Description

Technical Field

[0001] This invention relates to the technical field of B32B7 / 00, specifically to a dual-layer, multi-level composite, pre-laid reverse-adhesive waterproof membrane. Background Technology

[0002] In current building construction, underground waterproofing is crucial, especially in preventing groundwater leakage in multi-story buildings and basements, which can lead to dampness and water accumulation, affecting the building's safety and lifespan. Traditional waterproofing materials are laid on a concrete subbase before concrete is poured to form the foundation structure. The waterproofing layer and the poured concrete exist in separate layers. Once the waterproofing layer is damaged and becomes permeable, water can seep through the porous structure of the concrete, resulting in dampness and water accumulation. Furthermore, waterproofing materials do not have the same lifespan as the building itself.

[0003] Chinese patent application number CN201910722171.8 discloses ARF-999 Gold Steel Armor polymer pre-laid waterproof membrane, which uses a multi-layered waterproof membrane applied to underground buildings. Although it can improve water penetration into the concrete structure, it cannot prevent water from further penetrating into the concrete structure through the puncture site after the waterproof membrane is damaged or punctured. Therefore, providing a waterproof membrane that can form mutual adhesion to the concrete structure and has excellent puncture resistance is the main technical problem that needs to be solved. Summary of the Invention

[0004] To address the above problems, this invention provides a dual-layer, multi-level composite, pre-laid reverse-adhesive waterproof membrane. The structural layers of the waterproof membrane are composed of, from top to bottom, an anti-adhesive protective layer, an upper surface adhesive layer, an upper substrate layer, an intermediate adhesive layer, a lower substrate layer, a lower surface adhesive layer, and an isolation layer, which are bonded together and connected to each other.

[0005] Preferably, the thickness of the anti-stick protective layer is 0.1-0.5 mm, and the material layer of the anti-stick protective layer includes a silicon dioxide layer and a silica coating.

[0006] Preferably, the thickness ratio of the silicon dioxide layer to the silica coating is (1-2):1.

[0007] The method for preparing the anti-stick protective layer includes the following steps:

[0008] S1. A silica layer is formed by coating the upper surface adhesive layer with silica.

[0009] S2. A silicate coating is applied to the formed silica layer and then quenched at high temperature to form a silica coating.

[0010] The silica has a fineness of 50 mesh.

[0011] In order to improve the bonding effect between waterproof membrane and concrete, the applicant unexpectedly discovered in experiments that applying a silica layer and a silicate coating to the upper surface adhesive layer can cause the anti-adhesive protective layer to react with calcium silicate in the concrete to generate silicate crystals. This allows the anti-adhesive protective layer to achieve a molecular structural connection with the concrete, resulting in a full bond between the waterproof membrane and the concrete structure, ensuring a lifespan comparable to that of the building and eliminating the risk of water seepage between the layers.

[0012] Preferably, the thickness of the upper surface adhesive layer is 0.5-1.0 mm, and the material of the upper surface adhesive layer is a barrier material.

[0013] The upper surface of the waterproof membrane is covered with a high-strength, high-specific-surface-area material that has undergone silica coating pretreatment followed by high-temperature quenching. Together with supramolecular ultraviolet blocking materials, it forms a protective layer against ultraviolet light and far-field rays.

[0014] Preferably, the barrier material is a supramolecular ultraviolet barrier material.

[0015] The supramolecular ultraviolet blocking material was purchased from Beijing Techleil Technology Co., Ltd., and its model number is ZWLQ-1.

[0016] Preferably, the thickness of the upper tire body layer is 0.05-0.12 mm, and the upper tire body layer is a multi-layer high-strength fiber layer.

[0017] Preferably, the thickness of the upper tire body layer is 0.065-0.10 mm.

[0018] Preferably, the upper tire body layer consists of multiple high-strength fiber layers, which are Kevlar high-strength fiber double layers.

