Abstract
Description
Technical Field
[0001] This application relates to the technical field of waterproof materials, and in particular to a multi-layer composite high-elasticity waterproof membrane. Background Technology
[0002] As a key material in modern building waterproofing systems, building waterproofing membranes must withstand dynamic water pressure of 0.8-1.5 MPa and adapt to extreme temperature differences from -30℃ to +100℃ in structures such as roofs, basements, and subway tunnels. According to the JC / T 234-2008 standard, high-quality membranes should possess a 28-day impermeability strength of ≥0.6 MPa, an elongation at break of ≥350%, and resistance to 100,000 thermal cycles. Currently, most mainstream products on the market use a composite structure of polyvinyl chloride (PVC) substrate and polyester mesh fabric, with seams formed by hot air welding. Their right-angle tear strength generally reaches 18 kN / m.
[0003] The existing technology has significant technical shortcomings: First, due to the difference in modulus (polyurethane coating 0.5mm thick) between the protective layer and waterproof layer (1.2mm thick PVC) of traditional roll materials, thermal expansion misalignment of 0.12-0.25mm / m occurs under alternating temperature conditions, resulting in an annual leakage of up to 4.8L / (m²·a). Second, when the reinforcing layer uses ordinary non-woven fabric (200g / m²), its ultimate tensile strength is only 8kN / m, and it exhibits 1.2% creep under 10kPa negative wind pressure, causing the peel strength at the joint to decrease to 30% of that of the base material. Third, after aging in a humid and hot environment at 60℃ for 480h, the 180° peel strength of the existing adhesive layer decreases from the initial 1.5kN / m to 0.6kN / m, and the high-temperature welding at 120℃ during construction generates benzene emissions (concentration up to 110mg / m³). These defects result in the current roll materials having a service life of less than 50% of the design requirements under the combined effects of acid and alkali corrosion (pH 3-11), freeze-thaw cycles (-20℃ / 40℃ alternation), and mechanical impact (50J / m²). Utility Model Content
[0004] In order to solve the problems mentioned in the background art, this application provides a multi-layer composite high-elasticity waterproof membrane.
[0005] This application provides a multi-layer composite high-elasticity waterproof membrane, employing the following technical solution: It includes a protective mechanism for enhancing the membrane's elasticity and a fixing mechanism for increasing composite performance. A circular shaft is fixedly connected to one side of the protective mechanism, and a fixing mechanism is provided on one side of the circular shaft. The membrane is disposed on the outer side of the protective mechanism. The fixing mechanism includes a heat dissipation layer, an adhesive layer is fixedly connected to one side of the heat dissipation layer, and an adhesion layer is fixedly connected to one side of the adhesive layer. The protective mechanism includes a protective layer installed inside the composite layer. An adsorption layer is fixedly connected to the bottom of the composite layer, a reinforcing layer is provided at the upper end of the adsorption layer, and a support layer is provided at the upper middle part of the reinforcing layer.
[0006] Optionally, a cross protective layer is provided on one side of the circular shaft, and a fixing mechanism is provided on one side of the cross protective layer.
[0007] The above solution enhances the protective performance of the roll material by setting a cross-protective layer on one side of the circular shaft, effectively resisting external damage. The fixing mechanism on the other side of the cross-protective layer ensures the stability of the roll material during laying or installation, preventing the roll material from shifting, thus improving the waterproof effect and service life of the roll material.
[0008] Optionally, the protective layer is thermoplastic vulcanized rubber, the adsorption layer is spandex, the composite layer is a composite film, the reinforcing layer is EVA foam, and the supporting layer is silicone rubber.
[0009] The above scheme uses thermoplastic vulcanized rubber for the protective layer, making it wear-resistant and aging-resistant; the absorbent layer uses spandex to effectively absorb and disperse external impact; the composite layer is a composite film to enhance the barrier of the roll material and prevent moisture and chemical substances from penetrating; the reinforcing layer uses EVA foam to improve the roll material's compressive strength and flexibility; and the support layer is silicone rubber to provide a stable support structure and ensure that the roll material maintains its shape stability in complex environments.
