Description

Technical Field

[0001] This utility model relates to the technical field of waterproof membranes, and in particular to flame-retardant and self-extinguishing pre-laid waterproof membranes. Background Technology

[0002] Pre-applied waterproof membranes refer to waterproof membranes on which structural concrete is poured directly. The self-adhesive layer of the membrane bonds well with the concrete, achieving a pre-applied, reverse-adhesive effect. While existing pre-applied waterproof membranes can be used for building waterproofing, traditional waterproof membranes often sacrifice some mechanical properties when prioritizing waterproofing performance. For example, some waterproof membranes with asphalt as the main component rely on the density of asphalt to prevent water penetration. However, asphalt itself has limited mechanical properties and low tensile strength, making it prone to cracking under tensile forces. In such cases, once the waterproof layer cracks due to external forces, water can easily seep into the building structure, leading to waterproofing failure. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flame-retardant, self-extinguishing pre-laid waterproof membrane.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Flame-retardant and self-extinguishing pre-laid waterproof membrane includes a reinforcing layer, a waterproof layer hot-melt bonded to the reinforcing layer, a protective layer hot-pressed onto the waterproof layer, and a self-adhesive layer bonded to the end of the reinforcing layer away from the waterproof layer. The reinforcing layer is a densely textured glass fiber cloth treated with a silane coupling agent, used to enhance the tensile strength, puncture resistance, and dimensional stability of the membrane.

[0006] Preferably, a first isolation protective layer is adhered to the protective layer, and a second isolation protective layer is adhered to the self-adhesive layer.

[0007] Preferably, both the first and second protective layers are made of polyethylene film or release paper material to protect the internal structure of the roll from contamination and damage during storage and transportation.

[0008] Preferably, the protective layer is an aluminum foil layer, which has high reflectivity and can reflect ultraviolet rays and heat, assisting the roll material in achieving flame-retardant and self-extinguishing functions, and improving the weather resistance of the roll material.

[0009] Preferably, the self-adhesive layer is a rubber asphalt self-adhesive layer or a synthetic polymer self-adhesive layer, which can bond tightly to the substrate and ensure the waterproof sealing between the roll material and the substrate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. By combining the reinforcing layer and the waterproof layer, using fiberglass cloth as the reinforcing layer and thermoplastic polyolefin as the waterproof layer, the thermoplastic polyolefin layer possesses good toughness and strength, capable of withstanding a certain degree of tensile and bending mechanical forces. Its molecular structure allows it to disperse stress through molecular chain deformation under load, rather than breaking directly like brittle materials. For example, in roof waterproofing projects, when the roof structure expands or contracts due to temperature changes, the thermoplastic polyolefin layer can expand or contract accordingly without easily breaking. Simultaneously, the fiberglass cloth, as the reinforcing layer, further enhances the mechanical properties of the membrane. Fiberglass has high tensile strength, and its fibrous structure effectively prevents crack propagation. When the membrane is subjected to external tensile forces, the fiberglass cloth can bear most of the tensile force, preventing excessive deformation or breakage of the thermoplastic polyolefin layer. Importantly, the fiberglass cloth is tightly bonded to the thermoplastic polyolefin layer and will not damage the waterproof structure of the layer due to its own presence, thus solving the problem of balancing waterproof performance and mechanical properties in traditional waterproof membranes.

[0012] 2. Through the cooperation of the first and second isolation protective layers, which act as a protective barrier, external contaminants such as moisture and dust can be prevented from entering the interior of the roll material from the upper and lower surfaces. This protects the roll material from external moisture and contaminants during storage and transportation, ensuring the integrity of the internal structure of the roll material.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figures 1 to 5 This flame-retardant, self-extinguishing pre-applied waterproof membrane includes a reinforcing layer 1, a waterproof layer 2 heat-fused to the reinforcing layer 1, a protective layer 3 heat-pressed onto the waterproof layer 2, and a self-adhesive layer 4 bonded to the end of the reinforcing layer 1 away from the waterproof layer 2. This membrane solves traditional problems by utilizing fiberglass cloth in the reinforcing layer 1 and thermoplastic polyolefin in the waterproof layer 2. The thermoplastic polyolefin layer has good toughness and strength, and can disperse stress through molecular chain deformation, allowing it to adapt to temperature expansion and contraction in roofing projects without cracking. The fiberglass cloth, with its high tensile strength, prevents crack propagation, distributes tensile force during stretching, avoids deformation and breakage, and does not damage the waterproof structure. This design overcomes the shortcomings of traditional roll materials, achieving a good balance between waterproofing and mechanical performance. Reinforcing layer 1 is a densely textured glass fiber cloth treated with silane coupling agent, which is used to enhance the tensile strength, puncture resistance and dimensional stability of the roll material. The glass fiber cloth of reinforcing layer 1 significantly improves the tensile strength and puncture resistance of the roll material. During construction and use, even if subjected to external impact, tension or pressure, the roll material can maintain its structural integrity and avoid damage and failure caused by external forces.

[0021] In this embodiment, a first isolation protective layer 5 is attached to the protective layer 3, and a second isolation protective layer 6 is attached to the self-adhesive layer 4. Both the first isolation protective layer 5 and the second isolation protective layer 6 are made of polyethylene film or release paper material, which are used to protect the internal structure of the roll material from contamination and damage during storage and transportation. The protective layer 3 is an aluminum foil layer, which has high reflectivity and can reflect ultraviolet rays and heat, assisting the roll material in achieving flame-retardant and self-extinguishing functions and improving the weather resistance of the roll material. The self-adhesive layer 4 is a rubber asphalt self-adhesive layer or a synthetic polymer self-adhesive layer, which can be tightly bonded to the base layer to ensure the waterproof sealing between the roll material and the base layer.

[0022] The working principle of this embodiment is as follows: First, the upper first protective layer 5 is removed, and the roll material is laid on the pre-treated base layer. Then, the lower second protective layer 6 is removed, allowing the self-adhesive layer 4 to adhere tightly to the base layer. During the laying process, relying on the reinforcing effect of the reinforcing layer 1 and the adhesive effect of the self-adhesive layer 4, the roll material can adapt to various shapes and deformations of the base layer, including complex areas such as corners and pipe roots. The overlapping parts between roll materials are bonded through the self-adhesive layer 4, ensuring that the entire waterproof area forms a continuous and seamless waterproof system. During use, the protective layer 3 and the waterproof layer 2 provide flame-retardant, self-extinguishing, and waterproof functions. The reinforcing layer 1 and the self-adhesive layer 4 ensure the mechanical properties and structural stability of the roll material. The first protective layer 5 and the second protective layer 6, to a certain extent, prevent external factors from damaging the interior of the roll material, thereby ensuring that the roll material can stably perform its waterproof and flame-retardant functions for a long time, providing reliable protection for buildings.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
