Through the 3D polarizer having polymethyl methacrylate protection layers, a defect of poor comprehensive mechanical property of a conventional 3D polarizer is effectively solved; and the provided 3D polarizer is substantially improved in aspects such as anti-extension intensity, tensile strength, bending deformation ability, and stability in polarizing and compensation values.
Description
Technical field
The utility model relates to a kind of polaroid, and in particular a kind of have a polymethylmethacrylate protective seam 3D polaroid.
Background technology
The protective seam of present general 3D polaroid is the three cellulose acetate membrane layer; not only there is the poor defective of comprehensive mechanical property in existing this three cellulose acetate membrane layer aspect material; and because of the restriction of processing technology and the material aspect of 3D polaroid; the selection thickness of existing three cellulose acetate membrane layer is also very thin; and then the thickness that causes having the 3D polaroid of this kind protective seam generally only is 0.3 millimeter or 0.4 millimeter; so because existing three cellulose acetate membrane layer causes existing 3D polaroid in pulling strengrth in the defective aspect material and the thickness; tensile strength; curved change ability, and the aspects such as stability of polarisation and offset are all not good enough.
Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of polymethylmethacrylate protective seam 3D polaroid that has; solving existing 3D polaroid in pulling strengrth, tensile strength, curved change ability, and the aspects such as stability of polarisation and offset not good enough technical matters all.
The technical solution of the utility model is as follows:
A kind of 3D polaroid with polymethylmethacrylate protective seam, wherein, comprise the first anti-scratch hard conating of fitting from top to bottom, polyvinyl alcohol (PVA) rete, the second protective seam, phasic difference rete, the 3rd protective seam, the second anti-scratch hard conating that the first protective seam, high multiple extend, bonding by UV glue between above each layer; Described the first protective seam, the second protective seam and the 3rd protective seam are the polymethylmethacrylate protective seam.
Described 3D polaroid with polymethylmethacrylate protective seam, wherein, the thickness of described the first protective seam, the second protective seam and the 3rd protective seam is set to the 180-220 micron.
Described 3D polaroid with polymethylmethacrylate protective seam; wherein; the thickness of the described first anti-scratch hard conating and the second anti-scratch hard conating is set to the 5-10 micron, and the thickness that the thickness of the polyvinyl alcohol (PVA) rete that high multiple extends is set to 20-40 micron, phasic difference rete is set to the 40-70 micron.
Described 3D polaroid with polymethylmethacrylate protective seam, wherein, the thickness of described the first protective seam, the second protective seam and the 3rd protective seam is set to 200 microns.
The utility model replaces with the polymethylmethacrylate protective seam by each the Triafol T protective seam with existing 3D polaroid; increase again on this basis the thickness of each protective seam; so that the 3D polaroid with polymethylmethacrylate protective seam that the utility model provides is in pulling strengrth, tensile strength, curved change ability, and the aspects such as stability of polarisation and offset all have great improvement.
