adhesive tape assembly
As shown in Figures 3 to 10, embodiments of the invention provide a kind of Adhesive tape assembly, and it is for being bonded at least one substrate 9, and Adhesive tape assembly comprises:
Can remove adhesive tape 1 by stretching and shifting, it has adhesive surface 11;
Media layer 2, its covering can stretching and shifting except at least part of adhesive surface 11 of adhesive tape 1, and there is relative first surface 21 and the second face 22; Wherein,
First surface 21 is for boning with substrate 9;
Second face 22 is bonded on adhesive surface 11, and has at least part of second face 22 directly to contact with adhesive surface 11;
Second face 22 has the Ra value 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 comprise conventional can stretching and shifting except adhesive tape 1, this can be provided with adhesive surface 11 (i.e. the sticking face of tool) for boning with substrate 9 except at least one face of adhesive tape 1 by stretching and shifting.Adhesive surface 11 be coated with media layer 2 at least partially, media layer 2 is the second face 22 towards the side of adhesive surface 11, there is specific roughness in second face 22, i.e. its Ra value (profile arithmetic mean deviation, arithmeticalmeandeviationoftheprofile) between 0.1 μm to 7 μm, and part second face 22 is had at least to be directly contact with adhesive surface 11; And the opposite side of media layer 2 is first surface 21, this first surface 21 is for being bonded in substrate 9.
When Adhesive tape assembly is bonded in substrate 9, media layer 2 can stretching and shifting except between adhesive tape 1 and substrate 9, become " intermediary " of the two, and have specific roughness the second face 22 can with can contact except adhesive tape 1 (adhesive surface 11) by stretching and shifting.Thus as shown in Figure 5, to can stretching and shifting stretch except adhesive tape 1 time, can be separated with media layer 2 except adhesive tape 1 and to slide on this second face 22 by stretching and shifting, namely originally can removing the slip of adhesive tape 1 in substrate 9 and become the slip on the second face 22 by stretching and shifting.The beat all discovery of the present invention, if with can have specific roughness in the face (the second face 22) that contact except adhesive tape 1 of stretching and shifting, then itself and can stretching and shifting except the sliding resistance between adhesive tape 1 just lower.Therefore, above media layer 2 can reduce can the sliding resistance that is stretched when removing suffered by (when especially draw angle is larger) except adhesive tape 1 of stretching and shifting, thus avoids being pulled off except adhesive tape 1 by stretching and shifting, improves the reliability of Adhesive tape assembly.
Why have specific roughness face and can stretching and shifting except the sliding resistance between adhesive tape 1 lower, may be due to following reason (restriction of following statement not to action principle of the present invention): when can stretching and shifting be stretched except adhesive tape 1 time, there is height-oriented and surface undulation and be eliminated to a great extent in its surface molecular, can can become the very low shiny surface of roughness except adhesive tape 1 surface by stretching and shifting, if the face be now in contact with it is also very smooth, the contact area between the two is very large, cause still having certain viscosity can stretching and shifting can be well-bonded with this face except adhesive tape 1, sliding resistance increases.Accordingly, if with can the face that contact except adhesive tape 1 of stretching and shifting too coarse, then easily can be scratched by the spike of coarse structure in sliding process except adhesive tape 1 by stretching and shifting, thus cause sliding resistance to increase and make to remove adhesive tape 1 and easily rupture by stretching and shifting.And when roughness is positioned at specified range, the impact of above two aspects can be made to reach balance, sliding resistance dropped to minimum, best avoiding can be pulled off except adhesive tape 1 by stretching and shifting.
According to a kind of embodiment of the present invention, the second face 22 has the Ra value between 0.15 μm to 6 μm.
That is, this second face 22 preferably has the Ra value between 0.15 μm to 6 μm, more preferably has the Ra value between 0.2 μm to 5 μm, preferably has the Ra value between 0.5 μm to 4 μm further.
Wherein, above can stretching and shifting except adhesive tape 1 can adopt any known can stretching and shifting except adhesive tape product, the 6701-150 type of such as 3M Creative Company (U.S., the Minnesota State, Sao Paulo) can stretching and shifting except adhesive tape, be not described in detail at this.
