Description

  The present invention relates to a house such as a roof, a slate, and a metal that is interposed between a roofing roof material and a base plate to maintain the waterproof property of the roof, or to maintain the waterproof property around the opening of the window on the outer wall, etc. The present invention relates to a waterproof material applied to a place where waterproofing is required.

  The waterproof adhesive layer of waterproof tape that is normally used for waterproofing under roof materials or waterproofing around openings such as windows on the outer wall is an elastomer (for example, butyl rubber, acrylic, natural rubber) that is the main component. , Isoprene rubber, styrene butadiene rubber, styrene / butadiene block copolymer, polyisobutylene, silicone rubber, polyvinyl isobutyl ether, chloroprene rubber, nitrile rubber, graft rubber, recycled rubber, or a mixture of these System, mixed system of these and asphalt), tackifier, softener, anti-aging agent, filler, cross-linking agent is added, but in order to adhere to the adherend surface with a strong and permanent adhesive force, The back side of the substrate can be pressed and slid strongly using a rolling roller, or it can be pressed and rubbed by the hand of the operator. It is required.

  However, each time the waterproof material is applied to the adherend surface, there is no problem if the back side of the base material is pressed and slid with the pressure roller. It was extremely troublesome to change and roll each time, and the worker ended up with a slight press with a gloved hand such as a work gloves. Of course, there is an individual difference in the “strength” in the way the operator presses, and even if the operator thinks that the operator has strongly pressed and rubbed, in reality, the waterproof adhesive layer does not sufficiently adhere to the adherend surface for several days ( After about 3 days), it sometimes peeled off, and in such a case, it was possible that rain could not be prevented.

  The present invention is intended to solve the above-described problems, and the object of the present invention is that the waterproof adhesive layer is sufficiently adhered to the adherend surface so that anyone can easily observe the back surface of the substrate. The object is to provide a waterproof material that can be visually recognized.

In order to achieve the above object, the waterproof material according to the present invention is a waterproof material in which a waterproof adhesive layer is formed on one or both surfaces of the substrate, and the waterproof adhesive layer is formed on the outer surface of the substrate on which the waterproof adhesive layer is formed on one surface. the outer surface of the release paper which is temporarily adhered to one of the waterproof adhesive layer formed on both surfaces of either or substrate at the substrate unfriendly paint applying a design, that to facilities a design in paint much filler content or pigment As a feature, it was constructed so that the waterproof adhesive layer can be objectively recognized that the waterproof adhesive layer adheres to the adherend surface when the design becomes thin or disappears due to pressing friction .

According to the waterproof material according to the present invention, in the waterproof material in which the waterproof adhesive layer is formed on one side or both sides of the base material, the waterproof adhesive layer is compatible with the base material on the outer surface of the base material formed on one side. the outer surface of the release paper which is temporarily adhered to one formed on both surfaces of either or substrate subjected to design a bad paint waterproof adhesive layer, because it is characterized in that to facilities a design in paint much filler content or pigment, The operator uses a waterproof material with a waterproof adhesive layer formed on one side of the base material, and after applying the waterproof adhesive layer to the adherend surface, the design (color, letters or pattern) applied to the outer surface of the base material is thin. Or when the change occurs such as disappearing , or after peeling off one release paper of the waterproof material in which the waterproof adhesive layer is formed on both surfaces of the base material and pasting the waterproof adhesive layer on the adherend surface, the other The design applied to the outer surface of the peeling substrate becomes thinner or disappears. Rutoki is to waterproof adhesive layer exhibits an excellent effect of sufficiently close contact with the adherend surface, visible possible to easily anyone adapted cut - prevents rain.

  Next, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view when the waterproof material of the present application is rolled up, FIG. 2 shows the configuration of the waterproof material of the present application, (a) is a double-sided waterproof material, (b) is a single-sided waterproof material, and FIG. 4A is a non-friction surface, FIG. 4 is an enlarged cross-sectional view showing a fine convex surface formed on the back surface of the substrate, and FIG. It is a perspective view which shows the back, (a) is an Example and (b) is a comparative example.

  In the figure, 1 is a waterproof material of the present application, and 2 is a base material. A waterproof adhesive layer 3 is formed on the surface of the substrate 2, and a release paper (not limited to paper) 4 is temporarily attached to the outer surface of the waterproof adhesive layer 3. The back surface of the substrate 2 is subjected to (printing), for example, a design (for example, a lattice pattern) 5 that changes so as to be thin by pressing friction.

