Adhesive tape assembly
As shown in Figures 3 to 10, the embodiment of the present invention provides a kind of Adhesive tape assembly, is used to be bonded at least one base
On bottom 9, and Adhesive tape assembly includes：
Stretchable removal adhesive tape 1, with adhesive surface 11；
Intermediary layer 2 covers the stretchable at least partly adhesive surface 11 for removing adhesive tape 1, and has the first opposite face 21
With the second face 22；Wherein,
First face 21 is used to bond with substrate 9；
Second face 22 is bonded on adhesive surface 11, and has at least partly the second face 22 directly to be contacted with adhesive surface 11；
Second face 22 has the Ra values between 0.1 μm to 7 μm.
That is, as shown in Figure 3, Figure 4, the Adhesive tape assembly of the embodiment of the present invention includes conventional stretchable removal adhesive tape
1, which is equipped with the adhesive surface 11 (having sticking face) for being bonded with substrate 9.
At least part of adhesive surface 11 is covered with intermediary layer 2, intermediary layer 2 towards the side of adhesive surface 11 be the second face 22, the second face
22 have specific roughness, i.e. its Ra value (profile arithmetic mean deviation, arithmetical mean deviation of the
Profile) between 0.1 μm to 7 μm, and at least the second face of part 22 is directly to be contacted with adhesive surface 11；And intermediary layer 2
The other side be the first face 21, first face 21 is for being bonded in substrate 9.
When Adhesive tape assembly is bonded in substrate 9, intermediary layer 2 can between stretchable removal adhesive tape 1 and substrate 9,
As " intermediary " of the two, and the second face 22 with specific roughness can connect with stretchable removal adhesive tape 1 (adhesive surface 11)
It touches.Thus as shown in figure 5, when being stretched to stretchable removal adhesive tape 1, stretchable removal adhesive tape 1 can be detached with intermediary layer 2
And slided on second face 22, i.e., the originally stretchable sliding for removing adhesive tape 1 in substrate 9 becomes on the second face 22
Sliding.The present invention has now surprisingly been found that, if the face (the second face 22) contacted with stretchable removal adhesive tape 1 is with specific coarse
Degree, then its resistance to sliding between stretchable removal adhesive tape 1 is with regard to relatively low.Therefore, the above intermediary layer 2 can reduce stretchable removal glue
Band 1 be stretched remove when (when especially draw angle is larger) suffered by resistance to sliding, to avoid stretchable 1 quilt of removal adhesive tape
It breaks, improves the reliability of Adhesive tape assembly.
Why have face and the stretchable resistance to sliding removed between adhesive tape 1 of specific roughness relatively low, it may be possible to due to
Following reason (restriction set forth below not to action principle of the present invention)：When stretchable removal adhesive tape 1 is stretched, surface
Molecule occurs height-oriented and surface undulation and is largely eliminated, you can stretching 1 surface of removal adhesive tape can become coarse
The very low shiny surface of degree, the contact area if the face being in contact with it is also very smooth between the two is very big at this time, leads to still have one
The stretchable removal adhesive tape 1 of fixed viscosity can be well-bonded with the face, and resistance to sliding increases.If correspondingly, with stretchable removal glue
Face with 1 contact is excessively coarse, then the stretchable adhesive tape 1 that removes is easy to be scratched by the spike of coarse structure in sliding process, from
And causes resistance to sliding to increase and stretchable removal adhesive tape 1 is made to be easily broken off.And when roughness is located at particular range, can make with
Upper both sides influence reaches balance, resistance to sliding is preferably minimized, best avoids stretchable removal adhesive tape 1 from being pulled off.
A kind of specific implementation mode according to the present invention, the second face 22 have the Ra values between 0.15 μm to 6 μm.
That is, second face 22 more preferably has between 0.2 μm to 5 μm preferably with the Ra values between 0.15 μm to 6 μm
Ra values, further preferably with the Ra values between 0.5 μm to 4 μm.
Wherein, any of stretchable removal adhesive tape product, such as 3M wounds can be used in above stretchable removal adhesive tape 1
The stretchable removal adhesive tape of 6701-150 types of new company (U.S., the Minnesota State, Sao Paulo), is not described in detail herein.
Wherein, although in the drawings with it is stretchable remove adhesive tape 1 every side be entirely adhesive surface 11 as an example,
It should be appreciated that if only portion is adhesive surface 11 in the stretchable side for removing adhesive tape 1, and remaining position is without viscous
Property and feasible.For example, the stretchable one end for removing adhesive tape 1 can be without viscosity, using as drawing when being stretched
Hand.
Wherein, any of film layer can be used in above intermediary layer 2, another as long as one side can be bonded in substrate 9
Side has the above specific roughness.Preferably, which can be made of polymer material, such as polyimides, poly-
Ethylene glycol terephthalate, makrolon etc., are not described in detail herein.
