Polaroid is wanted to have water-mist-proof function (AF).At present, polaroid produce be difficulty with increasing antifog
Additional function, mainly increases antifogging coating on polaroid, and antifogging coating is easily affected by extraneous factor
Produce and peel off, so that anti-fog effect reduces, even lose anti-fog effect.
Summary of the invention
The one that the purpose of this utility model is contemplated to solve the deficiency of prior art and provides is not only
Simple in construction, the effective for a long time antifogging type polaroid of anti-fog effect.
This utility model is that the following technical solution of employing is attained in that a kind of antifogging type is inclined
Mating plate, it is characterised in that it includes the macromolecular material antifog film layer of layer of polarizer and upper setting thereof,
The antifog film surface of macromolecular material is fitted with protecting film.
Further illustrating as such scheme, described macromolecular material antifog film layer and layer of polarizer it
Between be provided with adhering agent layer, macromolecular material antifog film layer is fitted in layer of polarizer table by sticker
Face, makes macromolecular material antifog film layer be combined with layer of polarizer so that it is the optical effect of existing polarisation,
There is again long-acting lasting anti-fog effect.
Further, described macromolecular material antifog film layer is antifog macromolecular material DAC (two acetic acid
Cellulose) layer, thickness is 50-200um.
Further, described adhering agent layer uses PVA (polyvinyl alcohol) type sticker.
Described layer of polarizer at thickness direction successively by TAC (Triafol T) film layer, PVA
(polyvinyl alcohol) film layer, the 2nd TAC (Triafol T) film layer, pressure-sensitive adhesive layer and stripping film
Layer is composited.
Preferably, (three acetic acid are fine for described TAC (Triafol T) film layer and the 2nd TAC
Dimension element) thickness of film layer is respectively 50-200um, and the thickness of pressure-sensitive adhesive layer is 10-40um.
This utility model uses above-mentioned technical solution can reach to provide the benefit that:
This utility model uses macromolecular material antifog film layer to fit with polaroid, and at macromolecular material
Antifog film layer surface recombination protecting film layer so that it is the optical property of existing polaroid, has again water-mist-proof merit
Can, its macromolecular material antifog film layer is to change the hydrophilicity of material own through saponification, waterproof
Mist performance is effective for a long time, will not be affected generation peeling by extraneous factor and cause anti-fog effect to reduce, very
To losing the problem of anti-fog effect, product meets environmental requirement.

Detailed description of the invention
Below in conjunction with specific embodiment, the technical program is explained in detail.
In description of the present utility model, term " first ", " second " are only used for describing purpose, and
It is not intended that indicate or imply relative importance or the implicit quantity indicating indicated technical characteristic.
As it is shown in figure 1, this utility model is a kind of antifogging type polaroid, it include layer of polarizer and
The macromolecular material antifog film layer of upper setting, the antifog film surface of macromolecular material is fitted with protecting film.
Wherein, it is provided with adhering agent layer, macromolecular material between macromolecular material antifog film layer and layer of polarizer
Antifog film layer is fitted in layer of polarizer surface by sticker, makes macromolecular material antifog film layer and polarisation
Lamella is combined so that it is the optical effect of existing polarisation, has again long-acting lasting anti-fog effect.
Whole antifogging type polaroid structure, from thickness direction successively by protecting film layer 1, macromolecular material
Antifog film layer 2, adhering agent layer the 3, the oneth TAC (Triafol T) film layer 4, PVA (poly-second
Enol) film layer the 5, the 2nd TAC (Triafol T) film layer 6, pressure-sensitive adhesive layer 7 and stripping film
Layer 8 is composited.
Wherein, the effect of protecting film layer 1 is: prevent macromolecular material antifog film layer when actually used
Surface is contaminated, destruction, generally uses PE (polyethylene) film, PET (polyester) film.Its thickness
Suitably can set according to purposes, thickness is generally 50-200um.
Described macromolecular material antifog film layer is antifog macromolecular material DAC (cellulose diacetate) layer,
DAC (cellulose diacetate) material used, removes DAC (diacetate fiber through saponification
Element) in acetyl group (-CO-CH3), generate hydrophilic hydroxyl (-OH), change the hydrophilic of material
Performance so that it is there is good anti-fog performance.Thickness is 50-200um.
Any suitable water-soluble sticky agent is used as adhering agent layer 3, and PVA (poly-second is preferably used
Enol) type sticker, because it can preferably ensure macromolecular material antifog film layer 2 and first
The laminating effect of TAC (Triafol T) film layer 4.
PVA (polyvinyl alcohol) film layer 5, it mainly produces polarisation effect.Production process: PVA is (poly-
Vinyl alcohol) film 5 after-drawing that carries out dyeing in iodine solution makes it have polarization effect, and stretching is dried
PVA (polyvinyl alcohol) film can be thinning and crisp, so both sides laminating the oneth TAC (Triafol T)
Film 4 and the 2nd TAC (Triafol T) film 6.
Oneth TAC (Triafol T) film layer 4 and the 2nd TAC (Triafol T) film layer 6,
Primarily serving protection PVA (polyvinyl alcohol) film 5 to act on, its thickness suitably can set according to purposes,
Thickness is generally 50-200um.
Any suitable pressure sensitive adhesive can be preferably used polyacrylic adhesion as pressure-sensitive adhesive layer 7
Agent, because it can provide excellent weather resistance, its thickness suitably can set according to purposes, thickness
Generally 10-40um.
Stripping film layer 8 is combined with each other by pressure-sensitive adhesive layer and the 2nd TAC (Triafol T) film.
The technical program compared with prior art, uses macromolecular material antifog film layer to paste with polaroid
Close, and at macromolecular material antifog film layer surface recombination protecting film layer so that it is the optics of existing polaroid
Performance, its macromolecular material antifog film layer is to change the hydrophilic of material own through saponification, waterproof
Mist performance is effective for a long time, will not be affected generation peeling by extraneous factor and cause anti-fog effect to reduce, very
To losing the problem of anti-fog effect, product meets environmental requirement.
Above-described is only preferred implementation of the present utility model, it is noted that for this area
Those of ordinary skill for, without departing from this utility model create design on the premise of, it is also possible to do
Going out some deformation and improvement, these broadly fall into protection domain of the present utility model.
