Description

DOUBLE LAYER'S WATERPROOF SHEET HAVING A BLANK THAT IS REINFORCED BY RELEASE SHEET OR PRESS SENSITIVE ADHESIVE SHEET AT WIDTHS EDGE OF IT}

The present invention relates to a double-layer waterproof sheet reinforced with a release sheet or an adhesive sheet in the margin (single layer) formed at the width edge of the double-layer waterproof sheet, and more specifically, the surface of the polyurethane sheet or EVA sheet recycled from urethane foam In a multi-layer waterproof sheet laminated with a waterproof adhesive layer made of a protective layer, rubberized asphalt and other waterproof adhesive compositions, a release sheet is formed on the margin formed at the edge of the width (either the surface protective layer or the waterproof adhesive layer formed of a single layer only). Or it relates to a multilayer waterproof sheet reinforced with an adhesive sheet.

Originally, the structure of the multilayer waterproof sheet at the initial stage of developing and using the multilayer waterproof sheet is the surface protective layer A1 as shown in FIG. 1A where the widths of both sides of the surface protective layer and the waterproof adhesive layer are laminated so that no margin is formed. The conventional waterproof method using such a multilayer waterproof sheet as a multilayer waterproof sheet (A) laminated with a waterproof adhesive layer (A2) of the first multilayer waterproof sheet (1A) to the wall (A3) of the structure as shown in Figure 1b While adhesively bonding one side, the waterproof adhesive layer (A2) of the multi-layer waterproof sheet (A) is closely adhered to the bottom (A4) of the structure and then on the other surface protective layer (A1) of the multilayer waterproof sheet (1A) A part of the right waterproof adhesive layer (A2) of the double layer waterproof sheet (2A) of 2 is overlapped and laminated, and the same method is repeated and connected to the multilayer waterproof sheets (A) of 3A and 4A, and the last double layer in the film waterproofing finishing step. Find the other end of the waterproof sheet (A) Because the cutting adhered to the wall to contact the adhesive and at the same time water resistant adhesive layer (A2) bonded to the bottom so as to be in close contact with the water wall (A3) is standing in the film-forming operation of the multi-layer water resistant sheet to be completed.

The waterproofing method obtained by the construction shown in FIG. 1B by using the multilayer waterproof sheet A shown in FIG. 1A is not connected to the waterproof adhesive layers A2 first to form an integrated full-layer coating layer of the waterproof adhesive layers A2. In the joint, the waterproof adhesive layer is bonded between the surface protective layer (A1) and the surface protective layer (A1), but first, the adhesive state is poor due to the original strength caused by the stiffness of the surface protective layer. In addition, if the surface layer is formed by forming a full-layer coating film with a film-coated waterproof sheet or forming a surface layer with roller mortar on it, there may be a crushing phenomenon that occurs during work such as impact or shear force generated during pouring, and the surface layer may be a synthetic resin coating film. Formed with polyurethane resin, epoxy resin, etc. to complete waterproofing, and various types of fillings generated in the surface layer during use , By a developer to easily advance in a large waterproof adhesive tack adhesive to the inner surface heterogeneity by interlayer shearing force or the like occurs thereby deteriorating the adhesion.

In order to solve the above problems and at the same time to request a more effective waterproofing method, various forms of double-layered waterproof sheets have been formed, and introducing such double-layered waterproof sheets has a structure as shown in FIGS. 2A to 2E.

2A is a multilayer waterproof sheet 2A in which a surface protective layer 2A1 and a waterproof adhesive layer 2A2 are laminated, and a multilayer waterproof sheet 2A having a margin portion 2A3 formed at the right edge of the surface protective layer 2A1. 2B is a multilayer waterproof sheet 2B laminated with a surface protective layer 2B1 and a waterproof adhesive layer 2B2, and a multilayer waterproof sheet 2B having a margin portion 2B3 formed at the left edge of the surface protective layer 2B1. FIG. 2C is a multilayer waterproof sheet 2C laminated with a surface protective layer 2C1 and a waterproof adhesive layer 2C2, and a plurality of waterproof layers having margins 2C1 'and 2C2' formed on the left surface protective layer and the right waterproof adhesive layer, respectively. Sheet.

In addition, 2d is a multilayer waterproof sheet 2D laminated with a surface protective layer 2D1 and a waterproof adhesive layer 2D2, and a plurality of blank portions 2D1 'and 2D2' are formed on the right surface protective layer and the left waterproof adhesive layer, respectively. Waterproof sheet.

FIG. 2E is a multilayer waterproof sheet 2E laminated with the surface protective layer 2E1 and the waterproof adhesive layer 2E2, and the multilayer waterproof sheet having margins 2E1 'and 2E1 " formed on the left and right lower surfaces of the surface protective layer 2E1. 1F is a multilayer waterproof sheet 2F laminated with a surface protective layer 2F1 and a waterproof adhesive layer 2F2, and the margins 2F2 'and (2F2 ") on the upper and left sides of the waterproof adhesive layer 2F2. Is formed waterproof sheet.

As described above, the multilayered waterproof sheet having various forms of the margin shows excellent waterproof function in performing the waterproofing method, but the conventional double-layered sheet of double-layered waterproof sheet or release paper using the conventional thin film release film or release paper and the release process by other methods are double-layered. As a result of severe deformation during storage and transportation of the waterproof sheet, a bad waterproof sheet is generated, making it difficult to construct and further reducing the waterproof function.