And the thickness of intermediary layer 2 generally can be at a few micrometers between hundreds of microns, such as between 5 μm to 800 μm, preferably
Between 10 μm to 500 μm, more preferably between 20 μm to 200 μm, further preferably between 25 μm to 100 μm.
A kind of specific implementation mode according to the present invention, the first face 21 are equipped with pressure sensitive adhesives 219 or double faced adhesive tape.
That is, being the first face 21 of intermediary layer 2 since Adhesive tape assembly has part surface, therefore to realize Adhesive tape assembly
With the bonding of substrate 9, then first face 21 will be bonded in substrate 9；Therefore, it is preferably provided with pressure-sensitive adhesive on the first face 21
Agent 219 or double faced adhesive tape.The pressure sensitive adhesives 219 can be conventional Acrylate pressure sensitive binder, polyurethane pressure sensitive binder,
Polyvinyl chloride pressure sensitive adhesives etc., is not described in detail herein.
Certainly, if the first face 21 does not have binder, but to be carried out in substrate 9 cohesive position setting binder or
Double faced adhesive tape and feasible.
A kind of specific implementation mode according to the present invention, the stretchable both sides for removing adhesive tape 1 all have adhesive surface 11, wherein
Only there are one be bonded with intermediary layer 2 on adhesive surface 11.
That is, as shown in Fig. 3, Fig. 6, stretchable removal adhesive tape 1 can both sides have adhesive surface 11, this is because can draw
It stretches and removes adhesive tape 1 commonly used in the inconvenient occasion that directly adhesive tape is torn from substrate 9, and general adhesive tape is all in this occasion
It is bonded between two substrates 9, therefore the preferably stretchable both sides for removing adhesive tape 1 can be bonded.And due in reality
In the application of border, can generally determine in advance when to remove stretchable removals adhesive tape 1 should (can only in such as Figure 10 to which direction stretching
Stretch upward), and stretchable removal adhesive tape 1 is only in (the first substrate in such as Figure 10 of substrate 9 close to draw direction side
91) it is slided on, as long as therefore stretchable removal adhesive tape 1 is equipped with intermediary layer 2 in the side.
A kind of specific implementation mode according to the present invention, the stretchable at least one end for removing adhesive tape 1 do not have intermediary layer
2。
That is, as shown in Fig. 3, Fig. 7, the stretchable at least one end for removing adhesive tape 1 be arranged more than in
Interlayer 2.This is because when removing stretchable removal adhesive tape 1, stretchable removal adhesive tape 1 first to be made to be detached with intermediary layer 2, to protect
Demonstrate,proving stretchable removal adhesive tape 1 can slide on intermediary layer 2 to reduce resistance to sliding.And if the stretchable end for removing adhesive tape 1
Also there is intermediary layer 2, then the end of the two flushes as shown in Figure 6, therefore is at this moment difficult the two to be separated in end.
A kind of specific implementation mode according to the present invention, on the stretchable length direction for removing adhesive tape 1, the second face 22 with
The size for the part that adhesive surface 11 is in direct contact is at least 5 millimeters.
That is, stretchable remove in the intermediary layer 2 being arranged on adhesive tape 1, the second face directly contacted with adhesive surface 11
22 will be to the youthful and the elderly 5 millimeters (can also have and be equipped with other structures between the second face of part 22 and adhesive surface 11).This is because being drawn
It is practical to only have 9 edge part of substrate and the stretchable resistance to sliding removed between adhesive tape 1 larger when stretching, thus it is at least necessary in the position
Equipped with the intermediary layer 2 (the second face 22) directly contacted with adhesive surface 11.And the it is a discovery of the invention that larger part of the above resistance to sliding
General length is within 5 millimeters, therefore the second face 22 directly contacted with adhesive surface 11 should be 5 millimeters to the youthful and the elderly.Certainly, if directly
22 length of the second face contacted with adhesive surface 11 is longer, to preferably play the role of reducing resistance to sliding and feasible.
A kind of specific implementation mode according to the present invention, on being bonded with the adhesive surface 11 of intermediary layer 2, along stretchable removal
The length direction of adhesive tape 1, intermediary layer 2 only cover a part for the adhesive surface 11；Or, in the adhesive surface 11 for being bonded with intermediary layer 2
On, along the stretchable length direction for removing adhesive tape 1, the adhesive surface 11 is completely covered in intermediary layer 2.
