Abstract
Description
Technical Field
[0001] This invention relates to the field of building materials technology, and in particular to a waterproof membrane system for tunnels and underground engineering projects. Specifically, it relates to a pressure-bonded, reactive adhesive, and pressure-bonded reverse-adhesive waterproof membrane. Background Technology
[0002] During the construction of underground projects such as railway and highway tunnels, groundwater often seeps out. The hazards caused by tunnel water leakage include:
[0003] (1) Deterioration of the tunnel environment and impact on train safety. Long-term water leakage in tunnels, or even water inrush, can lead to lining cracks, tunnel floor collapse, paving or invert breakage, and mud pumping in the track bed, directly deteriorating the train operating environment. On electrified railways, water leakage in the tunnel arch can cause short circuits, tripping and discharge of power supply lines, affecting the normal operation of trains and endangering the safety of maintenance personnel.
[0004] (2) Reduce the service life of equipment in the tunnel and increase maintenance costs. Water leakage in the tunnel keeps the tunnel in a high humidity environment for a long time, which can accelerate the corrosion of rails, fasteners and other equipment, and greatly reduce their service life.
[0005] (3) It causes ground subsidence and affects the surrounding environment. For example, karst subsidence in Sichuan is mainly distributed in the karst mountains around the basin. In Chongqing, the completion of railway tunnels has caused regional groundwater depletion, which has induced a lot of karst subsidence in Gele Mountain and Zhongliang Mountain.
[0006] Therefore, waterproof membranes, as a widely used waterproof material, can effectively block groundwater infiltration and prevent concrete structures such as linings from being eroded by groundwater, causing disasters such as leaching corrosion, corrosive media corrosion, freeze-thaw damage, and steel reinforcement corrosion.
[0007] Waterproof membranes are typically composed of a waterproof substrate layer, an adhesive layer, and a release layer, laminated sequentially. Common types include high-density polyethylene (HDPE) waterproof membranes, low-density polyethylene (LDPE) waterproof membranes, polyvinyl chloride (PVC) waterproof membranes, and thermoplastic polyolefin (TPO) waterproof membranes. There are two common installation methods: one is through hot-melt welding, where thermoplastic round gaskets are welded to the surface of the waterproof membrane and then anchored to the initial support surface with nails; the other is using nails to nail the waterproof membrane to the initial support surface.
[0008] Chinese patent CN106700216B proposes a reverse-adhesive waterproof membrane and its preparation method. Through innovative formula adjustment, the isolation membrane layer does not need to be removed and directly reacts with the poured concrete and disappears, which greatly improves the waterproof membrane's impermeability and solves the leakage problem caused by local damage to the waterproof membrane. However, it is still lacking in terms of ease of installation and still adopts the traditional installation method.
[0009] Chinese patent CN120607762B proposes a waterproof membrane and its preparation method. By optimizing the raw material formula of the waterproof membrane, it solves the problem of low tensile strength at break and expands the application scenarios of the waterproof membrane. However, it still does not solve the problem of water leakage caused by local damage to the waterproof membrane.
[0010] However, the aforementioned prior art has the following drawbacks:
[0011] (1) The waterproof membrane itself has good impermeability, but if there is local damage to the surface, water will quickly fill the gap between the waterproof membrane and the secondary lining, and the waterproof system formed by the waterproof membrane will be destroyed.
[0012] (2) As a waterproofing material between the secondary lining and the initial support, there are two common ways to lay the waterproofing membrane: one is to heat-melt weld the thermoplastic round gasket to the surface of the waterproofing membrane and then anchor it to the surface of the initial support with nails; during the joint welding and spot welding installation process, the phenomenon of weak welding and weld penetration often occurs; the other is to use nails to nail the waterproofing membrane to the surface of the initial support. This method will directly puncture the waterproofing membrane. Even if it is "patched" by welding, there will still be gaps. The damage to the waterproofing membrane cannot be repaired. The tunnel waterproofing is actually entirely borne by the secondary lining.
[0013] (3) Regardless of the laying method, multiple operators are required to perform tedious operations, which greatly reduces construction efficiency and increases labor and material costs.
[0014] Therefore, the market urgently needs a new type of waterproof board that can adhere more tightly to the concrete surface, has high tensile strength, compressive strength and water resistance, and is easy to install without damaging the surface integrity. Summary of the Invention
[0015] In view of the above-mentioned deficiencies of the prior art, this application provides a pressure-bonded, reactive adhesive and a pressure-bonded and laid reverse-adhesive waterproof membrane. The pressure-bonded and laid reverse-adhesive waterproof membrane of this application is composed of a pressure-bonded, composite waterproof membrane and a reactive adhesive for connecting the pressure-bonded and waterproof membrane together.