The present invention relates to a release treatment structure of a double layer waterproof sheet formed with a margin part and to match a release sheet or adhesive sheet having a supporting force in the margin part to reduce the defect rate generated during the storage and transportation process of the double layer waterproof sheet. It is an object of the present invention to provide a multi-layer waterproof sheet reinforced with release paper in the margin where it can be increased and further excellent water resistance.

Regardless of a conventional multilayer waterproof sheet, that is, a multilayer waterproof sheet without a margin or a multilayer waterproof sheet having a margin portion, a release film or a release paper is attached to a portion exposed to the waterproof adhesive layer and the adhesive surface, and then packaged in roll units.

Here, the double layer waterproof sheet without margin is not a problem, but among the double layer waterproof sheet formed with the margin, among the double layer waterproof sheet in which the waterproof adhesive layer of the double layer waterproof sheet protrudes more than the surface protection layer in the width direction, many deformations occur during the storage and transportation process. In addition, the workability is poor and even the waterproof function is inferior at the end.

The present invention is a multi-layer waterproof sheet which solves the problems of the conventional double-layer waterproof sheet having a margin as described above. It is related to a double layer waterproof sheet reinforced with a release sheet or adhesive sheet at the edge (margin) of width to prevent the deformation of the edge of the product and to maintain the excellent waterproof function by waterproof construction without affecting the construction. 3A shows a release sheet 3A4 or a release sheet having a release surface 3A4 'at a margin of a multilayer waterproof sheet 3A having a margin portion 3A1' formed at one side of the surface protective layer 3A1. It is made by bonding the release sheet 3A4 laminated with the surface 3A4 'and the corrugated wrinkled paper 3A4 ", and the thin film of release paper or the release film 3A3 adhered on the waterproof adhesive layer. In FIG. 3B, the margins 3B1 'and 3B2' are formed on the surface protection layer 3B1 on the other side and on the waterproof adhesive layer 3B2 on the right side, respectively, to form a release surface 3B4 'on the margin. A double layer having a release sheet 3B4 or a release surface 3B4 'and a release sheet 3B4 laminated with corrugated wrinkled paper 3B4 "to be matched, and a separate thin film release paper or release film 3B3 attached to the waterproof adhesive layer. It is a waterproof sheet 3B.

3C shows a release sheet 3C4 or a release surface 3C4 'having margin portions 3C1' and (3C1 ") formed on both sides of the surface protective layer 3C1 and having a release surface 3C4 'on the margin. And a release sheet (3C4) laminated with a corrugated wrinkle sheet (3C4 "), and a waterproof adhesive layer (3C2) is a multilayer waterproof sheet (3C) to which a thin film release film or a release paper (3C3) is attached, and FIG. 3D is a waterproof adhesive layer (3D2). Margins (3D2 ') and (3D2 ") are formed on both sides, and a release sheet (3D4) or a release surface (3D4') and a corrugated wrinkle paper (3D4") having a release surface (3D4 ') are laminated on the margin. The release sheet 3D4 is attached to each other and is a multilayer waterproof sheet 3D on which a thin film release paper or a film 3D3 is laminated on the waterproof adhesive layer 3D2.

As described above, in order to efficiently waterproof, a multilayer waterproof sheet having various forms of margins is required. Here, the structure of the multilayer waterproof sheet having margins as shown in FIGS. 2A, 2B, 2C, 2E, and 2F is rolled. The surface protective layer (urethane foam regenerated polyurethane sheet) with large bearing capacity in the wound state is hardly curled or collapsed even without thick release sheet or release paper sheet with corrugated wrinkles. In the case of the surface protective layer of the EVA sheet, the edges are frequently bent or collapsed.

Furthermore, the structure of the double layer waterproof sheet in which the waterproof adhesive layer made of rubberized asphalt or other waterproof adhesive composition protrudes to the edge of the width as shown in FIGS. 2D and 2F is stored in a rolled state because the waterproof adhesive layer has a weak supporting force. Without the supportive release sheet during transportation and use, the waterproof adhesive layer cannot be maintained in its original state and is deformed to be unusable.

Therefore, the above-mentioned release sheet is needed to protect the waterproof adhesive layer, that is, the circular state of the double-layer waterproof sheet, and to prevent the work by the contamination of the margin part in the future use, and this sheet is composed of thick white paper or cardboard having a release surface and A release sheet having a corrugated corrugated sheet having a surface and a low foam sheet having a predetermined thickness having a release surface and having a release surface may be used.

In addition, in the margin of the surface protection layer, it is possible to replace the adhesive surface coated with the adhesive instead of the release surface in the configuration of the release sheet as described above.

The present invention requires a multi-layered waterproof sheet having various types of margins in order to effectively construct the joints of the multi-layered waterproof sheet in performing waterproofing of the coating film with a multi-layered waterproof sheet. Or defects caused by circular deformation in storage, transportation, and work sites by reinforcing the margins of the edges of the double-layer waterproof sheet used in the roll state by attaching a release sheet or adhesive sheet having an adhesive surface consistent with the margins. It can be a double layer waterproof sheet reinforced with a release sheet or an adhesive sheet in the margin of the margin of the width that can smooth the waterproofing work and can expect excellent waterproofing effect.