That is, on the adhesive surface 11 with intermediary layer 2, intermediary layer 2 can be as shown in figure 3, only cover the adhesive surface
11 part.This is because as previously mentioned, length is smaller in fact the higher part of resistance to sliding, as long as therefore the part adhesive face
11 are equipped with intermediary layer 2, and such other positions are still that the stretchable adhesive surface 11 for removing adhesive tape 1 is directly viscous with substrate 9
Knot can ensure that the stretchable adhesive property for removing 1 script of adhesive tape is constant as possible.
Alternatively, also can be as shown in fig. 6, if certain adhesive surface 11 carries intermediary layer 2, the bonding be just completely covered in intermediary layer 2
Face 11.Obviously, if intermediary layer 2 is only located at the stretchable portion for removing adhesive tape 1, careful pair must be carried out when attaching
Position, with ensure intermediary layer 2 be located at substrate 9 edge part (otherwise intermediary layer 2 just do not have reduce resistance to sliding effect), grasp
It is difficult to make.And if intermediary layer 2 covers entire adhesive surface 11, operates just simpler.
A kind of specific implementation mode according to the present invention, in the stretchable width direction for removing adhesive tape 1, intermediary layer 2
Size is greater than or equal to the stretchable width for removing adhesive tape 1.
Obviously, from reduce resistance to sliding and it is easy to use from the point of view of, the second face 22 should cover the whole of adhesive surface 11
A width range, i.e., as shown in figure 4, intermediary layer 2 should be with stretchable removal adhesive tape 1 with wide or more wider than its.
Certainly, if the width of intermediary layer 2 is smaller than the stretchable width for removing adhesive tape 1, certain reduction can also be played
The effect of resistance to sliding.Typically, stretchable removal adhesive tape 1 is avoided to be pulled off to reliable, then 2 width of intermediary layer
It at least should be stretchable and remove the 30%, more preferably at least 50% of 1 width of adhesive tape, further preferably at least 80%.Obviously,
When 2 width of intermediary layer is less than stretchable removal 1 width of adhesive tape, it should preferably be set to stretchable removal 1 width direction of adhesive tape
Middle part.
A kind of specific implementation mode according to the present invention, Adhesive tape assembly further include low-viscous layer 3, are located at intermediary layer 2
Between one end and stretchable removal adhesive tape 1；And low-viscous layer 3 and the stretchable adhesion strength and low removed between adhesive tape 1
In adhesion strength between viscous layer 3 and intermediary layer 2, at least one is less than the adhesion strength between intermediary layer 2 and substrate 9.
That is, as shown in fig. 7, can be also equipped between an end of intermediary layer 2 and stretchable removal adhesive tape 1 low
Viscous layer 3 (obviously, in the position equipped with low-viscous layer 3, then the second face 22 is not in direct contact with adhesive surface 11), the low-viscous layer
3 have lower adhesion strength, to ensure its it is stretchable removal adhesive tape 1 between adhesion strength and/or its between intermediary layer 2
Adhesion strength it is lower than the adhesion strength between intermediary layer 2 and substrate 9.As a result, the effect of the low-viscous layer 3 be make intermediary layer 2 with
The stretchable separation stress removed between adhesive tape 1 is less than the cohesive force between intermediary layer 2 and substrate 9, thus during removal, energy
Ensure that necessarily stretchable removal adhesive tape 1 is detached with intermediary layer 2, without will produce intermediary layer 2 with stretchable removal adhesive tape 1 one
Play the case where being removed from substrate 9.
A kind of specific implementation mode according to the present invention, low-viscous layer 3 and the stretchable adhesion strength removed between adhesive tape 1 are big
Adhesion strength between low-viscous layer 3 and intermediary layer 2.
That is, mode more preferably, low-viscous layer 3 and the stretchable adhesion strength removed between adhesive tape 1 are larger,
And the adhesion strength between intermediary layer 2 is smaller.In this way when detaching stretchable removal adhesive tape 1 with intermediary layer 2, low-viscous layer 3
Will necessarily be bonded on stretchable removal adhesive tape 1 and be detached with intermediary layer 2, with it is stretchable remove adhesive tape 1 continue to stretch it is low
Viscous layer 3 will be pulled away (as shown in Figure 10), to not influence to influence cunning of the stretchable removal adhesive tape 1 on intermediary layer 2
It is dynamic.
Specifically, existing low adhesive film or low viscous coating can be used in the above low-viscous layer 3.Alternatively, due to intermediary layer 2
The face (the second face 22) contacted with low-viscous layer 3 is without viscosity, therefore one-faced tapes can also be used in low-viscous layer 3, viscous to have with it
The one side of property clings intermediary layer 2.Certainly, since the adhesion strength between preferred low-viscous layer 3 and stretchable removal adhesive tape 1 is more than
Its adhesion strength between intermediary layer 2, therefore when using one-faced tapes as low-viscous layer 3, the stripping between intermediary layer 2 is strong
Degree cannot be too big, usually can in 1 gram inch between 200 gram inch, more preferably in 1 gram inch between 100 gram inch,
Further preferably in 0.5 gram inch between 50 gram inch.
