Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a long plate-like body layer and a flexible sheet layer.

[0002]

2. Description of the Related Art As a method for adhering a long plate-like body layer and a flexible sheet layer having pressure-sensitive adhesive properties on at least one surface opposite to the other layer, the method shown in FIG. As shown in FIG. 1, the flexible sheet layer B is formed from a long plate-shaped body layer A and an original roll (not shown) through an auxiliary roll 100.
By advancing in the direction of the arrow, with the long plate-like body layer on the lower side and the flexible sheet layer on the upper side, between the upper and lower pressure-bonding rolls 200 so that the sticking surfaces face each other. A method was used in which the adhered body was adhered while applying pressure, and the obtained adhered body was passed through between the upper and lower take-up pinch rolls 300 and taken out. In addition,
400 is a receiving table.

As the long plate-like body layer and the flexible sheet layer having the adhesive property on the surface of at least one of the above-mentioned layers facing the other layers, the long plate-like body layer itself or the flexible plate layer can be used. Of the flexible sheet layer itself having an adhesive property by heating or the like, or a long plate layer or a flexible sheet layer,
After the adhesive or pressure-sensitive adhesive is applied, it is dry but still sticky, or the long plate-shaped body layer or the flexible sheet layer is provided with a hot-melt type resin layer. For example, a material having an adhesive property when heated is used.

Further, as a method of heating the material of the long plate-like body layer or the flexible sheet layer, if necessary, in order to develop the adhesiveness, far infrared heater heating; flammable gas such as LPG A method of directly applying a flame that burns a gas or passing through a high temperature area near the combustion area; a method of burning a combustible gas or oil and sending air to the heated air; a method of applying steam; A method of passing a material through a heated box; a method of using a heating roll and bringing the material into contact with the heated roll, and the like are used.

As a common drawback of this sticking method, air is trapped between the long plate-like layer A and the flexible sheet layer B and is contained therein. After passing through the pressure bonding roll 200, air is trapped. There are drawbacks that an air layer is formed in the enclosed part, the adhesion is incomplete, and wrinkles are generated so that smoothness cannot be obtained.

The occurrence of such air entrainment is caused by the long plate-shaped body layer A and the flexible sheet when the long plate-shaped body layer A and the flexible sheet layer B are supplied to the pressure roll 200. Due to the difference in the tension applied to the layer B, the layer having the higher tension, or in the case of a flexible sheet layer such as a foam having a thickness of several mm, the flexible sheet layer may be narrowed in the width direction. Due to the fact that the layer is stretched in the traveling direction of the layer, the layer becomes wavy in the width direction, its peaks and valleys grow in the traveling direction, and the unevenness thus generated is always It is not located at a fixed position, but is caused by a large number formed in the width direction and the traveling direction.

For example, the case where the layer having a corrugated shape is the flexible sheet layer B will be further described. When the flexible sheet layer B is attached to the long plate-like layer A by the pressure bonding roll 200, the pressure bonding roll 200 is contacted. Prior to this, as shown in FIG. 16, the valley portion B1 of the corrugated flexible sheet layer B closest to the long plate layer A first comes into contact with the long plate layer A, On the other hand, the mountain portion B2 farthest from the long plate-shaped body layer A does not contact the long plate-shaped body layer A. In this state, because the pressure-sensitive adhesive rolls 200 are laminated and adhered, air is trapped in the adhered body or wrinkles are formed.

Further, in the case of laminating and sticking the adhesive-coated one, in addition to the above, the unevenness caused by the difference in the coating amount in the width direction and the advancing direction also causes air entrapment and entrapment, which causes sticking. Air may be trapped in the body or wrinkles may form.

In addition, in the case of being adhered by heating, under the influence of the heat, expansion and contraction occur in the long plate layer A and the flexible sheet layer B, and the volume changes, When the tension is changed, waviness is generated, which causes air to be trapped and contained, and the air may be trapped in the adhesive body or wrinkles may be formed.

