Embodiment
Then, the mode for implementing the present invention is illustrated based on accompanying drawing.
The embodiment ＞ of ＜ the 1st
As illustrated in figure 1, pressure sensitive adhesion sheet 10 possesses：It is stripping film 11, opposed with its with one side in the stripping film 11
Mode be laminated net 12, with the mode opposed with the another side of the net 12 be laminated have extensibility and flexibility foaminess
Base material 13 and installed and by stripping film 11 and the pressure sensitive adhesive layer 14 of the lamination adhesive of net 12 between stripping film 11 and net 12.
It is that above-mentioned pressure sensitive adhesive layer 14 is coated on stripping film 11 with net 12 opposed faces entire surface and with by the mesh 12a of net 12
The mode of blocking is constituted.In addition, for stripping film 11, although do not illustrate, but pass through the contact adhesive in lamination adhesive
The face of layer 14 forms the paper of the peeling agent layer of silicon-type, polypropylene etc. to constitute via joint filling oxidant layer.Due to the stripping
The presence of oxidant layer so that stripping film 11 is easily peeled off from pressure sensitive adhesive layer 14.And then by by above-mentioned stripping film 11, pressure
Compressed under the state (Fig. 1 (a)) that sensitive adhesive layer 14, net 12 and foaminess base material 13 are laminated, pressure sensitive adhesive layer 14 enters
Network 12 mesh 12a and fill, pressure sensitive adhesive layer 14 is crimped on foaminess base material 13 (Fig. 1 (b)).
For net 12, in the present embodiment, comprising by thermoplastic resin be made through fiber 12c and latitude fiber 12d
It is arranged as one layer of reticulate body 12b of clathrate or is made up of it.Specifically, net 12 is as former state using will be by thermoplastic resin system
Into made up through fiber 12c and latitude fiber 12d after one layer of reticulate body 12b formed by thermo-compression bonding., can as thermoplastic resin
Include the polyolefin of polyethylene, polypropylene etc., polyethylene terephthalate, polyamide, polyvinyl alcohol, polyacrylonitrile,
Polyurethane, halogen prime system polymer etc..In addition, in the embodiment, because net 12 is comprising one layer of reticulate body 12b or by its structure
Into, therefore the mesh 12a and reticulate body 12b of net 12 opening portion 12e are consistent.And then, reticulate body 12b opening portion 12e is preferred
To be generally square.
Thickness and width in the cross section through fiber 12c of the reticulate body 12b by net 12 is constituted is set to A1And B1
When, the flatness B through fiber 12c1/A1It is set in the range of 10~60, (Fig. 1~figure in the range of being preferably set to 15~40
3).In addition, the thickness and width in the latitude fiber 12d of the reticulate body 12b by net 12 is constituted cross section is set to A2And B2
When, latitude fiber 12d flatness B2/A2It is set in less than 60 scope, is preferably set in less than 40 scope, more preferably
It is set in the range of 10~60, is further preferably set in the range of 15~40.Wherein, by the flatness through fiber 12c
B1/A1Be in the range of being limited to 10~60 because：If less than 10, net 12 described later follows angle excessively to diminish, net 12
Float from foaminess base material 13, net 12 is reduced for the adaptation of foaminess base material 13, if it exceeds 60, then reticulate body 12b
Opening portion 12e is excessively tailed off, and pressure sensitive adhesive layer 14 is reduced for the adhesion of foaminess base material 13, with flatness less than 10
Similarly, net 12 floats situation from foaminess base material 13 in following angle to test.In addition, by latitude fiber 12d flatness B2/
A2Be defined to 60 the following is because：If it exceeds 60, reticulate body 12b opening portion 12e excessively tail off, 14 pairs of pressure sensitive adhesive layer
Reduced in the adhesion of foaminess base material 13.