[0016] The present invention has the following three advantages: (1) The waterproof membrane of the present invention has excellent waterproof performance and significantly enhanced tensile and compressive strength. The main layer of the waterproof membrane is bonded together with the anti-adhesive coating layer through reactive adhesive. When the waterproof layer is subjected to external force, the main layer of the waterproof membrane can undergo relative displacement deformation within the reactive adhesive layer, thereby giving full play to the high strength, puncture resistance, tear resistance and other properties of the main membrane. When cracks (temperature cracks, stress cracks, structural deformation cracks) occur in the concrete structure, the reactive adhesive layer can effectively eliminate the reflective damage of the structural cracks. When the main layer of the waterproof membrane peels off from the concrete structure, it ensures that the peeling failure surface occurs within the reactive adhesive layer, and that the reactive adhesive layer of a certain thickness is still attached to the surface of the concrete structure, ensuring that the concrete surface has sufficient impermeability.
[0017] (2) The waterproof membrane structure is intact and not damaged. When the composite waterproof membrane is laid, it is installed and fixed by injection molding and pressing, avoiding the occurrence of water seepage due to incomplete welding, missing welding or weak welding caused by hot melt welding, and avoiding damage to the surface of the waterproof membrane caused by nails.
[0018] (3) Convenient operation, saving manpower and installation costs. According to on-site tests, it only takes 2 people and 4 hours to install a 12-meter longitudinal section of composite waterproof membrane. In contrast, it takes 4 people and 12 hours to install a 12-meter longitudinal section of ordinary waterproof membrane.

[0066] On the other hand, the present invention provides a composite waterproof board, such as Figure 2 As shown ( Figure 3 The diagram shows the structure of the reverse-adhesive waterproof membrane before (A) and after (B) pressing and laying, which includes the sequentially stacked composite structure:
[0067] Waterproof membrane main layer (3);
[0068] A reactive adhesive layer (4), at least one of its main surfaces being bonded to the waterproof membrane body layer (3); and
[0069] An anti-stick coating layer (5) is disposed on the surface of the reactive adhesive layer (4) away from the waterproof membrane body layer (3).
[0070] The waterproof membrane main layer (3) is used to undertake waterproof, tensile and compressive functions, and its outer surface is in direct contact with the initial support; the reactive adhesive layer (4) is used to bond the waterproof membrane main layer (3) and the anti-stick coating layer (5), and the anti-stick coating layer (5) is used to protect the reactive adhesive layer (4). When the reaction between the anti-stick coating layer (5) and the poured concrete disappears, the reactive adhesive layer (4) comes into contact with the moisture in the concrete environment. The moisture-curing polyurethane prepolymer undergoes a moisture-curing reaction and simultaneously forms a chemical bond with the active groups on the concrete surface, accompanied by physical penetration and anchoring, thereby forming a complete, dense, and high-strength permanent bond. It provides a plastic deformation buffer against external force damage between the adhesive layer (4) and the concrete structure. The reactive adhesive layer (4) is used to isolate dust and contaminants in the air. Its core component, the moisture-curing polyurethane prepolymer, can directly react with the active hydroxyl groups on the surface of the secondary lining concrete after it is poured. After the silane coupling agent in the formula is hydrolyzed, its silanol groups condense with the silanol groups on the concrete surface, and the organic ends are embedded in the adhesive layer network, thereby constructing a stable 'molecular bridge' at the interface. This achieves chemical bonding and physical anchoring between the film layer and the cement concrete, improving the density of the concrete surface.

[0210] The preparation method of the pressure-adhesive and reverse-adhesive waterproof membrane of the present invention is as follows:
[0211] 1. Preparation of pressure bonding
[0212] (1) Preparation of the pressed and pasted hook teeth and lifting holes
[0213] Polypropylene, EPDM rubber, chopped glass fiber, first antioxidant, and first light stabilizer are precisely measured according to the formula, mixed evenly, and then fed into an injection molding machine. Under the set temperature and pressure, the mixture is injected into a mold with a hook-tooth structure. After cooling and solidification, it is demolded to obtain a hook-tooth strip semi-finished product.