  The waterproof material 1 of the present application is wound around a core tube (paper tube) 6 in a roll shape so that the release paper 4 side is on the outside, and the roll is rewound while peeling the release paper 4 so that the waterproof adhesive layer 3 is attached to the surface ( It can be pasted on the waterproof construction surface. Although not shown, the waterproof material 1 of the present application is not limited to a roll, but may be made into a plate-like product in advance according to the assumed waterproof construction surface width.

  FIG. 2A shows a double-sided waterproof material in which release papers 4 and 4 are temporarily attached to both surfaces of the waterproof adhesive layer 3. FIG. 2B shows a single-sided waterproof material (same as FIG. 1) formed by temporarily attaching the release paper 4 to the outer surface of the waterproof adhesive layer 3. In the case of the double-sided waterproof material, one (upper side) release paper 4 is left as it is, and the other (lower side) release paper 4 is peeled off and the waterproof adhesive layer 3 adhered to the adherend surface is adhered to the adherend surface. For this reason, since the back surface of the upper release paper is strongly pressed and rubbed, the design 5 which is changed by pressing friction is also applied to the pressing surface. In the case of FIG. 2A, the base material (core material) 2 embedded in the middle portion of the thickness of the waterproof adhesive layer 3 is perforated, but the perforated base material (core material) is not necessarily provided. Need not be.

  The substrate 2 has a width (H-H 'direction) of 5 to 50 cm and a length (N-N' direction) of 0.5 to 50 m. The width and length are arbitrarily determined depending on the application. Is done. Various materials can be used as the material of the substrate 2 depending on the application. For example, plastic film such as PVC, PE, PET, PP, woven fabric impregnated with asphalt, non-woven fabric, paper, plastic film and woven fabric, non-woven fabric, paper bonded together, or aluminum, copper, iron, etc. There is a single metal foil or a composite product of these.

  The waterproof adhesive layer 3 is composed of an elastomer (for example, butyl rubber, acrylic, natural rubber, isoprene rubber, styrene butadiene rubber, styrene / butadiene block copolymer system, polyisobutylene, silicone rubber) as a main component. , Polyvinyl isobutyl ether type, chloroprene rubber type, nitrile rubber type, graft rubber type, recycled rubber type, or mixed system thereof, mixed system of these with asphalt), tackifier, softener, anti-aging agent, filler An appropriate amount of a crosslinking agent may be added.

  Examples of the tackifier include rosin, rosin derivative, terpene, styrene, petroleum, xylene, phenol, coumarone and indene. Examples of the softener include liquid propene, naphthenic oil, process oil, liquid isoprene, DOP, DBP and the like. Furthermore, examples of the anti-aging agent include aromatic amine derivatives, phenol derivatives, and organic thioates. Furthermore, examples of the filler include zinc white, titanium white, calcium carbonate, clay, pigment, and carbon. Furthermore, as said crosslinking agent, there exist a tyrium system, a resin system, an isocyanate system, an epoxy system, a metal chelate system, etc.

  The design 5 applied to the back surface of the base material 2 (the outer surface of the surface material if it is a single-sided waterproof material, or the outer surface of a release paper temporarily attached to one of the waterproof adhesive layers if it is a double-sided waterproof material) Although a pattern is shown, it may be another pattern, for example, a single color such as red or yellow, or a combination of characters and symbols. Here, the characters include kanji, hiragana, katakana, and english characters, and the content of the expression may or may not be meaningful. The pattern may be a still life or a picture of an animal, a geometrical pattern, a striped pattern, or other (eg, multiple colors = color-coded pattern).

  As long as the design 5 is changed by pressing friction, the design 5 includes not only the thinning or disappearing but also the case where the color changes so as to become dark. For example, when a white pattern is applied to a black background, the black background appears dark when the pattern is thinned by pressing friction. In addition, the microcapsule may be crushed due to pressing friction, and the ink filled in the capsule may flow out and become darker, or may change so that characters, symbols, and pictures such as “OK” appear.

  When applying the design 5 to the substrate 2 or the back side of the release paper, if a chlorinated PP paint or EVA paint that is incompatible with the PET film constituting the substrate 2 is used, the frictional part becomes thin due to strong pressing friction. It becomes easy to change so as to disappear.

  In addition, if the coating material to which the design 5 is applied is a material in which a filler (talc, slaked lime, etc.) or a pigment is increased with respect to the resin, a large amount of filler or pigment is exposed on the design surface. Becomes easy to peel off.

  Furthermore, if the fine convex surface (or fine embossing) 7 is formed in advance on the back surface of the base material 2 as shown in FIG. 4 and the design 5 including the fine convex surface is applied, the design surface is subjected to pressure friction. Changes such as peeling off at the top 7 'are likely to occur.

