Preferably, the pressure sensitive adhesive is that adhesive solvent, pearl powder and curing agent mix.
Preferably, the adhesive layer 4 is preferably with a thickness of 1 μm to 80 μm, more preferable 6 μm to 40 μm, most preferably 10 μm
To 20 μm.
Preferably, the adhesive layer include solvent type contact adhesive, it is nonaqueous emulsion type contact adhesive, aqueous pressure-sensitive
Adhesive and hot melt pressure sensitive adhesive are, it is preferable to use the pressure-sensitive adhesive containing esters of acrylic acid.
Preferably, the surface of the protective film is coated with oleophobic layer, and the oleophobic layer prepares the preferred silica of raw material.
Compared with prior art, the beneficial effects of the utility model are as follows:
One, the utility model plays protection and buffer action by the setting of release film, avoids being aoxidized in pressure sensitive adhesive
Aggravate and aging, while also avoiding occurring bubble in pressure sensitive adhesive, influences display effect；By the pressure sensitive adhesive of setting, being convenient for will be whole
A polaroid is attached on liquid crystal display；Compound egative film before the substitution of DBEF film, in the case where not influencing its display, significantly
Improve the brightness of product, and a kind of white gravoply, with black engraved characters is presented, forms people and be easy to receive display pattern；Pass through adhesive layer
Setting, not needing anti-aging agent is added just has excellent weatherability, heat resistance and an inoxidizability, and has good transparent
Property and oil resistivity, can with protective layer realize it is more firm Nian Jie；And protective film plays whole support protective effect, especially
DBEF film is protected, prevents from being hit by the external world and breakage occur and lead to not normal use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1- release film, 2- pressure sensitive adhesive, 3-DBEF film, 4- adhesive layer, 5- protective film, 51- oleophobic layer.
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, the utility model provides a kind of technical solution: a kind of display polaroid of adhered attaching,
Including release film 1, pressure sensitive adhesive 2, DBEF film 3, adhesive layer 4 and protective film 5, the setting of release film 1 is for protecting pressure sensitive adhesive 2 not
It is damaged, avoids pressure sensitive adhesive 2 from occurring bubble when being attached to liquid crystal display, the setting of pressure sensitive adhesive 2 is for being attached to liquid for DBEF film 3
On crystal display screen, the compound egative film of polaroid before DBEF film 3 is used to replace, in the case where not influencing its display, greatly
The brightness of product is improved, and a kind of white gravoply, with black engraved characters is presented, people is formed and is easy to receive display pattern, pressure sensitive adhesive 2 is gluing
Solvent, pearl powder and curing agent mix, and the pressure sensitive adhesive 2 made of adhesive solvent, pearl powder and curing agent has higher
Light transmittance, by the setting of adhesive layer 4, not needing anti-aging agent is added just has excellent weatherability, heat resistance and antioxygen
The property changed, and there is the good transparency and oil resistivity, it can be more firm Nian Jie with the realization of protective layer 4, adhesive layer 4 is excellent
Choosing with a thickness of 1 μm to 80 μm, more preferable 6 μm to 40 μm, most preferably 10 μm to 20 μm can be real by the way that different thickness is arranged