[0010] Optionally, the heat dissipation layer is carbon fiber reinforced plastic, the adhesive layer is basalt fiber, and the attachment layer is polyethylene fiber.
[0011] The above scheme uses carbon fiber reinforced plastic for efficient heat dissipation; basalt fiber for adhesive layer to ensure strong bonding between layers; and polyethylene fiber for attachment layer to provide flexibility and impact resistance, enhancing the stability of the overall structure.
[0012] Optionally, the thickness of the protective layer is 2mm-3.5mm, and the thickness of the composite layer is 1mm-2.5mm.
[0013] With the above scheme, the thickness of the protective layer is set between 2mm and 3.5mm, which can effectively prevent external physical damage and chemical erosion while maintaining the flexibility of the roll material; the thickness of the composite layer is between 1mm and 2.5mm, which enhances the barrier properties of the roll material while avoiding the overall rigidity caused by excessive thickness, ensuring that the roll material still has good adaptability and durability in complex environments.
[0014] Optionally, the reinforcing layer has a thickness of 0.2mm-0.35mm, the attachment layer has a thickness of 0.3mm-0.35mm, and the heat dissipation layer has a thickness of 0.2mm-0.15mm.
[0015] The above solutions effectively improve the tensile and compressive strength of the roll material and enhance structural stability by using a reinforcing layer with a thickness between 0.2mm and 0.35mm. The adhesion layer with a thickness between 0.3mm and 0.35mm provides flexibility and impact resistance to the roll material, ensuring the integrity of the overall structure. The heat dissipation layer with a thickness between 0.2mm and 0.15mm enables efficient heat dissipation.
[0016] In summary, this application includes the following beneficial technical effects:
[0017] This invention, by incorporating components such as a protective mechanism, a composite layer, a protective layer, and an adsorption layer, and through the synergistic relationship between the protective layer, the composite layer, and the adsorption layer, enables the protective layer to protect the roll material through its excellent wear resistance and aging resistance; the composite layer to effectively block moisture and chemicals through its composite membrane structure; and the adsorption layer to disperse external impacts through its high elasticity and hygroscopicity, thus protecting the internal structure of the roll material. This solves the problem that traditional waterproof roll materials struggle to balance waterproofing performance and protective capabilities, and are easily damaged by external environmental factors, thereby improving the waterproofing safety of building structures.
[0018] This invention addresses the shortcomings of traditional waterproof membranes in terms of elasticity and composite performance, making them unsuitable for use in complex environments. By incorporating reinforcing and supporting layers in the protective structure, and heat dissipation, adhesive, and attachment layers in the fixing mechanism, the reinforcing layer, through EVA foam, enhances the tensile and compressive strength of the membrane, thereby increasing structural stability. The supporting layer, using silicone rubber, provides a stable support structure, ensuring the membrane maintains its shape under complex conditions. The heat dissipation layer, using carbon fiber reinforced plastic, achieves efficient heat dissipation, preventing heat accumulation. The adhesive layer, using basalt fiber, ensures strong bonding between layers. The attachment layer, using polyethylene fiber, provides flexibility and impact resistance. This design solves the problems of traditional waterproof membranes' insufficient elasticity and composite performance, making them unsuitable for use in complex environments, and improves the adaptability and durability of the membrane.

[0025] This application discloses a multi-layer composite high-elasticity waterproof membrane.

[0027] It should be explained that the protective mechanism 1 is used to improve the elasticity of the roll material. It has a round shaft 5 fixed on one side and a roll material 3 on the outside. Its interior includes a protective layer 11, a composite layer 13, an adsorption layer 12, a reinforcing layer 14, and a support layer 15, which can enhance protection, enhance barrier properties, absorb moisture and protect against moisture, improve tensile and compressive strength and stable support effect. The fixing mechanism 2 is used to increase the composite performance. It is located on one side of the round shaft 5 and includes a heat dissipation layer 21, an adhesive layer 22 and an attachment layer 23, which can efficiently dissipate heat and ensure that each layer is firmly bonded.
