Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically to a self-adhesive bitumen waterproof membrane for roofing. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up and serve as a leak-proof connection between the foundation and the building. They are the first line of defense for waterproofing the entire project and play a vital role in the overall project.

[0003] Chinese Patent No. CN222039872U discloses a high-strength, high-elongation, non-woven self-adhesive bitumen waterproof membrane, which possesses both high tensile strength and high elongation, and is not afraid of sunlight. To achieve the above objectives, the present invention provides a high-strength, high-elongation, non-woven self-adhesive bitumen waterproof membrane, comprising: a polyester film layer, a bitumen adhesive layer, and a base film layer arranged sequentially from top to bottom. The polyester film layer can block light, thereby preventing the bitumen adhesive layer from aging.

[0004] However, in the above-mentioned technical solutions, the existing waterproof membrane usually has a release membrane at the overlapping position to reduce external dust and impurities. This membrane is removed after the waterproof membrane is laid, thereby reducing cleaning steps by cooperating with the overlapping position of the adjacent waterproof membrane. However, workers need to remove the release membrane at the overlapping position of the waterproof membrane additionally, and after its removal, external dust falling on its surface will reduce the adhesion performance. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a self-adhesive bitumen waterproof membrane for roofing.

[0006] The technical solution of this utility model is as follows: A self-adhesive bitumen waterproof membrane for roofing includes a membrane body connected to a winding drum. The membrane body consists of a heat insulation layer, a bitumen layer, an adhesive layer, and a first isolation layer, with the first isolation layer at the bottom and the others arranged sequentially from bottom to top. An overlap layer is connected to the heat insulation layer. A linkage component is connected to the heat insulation layer, and the linkage component includes an isolation edge membrane and a pressure-sensitive adhesive layer. The isolation edge membrane is bonded to the overlap layer, and the pressure-sensitive adhesive layer is disposed between the overlap layer and the isolation edge membrane, and is connected to the isolation edge membrane. In use, the pressure-sensitive adhesive on the isolation edge membrane adheres to the first isolation layer on the adjacent membrane body, and the first isolation layer causes the isolation edge membrane to move away from the overlap layer.

[0007] Preferably, a waterproof layer is connected between the asphalt layer and the insulation layer.

[0008] Preferably, a non-woven fabric layer is connected between the adhesive layer and the asphalt layer.

[0009] Preferably, both ends of the first isolation layer are connected to tear strips.

[0010] Preferably, the insulation layer is made of aluminum foil, and a polyurethane layer is attached to the insulation layer.

[0011] Preferably, the insulation layer has multiple evenly distributed anti-slip strips connected to it.

[0012] Preferably, the width of the pressure-sensitive adhesive layer is smaller than the width of the isolation edge film.

[0013] Preferably, the overlap width is equal to or greater than 80mm.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] In this invention, during the laying of the roll material, a portion of the release liner on the laid roll material is torn off. The first release layer on the adjacent roll material is torn off and bonded to the roll material to cover its overlap layer. At the same time, the first release layer is bonded to the pressure-sensitive adhesive layer in the linkage component. The bonding between the two will cause the release liner to move synchronously through the pressure-sensitive adhesive layer when the first release layer is pulled. The release liner moves away from the overlap layer, making it easier for the adjacent roll material to be bonded and fixed to the overlap layer through the adhesive layer. This reduces the amount of labor required for workers to remove the release liner. After the release liner is removed, the overlap layer is exposed to the outside environment for a shorter time, avoiding external contamination that may affect the bonding effect.

[0021] Example 1

[0022] like Figures 1-4As shown, this utility model proposes a self-adhesive bitumen waterproof membrane for roofing, comprising a membrane body 1, a take-up cylinder 2, an overlap layer 7, and a linkage assembly. The membrane body 1 is connected to the take-up cylinder 2 and consists of a heat insulation layer 3, a bitumen layer 4, an adhesive layer 5, and a first isolation layer 6. The first isolation layer 6 is located at the bottom, and the others are arranged sequentially from bottom to top. The overlap layer 7 is connected to the heat insulation layer 3. The linkage assembly is connected to the heat insulation layer 3 and includes an isolation edge membrane 8 and a pressure-sensitive adhesive layer 9. The isolation edge membrane 8 is bonded to the overlap layer 7, and the pressure-sensitive adhesive layer 9 is disposed between the overlap layer 7 and the isolation edge membrane 8, and is connected to the isolation edge membrane 8. In use, the pressure-sensitive adhesive on the isolation edge membrane 8 is bonded to the first isolation layer 6 on the adjacent membrane body 1, and the first isolation layer 6 drives the isolation edge membrane 8 to move away from the overlap layer 7.

[0023] In an optional embodiment, the width of the pressure-sensitive adhesive layer 9 is smaller than the width of the isolation edge film 8; the smaller width of the pressure-sensitive adhesive layer 9 reduces cost.

[0024] In an optional embodiment, tear strips 12 are connected to both ends of the first isolation layer 6; the tear strips 12 facilitate the separation of the first isolation layer 6 from the roll body 1 by the workers.

[0025] Example 2

[0027] In an optional embodiment, a waterproof layer 10 is connected between the asphalt layer 4 and the heat insulation layer 3; the waterproof layer 10 is made of non-woven fabric-based roll material, that is, a waterproof roll material made of non-woven fabric.

[0028] In an optional embodiment, a non-woven fabric layer 11 is connected between the adhesive layer 5 and the asphalt layer 4; the addition of a non-woven fabric layer 11 between the asphalt layer 4 and the adhesive layer 5 can specifically improve crack resistance, mechanical strength and durability.

[0029] Example 3

[0030] like Figure 3 As shown, this utility model proposes a self-adhesive bitumen waterproof membrane for roofing. Compared with Embodiment 2, this embodiment describes the detailed structure of the heat insulation layer 3.

[0031] In an optional embodiment, the insulation layer 3 is made of aluminum foil, and a polyurethane layer is attached to the insulation layer 3; the smooth properties of the polyurethane layer can reduce wrinkles when the roll body 1 is laid, and can improve puncture resistance and isolate the external influence on the aluminum foil and asphalt.

[0032] In an optional embodiment, a plurality of evenly distributed anti-slip strips 13 are connected to the heat insulation layer 3; the anti-slip strips 13 are selected from, but are not limited to, rubber layers, and the shape of the anti-slip strips 13 is arc-shaped to reduce the impact on the adhesive layer 5 of the roll body 1 and prevent it from becoming concave and affecting the adhesive effect.

[0033] In an optional embodiment, the width of the overlap layer 7 is equal to or greater than 80 mm.

[0034] In summary, when using this utility model, the worker removes the first release layer 6 from the first roll body 1, and then pulls the first release layer 6 to bond the adhesive layer 5 on the roll body 1 to the roof. After bonding, another roll body 1 is placed on one side of the bonded roll body 1, and a portion of the roll body 1 is brought into contact with the overlap layer 7 of the bonded roll body 1. Then, a portion of the first release layer 6 on the unbonded roll body 1 is torn off and bonded to the roof. At the same time, one end of the release edge film 8 is torn off and its pressure-sensitive adhesive layer 9 is bonded to the first release layer 6. Then, as the worker pulls the first release layer 6, the release edge film 8 is torn off simultaneously to remove it, so that the release edge film 8 on the overlap layer 7 is removed to keep it clean and improve the bonding effect.
