Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically to a puncture-proof, seepage-proof composite waterproof membrane. Background Technology

[0002] Waterproof membrane is a rollable sheet-like waterproof material with features such as waterproofing, flexibility, and durability. It is mainly made of materials such as asphalt and polymers, and is widely used in construction engineering, tunnel and underground engineering, water conservancy projects, and other fields. It can effectively prevent water penetration and protect structures from water erosion.

[0003] The existing publication number CN217838798U discloses a composite waterproof membrane, including a membrane body with a layered structure. The membrane body includes a polymer material layer, a first adhesive reinforcement layer, a base layer, a second adhesive reinforcement layer, and a release liner. The first adhesive reinforcement layer is connected between the base layer and the polymer material layer. The second adhesive reinforcement layer is disposed on the side of the base layer facing away from the first adhesive reinforcement layer. The release liner is disposed on the side of the second adhesive reinforcement layer facing away from the base layer. The composite waterproof membrane provided by this application has a second adhesive reinforcement layer with high adhesion, enabling better adhesion between the polymer material layer and the substrate. It also possesses the advantages of large area and convenient and quick construction characteristics of polymer waterproof membranes.

[0004] However, if the above-mentioned composite waterproof membrane encounters sharp objects during use and transportation, the sharp objects can easily puncture the composite waterproof membrane, causing the membrane to fail to waterproof properly and reducing its service life. Therefore, we have proposed a puncture-resistant and seepage-proof composite waterproof membrane. Utility Model Content

[0005] The purpose of this utility model is to provide a puncture-resistant, seepage-proof composite waterproof membrane to solve the problem mentioned in the background art: if existing composite waterproof membranes encounter sharp objects during use and transportation, the sharp objects can easily puncture and break through the composite waterproof membrane, thus preventing the membrane from waterproofing properly and reducing its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a puncture-proof and seepage-proof composite waterproof membrane, comprising a base layer, wherein the top and bottom of the base layer are provided with reinforcing layers, and a surface layer and an adhesive layer are respectively provided above the upper reinforcing layer and at the bottom of the lower reinforcing layer;

[0007] A repair layer is provided between the top of the upper reinforcing layer and the bottom of the surface layer.

[0024] As a further description of the above technical solution:

[0025] The capsule is made of thermoplastic polyurethane, and the self-sealing liquid is made of butyl rubber liquid.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. This puncture-resistant, seepage-proof composite waterproof membrane uses a plastic-coated steel wire mesh embedded in the surface layer to block sharp objects from penetrating the surface, preventing them from further penetrating the interior. Simultaneously, the reinforcing layer, made of fiberglass cloth, utilizes its high tensile strength and the interlocking of fibers to prevent sharp objects from piercing it. Combined with the plastic-coated steel wire mesh, this prevents sharp objects from directly puncturing the waterproof membrane, thus improving the overall strength of the waterproof membrane and preventing punctures by sharp objects.

[0028] 2. This puncture-resistant, seepage-proof composite waterproof membrane features a repair layer. When the surface layer is punctured, a sharp object enters the storage hole and punctures the membrane, releasing the self-sealing liquid inside. The self-sealing liquid then seals the puncture hole, repairing the damage. This mechanism effectively seals and repairs punctures when the surface of the waterproof membrane is punctured, preventing any impact on subsequent waterproofing and thus extending its service life.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] This utility model provides a puncture-resistant, seepage-proof composite waterproof membrane that improves the overall strength of the waterproof membrane, thus preventing punctures by sharp objects. It can seal and repair punctures at 400mm on the surface of the waterproof membrane, preventing any impact on subsequent waterproofing and extending its service life. Please refer to [link / reference]. Figure 1-4 Including the base layer 100;