[0019] Kevlar

[0020] To improve the puncture resistance of the waterproof membrane, the applicant has specified the thickness of the upper reinforcing layer to be 0.05-0.12 mm. The upper reinforcing layer is a multi-layer high-strength fiber layer, preferably a double-layer Kevlar high-strength fiber layer, which can increase the waterproof performance of the waterproof membrane, improve the tensile strength of the waterproof membrane, and further improve the puncture resistance of the waterproof membrane.

[0021] Preferably, the thickness of the intermediate adhesive layer is 0.5-1.2 mm, and the material of the intermediate adhesive layer is a flexible chain supramolecular adhesive.

[0022] Preferably, the preparation method of the flexible chain supramolecular adhesive includes the following steps:

[0023] By weight, 60-70 parts of asphalt are added to a mixing device and heated until the asphalt melts. Then, 20-30 parts of thermoplastic elastomer are added and stirred, and the mixture is heated to 210°C to obtain a flexible chain supramolecular adhesive.

[0024] Preferably, the thermoplastic elastomer is selected from one or more of styrene-butadiene-styrene block copolymers, linear triblock copolymers with ethylene-butene copolymers obtained by hydrogenation of polybutadiene as intermediate elastic blocks, TPE, and TPO; preferably, the thermoplastic elastomer is a styrene-butadiene-styrene block copolymer.

[0025] The styrene-butadiene-styrene block copolymer has a melt flow rate of 5 kg / 10 min at 200 °C.

[0026] The styrene-butadiene-styrene block copolymer with a melt flow rate of 5 kg / 10 min at 200°C was purchased from LG Chem in South Korea, and the model number is LG-512 styrene-butadiene-styrene block copolymer.

[0027] To enhance the adhesion between the upper and lower substrate layers and improve their elastic recovery after being subjected to external forces, the applicant discovered in experiments that the thickness of the intermediate adhesive layer is 0.5-1.2 mm. The intermediate adhesive layer is made of a flexible chain supramolecular adhesive. The raw materials for preparing the flexible chain supramolecular adhesive include asphalt and thermoplastic elastomers. Preferably, the thermoplastic elastomer is a styrene-butadiene-styrene block copolymer. The resulting flexible chain supramolecular adhesive can effectively function in the upper substrate layer and the special multiaxial warp-knitted dense substrate layer formed by the Kevlar high-strength fiber double substrate layer. When heated, the saturated molecules in the asphalt are easily absorbed by the styrene-butadiene-styrene block copolymer to form a swelling structure, which can form a dense interactive network structure with the asphalt, improving the adhesion between the upper and lower substrate layers and enhancing the elastic recovery performance of the waterproof membrane after being subjected to external forces.

[0028] Preferably, the thickness of the lower tire body layer is 0.7-1.5 mm, and the lower tire body layer is a special multi-axis warp-knitted dense tire body layer.

[0029] Preferably, the thickness of the lower tire body layer is 0.95-1.25 mm.

[0030] In order to improve the elastic recovery performance of the undercarriage layer after encountering external force, the applicant found in experiments that limiting the undercarriage layer to a special multi-axis warp-knitted dense undercarriage layer with a thickness of 0.7-1.5mm and weaving it through multi-axis warp knitting density can improve the shape retention of the undercarriage layer and enhance its elastic recovery performance.

[0031] Preferably, the thickness of the lower surface adhesive layer is 0.9-1.6 mm, and the material of the lower surface adhesive layer is a flexible chain polymer composite material.

[0032] Preferably, the preparation method of the flexible chain polymer composite material includes the following steps:

[0033] By weight, 60-70 parts of asphalt are added to a mixing device and heated until the asphalt melts. Then, 30-40 parts of thermoplastic elastomer are added and stirred, and the temperature is raised to 180-230℃. 5-8 parts of filler and 1-2% of the filler weight of modifier are added and stirred to obtain a flexible chain polymer composite material.

[0034] Preferably, the thermoplastic elastomer is selected from one or more of styrene-butadiene-styrene block copolymers, linear triblock copolymers with ethylene-butene copolymers obtained by hydrogenation of polybutadiene as intermediate elastic blocks, and olefin linear copolymers; preferably, the thermoplastic elastomer includes styrene-butadiene-styrene block copolymers and styrene-butadiene-styrene block copolymer modified materials.

