However, in this method, the pressure-sensitive adhesive layer is provided on the entire surface of the sheets. Therefore, air is accumulated between the adhesive layer and the adherend during the sticking work, and it takes time and time to remove the air, or the air cannot be removed well and the sheet is wrinkled. There was a problem to do. Further, as a major problem, when moisture remains on the surface or inside of the adherend, a blister phenomenon occurs on the sheet and the sticking effect is lost or reduced. This is the case, for example, for waterproofing groundwork on the roof of a building. In this case, moisture such as rainwater remains in the slab concrete of the adherend, and in many cases, moisture also remains inside the new slab concrete. If you place the sheet on the concrete surface and attach the adhesive layer in this state,
As the temperature of concrete rises, water becomes steam, and since there is no escape, the water vapor pushes up the waterproof sheet and appears as a so-called blistering phenomenon. In particular, the amount of solar radiation is large from around May to October, and swelling occurs when it is directly exposed to the rays. Such a phenomenon becomes a major factor of impairing the durability of the waterproof film, which leads to water leakage. As a countermeasure against this, Japanese Utility Model Laid-Open No. 63-54718 proposes a waterproof base material in which a pressure-sensitive adhesive layer is discontinuously provided on the sticking surface of a foam sheet. However, this prior art is limited to obtaining a discontinuous pressure-sensitive adhesive layer by applying a natural rubber-based, chloroprene-based, nitrile-based, or acrylic-based adhesive or pressure-sensitive adhesive to a foamed sheet, which is a specific problem. The formation of the continuous pressure-sensitive adhesive layer is not disclosed, and there is a problem that the discontinuous pressure-sensitive adhesive layer cannot be mass-produced industrially at low cost. In practice, it is difficult to apply the pressure-sensitive adhesive layer discontinuously from the viewpoint of the fluidity of the pressure-sensitive adhesive, and practically only the longitudinal direction of the sheet or the stripe shape in the direction perpendicular to the longitudinal direction is obtained. Even if the island-shaped independent pressure-sensitive adhesive layer is provided, it is difficult to disperse the pressure-sensitive adhesive layer finely on the sheet, and there is a problem that the effect of preventing swelling of air and water vapor becomes poor. .. As a countermeasure for this, a coating method using an engraving roll (gravure roll) or the like can be considered, but the coating thickness is at most 1 from the viewpoint of the viscosity of the adhesive.
Since the limit is about 5 to 20 microns, there is a problem that it is difficult to obtain a predetermined adhesive strength.

The present invention will be specifically described below with reference to the accompanying drawings. 1 to 6 schematically show a method for forming a discontinuous adhesive layer on sheets according to the present invention. Figure 1 is the first
The steps are shown, and a predetermined amount of the adhesive 2 is applied to the entire surface of the release paper (including the film) 1 or the strip shape by an application jig 3 such as a roll knife or a doctor knife. The pressure-sensitive adhesive 2 may be an acrylic type, a nitrile type, a chloroprene type, a polyolefin type, a polyamide type, an ethylene copolymer type, a natural rubber type or the like. Next, the release paper 1 coated with the pressure-sensitive adhesive 2 is heated by a tunnel heating furnace or the like to disperse the vaporized substances contained in the pressure-sensitive adhesive 2 to make the pressure-sensitive adhesive 2 dry to some extent. 2 and 3 show the second step, in which the thin layer mesh pattern body 4 is laminated on the dried pressure-sensitive adhesive 2.
Further, on the thin mesh pattern body 4, the sheets 5 for obtaining the sticking surface are laminated. In this example, the sheets are closed-cell resin sheets. The thin mesh pattern body 4 has a line 40 in the X direction, a line 41 in the Y direction, and a void 42 surrounded by the lines 40, 41, and the shape of the void 42 is as shown in FIG. The shape is arbitrary, such as rectangular or circular. Further, the thin mesh pattern 4 is selected from any material such as synthetic resin film, cloth, and paper, and of course, includes those subjected to release treatment.

FIG. 4 shows the third step, in which the laminate A produced in the second step is pressed in the thickness direction. The pressurization may be performed by a press or the like, or the rolls may be pressed by a pair of upper and lower rolls. By this pressure in the thickness direction, the stripes 40 and 41 of the thin mesh pattern body 4 are brought into close contact with or firmly contact with the release paper 1, and at the same time, the adhesive 2 applied on the release paper 1 is formed by the stripes 40 and 41. It is sheared and flows, filled in the void 42 surrounded by the streaks 40 and 41, and further bonded to the lower surface 50 of the sheet 5 through the void 42. The streaks 40 and 41 are adhered to the release paper 1 via the adhesive 2 that has become extremely thin. After this reduction, the training will be held for the required time. By the third step, as illustrated in FIG. 6, a large number of independent (non-continuous) adhesive layers 6 having a constant shape and a constant array are formed on the sheets 5 respectively, and the adhesive layers 6 are formed.
Between them, grooves 7, 7 running in the X direction and the Y direction are formed. The area and spacing of each pressure-sensitive adhesive layer 6 can be arbitrarily set by the size of the voids 42 of the thin mesh pattern 4 and the width of the stripes 41, and the shape and arrangement of the pressure-sensitive adhesive layer 6 can be set. Can also be freely selected. Further, the thickness of the pressure-sensitive adhesive layer 6 can also be freely controlled by the degree of application of the pressure-sensitive adhesive 2 by the jig 3 such as a roll coater or a doctor knife coater in the first step and the pressure in the third step. In particular, the adhesive layer 6
Is not simply transferred, but is formed by shearing of the thin mesh pattern body 4 and plastic flow of the pressure-sensitive adhesive, so that a thick discontinuous pressure-sensitive adhesive layer 6 exceeding 60 microns can be reliably obtained, and the waterproof base material A self-adhesive layer having a high adhesive strength suitable for a waterproof sheet.

In the present invention, the laminated body after the third step may be used as a product. In this case, when using
Then, the thin mesh pattern 4 is peeled off together with the release paper 1. Since the adhesive is adhered to the surface 50 of the sheets having a higher affinity than the release paper 1, the sheets B having the discontinuous adhesive layer 6 as shown in FIG. 6 are obtained. In some cases, the thin mesh pattern body 4 is peeled off together with the release paper 1 as shown in FIG. 5, and another release paper 1 ′ is attached to the discontinuous adhesive layer 6 as shown by a phantom line to obtain a product. Good. The thin mesh pattern 4 may be reused, or when it is used as a spacer or a reinforcing material by utilizing the extremely thin adhesive layer on the surface, a release paper should be attached to the side opposite to the release paper 1. Good. FIG. 8 shows an example in which the method of the present invention is applied in-line. While the release paper 1 coated with the adhesive 2 and dried is conveyed by a conveyor or the like, a thin layer mesh pattern body 4 wound in a coil shape is formed. The sheet 5 is unwound and superposed on the pressure-sensitive adhesive 2, then passed through pressure rolls 8 to reduce the pressure, and is wound into a coil. Note that the above 2
In the case of a body-separated product, a peeling step may be performed between the pressure rolls 8 and the winder, and the release paper may be wound in a coil shape.