A kind of specific implementation mode according to the present invention, Adhesive tape assembly further include non-adhesive layer 4, are located at stretchable removal
At least side of at least one end of adhesive tape 1, non-adhesive layer 4 is far from the stretchable face for removing adhesive tape 1 without viscosity.
That is, as shown in fig. 7, can also be equipped with the inviscid layer in outside (its inside in 1 end of stretchable removal adhesive tape
Can toughness to be bonded on stretchable removal adhesive tape 1).As previously mentioned, stretchable removal adhesive tape 1 after bonding must there are one
End stays in except substrate 9, to carry out stretched operation.And before being stretched, to prevent the end from unexpected bonding occurs,
Therefore it can have disposed thereon non-adhesive layer 4 (effect is similar to release film).Position, length of the non-adhesive layer 4 etc. can be according to specific
Need to determine, if for example, as shown in Figure 8 it is stretchable remove adhesive tape 1 end can be folded over to come and be bonded in the first substrate 91,
As long as then it does not carry out cohesive side and is equipped with non-adhesive layer 4.Specifically, the non-adhesive layer 4 can be known inviscid
Film (such as release film), non-stick coating layer, one-faced tapes, are not described in detail herein.
Wherein, although the low-viscous layer 3 more than being depicted simultaneously in Fig. 7 to Figure 10 and non-adhesive layer 4, between the two
Have no positive connection.In one Adhesive tape assembly product, can have low-viscous layer 3 and non-adhesive layer 4 simultaneously, it also can be only therein
It is a kind of.
Wherein, on the outside of the stretchable removal adhesive tape 1 (intermediary layer 2, non-adhesive layer 4), can also be equipped with conventional release film or
Release paper prevents it from unexpected bond occurs for protecting adhesive surface 11 when not in use.
In the part attached drawing of the embodiment of the present invention, intermediary layer 2, low-viscous layer 3, non-adhesive layer 4 etc. are to be recessed to draw
Stretch remove adhesive tape 1 inside, but this merely to schematically indicate these structures should be located at it is stretchable removal adhesive tape 1 which
Side, and do not represent the recess being actually equipped in stretchable removal adhesive tape 1 for accommodating these structures.
Bonded product
The embodiment of the present invention also provides a kind of bonded product comprising：
First substrate 91 has the first face to be bonded；
Stretchable removal adhesive tape 1, with adhesive surface 11, the stretchable part for removing adhesive tape 1 is bonded in first and waits gluing

From the above various embodiments as it can be seen that when the Ra values in the second face of intermediary layer are in the range of 0.1 μm to 7 μm, Ra is removed
Being worth maximum embodiment 8 has individual sample fracture outer, and other all stretchable removal adhesive tapes all can be smoothly removed without sending out
Raw fracture.This shows that the roughness in range above can effectively avoid stretchable removal adhesive tape and is pulled off really.If moreover, Ra values
It is unfavorable to avoiding the stretchable fracture for removing adhesive tape, therefore the Ra values in the second face of the above intermediary layer are preferably smaller than 6 μ when excessive
M, more preferably less than 5 μm.
Correspondingly, from above each comparative example as it can be seen that respectively when the Ra values in the second face of intermediary layer are less than 0.1 μm, then machinery is drawn
Stretchable removal adhesive tape majority is all pulled off in stretching, and then all stretchable removal adhesive tape can be all pulled off in stretching by hand.And
In practical applications, it is not generally possible to the result ability that stretchable removal adhesive tape is removed, therefore is stretched by hand slowly using machinery
More there is referential.This shows to think that roughness is smaller in traditional concept, and the smaller idea of resistance to sliding is incorrect, if
Two surface roughness are too low, also result in stretchable removal adhesive tape and are pulled off.
It can be seen that whether it is what, by polishing that no matter intermediary layer is what material, intended use, but as long as its
The roughness in two faces be in more than particular range in, you can play and preferably avoid stretchable removal adhesive tape during removal
The effect being pulled off；As long as and its roughness exceed the range, it is whether excessive or too small, be easy to cause stretchable removal
Adhesive tape is pulled off.This shows mode only according to the invention, and the roughness in the second face of intermediary layer is controlled in the particular range
It is interior, it can be only achieved and avoid stretchable removal adhesive tape breaking, improve the effect of its reliability.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, however the present invention is not limited thereto.For those skilled in the art, in the essence for not departing from the present invention
In the case of refreshing and essence, various changes and modifications can be made therein, these variations and modifications are also considered as protection scope of the present invention.