Further, in the above-mentioned sticking method, as the flexible sheet layer B, those having different thicknesses in the width direction and the advancing direction, for example, the surface layer which is not stuck even if the sticking surface side is smooth Profile (concave / convex slice processing, etc.) processed on the part side (FIG. 17 (a)); the thickness does not change in the traveling direction, but the thickness differs in the width direction, Geta tooth-shaped irregularities (Fig. 17 (b)) or processed into a corrugated shape; the thickness does not change in the width direction, but the thickness differs in the traveling direction, for example, the shape of the cross section in the traveling direction is a geta tooth shape. When unevenness (FIG. 17C) or a corrugated product; etc. is used, the pressure applied to the thin portion is insufficient in sticking by the pressure bonding roll 200 and the sticking is locally defective. Is likely to occur. Moreover, if an attempt is made to pressurize the thin portion, the pressure applied to the thick portion increases, and the adhesive body is crushed, or the crushed adhesive body tries to restore and the uniform adhesiveness cannot be obtained. . Moreover, when such an uneven material is used, wrinkles are likely to occur in the flexible sheet layer B of the adhesive body.

Further, even if unevenness is generated in the widthwise direction, the traveling direction, or both directions due to a change in tension at the time of supplying to the long plate-like layer A, air can be contained in the adhesive body,
Wrinkles may form.

Further, the long plate layer A and the flexible sheet layer B
Even if the hardness, density, thickness, and material of the materials are different,
Air may be trapped in the patch or wrinkles may form.

Further, the flexible sheet layer B is cut during the attachment to form a portion where the flexible sheet layer B is not attached to the long plate-like layer A, and then the long plate-like layer A again. When the flexible sheet layer B is adhered to the flexible sheet layer B, the flexible sheet layer B is intermittently adhered to the long plate-shaped body layer A, or when the adhesive sheet is continuously adhered. When the length of the flexible sheet layer B is insufficient during manufacturing of the bonded body and the bonding is interrupted at that portion, the end portion of the flexible sheet layer B is before the bonding by the pressure roll 200. Then, the flexible sheet layer B contracts toward the pressure-bonding roll 200 side and tries to expand in the width direction by the weight of the pressure-sensitive adhesive roll 2.
In the 00 part, since the long plate-shaped body layer A and the flexible sheet layer B are fixed, the flexible sheet layer B does not drop uniformly on the long plate-shaped body layer A, and As shown in 16, a space 500 is formed. Further, as shown in FIG. 18, a portion B3 of the flexible sheet layer B farther from the pressure roll 200 is first dropped onto the long plate-like layer A (the flexible sheet layer B at this time). The adhesion part between the long plate-shaped body layer A is 700),
There may be a space 600. Such a space 5
When 00 or the space 600 is formed, the air accumulated in the space 500 or the space 600 is caught in the sticking body at the time of stacking and sticking with the pressure bonding roll 200. Also,
In the case of the space portion 600, the flexible sheet layer B is stretched in the direction opposite to the advancing direction at the time of laminating and attaching, but the attaching portion 70
The part of 0 may be wrinkled without being stretched.

Furthermore, the thickness of the long plate layer A is 0.27 to
The adhesive body was manufactured in the same manner by changing the distance between 1.2 mm and changing the constitution of the brush 1 as described below. Width direction 1000 mm × longitudinal direction 100 mm × 1 width direction 1000 mm × longitudinal direction 100 mm × 2 width direction 1000 mm × longitudinal direction 20 mm × 10 width direction 1000 mm × longitudinal direction 20 mm × 15 width direction 1000 mm × longitudinal direction 20 mm × 20 As a result, in any combination, immediately after cutting the flexible sheet layer B, the flexible sheet layer B is instantly laminated and adhered to the long plate-like body layer A by the bristle pressure of the brush 1, and the entrainment of air. No wrinkles, no adhesion through space was observed.

Comparative Example 1 As shown in FIG.
In the same manner as in Example 1 except that the conventional pressure roll 200 was used in place of the brush 1 and the receiving roll 2 in the above, the flexible sheet layer B was intermittently stuck to the long plate-shaped body layer A. The adhered body was manufactured. As a result, the flexible sheet layer B
When the sheet is cut and dropped into the long plate-like layer A, the end B3 of the flexible sheet layer B farther from the pressure bonding roll 200 first drops into the long plate-like body layer A and becomes a space. The part 600 was formed. In addition, the flexible sheet layer B is increased in width due to the cutting to have a wavy shape, and peak portions B2 and valley portions B1 are generated,
A space 500 is provided between the long plate layer A and the flexible sheet layer B.

The adhesive body was produced in the same manner as in Example 1 except that the water-cooling zone formed by forming the water vapor was used, and the water cooling zone including the fountain shower was not used. As a result, a good adhered body was obtained without entrainment of air, generation of wrinkles, adhesion through space, and the like. Further, even if the long plate-like layer A in which the adhesive layer C has uneven coating and the adhesive layer C has some uneven thickness, the flexible sheet layer B is lengthened by the bristle pressure of the brush 1. Since it was pressed against the plate-shaped layer A, a good adhered body was obtained without air being entrapped.