[0214] (2) Preparation of the pressed and bonded base plate
[0215] The first linear low-density polyethylene, ethylene-vinyl acetate copolymer, maleic anhydride-grafted polyolefin elastomer, first silane coupling agent, special compatibilizer, second antioxidant, and second light stabilizer are measured and blended according to the specified ratio. This mixture is then fed into another injection molding machine and injected into a flat base mold. After molding, it is demolded.
[0216] (3) Composite and finished product processing
[0217] The injection-molded hook teeth are firmly bonded to the lifting holes and base plate using hot pressing or high-frequency welding to form a complete press-fit. Finally, the press-fit is cut to the specified width and length according to construction requirements and packaged for later use.
[0218] 2. Preparation of composite waterproof membrane
[0219] (1) Preparation of the main layer (3) of the waterproof membrane
[0220] According to the weight proportions, the methyl vinyl silicone rubber, special compatibilizer, and 20% of the total mass of the second ethylene-vinyl acetate copolymer used in the main layer (3) of the waterproof membrane are pre-mixed and granulated to produce a uniform silicone rubber masterbatch. Then, the remaining second ethylene-vinyl acetate copolymer, metallocene polyethylene, modified high-density polyethylene, stabilizer, and third antioxidant are accurately weighed and fed together with the silicone rubber masterbatch into a co-rotating parallel twin-screw extruder through the main feed port. Dynamic vulcanization is completed under the high shear of the screw and precise temperature control (150℃~170℃). After complete plasticization and uniform mixing, the melt is extruded through a T-die and finally calendered by a three-roll calender to obtain the main layer (3) of the waterproof membrane.
[0221] (2) Preparation of reactive adhesive layer (4)
[0222] According to the weight proportions, brominated butyl rubber, polybutene, polyolefin elastomer, thixotropic agent, and fourth antioxidant for the reactive adhesive layer (4) are added to a planetary mixing vessel that can be heated and vacuumed. The mixture is melt-blended and dehydrated under continuous stirring at 110-130°C. The above adhesive is cooled to 40-50°C, and under continuous stirring and moisture-free conditions, a moisture-curing polyurethane prepolymer and a second silane coupling agent are added. After hot-melt mixing and degassing, a hot-melt adhesive liquid is obtained. On the production line adjacent to the waterproof membrane main layer (3), the lower adhesive layer of the waterproof membrane main layer (3) is first corona-treated to enhance its surface energy and reactivity, facilitating bonding with the anti-adhesive coating layer (5). After the mixed hot-melt adhesive is transported to the hot-melt adhesive coating head through an insulated pipe, the adhesive is directly applied to the surface of the waterproof membrane main layer (3) before it has completely cooled, forming the upper adhesive layer. The thickness of the adhesive layer is precisely controlled by adjusting the gap of the coating die or the roller speed.
[0223] (3) Preparation of the anti-stick coating layer (5)
[0224] Prepare the raw materials for the anti-stick coating layer (5) according to the weight proportions. In a mixing tank, heat deionized water to 80-90°C and slowly add polyvinyl alcohol while stirring until it is completely dissolved to form a transparent adhesive. After the polyvinyl alcohol solution cools to below 50°C, add metakaolin, bentonite, ultraviolet shielding agent and crosslinking agent in sequence. Use a high-speed disperser to stir until all powders are evenly dispersed to form a stable slurry, and then perform vacuum degassing. Apply the prepared polyvinyl alcohol slurry evenly to the lower adhesive layer of the anti-stick coating layer (5). Then, the sheet enters a multi-segment tunnel drying oven and slowly and thoroughly dries the moisture at a gradient temperature of 60°C to 110°C to form a continuous solid anti-stick coating layer (5).
[0225] (4) Post-processing
[0226] The three-layer composite sheet is cooled and shaped by a set of cooling rollers; the thickness of the product is continuously monitored by an online thickness gauge, and the edges on both sides are trimmed by an automatic edge trimming machine to ensure consistent width.
[0227] 3. Preparation of Press-Adhesive Reverse-Adhesive Waterproof Board
[0228] The composite waterproof membrane is bonded to the second tape body by reactive adhesive, and the finished product is rolled up under constant tension.
[0229] Alternatively, the composite waterproof membrane and the second tape can also be bonded together by heat pressing.
[0230] The above-mentioned method for laying the reverse-adhesive waterproof membrane is as follows:
[0231] (1) During the tunnel construction process, when the initial support is laid, nails are used to nail the first strip body to the surface of the initial support, and one first strip body is nailed at each of the four corners of each square meter.
