Abstract
The utility model relates to a protection film field, concretely relates to double -deck ya keli net protection film of PET, include net layer, pressure sensitive adhesive layer, leave type layer, substrate layer and antistatic backing, substrate layer one side top -coat covers and has the antistatic backing, lateral overlap substrate layer from the type layer, form pressure sensitive adhesive layer from the another side on type layer coating pressure sensitive adhesive, the lining of net layer is in one side of pressure sensitive adhesive layer. The utility model provides the high hardness of protection film, the cost is reduced, and the cross cutting performance is good, improved the adsorptivity of protection film, the adhesive force is light, and simple structure, and the easily production has improved productivity ratio.
Description
Technical field
The utility model relates to protective membrane field, particularly PET Double-layer acrylic grid protection film.
Background technology
At present; protective membrane is often used in and is attached to some and needs to protect on the article on its surface; be widely used in the electronic curtain protection fields such as panel computer, mobile phone, TV, to prevent surface by hard object scratch, modal is the protective membrane being affixed on electronic product screen surface.This type of protective membrane is generally plastic film, according to the difference of purposes, also adopts one deck, two-layer or multilayer film.Along with the development of electron trade; it is in an assembling process in order to reach required structure and assembling effect; material requested layer is only formed by stacking merely by prior art combination as required; the upper and lower surface of face adhesive tape is bonded with release film and protective membrane respectively; during use, it comprises substrate layer, adhesive layer and separated type material layer to protective membrane used in prior art under normal circumstances.In use separated type material layer is torn, by the surface of adhesive layer docile at protected material.But when docile surface, can electrostatic be produced, be unfavorable for the protection of article, and most of protective membrane hardness is not high enough, easily allow article suffer damage.
Utility model content
For solving the problem, the utility model provides that a kind of hardness is high, excellent adsorption and the PET Double-layer acrylic grid protection film of anti-electrostatic.
The technical solution adopted in the utility model is: PET Double-layer acrylic grid protection film; comprise clathrum, pressure-sensitive adhesive layer, release layer and substrate layer; one side of described release layer covering substrates layer; the another side coating pressure sensitive adhesive of described release layer forms pressure-sensitive adhesive layer, and described clathrum is overlayed on the side of pressure-sensitive adhesive layer.
Preferably, described substrate layer is made up of polyethylene terephthalate layer and antistatic backing, and described release layer is coated in the polyethylene terephthalate layer another side relative with antistatic backing.
Preferably, described clathrum is polymethylmethacrylate and thickness is 12 ~ 25 μm.
Preferably, described pressure-sensitive adhesive layer is hot melt pressure sensitive glue.
The beneficial effects of the utility model are, protective membrane adds clathrum, can guide the derivation of bubble, keep the smooth of screen, and can also prevent cross cutting from walking in the process of cross cutting when laminating screen after pad pasting forms bubble; It adds hot melt pressure sensitive glue-line, improves the hardness of protective membrane, reduces cost, and die-cutting performance is good; The bottom of protective membrane adopts antistatic backing, prevents from producing electrostatic between article, both improve the adsorptivity of protective membrane, and clinging power is light; The utility model structure is simple, is easy to produce, and improves productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of PET Double-layer acrylic grid protection film of the present utility model;
In above accompanying drawing: 1, clathrum; 2, pressure-sensitive adhesive layer; 3, release layer; 4, substrate layer; 41, polyethylene terephthalate layer; 42, antistatic backing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, be the structural representation of PET Double-layer acrylic grid protection film of the present utility model.
PET Double-layer acrylic grid protection film, comprise clathrum 1, pressure-sensitive adhesive layer 2, release layer 3 and substrate layer 4, one side of described release layer 3 covering substrates layer 4, the another side coating pressure sensitive adhesive of described release layer 3 forms pressure-sensitive adhesive layer 2, described clathrum 1 is overlayed on the side of pressure-sensitive adhesive layer 2, and protective membrane adds clathrum 1, can guide the derivation of bubble when laminating screen after pad pasting forms bubble, keep the smooth of screen, and can also prevent cross cutting from walking in the process of cross cutting;
In the present embodiment; described substrate layer 4 is made up of polyethylene terephthalate layer 41 and antistatic backing 42; described release layer 3 is coated in polyethylene terephthalate layer 41 another side relative with antistatic backing 42; the bottom of protective membrane adopts antistatic backing 42; prevent from producing electrostatic between article; improve the adsorptivity of protective membrane, and clinging power is light.
In the present embodiment, described clathrum 1 is for polymethylmethacrylate and thickness is 20 μm, and described pressure-sensitive adhesive layer 2 is hot melt pressure sensitive glue; improve the hardness of protective membrane, reduce cost, and die-cutting performance is good; the utility model structure is simple, is easy to produce, and improves productivity.
The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
