Abstract

The utility model discloses a TPU protection film, the structure of this protection film is from last to moulding the rete for TPU rete, LDPE layer, TPU coating, optics double - sided adhesive layer, silica gel layer and PET fluorine down in proper order, be equipped with TPU hot -melt adhesive layer between LDPE layer and the TPU rete, all be equipped with the bubble on LDPE layer and the TPU hot -melt adhesive layer, adopt TPU and LDPE's composite construction for this bubble chamber film can bear higher pressure, thereby difficult the damage prolongs its life greatly, effectively improves the luminousness and the definition of protection film, design optics double - sided adhesive layer and TPU coating adopt the PET fluorine to mould the rete in addition, effectively improve the luminousness and the definition of protection film, the silica gel layer has the function of quick exhaust bubble to guarantee the laminating effect of protection film, TPU hot -melt adhesive layer bonding reinforce, the applicable temperature wide range, all be equipped with the bubble on LDPE layer and the TPU hot -melt adhesive layer, can regard as the bubble chamber film to use.

Description

A kind of tpu protecting film

Technical field

This utility model is related to tpu technical field of membrane, specially a kind of tpu protecting film.

Background technology

Protecting film, functionally says and is intended to putting a tunic outside our claimed physical item so as to injury-free Etc, in present society, the existing functional type such as ar T-coating, ag frosted anti-reflective film, mobile phone mirror film, peep-proof film is protected Cuticula.But the anti-impact force of these protecting film is poor, easily burst after electronic product screen receives the shock of certain force.

Tpu (thermoplastic polyurethanes), also known as Polyurethane Thermoplastic Elastomer, are broadly divided into polyester Type and polyether-type, its hardness range is wide, high mechanical strength, and bearing capacity, impact resistance, damping property project, and tolerance to cold is excellent, plus Work performance is good, oil resistant, water-fast, resistance to mycete, and regeneration is good, is a kind of very outstanding environment-friendly materials, and tpu is applied On the protective film for digital product through improvement, there is good market prospect.

Utility model content

For problem above, this utility model provides a kind of tpu protecting film, using the composite construction of tpu and ldpe, makes Obtain this bubble chamber film and can bear higher pressure, thus being difficult damaged, greatly prolonging its service life, effectively improving protecting film Light transmittance and definition, can be with the problem in effectively solving background technology.

For achieving the above object, this utility model provides following technical scheme: a kind of tpu protecting film, the knot of this protecting film Structure is followed successively by tpu film layer, ldpe layer, tpu coating, optical double-sided adhesive tape layer, layer of silica gel and pet fluorine plastic film layer from top to bottom, described It is provided with tpu hot melt adhesive layer between ldpe layer and tpu film layer, described ldpe layer and tpu hot melt adhesive layer are equipped with bubble.

Preferably, the thickness of described tpu film layer is 55-65 micron.

Preferably, the thickness of described ldpe layer is 34-37 micron.

Preferably, the thickness of described tpu coating is 45-46 micron.

Preferably, the thickness of described optical double-sided adhesive tape layer is 34-45 micron.

Preferably, the thickness of described layer of silica gel is 67-78 micron.

Preferably, the thickness of described pet fluorine plastic film layer is 23-34 micron.

Compared with prior art, the beneficial effects of the utility model are: using tpu and ldpe composite construction so that should Bubble chamber film can bear higher pressure, thus being difficult damaged, greatly prolonging its service life, effectively improving the saturating of protecting film Light rate and definition；Design optical double-sided adhesive tape layer and tpu coating, in addition adopt pet fluorine plastic film layer, effectively improve the saturating of protecting film Light rate and definition；Layer of silica gel has the function of Quick air-discharge bubble, to ensure the laminating effect of protecting film；Tpu hot melt adhesive layer glues Relay is strong, and Applicable temperature scope is wide, has good heat-resisting, tolerance to cold and acidproof, alkaline-resisting, corrosion resistance and heat stability, Stationarity is good, resistant slide, and adhesive strength is high, and heat resistance is excellent etc.；It is equipped with bubble on ldpe layer and tpu hot melt adhesive layer, can Use as bubble chamber film.

Brief description

Fig. 1 is this utility model structural representation；

In figure: 1-tpu film layer；2-ldpe layer；3-tpu hot melt adhesive layer；4-tpu coating；5- optical double-sided adhesive tape layer；6- silica gel Layer；7-pet fluorine plastic film layer.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Embodiment:

Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of tpu protecting film is it is characterised in that this protection The structure of film is followed successively by tpu film layer 1, ldpe layer 2, tpu coating 4, optical double-sided adhesive tape layer 5, layer of silica gel 6 and pet fluorine from top to bottom Plastic film layer 7, is provided with tpu hot melt adhesive layer 3, on described ldpe layer 2 and tpu hot melt adhesive layer 3 between described ldpe layer 2 and tpu film layer 1 It is equipped with bubble.

The thickness of described tpu film layer 1 is 55-65 micron；The thickness of described ldpe layer 2 is 34-37 micron；Described tpu applies The thickness of layer 4 is 45-46 micron；The thickness of described optical double-sided adhesive tape layer 5 is 34-45 micron；The thickness of described layer of silica gel 6 is 67-78 micron；The thickness of described pet fluorine plastic film layer 7 is 23-34 micron.
