Specific embodiment
The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model,
It states.The preferred embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms
It realizes, however it is not limited to embodiment described herein.On the contrary, purpose of providing these embodiments is makes to the utility model
The understanding of disclosure is more thorough and comprehensive.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes
Any and all combinations of one or more related listed items.
Referring to FIG. 1, the adhesive tape structure 100 of the present embodiment includes the protective film 110 stacked gradually, adhesive layer 120, buffering
Layer 130 and release film 140, wherein glue ontology 150 includes buffer layer 130 and adhesive layer 120.Release membrane body covers the glue sheet
The surface of body side, and the two shape is identical.Protection membrane body covers the surface of the glue ontology other side, and the two shape phase
Together.
It should be noted that buffer layer 130 can be foam or composite material, buffer layer 130 is not limited to above two material
Material, the material that can play buffer function all can serve as buffer layer.The material of release film and protective film can for PET or PU or
Acrylic.
It was discovered by researchers that release film 140 and glue ontology 150 are separated when needing to attach adhesive tape, to be attached to display surface
On plate, but cause to be broken in junction since stress concentrations at right angle stress, dispersion are not gone out when tearing off.To avoid
Stress is concentrated, and is found by many experiments, and right angle transition connection is changed, and the stress generated when can be by dyestripping herein disperses
The case where going, carrying out the transfer of power, film layer is avoided to tear generation.
Referring to FIG. 2, release film 200 includes release membrane body 240, and with release membrane body 240 integrally formed the
One tear-away part 250, the first tear-away part 250 have the first side 251, and the first tear-away part 250 and 240 intersection of release membrane body are the
One connecting line, the first side 251 are oppositely arranged with the first connecting line, and the length on the first side 251 is less than first connecting line
Length.
Protective film include protection membrane body and with protection integrally formed second tear-away part of membrane body, the second tear-away part
With the 4th side, the opposite side of the second connecting line of the 4th the second tear-away part Bian Weiyu and the protection membrane body intersection, and
The length on the 4th side is less than the length of second connecting line.
The shape on the first side 251 is not limited to shape shown in Fig. 2, and the first side 251 can be broken line, and waveform is convenient for
Operator is easier to confirm the position of tear-away part.When release film is Chong Die with the tear-away part position of protective film, release film tear-away part
First while with protective film tear-away part the 4th while be set as different shape.
For the ratio of transverse and longitudinal ratio about close to 1: 1, the effect of anti-dyestripping rupture is better.Specifically, with continued reference to FIG. 2,
In the present embodiment, each small ladder uses transverse and longitudinal ratio for 1: 1, and the step-shaped transition that each small ladder transverse and longitudinal ratio is 1: 1 can will
Stress is evenly dispersed to go out, so that stress is uniform everywhere for linkage section, film layer slip gradient when substantially reducing dyestripping.Each small rank
Scalariform is not limited to use transverse and longitudinal ratio for 1: 1.
For convenient for the component that tears off of each film layer is shifted to install, it will usually which the component setting that tears off of some of film layers exists
The non-section of portion position on film layer ontology one side.With reference to Fig. 2, second while and with the first connecting line be that ladder transition is connect when third,
Stair-stepping transverse and longitudinal ratio setting be it is identical, second while with the junction of the first connecting line with when third and the company of the first connecting line
It is identical to connect place's stress, more has and is easy to dyestripping, and reduce film layer slip gradient during dyestripping.
Equally, the second tear-away part have the 5th while and when the 6th, the 5th is opposite while with the 6th, the 5th side and/or
6th side is connect with the second connecting line ladder transition.
The another embodiment of the utility model, referring to Fig. 3, unlike the present embodiment, the second side 352 of release film and/
Or the third side 353 and the connection type of first connecting line it is different, second at 352 and/or the third 353
Angle with first connecting line is obtuse angle.The setting at obtuse angle can disperse away the stress that original concentrates on right angle, greatly
Film layer slip gradient when reducing dyestripping greatly.
When tear-away part is arranged in protective film, the second tear-away part of protective film have the 5th while and when the 6th, the 5th side and the 6th
Side is opposite, 5 the while and/or with the angle of second connecting line be obtuse angle when the 6th.
The obtuse angle size of above-mentioned release film and protective film may be configured as different.
The another embodiment of the utility model, referring to Fig. 4, unlike the present embodiment, the second side of release film 452 and the
The connection of one connecting line ladder transition, third side 453 are connect with the first connecting line round-corner transition, and ladder-like and round-corner transition connects
Connect can in dyestripping dispersive stress.
When protective film is also provided with tear-away part, the second tear-away part of protective film have the 5th while and when the 6th, the 5th side and
6th side is opposite, and the 5th side is connect with the second connecting line ladder transition, and the 6th side is connect with the second connecting line round-corner transition.
Fillet selects 2mm-4mm, and within this range, the circular arc dispersive stress effect of formation is obvious, the probability of film layer rupture
Reduce.The preferred 2mm of fillet.
The fillet size of release film and protective film is settable different, and the ladder transverse and longitudinal ratio of release film and protective film can be set
It is set to different.
When designing adhesive tape structure, specifically, the thickness of release film and protective film is more than or equal to 0.05mm and is less than or equal to
0.1mm, elongation at break are more than or equal to 140%, under the conditions of the setting, can not only disperse by junction stress well
It goes, the thickness of increase adhesive tape that can not be additional.
The drawing force that release film and protective film are generated in dyestripping is greater than the release film or the protective film and glue ontology
Adhesion, therefore film can be easy to tear, and will not destroy film layer by tensile strength >=180Mpa under the range.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
