Abstract
This case relates to a kind of TPU explosive-proof protector film, and it is provided with PET protective layer, TPU coating, OCA glue-line, optics pet layer, layer of silica gel and PET fluorine plastic film layer from top to bottom successively.TPU explosive-proof protector film involved by this case adopts super transmissive optical level PET, effectively improves light transmittance and the definition of diaphragm; And adopt TPU coating+OCA glue-line integrated mode, substantially increase the ability of diaphragm buffering collision of closed, prevent screen from bursting; Used silica gel layer has the ability to screen glass automatic absorbing, is applicable to the screen of certain radian, and the function keeping Quick air-discharge to steep, to ensure the laminating effect of diaphragm.
Description
Technical field
The utility model relates to a kind of macromolecule membrane, particularly relates to a kind of TPU explosive-proof protector film.
Background technology
Diaphragm, functionally says it is will put a skim to outside our claimed physical item, make it injury-free and so on, present society has the functional form diaphragms such as AR T-coating, AG frosted anti-reflective film, mobile phone mirror film, peep-proof film.But the anti-impact force of these diaphragms is poor, the shock receiving certain force at electronic product screen easily bursts afterwards, is therefore necessary that a both impact resistances of exploitation are explosion-proof, has again the diaphragm of high-transmittance, fine definition.
TPU (Thermoplastic polyurethanes); have another name called TPUE, be mainly divided into polyester-type and polyether-type, its hardness range is wide; mechanical strength is high; bearing capacity, impact resistance, damping property are outstanding, and cold resistance is excellent, good processability; oil resistant, water-fast, resistance to mould; regeneration is good, is a kind of very outstanding environment-friendly materials, and TPU is applied to through improvement protective film for digital product on there are good market prospects.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model be to provide a kind of be used for protecting flat-panel screens panel surface (glass, acrylic or PC material), CRT, touch control type screen, mobile phone, digital camera PDA panel the bright high-resolution diaphragm of the height with shock resistance explosion-proof performance.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of TPU explosive-proof protector film, is provided with PET protective layer, TPU coating, OCA glue-line, optics pet layer, layer of silica gel and PET fluorine plastic film layer from top to bottom successively.
Preferably, described TPU explosive-proof protector film, the thickness of described PET protective layer is 70 ~ 80 μm.
Preferably, described TPU explosive-proof protector film, the thickness of described TPU coating is 140 ~ 160 μm.
Preferably, described TPU explosive-proof protector film, the thickness of described OCA glue-line is 25 ~ 35 μm.
Preferably, described TPU explosive-proof protector film, the thickness of described optics pet layer is 40 ~ 60 μm.
Preferably, described TPU explosive-proof protector film, the thickness of described layer of silica gel is 25 ~ 35 μm.
Preferably, described TPU explosive-proof protector film, the thickness of described PET fluorine plastic film layer is 40 ~ 60 μm.
The beneficial effects of the utility model are: 1) adopt super transmissive optical level PET, effectively improve light transmittance and the definition of diaphragm; 2) adopt TPU coating+OCA glue-line integrated mode, substantially increase the ability of diaphragm buffering collision of closed, prevent screen from bursting; 3) layer of silica gel has the ability to screen glass automatic absorbing, is applicable to the screen of certain radian, and the function keeping Quick air-discharge to steep, to ensure the laminating effect of diaphragm.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of TPU explosive-proof protector film of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, the structure of this TPU explosive-proof protector film is: be provided with PET protective layer 1, TPU coating 2, OCA glue-line 3, optics pet layer 4, layer of silica gel 5 and PET fluorine plastic film layer 6 from top to bottom successively.
Wherein, the thickness of PET protective layer 1 is preferably 70 ~ 80 μm, and its effect is from damage as pre-protective layer protection TPU coating.If the thickness of PET protective layer 1 is less than 70 μm, then can affect its pre-protective capability, if the thickness of PET protective layer 1 is greater than 80 μm, then production cost improves.
The thickness of TPU coating 2 is preferably 140 ~ 160 μm; if the thickness of TPU coating 2 is less than 140 μm, then will reduce its impact resistance explosion-proof performance, if the thickness of TPU coating 2 is greater than 160 μm; then can increase production cost, and integral light-transmitting degree and the definition of diaphragm can be reduced.
The thickness of OCA glue-line 3 is preferably 25 ~ 35 μm, and OCA glue-line is tack coat, can be used as cushion again, and collaborative TPU coating is to reach the object of buffering percussive force.If the thickness of OCA glue-line 3 is less than 25 μm, then glue-line cohesive force is poor, affects the service life of diaphragm; If the thickness of OCA glue-line 3 is greater than 35 μm, then production cost can be increased, and blocked up glue-line can reduce light transmittance and the definition of diaphragm.
The thickness of optics pet layer 4 is preferably 40 ~ 60 μm, optics PET is super transmissive optical level PET, to improve light transmittance and the definition of diaphragm, if the thickness of optics pet layer 4 is less than 40 μm, then PET thickness is crossed when thin meeting causes it to be coated with on large-scale coating machine and easily phenomenon of rupture is occurred; If the thickness of optics pet layer 4 is greater than 60 μm, then production cost can be improved.
The thickness of layer of silica gel 5 is preferably 25 ~ 35 μm, and layer of silica gel has the ability to screen glass automatic absorbing, is applicable to the screen of certain radian, and has both the function of Quick air-discharge bubble, thus ensure that the laminating effect of diaphragm.If the thickness of layer of silica gel 5 is less than 25 μm, then can affect its automatic absorbing ability and automatic Quick air-discharge bubble ability; If the thickness of layer of silica gel 5 is greater than 35 μm, then can affect light transmittance and the definition of diaphragm entirety.
PET fluorine plastic film layer 6 is a kind of mould release membrances, and its thickness is preferably 40 ~ 60 μm, and its effect mainly protects layer of silica gel before use from pollution, when needs use diaphragm, and the PET fluorine plastic film layer 6 by diaphragm jointing product screen surface of only need tearing.
This product can be used to panel surface (glass, acrylic or PC material), CRT, touch control type screen, mobile phone, the digital camera PDA panel of protecting flat-panel screens, can effective buffering collision of closed, prevent screen from bursting thus affecting attractive in appearance, or prevent from mobile phone from accidentally clashing into causing the fragmentation of face glass to disperse, reduce the covert harm of face glass, ensure user security; Also can maintain the distinctive gloss of tempered glass, texture and raising case hardness.
Performance test data so that following table one is this product:
Table one
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
