Description
Technical field
The present invention relates to liquid panel technique field, especially, relate to a kind of light guide plate protective film.
Background technology
Light guide plate is the product of a kind of high transparency high cleanliness, and it is the highest to the requirement standard of production environment and surface quality,
Rubbed in processing, carrying and transportation in order to avoid light guide plate or caused its surface tear or viscous because of misoperation
Attached dust, the problem of greasy dirt, need to attach on the surface of light guide plate layer protecting film, transport in end, store, process and assemble
After processing, then throw off this film.At present, major part protecting film on market (by poly-to benzene as a example by formic acid two fat protecting film) is deposited
In following defect:
1, the viscosity of protecting film mainly determines according to the thickness of glue, and it is high that viscosity higher position represents thickness, when being warm
When glue-line can flatulence of heat type, time cold can shrinkage, the when of being attached to protected object body can as perspire the same (the excessive glue of industry abbreviation),
So the viscosity of protecting film can not be the highest, not so can feel to be difficult to protecting film of tearing using.And in South China north temperature
Degree difference is big, and temperature in four seasons is clearly demarcated, and the temperature contrast using protecting film is the biggest, and the viscosity of protecting film can be along with in not same district
Territory Various Seasonal and change, to this, user to this problem be very much headache.
2, general protecting film is provided with tear line, carries out tearing along tear line or often occurs broken during cutting etc.
Damage, tear the situations such as dynamics is little.
3, can rise along with the rising of temperature due to protecting film viscosity.When cutting, saw blade runs up, in temperature
Rise, be pasted together with film so often produce film when cutting, cause the problems such as inconvenient operation.
4, existing protecting film the most easily produces cull, the reason of cull occurs mainly: 1. glue is aging；②
Temperature tolerance is poor, bonding beyond use under temperature conditions, can cause cull；3. close with affixed object character, cause between molecule
Migrate cull；4. exceeding certain hot strength and peel strength, every kind of gluing product all has its limit, meets and be the most easily stained with
, high surface energy, it is more likely that cull.The appearance of cull so that whole protecting film is the most easy to attach, its temperature tolerance is the most poor.
Therefore, it is necessary to existing light guide plate protective film is developed further, to avoid drawbacks described above.
Summary of the invention
Tack stability is there is poor, cracky or tear when tear or cutting for the above-mentioned existing light guide plate protective film of solution
Dynamics is little, easily produces the technical problem of cull, and the present invention provides a kind of tack stability good, has good two-way linear easy
Tearing property, without the light guide plate protective film of cull.
The light guide plate protective film that the present invention provides includes base material top layer, elastomer layer and is located in described base material top layer and institute
Stating the sandwich layer between elastomer layer, the percentage by weight of described base material top layer, described elastomer layer and described sandwich layer is followed successively by
30%-54%, 6%-10%, 40%-60%, wherein, described base material top layer includes following component by weight percentage:
The separation auxiliary agent of the polyethylene of 20%-30%, the polypropylene of 60%-70%, the cyclic olefine copolymer of 2%-9% and 2%-9%.
In a kind of preferred embodiment of the light guide plate protective film of present invention offer, described separation auxiliary agent is and described poly-second
The improved polyalkene that alkene, described polypropylene and described cyclic olefine copolymer are incompatible.
In a kind of preferred embodiment of the light guide plate protective film of present invention offer, described elastomer layer is by pressure sensitive adhesive system
Becoming, the density of described elastomer layer is 0.880g/cm3-0.920g/cm3。
In a kind of preferred embodiment of the light guide plate protective film of present invention offer, described sandwich layer includes with percentage by weight
The following component of meter: the polyethylene of 20%-30%, the polypropylene of 60%-70%, the politef of 2%-9% and 2%-9%
Compatibilizing aid.
In a kind of preferred embodiment of the light guide plate protective film of present invention offer, described compatibilizing aid is and described poly-second
The improved polyalkene that alkene, described polypropylene and described politef are compatible.
In a kind of preferred embodiment of the light guide plate protective film of present invention offer, described base material top layer, described elastomer
The thickness of layer and described sandwich layer is followed successively by 30 μm-40 μm, 8 μm-10 μm, 30 μm-40 μm.
Compared to prior art, having the beneficial effects that of the light guide plate protective film that the present invention provides: described light guide plate is protected
There is not large change in film viscosity, will not glue because the high temperature of saw blade produces fusing when cutting with the raise/lower of temperature
Stick together；Meanwhile, the tensile strength of described light guide plate protective film is high, peel strength little and after peeling off without cull, therefore, described
Light guide plate protective film has good easy-to-rupture, so that described light guide plate protective film can reuse；Additionally, at high temperature
Under super-humid conditions, described light guide plate protective film is not crumpled, is shunk, the end of reel, without cull, without hazing.
