Description
Technical field
The utility model belongs to physical optical arts, and in particular to a kind of multilayer light diffusing sheet.
Background technology
Light diffusing sheet be light by the diffusion layer with PMMA/PC/PE etc. for plastic basis material, encounter different with its refractive index
Diffusion particle when, it may occur that multi-direction, multi-angle refraction, reflection and scattering phenomenon obtain optics diffusion effect with this.
Traditional light diffusing sheet mainly uses two ways：First, the bar shaped of individual layer or loop configuration；2nd, the light diffusion of multiple individual layers
Plate is superimposed.Diffusion particle is mainly added in diffusion body, light is allowed to be more evenly distributed, softer.But both modes are all
There are it is certain the defects of：One, light diffusing sheet have certain Property requirements, such as antistatic property, light transmittance, mist degree, so will
Its material and diffusion particle therein is asked to mix a variety of material agent, so cost is larger；Secondly, the light diffusing sheet light transmission of single layer structure
Rate is low, even light effect is poor；Thirdly, light diffusing sheet it is more crisp, so fragile.Moreover, using traditional light diffusing sheet, if necessary
It realizes other physical functions, then needs to add a large amount of functional material, can undoubtedly greatly increase production cost in this way.
Utility model content
In order to solve the above-mentioned technical problem, the utility model proposes a kind of multilayer light diffusing sheet, including：First extexine,
Middle layer, the second extexine.The thickness of traditional individual layer light diffusing sheet is not changing its thickness between 1.0mm~2.5mm
In the case of made into multilayered structure.The material and thickness of wherein the first extexine and the second extexine are identical, and
Middle layer is the diffusion body of light diffusing sheet, that is, typical case's ABA structures.Using the utility model structure, by the first extexine,
The independent entirety of the effect of second extexine comes, and toughness is preferable, protects the second extexine of middle layer.Realize entire light diffusing sheet light
Spreading, uniformly for source, effectively improves the toughness of entire light diffusing sheet.
A kind of multilayer light diffusing sheet, including：First extexine 1, middle layer 2, the second extexine 3, wherein described first
The material of extexine 1 and second layer extexine 3, thickness be it is identical, first extexine 1 and the second extexine 3 it
Between for middle layer 2, the material of the middle layer 2 is different with the first extexine 1 or the second extexine 3 from thickness.
Further, in order to realize the protective effect to middle layer 2 and improve the toughness of whole light diffusing sheet, outside first
The material selection of 1 and second extexine 3 of surface layer has the function of one or more in the material for having anti-UV, antistatic, foaming etc..
Under normal conditions, anti-UV agent is added in masterbatch, can cause light diffusing sheet that there is the effect of anti-UV；It is added in masterbatch anti-quiet
Electric agent can cause light diffusing sheet to have anlistatig effect；Foaming agent is added in masterbatch, can light diffusing sheet be had
The effect of foaming.Further, the anti-UV agent includes benzoic acids, benzophenone, benzotriazole or part and is obstructed
At least one of amine.Further, the antistatic agent includes sulfate derivative, phosphoric acid derivatives, amine, quaternary ammonium
At least one of salt, imidazoles and epoxyethane derivative.Further, the foaming agent include chemical foaming agent,
Physical blowing agent and surfactant, it is preferred that using inorganic chemical foaming agent.
Further, hardness, toughness and the anti-grieshoch of 3 material of the first extexine 1 and the second extexine also have certain
It is required that.
Further, it is generally the case that the first extexine 1, middle layer 2, the overall thickness of the second extexine 3 for 1.0mm~
2.5mm.Preferably, the thickness of the first extexine 1 and the second extexine 3 and the 6%~7% of overall thickness is accounted for.
It may further be preferable that light transmittance, mist degree, sheet resistance and size, thickness, hair to be carried out to light diffusing sheet
The damage testings such as side, scuffing, unfilled corner.
Further, single layer structure may be used in the middle layer, can also use multilayered structure.
Further, the middle layer is polystyrene (PS), makrolon (PC), polyethylene (PE), polypropylene
(PP), in polyvinyl chloride (PVC), polyethylene terephthalate (PET), acryl (PMMA), acrylic acid (MMA) at least
It is a kind of.
Using multilayer light diffusing sheet as described above, the toughness of entire light diffusing sheet is effectively enhanced.Specifically, more crisp
Diffusion layer middle layer the first extexine 1 and the second extexine 3 of certain proportion thickness are respectively arranged about 2, to protect light
Diffuser plate realizes spreading, uniformly for entire light diffusing sheet light source, while the whole toughness for promoting light diffusing sheet.This is simple in structure
Practicality, for the light diffusing sheet of single layer structure, overall flexibility is obviously improved.