  When strong pressing friction is applied to the back surface of the base material 2 or release paper 4 on which the design 5 has been applied, for example, with a gloved hand, the normal design 5 is in the state shown in FIG. The friction part changes from the grid pattern of FIG. 3B to the state of FIG. That is, when the change of the design 5 on the back surface of the base material 2 or the release paper 4 is observed, a strong pressing friction is applied to the back surface of the base material 2 or the release paper 4, so that the waterproof adhesive layer 3 is attached. Anyone can easily visually recognize that they are in close contact with the surface.

Next, examples and comparative examples will be described.
Now, a design (lattice pattern) is printed (applied) on one side (the back side) of the substrate 2 made of a PET film using a chlorine-based PP paint that is incompatible with the PET film, and the other side of the film A waterproof adhesive layer 3 having an adhesive force obtained by mixing asphalt with a butyl rubber-based elastomer is formed on the (surface), and the waterproof material 1 of the present application is obtained by temporarily attaching a release paper 4 to the outer surface of the waterproof adhesive layer 3. After cutting this into a width of 100 mm and a length of 20 m, it was wound around a core tube (diameter 80 mm) in a roll shape so that the release paper side was outside.
〔Example〕

As shown in FIG. 5A, a sash frame 8 in which the waterproof material 1 of the present application wound in a roll shape is peeled off the release paper 4 from the tip and the exposed waterproof adhesive layer 3 is fitted in the opening of the outer wall of the building. Affixed to the adherend surface (waterproof construction surface) straddling the seam of the wall 9 and cut when the required length is reached, then the back surface of the base material 2 is strongly pressed and rubbed to form the waterproof adhesive layer 3 Adhered to the adherend surface. In this case, the design (lattice pattern) applied to the back surface of the base material 2 was changed so as to be thin (the state of change is indicated by a broken line). Thus, the waterproofing material 1 is applied in the horizontal direction so as to hide the upper ends of the waterproofing material 1 applied in the vertical direction, and pressed strongly until the design (lattice pattern) applied to the back surface of the base material 2 changes thinly. Rubbed. Prior to these operations, on the lower wall of the sash frame 8, a waterproof sheet (advanced sheet) 10 having a recessed portion that can be fitted to the lower edge of the frame is provided on the upper edge.
[Comparative example]

  As shown in FIG. 5B, a sash frame 8 in which the waterproof sheet 1 of the present application wound in a roll shape is peeled off the release paper 4 from the tip and the exposed waterproof adhesive layer 3 is fitted in the opening of the outer wall of the building as shown in FIG. Affixed to the adherend surface (waterproof construction surface) straddling the seam between the wall 9 and the cut surface when it reaches the required length, and then the waterproof adhesive layer 3 is applied to the back surface of the base material 2 with a slight stroke. Adhered to the adherend surface. In this case, no change was observed in the design (lattice pattern) 5 applied to the back surface of the substrate 2. The lattice pattern is shown as a solid line to show the unchanging situation. Thus, the tape 1 was applied in the horizontal direction so as to hide the respective upper ends of the waterproof material 1 applied in the vertical direction so that the back surface of the base material 2 was lightly boiled. Prior to these operations, on the lower wall of the sash frame 8, a waterproof sheet 10 provided with a recess that can be fitted to the lower edge of the frame is attached to the upper edge.

  After the above operation, the waterproof construction surface of the above examples and comparative examples passed whether or not the waterproof material 1 of the present application was peeled outdoors, but in the above examples, it was not peeled off at all, but in the above comparative examples, the pressing force was weak. Therefore, on the third day, it was confirmed that it was peeled off from the adherend surface.

  From the above results, when the back surface of the substrate 2 is strongly pressed and rubbed to such an extent that the design 5 applied to the back surface becomes thin, the waterproof adhesive layer 3 is securely adhered to the adherend surface (waterproof construction surface). It turns out that it improves the wearing power. On the other hand, it was found that the back surface of the substrate 2 was easily peeled to the extent that the waterproof adhesive layer 3 was adhered to the waterproof construction surface by gently stroking the back surface. In other words, it was found that if the design 5 applied to the back surface of the substrate 2 can be visually recognized, the waterproof adhesive layer 3 adheres to the adherend surface and has a high adhesive force, and thus high waterproofness.

  The waterproof material of the present application can be widely used in the field of waterproofing work on roofs between roofing materials such as roof tiles, slate and metal, and field boards, or waterproofing work around openings such as windows on outer walls. The possibility is high.

It is a perspective view at the time of winding this application waterproof material in roll shape. The structure of this application waterproof material is shown, (a) is a double-sided tape, (b) is a single-sided tape. The back surface of the base material of the waterproof material of the present application is shown, (a) is a non-friction surface, and (b) is after pressing friction.