Wherein, although in the drawings and in which all with can stretching and shifting except every side of adhesive tape 1 be completely adhesive surface 11 as an example, should be appreciated that if can stretching and shifting except the side of adhesive tape 1 in only have portion to be adhesive surface 11, and all the other positions are inviscid, are also feasible.Such as, can there is no viscosity except an end of adhesive tape 1 by stretching and shifting, using as handle when stretching.
Wherein, above media layer 2 can adopt any known rete, as long as its side can be bonded in substrate 9, opposite side has above specific roughness.Preferably, this media layer 2 can be made up of polymer materials, and such as polyimide, polyethylene terephthalate, polycarbonate etc., be not described in detail at this.
And the thickness of media layer 2 generally can at several microns between hundreds of micron, such as, between 5 μm to 800 μm, preferably between 10 μm to 500 μm, more preferably between 20 μm to 200 μm, preferred between 25 μm to 100 μm further.
According to a kind of embodiment of the present invention, first surface 21 is provided with pressure sensitive adhesives 219 or double sticky tape.
That is, because Adhesive tape assembly has part surface to be the first surface 21 of media layer 2, thus to realize Adhesive tape assembly with the bonding of substrate 9, then this first surface 21 will be bonded in substrate 9; Therefore, first surface 21 is preferably provided with pressure sensitive adhesives 219 or double sticky tape.This pressure sensitive adhesives 219 can be conventional Acrylate pressure sensitive binding agent, polyurethane pressure sensitive binding agent, polyvinyl chloride pressure sensitive adhesives etc., is not described in detail at this.
Certainly, if first surface 21 does not have binding agent, but the position will carrying out boning in substrate 9 arranges binding agent or double sticky tape, is also feasible.
According to a kind of embodiment of the present invention, can all have adhesive surface 11 except the both sides of adhesive tape 1 by stretching and shifting, wherein only have on an adhesive surface 11 and be bonded with media layer 2.
That is, as shown in Fig. 3, Fig. 6, can can all there is adhesive surface 11 in both sides except adhesive tape 1 by stretching and shifting, this is because inconvenient occasion of directly being torn from substrate 9 by adhesive tape can be generally used for except adhesive tape 1 by stretching and shifting, and general adhesive tape all will be bonded between two substrates 9 in this occasion, therefore preferably can all can bond except the both sides of adhesive tape 1 by stretching and shifting.And due in actual applications, which generally can determine will remove and direction can should stretch (can only stretch upward in as Figure 10) to except during adhesive tape 1 by stretching and shifting in advance, and can only slide the substrate 9 (the first substrate 91 as in Figure 10) near draw direction side is upper except adhesive tape 1 by stretching and shifting, as long as therefore media layer 2 can be provided with in this side except adhesive tape 1 by stretching and shifting.
According to a kind of embodiment of the present invention, media layer 2 can be there is no except at least one end of adhesive tape 1 by stretching and shifting.
That is, as shown in Fig. 3, Fig. 7, above media layer 2 can be set stretching and shifting except at least one end of adhesive tape 1.This is because remove can stretching and shifting except adhesive tape 1 time, first make to be separated with media layer 2 except adhesive tape 1 by stretching and shifting, to ensure to slide to reduce sliding resistance on media layer 2 except adhesive tape 1 by stretching and shifting.And if can also have media layer 2 except the end of adhesive tape 1 by stretching and shifting, then the end of the two flushes as shown in Figure 6, therefore is at this moment difficult to the two be separated in end.
According to a kind of embodiment of the present invention, can remove on the length direction of adhesive tape 1 by stretching and shifting, the size of the part that the second face 22 directly contacts with adhesive surface 11 is at least 5 millimeters.