In addition, reticulate body 12b opening portion 12e horizontal length is being set into G1(mm) when, G1It is preferably set to 3~
In the range of 7mm.In addition, reticulate body 12b opening portion 12e longitudinal length is set into G2(mm) when, G2It is preferably set to 3
In the range of~7mm.And then, the reticulate body 12b thickness through fiber 12c and latitude fiber 12d is preferably set in 2 respectively~
In the range of 100 μm, more preferably it is set in the range of 20~80 μm.Wherein, by opening portion 12e horizontal length G1With open
Oral area 12e longitudinal length G2Be each defined in the range of 3~7mm be because：If less than 3mm, contact adhesive
Layer 14 is reduced for the adhesion of foaminess base material 13, if it exceeds 7mm, even if then net 12 is laminated, foaminess base material 13
Dimensional stability is not also improved.In addition, the reticulate body 12b thickness through fiber 12c and latitude fiber 12d is each defined in 2~
Be in the range of 100 μm because：If less than 2 μm, because net 12 is excessively thin, fold is easily produced in manufacturing process, if super
100 μm are crossed, then net 12 becomes thicker than pressure sensitive adhesive layer 14, the adaptation of foaminess base material 13 and pressure sensitive adhesive layer 14 becomes
Difference.
Figure 4 illustrates the assay method for following angle of net 12.First, width and length cut out as 50mm respectively and
300mm.Now, cut out in the way of net 12 is through directions of the fiber 12c as length 300mm.Then, by pressure sensitive adhesion sheet 10
Half cycle is only wound in the outer peripheral face of diameter 100mm or 25mm cylinder 16, so that the foaminess base material 13 of pressure sensitive adhesion sheet 10
Face connects with cylinder 16.Now, by the two sides adhesive tape 17 for the outer peripheral face for being pasted on cylinder 16 in advance, pressure-sensitive adhesion is made
Outer peripheral face only its closely sealed half cycle of the foaminess base material 13 of piece 10 in cylinder 16.And then, make the foaming of pressure sensitive adhesion sheet 10
The property face of base material 13 is sealed in the state of cylinder 16, and the stripping film 11 of pressure sensitive adhesion sheet 10 is peeled off, be placed after 1 minute,
The angle, θ of the part contacted with foaminess base material 13 is determined in the case where net 12 is not peeled off from foaminess base material 131.Should
What angle was set to net 12 follows angle, θ1.This follows angle, θ1More become big, i.e., closer to 180 degree, then followability is better, more becomes
Small, then followability is more reduced.
On the other hand, it is lower aobvious using heating as the contact adhesive 21 (Fig. 5) of the raw material as pressure sensitive adhesive layer 14
Show pressure-sensitive-adhesive and play the EVA systems hot melt adhesive of excellent cementability, rubber series heat molten type bonding at room temperature
The aqueous pressure-sensitive adhesive and acrylic acid of agent, acrylic emulsions, EVA emulsions, SBR emulsion, vinylacetate system emulsion etc.
Solvent system contact adhesive of system, EVA systems, SBR systems, vinylacetate system etc. etc..In addition, as foaminess base material 13, using
EPDM (Ethylene Propylene Diene Terpolymer) foam with extensibility and flexibility, carbamate bubble
Foam, polyethylene etc..Compressive hardness during 40% compression of the foaminess base material 13 is preferably set to 5~200N/314cm2
In the range of.Wherein, the preferred scope of compressive hardness during 40% compression of foaminess base material 13 is defined to 5~200N/
314cm2In the range of be because：If less than 5N/314cm2, foaminess base material 13 is excessively soft, it is impossible to from pressure sensitive adhesion sheet 10
Stripping film 11 is peeled off, if it exceeds 200N/314cm2, then foaminess base material 13 is really up to the mark, and net 12 is close with foaminess base material 13
Conjunction property is deteriorated.
One of the manufacture method of pressure sensitive adhesion sheet 10 so constituted is illustrated based on Fig. 1 and Fig. 5.But, and
It is not limited to the manufacture method.First, after the one side of stripping film 11 is all coated with contact adhesive 21 (Fig. 5), drying is used
Machine 22 (Fig. 5) dries contact adhesive 21, and thus contact adhesive 21 turns into pressure sensitive adhesive layer 14, on the upper strata of stripping film 11
Folded pressure sensitive adhesive layer 14.Then one side, in stripping film 11, the face cascade net 12 for being laminated pressure sensitive adhesive layer 14.By
Pressure sensitive adhesive layer 14 is strippingly adhered to stripping film 11 by this, while the one side of net 12 is adhered into pressure sensitive adhesive layer
14.In this condition in the another side stacking foaminess base material 13 (Fig. 1 (a)) of net 12.And then with roller 23,23 by the stripping of stacking
Film 11, pressure sensitive adhesive layer 14, net 12 and foaminess base material 13 are compressed.Thus pressure sensitive adhesive layer 14 enters 12 mesh that networks
12a and fill, pressure sensitive adhesive layer 14 is crimped on foaminess base material 13 (Fig. 1 (b)).For the pressure sensitive adhesion sheet so manufactured
For 10, contact adhesive 21 is not coated on to the two sides of net 12, and is simply coated on the one side of stripping film 11, it becomes possible to is made
Make the pressure sensitive adhesion sheet 10 being made up of the layered product of stripping film 11, pressure sensitive adhesive layer 14, net 12 and foaminess base material 13.It is tied
Really, can simplify the apparatus for coating of the contact adhesive 21 in the manufacturing process of pressure sensitive adhesion sheet 10.