[0232] (2) With the main layer of the composite waterproof membrane facing the initial support surface, find the four corners of the second tape and align it with the first tape on the initial support surface.
[0233] (3) Press the first and second strips to complete the laying of one square meter of composite waterproof board.
[0234] (4) Repeat (1) to (3) above to complete the waterproofing work on the tunnel arch and sides.
[0235] Compared with the prior art, this application has the following beneficial technical effects:
[0236] (1) In the waterproof membrane main layer system, the addition of metallocene polyethylene and modified high-density polyethylene improves the toughness and tensile and compressive properties of the waterproof membrane; in the reactive adhesive layer system, the use of polyolefin elastomer and moisture-curing polyurethane prepolymer effectively enhances the adhesion between the reactive adhesive and the waterproof membrane main body, while promoting the bonding between the reactive adhesive and concrete, and consuming external impact loads through plastic deformation; in the anti-adhesive coating layer system, polyvinyl alcohol is selected as the film-forming and bonding main body, with higher alcoholysis degree, and kaolinite can provide solid content to improve brushability; by adding short glass fiber, the rigidity, strength and creep resistance of injection molding press-bonded hooks and lifting holes are improved; in the injection molding press-bonded base plate system, the molecular structure of maleic anhydride grafted polyolefin elastomer has "amphiphilicity", which can act as a "molecular bridge" between the originally incompatible polypropylene and linear low-density polyethylene, ethylene-vinyl acetate copolymer, and significantly improve the interfacial bonding through physical entanglement and chemical bonding.
[0237] (2) Complete waterproof membrane system: Excellent waterproof performance and significantly enhanced tensile and compressive strength. The main layer of the waterproof membrane is bonded together with the anti-adhesive coating layer through the reactive adhesive layer. When the waterproof layer is subjected to external forces, the main layer of the waterproof membrane can undergo relative displacement deformation within the reactive adhesive layer, thereby giving full play to the high strength, puncture resistance, tear resistance and other properties of the main membrane. When cracks occur in the concrete structure (temperature cracks, stress cracks, structural deformation cracks), the reactive adhesive layer can effectively eliminate the reflective damage of the structural cracks. When the main layer of the waterproof membrane peels off from the concrete structure, it ensures that the peeling failure surface occurs within the reactive adhesive layer, and that the reactive adhesive layer of a certain thickness is still attached to the surface of the concrete structure, ensuring that the concrete surface has sufficient impermeability. When the composite waterproof membrane is laid, it is installed and fixed by injection molding and pressing, avoiding the occurrence of water seepage due to incomplete welding, missing welding or weak welding caused by hot melt welding, and avoiding damage to the surface of the waterproof membrane caused by nails.
[0238] (3) The installation and use process is convenient and saves manpower and installation costs. According to the field test, it only takes 2 people and 4 hours to install a 12-meter longitudinal section of composite waterproof membrane. In contrast, it takes 4 people and 12 hours to install a 12-meter longitudinal section of ordinary waterproof membrane. Attached Figure Description

[0249] Referring to section 5.1 "Internal Quality" of GB / T 23315-2009 Hook and Loop Tape, Table 1 "Internal Quality Requirements" specifies the requirements for shear strength, peel strength, fatigue resistance (after 1000 clutch cycles), and fatigue resistance (after 3000 clutch cycles) of reinforced hook and loop tape. The test results of the press-fit tapes prepared in Examples 1-4 are shown in Table 2 below.

[0254]
[0255] Comparative Example 6:
[0256] Compared with Example 1, HG type whisker silicon, CAS20071002, distributed by Shanghai Huijing Asia Nano New Materials Co., Ltd., was used to replace the short-cut glass fibers.
[0257] Comparative Example 7:
[0258] Compared with Example 1, maleic anhydride-grafted elastomer 800E (based on polyethylene copolymer elastomer with a grafting rate of 1.0-1.3%) from Nanjing Feiteng New Material Technology Co., Ltd. was used instead of maleic anhydride-grafted polyolefin elastomer.
[0259] Comparative Example 8:
[0260] Compared with Example 1, the titanate coupling agent of model 105 produced by Guangzhou Zhongjie New Materials Co., Ltd. was used instead of the silane coupling agent.
[0261] Comparative Example 9:
[0262] Compared to Example 1, nitrile rubber of grade N220S manufactured by JSR of Japan was used instead of ethylene propylene diene monomer (EPDM) rubber.
