Description

A kind of polaroid protected and reflected with multilayer

Technical field

The utility model relates to polaroid fields, more particularly, to a kind of polaroid protected and reflected with multilayer.

Background technique

Polaroid (Polarizer) full name is polarized light piece, can control the polarization direction of particular beam.By American Edwin Herbert Land invention.Main function is can to convert polarised light, permeate for the natural light for not having deflection polarity Brilliant steering to control whether penetrating of light, and then generates the display effect of panel light and shade, special using the torsion of liquid crystal molecule Property, reach control light by degree, however existing polaroid easily snaps off, so as to cause that can not be reflected so that It can not be used cooperatively with display, propose a kind of polaroid protected and reflected with multilayer thus.

Utility model content

The utility model is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.

A kind of polaroid protected and reflected with multilayer, including protective film, the first TAC film, PVA film, the second TAC film, Pressure sensitive adhesive and release film, the protective film bottom surface is pasted with the first TCA film, and the first TCA film is made of three cellulose acetate membrane, The bottom surface of the first TCA film is pasted with PVA film, and the PVA film is made of polyvinyl alcohol, and the bottom surface of the PVA film is pasted with 2nd TCA film, the 2nd TCA film is identical as the thickness of the first TCA film, and the characteristic and work of the 2nd TCA film and the first TCA film With all the same, the bottom surface of the 2nd TCA film is pasted with pressure sensitive adhesive, and the 2nd TCA film is carried out by pressure sensitive adhesive and release film Fitting, and release film is poly- to stupid dioctyl phthalate ethylene glycol rouge.

Preferably, the protective film with a thickness of 58 μm.

Preferably, the first TCA film with a thickness of 80 μm.

Preferably, the PVA film with a thickness of 30 μm.

Preferably, the pressure sensitive adhesive with a thickness of 20 μm.

Preferably, the release film with a thickness of 28 μm.

Compared with prior art, the utility model has the beneficial effects that high light transmission rate, water-tolerant have certain machinery again Intensity progress can be protected, so that polaroid is not easily broken, so that the projection of protection to display is unaffected.

The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description In become obvious, or recognized by the practice of the utility model.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is a kind of structural schematic diagram of polaroid protected and reflected with multilayer.

It is as shown in the figure: 1, protective film, the 2, first TAC film, 3, PVA film, the 4, second TAC film, 5, pressure sensitive adhesive, 6, release film.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, in the utility model embodiment, a kind of polaroid protected and reflected with multilayer, including protection Film 1, the first TAC film 2, PVA film 3, the second TAC film 4, pressure sensitive adhesive 5 and release film 6.

1 bottom surface of protective film is pasted with the first TCA film 2, and protective film 1 with a thickness of 58 μm, the protective film 1 has High intensity, high ductibility, acid and alkali-resistance, can antistatic, and single coating pressure-sensitive adhesive, so that polaroid not will receive external force damage Wound, the first TCA film 2 with a thickness of 80 μm, and the first TCA film 2 is made of three cellulose acetate membrane, the first TCA film 2 There is excellent supportive, the bottom surface of optical homogeneity, high transparency, acid and alkali-resistance, UV resistant, the first TCA film 2 is pasted with PVA film 3, and the first TCA film 2 can guarantee that PVA film 3 does not bounce back, and protects PVA film 3 not influenced by aqueous vapor, ultraviolet radiator, ensure that The weatherability of polaroid, the PVA film 3 are made of polyvinyl alcohol, and PVA film 3 with a thickness of 30 μm, the PVA film 3 have height Intensity, high ductibility, excellent iodine suction-operated, good film forming characteristics, and PVA film 3 is optically active, is the core of polaroid The heart, determines the key indexes such as polarizing properties, transmitance, the tone of polaroid, and the bottom surface of the PVA film 3 is pasted with the 2nd TCA Film 4, the 2nd TCA film 4 is identical as the thickness of the first TCA film 2, and the characteristic and effect of the 2nd TCA film 4 and the first TCA film 2 All the same, the bottom surface of the 2nd TCA film 4 is pasted with pressure sensitive adhesive 5, and pressure sensitive adhesive 5 with a thickness of 20 μm, the pressure sensitive adhesive 5 has There are good adhesiveness, the transparency well and residue glue is less, the pressure sensitive adhesive is to determine that being fitted in for polaroid is glutinous on LCD Property and processing performance, the 2nd TCA film 2 be bonded with release film 6 by pressure sensitive adhesive 5, the thickness of the release film 6 It is 28 μm, and release film 6 is poly- to stupid dioctyl phthalate ethylene glycol rouge, the release film 6 has high intensity, is unlikely to deform, the transparency Good and surface smoothness is high.