(Example 4) This example is an example of producing an adhesive body in which the flexible sheet layer B is intermittently attached to the long plate-like body layer A by the attaching method of the present invention 2. Is. FIG.
[Fig. 4] is a side view schematically showing the sticking method of the present embodiment. In this example, the same hot-dip galvanized steel sheet as in Example 1 was used as the elongated plate layer A, and the polyethylene foam as in Example 1 was used as the flexible sheet layer B. As the brush 15, the material of the brush portion is palm, the length of the brush portion is 100 mm, the length of the long plate-shaped body layer A in the width direction is 1000 mm, and the length of the long plate-shaped body layer A in the longitudinal direction is One with a length of 200 mm was used. The mounting position of the brush 15 is such that the distance between the bristle tip and the pressure-bonding roll 14 is 10 when the bristle tip flows by pressing the brush 15.
The position was set to be mm. On the other hand, the long plate layer A
Is sent in the direction of the arrow by a delivery pinch roll (not shown), is heated by a heating box (not shown), passes over the table 6, and is supplied to the pressure bonding roll 14 via the brush 15.

Using the apparatus shown in FIG. 13, the flexible sheet layer B is pressed with the brush 15 before the long plate layer A and the flexible sheet layer B are supplied to the pressure roll 14. While excluding air between the flexible sheet layer B and the long plate-shaped body layer A,
The flexible sheet layer B was temporarily adhered to the long plate-shaped body layer A, and then adhered while being pressed by the pressure bonding roll 14.

In this way, when the pressure-sensitive adhesive body with a brush 15 of the brush 15 having a vertical length of 70 mm was obtained, a pressure-sensitive adhesive body without entrapment of air and wrinkles was obtained. Further, the flexible sheet layer B was cut and dropped on the long plate-shaped body layer A, but it was attached to the long plate-shaped body layer A without air entrapment.

Further, instead of the brush 15 described above,
The length of the brush part is 50 mm, the length of the long plate-shaped body layer A in the width direction is 1000 mm, and the length of the long plate-shaped body layer A in the longitudinal direction is 10 mm. The vertical length of the brush portion of the brush 15 at that time was set to 35 mm, but an adhesive body without entrapment of air was similarly obtained.

(Embodiment 5) In this embodiment, as the flexible sheet layer B, a sheet having irregularities on the surface is used. It is an example of manufacturing an adhered body in which the flexible sheet layer B is adhered intermittently.
As the flexible sheet layer B, the same one as that used in Example 2 was used. In the same manner as in Example 2 except that the pressure roll 14 was used instead of the brush 1 and the receiving roll 2, and the brush 15 similar to that in Example 4 was provided before the pressure roll 14. An adhesive body was obtained. 14
[Fig. 4] is a perspective view showing the state of attachment. In this case, the tip of the brush 15 touches both the concave portion and the convex portion, and the bristle pressure presses the flexible sheet layer B toward the long plate-shaped body layer A side, and the brush 15 is evenly attached over the entire surface. It was In the obtained adhered body, the valley portion of the flexible sheet layer B is also the long plate-shaped body layer A.
It was firmly adhered to, and air entrapment and wrinkles were not observed.

(Embodiment 6) In the manufacturing apparatus of Embodiment 3, instead of the brush 1 and the receiving roll 2, the pressure bonding roll 1 is used.
4 was used, and a brush 15 similar to that in Example 4 was provided in front of the pressure roll 14, and the adhesive body adhered with an adhesive in the same manner as in Example 3. Obtained. Air entrapment and wrinkles were not observed in the obtained adherend.

(Embodiment 7) In Embodiment 4, the brush 1
As shown in FIG. 4 (a), the mounting angle of No. 5 was set such that the base 151 of the brush 15 was tilted 30 degrees to the opposite side of the traveling direction, and the flexible sheet layer B was changed to a polyethylene film having a thickness of 0.2 mm. A patch was obtained in the same manner as in Example 4 except for changing the above. Since the flexible sheet layer B has a small thickness, it is likely to change in volume when heated, and when tension is applied too much, the film itself is easily stretched and may be cut in some cases. Therefore, it is preferable to reduce the pressing force for preventing the waviness of the cross section in the width direction at the time of cutting midway because the brush 15 is used.
The angle was set as described above, but air entrapment and wrinkles were not observed in the obtained adherend.