[0263] Comparative Example 10:
[0264] For products containing other compatibilizers, Mitsui Chemicals ADMER QF541E adhesive polyolefin material should be used instead of Coes maleic anhydride-grafted polypropylene B1A.
[0265] Experimental Example 2
[0266] Referring to section 5.1, "Internal Quality Requirements," of GB / T 23315-2009 Hook & Loop Tape, the requirements for shear strength, peel strength, fatigue resistance (after 1000 cycles of engagement and disengagement), and fatigue resistance (after 3000 cycles of engagement and disengagement) of reinforced hook and loop tapes were tested on samples 1-10. The test results are shown in Table 4 below.
[0267] Table 4 Results of Comparative Tests of Press-Adhesion Preferences
[0268]
[0269] The comparison between the examples and comparative examples shows that Comparative Example 1, lacking chopped glass fibers, had an initial shear strength of 11.0 N / cm², resulting in insufficient rigidity due to the absence of fiber reinforcement. After 3000 clutch cycles, its performance deteriorated drastically, with a shear strength of 5.9 N / cm², indicating severely degraded fatigue resistance. The absence of maleic anhydride-grafted polyolefin elastomer in Comparative Example 2 significantly reduced the peel strength of the compression bond. Comparative Example 3 exhibited a precipitous drop in all strengths because the dedicated compatibilizer, acting as an interface strengthener between the hook teeth, lifting holes, and the base plate, weakened the bonding between these interfaces, causing the hook teeth and lifting holes to detach directly from the base plate. Comparative Example 4 verified the plasticizing properties of EPDM rubber; its absence led to brittle hook teeth / lifting holes, reduced impact and repeated bending resistance, and more severe performance degradation after fatigue. Comparative Example 5, lacking a silane coupling agent, showed a slight decrease in peel strength. Comparative Example 6 exhibited poor whisker silica flowability, affecting injection molding filling and preventing the production of finished products. Comparative Example 7 exhibited an initial peel strength of 1.2 N / cm, far below the standard requirement, and failed the fatigue resistance test. Comparative Example 8 was incompatible with the system and could not form strong Si-O-Si covalent bonds with the silicone rubber component in the reactive adhesive. The base plate made by replacing Comparative Example 9 with nitrile rubber was incompatible with the hook teeth / lifting holes, resulting in phase separation during blending. The compatibilizer in Comparative Example 10 had poor flowability and was incompatible with the injection molding process.

The test results are shown in Table 6 below.

[0283] Test Example 4
[0284] Referring to the standard "Railway Tunnel Drainage and Waterproofing Materials Part 1: Waterproof Membrane - Q / CR 562.1-2018", section 4.5.3.2, "Overall Performance of Reverse-Adhesive Waterproof Membrane", Table 6, "Peel Strength After Bonding with Post-Pouring Concrete" (item 6), "Peel Strength After Surface Treatment with Post-Pouring Concrete" (item 7), the peel strength after bonding with post-pouring concrete and the peel strength after surface treatment of the waterproof membranes made in Comparative Examples 11-17, as well as their water-resistant properties (0.6 MPa), were tested. The test results are shown in Table 8 below.
[0285] Table 8 Test Results of Composite Waterproof Membrane
[0286]
[0287] The comparison between the examples and comparative examples shows that Comparative Example 11, lacking methyl vinyl silicone rubber, significantly reduces the overall performance of the waterproof membrane, especially the peel strength under UV and heat aging conditions, demonstrating the important role of methyl vinyl silicone rubber in broadening the material's working temperature range and improving durability. Comparative Example 12, lacking a silane coupling agent, significantly reduces the viscosity of the reactive adhesive layer, which is detrimental to the bonding of the three layers of the waterproof membrane. Comparative Example 13 verifies the importance of polybutene for achieving reliable construction bonding and ensuring interface density; the lack of polybutene greatly affects the peel strength between the surface-treated membrane and the subsequently poured concrete. Comparative Example 14 shows that the UV shielding agent plays a crucial role in improving the waterproof membrane's resistance to UV radiation and heat aging. Comparative Example 15 shows a severely insufficient rigidity in the waterproof membrane layer, with the membrane itself being too soft. Comparative Example 17 is technically impossible to achieve; such a thinness is not feasible.

In comparison, the peel strength to the self-adhesive film of the samples prepared in Examples 9-12 was generally higher than that of the comparative example, and the surface drying time of Examples 9 and 10 was shorter than that of the comparative example.