[0035] The styrene-butadiene-styrene block copolymer has a melt flow rate of 5 kg / 10 min at 200 °C.

[0036] The styrene-butadiene-styrene block copolymer with a melt flow rate of 5 kg / 10 min at 200°C was purchased from LG Chem in South Korea, and the model number is LG SBS LG-512.

[0037] The styrene-butadiene-styrene block copolymer modified material was purchased from Kronen Japan, model number D1155 JOP.

[0038] Preferably, the filler is montmorillonite, and the particle size of the montmorillonite is 1-5 μm.

[0039] Preferably, the modifier is a silane coupling agent KH-570.

[0040] To improve the puncture and water resistance of waterproof membranes, the applicant unexpectedly discovered in experiments that the thickness of the lower surface adhesive layer (0.9-1.6 mm) and its material being a flexible chain polymer composite material, specifically prepared from asphalt, styrene-butadiene-styrene block copolymer, and montmorillonite, not only improves the adhesion between the lower surface adhesive layer and the release layer and the lower substrate layer, but also enhances the puncture and water resistance of the lower surface adhesive layer itself. The possible reason for this is the presence of asphalt, styrene-butadiene-styrene block copolymer, and montmorillonite. Ethylene block copolymers and styrene-butadiene-styrene block copolymer modifiers have certain long-chain structures. After heating, the long-chain structures can interpenetrate to form an interactive network structure. Montmorillonite, under the action of silane coupling agent KH-570, can interpenetrate into the formed network structure, which improves the strength of the lower surface adhesive layer, and also improves the adhesion durability between the isolation layer and the lower substrate layer and the water resistance of the waterproof membrane. In addition, the lower surface adhesive layer has relatively strong creep resistance and strong impact resistance, preventing the padding layer from cracking and water pressure from causing local damage to the waterproof material.

[0041] Preferably, the thickness of the isolation layer is 0.01-0.03 mm.

[0042] Preferably, the isolation layer is a thermoplastic polymer layer.

[0043] Preferably, the thermoplastic polymer material is selected from one or more of polyethylene, polypropylene, and polyamide.

[0044] Preferably, the thickness ratio of the upper tire body layer, the intermediate rubber layer, and the lower tire body layer is 1:(8-12):(11-15).

[0045] In this invention, by limiting the thickness ratio of the upper tire body layer, the intermediate rubber layer, and the lower tire body layer to 1:(8-12):(11-15), the elastic recovery performance of the upper and lower tire body layers after being subjected to external forces can be improved, and the puncture resistance is excellent. The possible reason is that limiting the thickness ratio can improve the effect of mutual adhesion between the layers. When the thickness of the intermediate rubber layer is small, it cannot effectively penetrate into the upper tire body layer and cannot effectively bond the upper and lower tire body layers.

[0046] Beneficial effects

[0047] The present invention provides a pre-laid waterproof membrane with a multi-layer structure, which enables the waterproof membrane to fully bond with the concrete structure, has the same lifespan as the building, eliminates the risk of water seepage in the middle, makes waterproofing safer, is suitable for underground construction projects of any shape, and is durable and has the same lifespan as the building.

[0048] This invention increases the waterproof performance of the waterproof membrane by limiting the thickness of the upper body layer and making the upper body layer a multi-layer fiber layer, and also improves the tensile strength and puncture resistance of the waterproof membrane.

[0049] In this invention, by limiting the material of the intermediate adhesive layer to a flexible chain supramolecular adhesive, the bonding performance between the upper and lower tire carcass layers can be enhanced, and the upper and lower tire carcass layers can have a certain elastic recovery performance after being subjected to external force, and have excellent puncture resistance.

[0050] In this invention, by defining the lower tire body layer as a multiaxial warp-knitted dense tire body layer, the elastic recovery performance of the lower tire body layer after encountering external force can be improved.

[0051] This invention improves the puncture resistance and water resistance of waterproof membranes by limiting the material of the lower surface adhesive layer to a flexible chain polymer composite material. Attached Figure Description
