source to reach optics diffusion there is a phenomenon where many refractions, reflection and scattering
Effect.
Optical diffusion film is used for the light for spreading point light source or linear light source, or the angle of adjustment emergent light, to obtain
One and front face brightness it is high face illumination.This optical diffusion film is widely used in the liquid such as equipping in mobile phone, digital camera
In crystal display and liquid crystal TV set etc..
Whether more LED backlight or traditional CCFL backlight are applied now, its light sent is a light
Source or line source, rather than area source.But pass through backlight module diffusion barrier, a uniform face light can be scattered in
Source.When light passes through diffusion layer, showed by optics such as the refraction that constantly occurs in the different medium of two kinds of refractive index, reflections
As so as to obtain the result of optics diffusion.
But existing optical diffusion film, substrate layer is inseparable with diffusion layer, inconvenient when diffusion layer needs to dismantle,
Also, existing optical diffusion film is unable to anti-blue light, and injury of the shortwave blue light to human eye is very big, and existing optical diffusion film resists
Electrostatic efficiency is not good enough yet.
Therefore, in view of the above-mentioned problems, being necessary to propose that one kind is separable, and anti-blue light, light antistatic, diffusion effect is good
Diffusion barrier.
The content of the invention
In view of this, the present invention provides a kind of optical diffusion film, including：
Substrate layer；
Tack coat, the tack coat include pressure-sensitive adhesive coating and release film, and the pressure-sensitive adhesive coating and release film are peelable
Be sequentially arranged on a side surface of the substrate layer；
Light diffusion layer, is arranged on a side surface of the remote substrate layer for the tack coat, the light diffusion layer by
Adhesive, crosslinking agent, antistatic additive, anti-blue light resin and light diffusion particle, which cure, to be formed, and the antistatic additive is nanoscale oxygen
Change indium tin.
As a further improvement on the present invention, the smooth diffusion particle includes organic smooth diffusion particle and inorganic light diffusion grain
Son.
As a further improvement on the present invention, the inorganic smooth diffusion particle is acrylic particle, siloxane particles or two
One or more in silicon oxide particle.
As a further improvement on the present invention, the particle diameter of the inorganic smooth diffusion particle is 1-10 μm.
Compared with prior art, the beneficial effects of the invention are as follows：
Optical diffusion film in the present invention, including substrate layer, tack coat and light diffusion layer, tack coat include pressure-sensitive adhesive coating with
Release film, pressure-sensitive adhesive coating is peelable with release film, light diffusion layer by adhesive, crosslinking agent, antistatic additive, anti-blue light resin and
Light diffusion particle, which cures, to be formed, and the tack coat in optical diffusion film is separated with substrate layer, and optical diffusion film anti-blue light, diffusion effect
It is good.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is attached drawing needed in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in invention, for those of ordinary skill in the art, without creative efforts,
Other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the structure diagram of optical diffusion film in the present invention.
Embodiment
The technical solution in the embodiment of the present invention will be described in detail below, it is clear that described embodiment is only
Only it is part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's all other embodiments obtained on the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Join shown in Fig. 1, the diffusion barrier in the present invention, including：
Substrate layer 1；
Tack coat 2, tack coat 2 include pressure-sensitive adhesive coating 21 and release film 22, and pressure-sensitive adhesive coating 21 and release film 22 are peelable
From be sequentially arranged on a side surface of substrate layer 1；Pressure-sensitive adhesive coating 21 has rippability with release film 22, thus when light expands
Dissipate film need do over again, or because other reasons need to dismantle when, by peel off can easily separation substrate layer, tack coat and expansion
Dissipate layer.
Light diffusion layer 3, on a side surface of the remote substrate layer 1 for being arranged at tack coat 2, light diffusion layer 3 by adhesive, hand over
Connection agent, antistatic additive, anti-blue light resin and light diffusion particle, which cure, to be formed.The light diffusion layer being consequently formed, light diffusion effect is good,
Meanwhile the harm that shortwave blue light stripes are come can be avoided with anti-blue light.
Wherein, the raw material of light diffusion layer 3 is formed, antistatic additive is nanometer grade indium tin oxide, can be effectively antistatic.
Light diffusion particle includes organic smooth diffusion particle and inorganic smooth diffusion particle, and inorganic smooth diffusion particle is preferably sub- gram
One or more in power particle, siloxane particles or silica dioxide granule.
The particle diameter of inorganic smooth diffusion particle is 1-10 μm, and the particle diameter is suitable, it is possible to provide preferable light diffusion effect.
As can be seen from the above technical solutions, optical diffusion film includes substrate layer 1, tack coat 2 and light diffusion layer in the present invention
3, tack coat 2 includes pressure-sensitive adhesive coating 21 and release film 22, and pressure-sensitive adhesive coating 21 and release film 22 are peelable, light diffusion layer 3 by
Adhesive, crosslinking agent, antistatic additive, anti-blue light resin and light diffusion particle, which cure, to be formed, and antistatic additive is nanoscale
Indium tin, thus, the tack coat in the present invention in optical diffusion film are separated with substrate layer, and optical diffusion film anti-blue light, diffusion effect
It is good.