[0038] Please refer to it again. Figure 1 , Figure 2 and Figure 4The base layer 100 has reinforcing layers 200 at its top and bottom, which enhance the overall strength of the waterproof membrane. Above the upper reinforcing layer 200 and at the bottom of the lower reinforcing layer 200, there are surface layers 400 and adhesive layers 500, respectively. The surface layer 400 is used for waterproofing, and the adhesive layer 500 is used for connection to the installation location. The base layer 100 is made of polyester fiber, which has high tensile strength and can withstand significant external forces without easily breaking. This allows the waterproof membrane to effectively resist deformation and cracking of the base layer during construction and use, ensuring the stability of the waterproofing effect and providing good durability. It possesses both corrosiveness and a certain degree of flexibility. The reinforcing layer 200 is made of fiberglass cloth. Fiberglass cloth is a mesh structure formed by numerous glass fibers through weaving and other processes. When a sharp object attempts to pierce the cloth, it first encounters the obstruction of the first layer of fibers. The sharp object needs to overcome the tensile strength of these fibers to break or displace them before it can penetrate further. However, fiberglass cloth is not just a single layer of fibers, but rather composed of multiple interwoven layers. Each time the sharp object penetrates a layer of fibers, it must repeatedly overcome similar resistance. As the number of layers penetrated increases, the required piercing force also accumulates, thus effectively hindering the sharp object. At the same time, the fibers interact with each other... The interweaving and restraint further prevent the entry of sharp objects, while also assisting the base layer 100 in enhancing overall strength. The bottom of the surface layer 400 is inlaid with a plastic-coated steel wire mesh 410, which serves to block further entry of sharp objects, thereby reducing pressure on the reinforcing layer 200. It also possesses flexibility, making it easier to bend and adhere to the waterproof membrane. The surface layer 400 is made of elastomeric modified bitumen, which has excellent flexibility, good crack resistance, and outstanding weather resistance. The adhesive layer 500 is made of self-adhesive rubber bitumen, which has good adhesion properties and can tightly adhere to various base layers. Effectively preventing water penetration and facilitating construction, the bottom of the adhesive layer 500 is bonded with release paper 510. Release paper 510 is used to prevent the adhesive layer 500 from bonding with other objects before construction, thus facilitating the rolling up of the waterproof membrane for easy transportation. When a sharp object pierces the surface layer 400, it comes into contact with the plastic-coated steel wire mesh 410. The plastic-coated steel wire mesh 410 blocks the sharp object through its own mesh holes, preventing it from further penetrating into the membrane. At the same time, the reinforcing layer 200 blocks the sharp object to prevent it from puncturing the waterproof membrane. With the assistance of the plastic-coated steel wire mesh 410, the pressure on the reinforcing layer 200 is reduced, improving the puncture resistance.

[0039] In summary, this can improve the overall strength of the waterproof membrane, thereby preventing it from being punctured by sharp objects.

[0040] Please refer to it again. Figure 1-4A repair layer 300 is provided between the top of the upper reinforcing layer 200 and the bottom of the surface layer 400. The repair layer 300 is used to repair the puncture site in conjunction with the capsule 320. The repair layer 300 is made of polypropylene fibers. The mesh structure formed by the interwoven polypropylene fibers provides support for the entire system. Even after the puncture is made and the self-sealing liquid 321 is placed, the overall structural stability can still be maintained. At the same time, it has high strength and toughness, which can enhance the strength of the entire composite material. The top of the repair layer 300 has uniformly opened storage holes 310 for placing the capsule 320. The inner cavity of the storage hole 310 contains the capsule 320, which is used to hold the self-sealing liquid 321. The inner cavity of the capsule 320 is filled with the self-sealing liquid 321, which is used to repair the puncture site. The body 320 is made of thermoplastic polyurethane, which has high strength and wear resistance, and can effectively resist friction and compression in daily use without easily breaking. When punctured by a sharp object, it can break in a relatively controlled manner, ensuring that the self-sealing liquid 321 is accurately released to the damaged area. The self-sealing liquid 321 is made of butyl rubber adhesive, which has good airtightness, chemical corrosion resistance and flexibility, making it suitable as the main component of the self-sealing liquid 321 to fill the punctured area, achieve sealing and repair. When a sharp object punctures the surface layer 400 and enters the repair layer 300, the sharp object punctures the capsule 320 in the storage hole 310, and the capsule 320 releases the self-sealing liquid 321 from the puncture opening. The self-sealing liquid 321 then seals and repairs the puncture.

[0041] In summary, this technology can seal and repair punctures in the surface of waterproof membrane at a depth of 400 mm, preventing any impact on subsequent waterproofing and thus extending its service life.

[0042] In practical use, when a sharp object pierces the surface layer 400, it comes into contact with the plastic-coated steel wire mesh 410. The plastic-coated steel wire mesh 410 blocks the sharp object through its mesh openings, preventing it from further penetrating the roll material. At the same time, the reinforcing layer 200 also blocks the sharp object to prevent it from puncturing the waterproof roll material. With the assistance of the plastic-coated steel wire mesh 410, the pressure on the reinforcing layer 200 is reduced. When the sharp object enters the repair layer 300, it punctures the capsule 320 in the storage hole 310. The capsule 320 then releases self-sealing liquid 321 from the puncture opening, which then seals and repairs the puncture.