For the pressure sensitive adhesion sheet 10 so manufactured, because the reticulate body 12b with flexible net 12 is through fiber
12c flatness B1/A1It is in the range of 10~60, even if therefore the pressure sensitive adhesion sheet 10 is pasted in a direction than larger
Above face is attached so that following the curved surface through fiber 12c and bending, pressure sensitive adhesion sheet 10 with the small curved surface of radius of curvature
It is difficult to peel off from the face that is attached, 10 pairs of followability for being attached face of pressure sensitive adhesion sheet are good.On the other hand, due to making that there is flexibility
Net 12 reticulate body 12b latitude fiber 12d flatness B2/A2As less than 60, therefore include latitude fiber 12d flatness
B2/A2For than the flatness B through fiber 12c1/A1The small situation less than 10.But, even if latitude fiber 12d flatness B2/A2
Less than 10, if pressure sensitive adhesion sheet 10 is pasted on have in one direction the small curved surface of radius of curvature be attached face so that through
Fiber 12c follows the curved surface and bent, and is glued in the state of extending due to the crest line that curved surface is followed in latitude fiber 12d on straight line
Patch, therefore do not influence latitude fiber 12d to the followability for being attached face of pressure sensitive adhesion sheet 10, pressure sensitive adhesion sheet 10 is kept well
Followability to being attached face.
The embodiment ＞ of ＜ the 2nd
Fig. 6~Fig. 8 represents the 2nd embodiment of the present invention.In Fig. 6, same portion is represented with Fig. 1 identical references
Part.In the embodiment, net 60 is included and is arranged as by what thermoplastic resin was made through fiber 61a, 62a and latitude fiber 61b, 62b
The the 1st and the 2nd double-deck reticulate body 61,62 of clathrate is made up of them.In addition, with the 1st reticulate body 61 through fiber 61a and
Latitude fiber 61b is constituted with the 2nd reticulate body 62 through fiber 62a and latitude fiber the 62b mode not overlapped on same line.
In order to make above-mentioned net 60, first in the same manner as the reticulate body of the 1st embodiment, by what is be made up of thermoplastic resin
It is thermally compressed after being made up respectively through fiber 61a, 62a and latitude fiber 61b, 62b and makes the 1st and the 2nd reticulate body 61,62.Then, lead to
Crossing makes the 2nd reticulate body 62 be moved in parallel relative to the 1st reticulate body 61, with the 1st reticulate body 61 through fiber 61a and latitude fiber 61b
The mode not overlapped with the 2nd reticulate body 62 on same line through fiber 62a and latitude fiber 62b is by the 1st and the 2nd reticulate body
61st, 62 stacking.And then, the 1st and the 2nd reticulate body 61,62 that this has been laminated is thermally compressed.So make net 60.In addition, the implementation
In mode, constituted due to net 60 comprising the 1st and the 2nd double-deck reticulate body 61,62 or by them, therefore the mesh of net 60 and the 1st
And the 2nd reticulate body 61,62 opening portion 61c, 62c it is inconsistent.In addition, mesh and the opening portion of reticulate body 61,62 of net 60
61c, 62c are preferably respectively generally square.
