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 thickening 3D polaroid, and is poor to solve existing 3D polaroid comprehensive mechanical property, 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 thickening 3D polaroid, 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 or the 3rd protective seam are the Triafol T protective seam, and thickness is set to the 170-270 micron.
Described thickening 3D polaroid, 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 thickening 3D polaroid, wherein, the thickness of described the first protective seam, the second protective seam or the 3rd protective seam is set to 200 microns.
The utility model is by the thickness of each Triafol T protective seam of the existing 3D polaroid of increase; so that the thickening 3D polaroid 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.
