Abstract
Description
Technical Field
[0001] The utility model relates to the field of waterproof coiled materials, in particular to a puncture-resistant waterproof coiled material. Background Art
[0002] With the development of cities, the green area of cities has been greatly reduced, and greening buildings and ecological buildings have been put on the important development agenda. Traditional waterproof membranes mostly use asphalt as the main waterproof layer, which usually has a waterproof effect, but cannot resist the puncture of plant roots; when the waterproof layer of the waterproof membrane is punctured by plant roots, its waterproof effect will be greatly reduced or even fail, eventually leading to the risk of leakage.
[0003] Chinese utility model patent CN211227003U discloses a root-penetration-resistant waterproof membrane, which belongs to the field of building waterproof materials. The key points of its technical solution are that it includes a base cloth and a waterproof root-resistant layer for making the waterproof membrane, the waterproof root-resistant layer is coated on the base cloth, and an adhesive layer is provided on the side of the base cloth away from the waterproof root-resistant layer. A card slot with a top opening is provided on the side of the waterproof membrane, and a card block is carded in the card slot. The card block is fixedly connected to the adjacent waterproof membrane, and the top surface of the card block is bonded with an anti-seepage layer covering the joints of the waterproof membrane, so as to achieve the effect of reducing water leakage at the joints of the waterproof membrane.
[0004] In the above-mentioned comparative documents, the problem of curling of the waterproof membrane is reduced by setting the card slots and the card blocks so that the card slots and the card blocks are connected to each other. However, in actual use, due to the long length of the waterproof membrane, when laying the waterproof membrane, if the waterproof membrane is laid by connecting adjacent membranes, it is not only cumbersome, but also the design of the card slots and the card blocks makes the waterproof membrane in the process of transportation or storage. Once the waterproof membrane is placed vertically, the card slots and card blocks of the waterproof membrane will be squeezed, resulting in curling, which is not conducive to the later laying of the waterproof membrane.
[0005] Therefore, it is necessary to provide a puncture-resistant waterproof membrane to solve the above technical problems. Utility Model Content
[0006] The purpose of the utility model is to provide a puncture-resistant waterproof membrane to solve the problem that the prior art proposed in the above-mentioned background technology has a long length of the waterproof membrane. When laying the waterproof membrane, if the waterproof membrane is laid by clamping adjacent membranes, it is not only cumbersome, but also the design of the clamping groove and the clamping block makes it so that when the waterproof membrane is transported or stored, once the waterproof membrane is placed vertically, the clamping groove and the clamping block of the waterproof membrane will be squeezed, resulting in curling, which is not conducive to the later laying of the waterproof membrane.
[0007] Based on the above ideas, the utility model provides the following technical solutions: including a protective layer, a covering protective layer is integrally formed on one side of the protective layer, the lower surface of the covering protective layer and the upper surface of the protective layer are located on the same horizontal plane, and a groove is formed on the other side of the protective layer; a second adhesive layer is provided on the lower surface of the covering protective layer, and a first adhesive layer adhered to the second adhesive layer is provided in the groove, and the second adhesive layer and the first adhesive layer are both quadrilateral structures.
[0008] As a further solution of the utility model: an anti-deformation layer is adhered to the bottom of the covering protective layer for supporting the covering protective layer, and a second tearable film is adhered to a side of the anti-deformation layer away from the covering protective layer.
[0009] As a further solution of the utility model: a waterproof and root-resistant layer is adhered to the bottom of the protective layer, and a fourth adhesive layer is coated on the bottom of the waterproof and root-resistant layer.
[0010] As a further solution of the utility model: a tire base cloth is provided at the bottom of the fourth viscose layer.
[0011] As a further solution of the utility model: a third adhesive layer is adhered to the bottom of the tire base fabric, and the second tearable film is adhered to the lower surface of the third adhesive layer.
[0012] As a further solution of the utility model: a first tearable film is adhered to the surface of the first adhesive layer.
[0013] As a further solution of the utility model: the fourth adhesive layer is a fourth adhesive layer formed by polyvinyl alcohol environmentally friendly adhesive.
[0014] Compared with the prior art, the utility model has the beneficial effect that the second adhesive layer and the first adhesive layer are both quadrilateral structures. The design of the quadrilateral structure makes the connection between the second adhesive layer and the first adhesive layer more stable. The second adhesive layer covering the lower surface of the protective layer is adhered to the waterproof membrane that has been laid, so that the second adhesive layer and the first adhesive layer on one side are adhered to each other. The structure is simple and the operation is convenient. It can not only prevent the edges between the two waterproof membranes from curling at the same time, but also use the second adhesive layer to cover the edge position of another waterproof membrane, thereby reducing the amount of exposed edges of the waterproof membrane and preventing leakage at the edges of the waterproof membrane.
[0015] Compared with the prior art, the beneficial effect of the utility model is that the anti-deformation layer can prevent the waterproof membrane from being placed vertically during transportation or storage in order to save space, causing the covering protective layer to be deformed, making it easy for the waterproof membrane to curl when laid. At the same time, the sum of the thickness of the anti-deformation layer and the covering protective layer is greater than the thickness of the waterproof membrane, so that the diameter of the lower section of the waterproof membrane after rolling up is greater than the diameter of the upper section, thereby facilitating the vertical placement of the membrane without tipping over.

[0023] During the specific operation, when laying the puncture-resistant waterproof coiled material, tear off the second tearable film 7 and lay the waterproof coiled material at the position that needs waterproofing. The waterproof coiled material with grooves 3 formed on both sides of the protective layer 1 can be selected and laid to the middle position, and the first adhesive layer 4 is arranged in the grooves 3 on both sides, and the first tearable film 5 is adhered to the first adhesive layer 4. The first tearable film 5 on one side is torn off, and then another waterproof coiled material is selected. A puncture-resistant waterproof coiled material comprises a protective layer 1, one side of the protective layer 1 is integrally formed with a covering protective layer 2, the lower surface of the covering protective layer 2 and the upper surface of the protective layer 1 are located on the same horizontal plane, and a groove 3 is formed on the other side of the protective layer 1; the lower surface of the covering protective layer 2 is provided with a second adhesive layer 8, and the groove 3 is provided in the groove 3. A first adhesive layer 4 adhered to the second adhesive layer 8 is provided, and a first tearable film 5 is adhered to the surface of the first adhesive layer 4; the second adhesive layer 8 and the first adhesive layer 4 are both quadrilateral structures. The design of the quadrilateral structure makes the connection between the second adhesive layer 8 and the first adhesive layer 4 more stable, and the second adhesive layer 8 covering the lower surface of the protective layer 2 is adhered to the waterproof membrane that has been laid, so that the second adhesive layer 8 and the first adhesive layer 4 on one side are adhered to each other. The structure is simple and the operation is convenient. It can not only prevent the edges between the two waterproof membranes from curling at the same time, but also use the second adhesive layer 8 to cover the edge position of another waterproof membrane, reduce the amount of exposed edges of the waterproof membrane, and prevent leakage at the edges of the waterproof membrane.