It is explained, the method under net can be used to makes.First, the film of 2 Rotating fields is cut by cutting machine, makes it wide
Degree broadens.Then the wide film stretching of above-mentioned width is provided by multiplying power in warm bath by one-off drawing machine.Then, drawn by secondary
Machine is stretched in hot blast further by film stretching regulation multiplying power.By the vertical stretching process, film becomes easy cracking.And then, pass through
Cut fine (cutting fibre) instrument the film stretched is carried out cutting fibre in the vertical.Thus, cutting the film of fibre regularly turns into mesh-shape.It is logical
Cross broadening degree device and the film for cutting fibre is spread into defined width or width of mesh in the horizontal, as vertical knitmesh (ウ エ
ブ)。
On the other hand, the mould of other 3-tier architecture is extended down to by regulation multiplying power by stack, be orientated in the vertical.It is logical
Crossing calendering makes film extend 1.1~5 times or so.Due to the length for making film by it only extend with the corresponding part of calendering, therefore
Linear velocity is accelerated.Then, the film being orientated in vertical elongation and longitudinally oriented process is imported into slitter and support roller (by け ロ ー
Le) between, formed in the part for the both sides for not including film along horizontal slit.Then, will be in horizontal shape by horizontal stretching device
Film into slit is further stretched in the horizontal.Thus, film, which turns into, forms netted horizontal knitmesh.
Then, above-mentioned vertical knitmesh and above-mentioned horizontal knitmesh are imported between laminating roll and guide-in roller.Now, guide etc. is passed through
Imported in the state of horizontal knitmesh is tensioned in the horizontal., will under appropriate tension force in the horizontal knitmesh of the state being tensioned
Vertical knitmesh is imported, and horizontal knitmesh is extruded to laminating roll.Thus, indulge knitmesh to extrude horizontal knitmesh to laminating roll, then, use distributing roller
Crimped.During this period, appropriate heat treatment is carried out to horizontal knitmesh.Thus net is manufactured.

Opening portion 62c horizontal length g3With the length g of longitudinal direction4Be each defined in the range of 3~7mm be because：If less than
3mm, then pressure sensitive adhesive layer 14 reduced for the adhesion of foaminess base material 13, if it exceeds 7mm, even if then by 60 layers of net
Folded, the dimensional stability of foaminess base material 13 will not also be improved.In addition, by the 1st reticulate body 62 through fiber 61a and latitude fiber
The thickness through fiber 62a and latitude fiber 62b of 61b thickness and the 2nd reticulate body 62 is each defined in 2~100 μm of scope
Be inside because：If less than 2 μm, because net 12 is excessively thin, therefore the easily generation fold in manufacturing process, if it exceeds 100 μm,
Then net 12 becomes thicker than pressure sensitive adhesive layer 14, and the adaptation of foaminess base material 13 and pressure sensitive adhesive layer 14 is deteriorated.

Follow the curved surface through fiber 61a and bend, even if or following the curved surface with the latitude fiber 61b of the 1st reticulate body 61 and bending
Mode paste, pressure sensitive adhesion sheet 50 is also difficult to peel off from the face that is attached, and 50 pairs of followability for being attached face of pressure sensitive adhesion sheet are good
It is good.
On the other hand, due to making the flatness b through fiber 62a of the 2nd reticulate body 62 with flexible net 603/a3And latitude
Fiber 62b flatness b4/a4It is identical and for less than 60, therefore the flatness b through fiber 62a comprising the 2nd reticulate body 623/
a3With latitude fiber 62b flatness b4/a4For the flatness b through fiber 61a than the 1st reticulate body 611/a1With latitude fiber 61b's
Flatness b2/a2The small situation less than 10.Even if the flatness b through fiber 62a of the 2nd reticulate body 623/a3With latitude fiber 62b
Flatness b4/a4Less than 10, if pressure sensitive adhesion sheet 50 to be pasted on to the quilt in one direction with the small curved surface of radius of curvature
Adhesive face is so that the 1st reticulate body 61 follows the curved surface through fiber 61a or latitude fiber 61b and bent, then the 2nd reticulate body 62 not shadow
The followability that 50 pairs of pressure sensitive adhesion sheet is attached face is rung, 50 pairs of followability for being attached face of pressure sensitive adhesion sheet are kept as well.
In addition, by making reticulate body 61,62 be bilayer, the further extensibility of control foaminess base material 13, therefore with the 1st embodiment
Pressure sensitive adhesion sheet compare, excellent in dimensional stability.