That is, can remove in the media layer 2 that adhesive tape 1 is arranged by stretching and shifting, the second face 22 directly contacted with adhesive surface 11 will to the youthful and the elderly 5 millimeters (also can have between part second face 22 and adhesive surface 11 and be provided with other structure).This is because when stretching, actual only have substrate 9 edge part and can stretching and shifting comparatively large except the sliding resistance between adhesive tape 1, therefore at least must be provided with the media layer 2 (the second face 22) directly contacted with adhesive surface 11 in this position.And the present invention finds, the general length of the part that above sliding resistance is larger is within 5 millimeters, therefore the second face 22 directly contacted with adhesive surface 11 should to the youthful and the elderly 5 millimeters.Certainly, if the second face 22 length directly contacted with adhesive surface 11 is longer, thus better playing the effect reducing sliding resistance, is also feasible.
According to a kind of embodiment of the present invention, on the adhesive surface 11 being bonded with media layer 2, along can stretching and shifting except the length direction of adhesive tape 1, media layer 2 only covers a part for this adhesive surface 11; Or, on the adhesive surface 11 being bonded with media layer 2, along can stretching and shifting except the length direction of adhesive tape 1, media layer 2 covers this adhesive surface 11 completely.
That is, with on the adhesive surface 11 of media layer 2, media layer 2 as shown in Figure 3, can only cover a part for this adhesive surface 11.This is because as previously mentioned, length is less in fact for the higher part of sliding resistance, as long as therefore this part adhesive face 11 is provided with media layer 2, other position remains and can directly bond with substrate 9 except the adhesive surface 11 of adhesive tape 1 by stretching and shifting like this, can ensure as far as possible can stretching and shifting except the adhesive property of adhesive tape 1 script constant.
Or, also can as shown in Figure 6, if certain adhesive surface 11 is with media layer 2, then media layer 2 just covers this adhesive surface 11 completely.Obviously, if media layer 2 be only positioned at can stretching and shifting except the portion of adhesive tape 1, must carry out careful contraposition when attaching, to ensure that media layer 2 is positioned at the edge part (otherwise media layer 2 does not just have the effect reducing sliding resistance) of substrate 9, its operation easier is very large.And if media layer 2 covers whole adhesive surface 11, its operation is just simpler.
According to a kind of embodiment of the present invention, can stretching and shifting except on the width of adhesive tape 1, the size of media layer 2 be more than or equal to can stretching and shifting except the width of adhesive tape 1.
Obviously, from reduction sliding resistance and angle easy to use consider, the second face 22 should cover the whole width range of adhesive surface 11, namely as shown in Figure 4, media layer 2 should with can stretching and shifting except adhesive tape 1 with wide or wider than it.
Certainly, if the width of media layer 2 than can stretching and shifting except the width of adhesive tape 1 little, it also can play the effect of certain reduction sliding resistance.Typically, can be pulled off except adhesive tape 1 by stretching and shifting to reliable avoiding, then media layer 2 width at least should be can stretching and shifting except 30% of adhesive tape 1 width, be more preferably at least 50%, be preferably at least 80% further.Obviously, media layer 2 width be less than can stretching and shifting except adhesive tape 1 width time, its preferably should be located at can stretching and shifting except the middle part of adhesive tape 1 width.
According to a kind of embodiment of the present invention, Adhesive tape assembly also comprises low-viscous layer 3, and it is located at an end of media layer 2 and can removes between adhesive tape 1 by stretching and shifting; And low-viscous layer 3 and can stretching and shifting except in the cohesive strength between adhesive tape 1 and the cohesive strength between low-viscous layer 3 and media layer 2, have a cohesive strength be less than between media layer 2 and substrate 9 at least.
That is, as shown in Figure 7, an end of media layer 2 and can stretching and shifting except being also provided with low-viscous layer 3 between adhesive tape 1 (obviously, be provided with the position of low-viscous layer 3, then the second face 22 does not directly contact with adhesive surface 11), this low-viscous layer 3 has lower cohesive strength, thus ensure itself and can stretching and shifting except the cohesive strength between adhesive tape 1 and/or the cohesive strength between itself and media layer 2 lower than the cohesive strength between media layer 2 and substrate 9.Thus, the effect of this low-viscous layer 3 makes media layer 2 and can be less than cohesive force between media layer 2 and substrate 9 except the separation stresses between adhesive tape 1 by stretching and shifting, thus removing in process, can ensure necessarily can be separated with media layer 2 except adhesive tape 1 by stretching and shifting, and can not produce media layer 2 along with can stretching and shifting except adhesive tape 1 is together by situation about peeling off from substrate 9.
