Abstract
The utility model discloses a kind of high light transmittance optics PU protective membrane; comprise PET substrate layer; one side of described PET substrate layer is coated with primary coat glue-line; the opposite side of described PET substrate layer is coated with static inhibitor layer; described primary coat glue-line surface is provided with adhesive coating, and PET release film is posted on described adhesive coating surface.The utility model adopts said structure, has the following advantages: 1, have good venting quality (autohension), be difficult for producing bubble during laminating; 2, laminating, afterwards because a variety of causes need to tear off, can not leave cull in screen surface; 3, photopermeability is good, and after pasting over-protective film, the color of screen is still kept intact, and reductibility is good, and image can distortion; 4, the bonding strength of protective membrane is high, durable in use, not because hot and humid impact is used; 5, through anti-electrostatic, process, can avoid the static producing to work the mischief.
Description
Technical field
The utility model relates to a kind of high light transmittance optics PU protective membrane.
Background technology
At present, conventionally on the screens such as mobile phone, palm PC, game machine, all adopt PE (polyethylene) pad pasting as protective membrane, this film venting quality (autohension) is poor, easily produces bubble when pasting, and affects attractive in appearance and vision; In addition, PE film transmittance is poor, easily produces aberration, affects color fidelity.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of high light transmittance optics PU protective membrane, is difficult for producing bubble, photopermeability is good, color reducibility is true to nature, antistatic effect is good object when reaching laminating.
For solving the problems of the technologies described above; the technical solution of the utility model is: a kind of high light transmittance optics PU protective membrane; comprise PET substrate layer; one side of described PET substrate layer is coated with primary coat glue-line; the opposite side of described PET substrate layer is coated with static inhibitor layer; described primary coat glue-line surface is provided with adhesive coating, and PET release film is posted on described adhesive coating surface.
Described adhesive coating is PU pressure-sensitive adhesive.
The utility model adopts said structure, has the following advantages: 1, have good venting quality (autohension), be difficult for producing bubble during laminating; 2, laminating, afterwards because a variety of causes need to tear off, can not leave cull in screen surface; 3, photopermeability is good, and after pasting over-protective film, the color of screen is still kept intact, and reductibility is good, and image can distortion; 4, the bonding strength of protective membrane is high, durable in use, not because hot and humid impact is used; 5, through anti-electrostatic, process, can avoid the static producing to work the mischief.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is lamination layer structure schematic diagram of the present utility model;
In Fig. 1,1, PET substrate layer; 2, primary coat glue-line; 3, static inhibitor layer; 4, adhesive coating; 5, PET release film.
Embodiment
A kind of high light transmittance optics PU protective membrane as shown in Figure 1; comprise PET substrate layer 1, a side of PET substrate layer 1 is coated with primary coat glue-line 2, and primary coat glue-line 2 makes between adhesive layer and PET base material more firm in conjunction with obtaining; the bonding strength that can guarantee laminating, makes protective membrane durable in use.The opposite side of PET (polyethylene terephthalate) substrate layer 1 is coated with static inhibitor layer 3, and primary coat glue-line 2 surfaces are provided with adhesive coating 4, and PET release film 5 is posted on adhesive coating 4 surfaces.Adhesive coating 4 is PU pressure-sensitive adhesive.
The utility model is usingd PET ultrathin membrane replacement PE film as base material, and adopts PU (urethane) glue to be coated with, and the high permeability optical protection layer of making has good, the easy laminating of venting quality (autohension), is difficult for producing bubble; Photopermeability is good, color reducibility is true to nature, can not produce misalignment; Good weatherability, can resistance to certain high temperature and humidity and there is certain bonding strength; Antistatic effect is good, is difficult for making electrostatic damage electrical equipment, hurts people.
Concrete operations are that first the one side at ultra-thin PET film substrate is coated with primary coat glue, then on primary coat glue, is coated with PU pressure-sensitive adhesive and pastes again PET release film; Another side coating static inhibitor layer at ultra-thin PET film substrate; electric equipment products all can have generation of static electricity; static not only can damage electric equipment products used; but also can hurt user, on protective membrane, carry out the health that Electrostatic Treatment can effectively be protected electric equipment products and use operator.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