According to a kind of embodiment of the present invention, low-viscous layer 3 and cohesive strength between low-viscous layer 3 and media layer 2 can be greater than except the cohesive strength between adhesive tape 1 by stretching and shifting.
That is, as preferred mode, low-viscous layer 3 and can stretching and shifting except the cohesive strength between adhesive tape 1 comparatively large, and and cohesive strength between media layer 2 less.Like this can stretching and shifting except adhesive tape 1 be separated with media layer 2 time, low-viscous layer 3 will inevitably be bonded in can stretching and shifting except adhesive tape 1 is separated with media layer 2, along with can being pulled away (as shown in Figure 10) except the continuation stretching low-viscous layer 3 of adhesive tape 1 by stretching and shifting, thus do not affect can affect can stretching and shifting except the slip of adhesive tape 1 on media layer 2.
Concrete, above low-viscous layer 3 can adopt existing low adhesive film or low viscous coating.Or the face (the second face 22) contacted with low-viscous layer 3 due to media layer 2 does not have viscosity, therefore low-viscous layer 3 also can adopt one-faced tapes, to be clung by media layer 2 by its sticking one side.Certainly, due to preferred low-viscous layer 3 and cohesive strength between itself and media layer 2 can be greater than except the cohesive strength between adhesive tape 1 by stretching and shifting, therefore when using one-faced tapes as low-viscous layer 3, stripping strength between itself and media layer 2 can not be too large, usually can between 1 gram/inch to 200 grams/inch, more preferably between 1 gram/inch to 100 grams/inch, preferred between 0.5 gram/inch to 50 grams/inch further.
According to a kind of embodiment of the present invention, Adhesive tape assembly also comprises non-adhesive layer 4, its be located at can stretching and shifting except at least side of at least one end of adhesive tape 1, non-adhesive layer 4 is away from can not having viscosity except the face of adhesive tape 1 by stretching and shifting.
That is, as shown in Figure 7, can stretching and shifting except adhesive tape 1 end also can be provided with the noncohesive layer in outside (inside it can toughness be bonded in can stretching and shifting except on adhesive tape 1).As previously mentioned, can an end must be had after bonding to stay except substrate 9, to carry out stretched operation except adhesive tape 1 by stretching and shifting.And before stretching, be the bonding preventing this end from meeting accident, therefore non-adhesive layer 4 (effect is similar to release film) can be set thereon.The position, length etc. of this non-adhesive layer 4 can determine according to specific needs, such as, if can bend and be bonded in the first substrate 91, as long as then its side of not carrying out boning is provided with non-adhesive layer 4 except the end of adhesive tape 1 by stretching and shifting as shown in Figure 8.Concrete, this non-adhesive layer 4 can be known inviscid film (as release film), non-stick coating layer, one-faced tapes etc., is not described in detail at this.
Wherein, although depict above low-viscous layer 3 and non-adhesive layer 4 in Fig. 7 to Figure 10 all simultaneously, between the two, there is no positive connection.In an Adhesive tape assembly product, low-viscous layer 3 and non-adhesive layer 4 can be had simultaneously, also can only have one wherein.
Wherein, adhesive tape 1 (media layer 2, non-adhesive layer 4) outside can be removed by stretching and shifting, also can being provided with conventional release film or separate-type paper, for protecting adhesive surface 11 when not using, preventing the bonding that it meets accident.
In the part accompanying drawing of embodiments of the invention, media layer 2, low-viscous layer 3, non-adhesive layer 4 etc. be recessed can stretching and shifting except adhesive tape 1 inside, but this be only in order to schematically represent these structures should be positioned at can stretching and shifting except which side of adhesive tape 1, and do not represent can stretching and shifting except the actual depression be provided with for holding these structures in adhesive tape 1.