[0028] Please see Figures 1 to 4 A cross protective layer 4 is provided on one side of the circular shaft 5, and a fixing mechanism 2 is provided on one side of the cross protective layer 4.
[0029] It should be explained that a cross protective layer 4 is provided on one side of the round shaft 5 to enhance the protective effect, and a fixing mechanism 2 is provided on the other side of the cross protective layer 4. It works in conjunction with the protective mechanism 1 and the cross protective layer 4 to improve the compositeness of the roll material, so that each layer is firmly bonded and the overall performance of the roll material can be enhanced.
[0030] Please see Figures 1 to 4 The protective layer 11 is thermoplastic vulcanized rubber, the adsorption layer 12 is spandex, the composite layer 13 is a composite film, the reinforcing layer 14 is EVA foam, and the support layer 15 is silicone rubber.
[0031] It should be explained that the protective layer 11 is made of thermoplastic vulcanized rubber, which has excellent wear resistance and aging resistance, providing protection for the roll material. The absorbent layer 12 is made of spandex, which can disperse external impact. The composite layer 13 is a composite film, which enhances the barrier properties of the roll material and prevents moisture and chemical substances from penetrating. The reinforcing layer 14 is EVA foam, which improves the tensile and compressive strength of the roll material. The support layer 15 is silicone rubber, which provides a stable support structure and ensures the stability of the roll material shape.
[0032] Please see Figures 1 to 4 The heat dissipation layer 21 is made of carbon fiber reinforced plastic, the adhesive layer 22 is made of basalt fiber, and the attachment layer 23 is made of polyethylene fiber.
[0033] It should be explained that the heat dissipation layer 21 is made of carbon fiber reinforced plastic, which can dissipate heat efficiently and avoid heat accumulation. The adhesive layer 22 is made of basalt fiber to ensure strong bonding between the layers of the roll material. The attachment layer 23 is made of polyethylene fiber, which provides flexibility and impact resistance, and enhances the adaptability and durability of the roll material.
[0034] Please see Figures 1 to 4 The thickness of the protective layer 11 is 2mm-3.5mm, and the thickness of the composite layer 13 is 1mm-2.5mm.
[0035] It should be explained that the thickness of the protective layer 11 is set between 2mm and 3.5mm. This thickness provides good protection without being too heavy and affecting the overall performance of the roll material. The thickness of the composite layer 13 is 1mm to 2.5mm. This thickness range helps to control the total thickness and weight of the roll material, making it easier to construct and use.

This thickness range provides sufficient strength to enhance the tensile and compressive strength of the roll material while keeping it lightweight. The thickness of the attachment layer 23 is between 0.3mm and 0.35mm. This thickness helps to provide flexibility and impact resistance, enabling the roll material to better adapt to various complex environments. The heat dissipation layer 21 can efficiently dissipate heat and prevent heat accumulation without adding too much weight or thickness, thus not affecting the overall performance of the roll material.
[0038] The implementation principle of the multi-layer composite high-elasticity waterproof membrane in this application embodiment is as follows:
[0039] First, the multi-layered composite high-elasticity waterproof membrane enhances its elasticity and protective performance through the protective mechanism 1. The layers within the protective mechanism 1 work together: the protective layer 11 provides basic protection, the composite layer 13 strengthens the barrier, the absorbent layer 12 disperses impact force, the reinforcing layer 14 improves tensile and compressive strength, and the supporting layer 15 ensures shape stability, collectively coping with complex external environments.
[0040] Secondly, the fixing mechanism 2 enhances the composite performance through the heat dissipation layer 21, the adhesive layer 22, and the attachment layer 23. The heat dissipation layer 21 dissipates heat efficiently, the adhesive layer 22 ensures that each layer is firmly bonded, and the attachment layer 23 provides flexibility and impact resistance, making the layers of the roll material tightly bonded together and improving the adaptability and durability of the roll material.
[0041] Finally, the circular shaft 5 and the cross-protective layer 4 further enhance the structural stability and protective effect of the roll material. The circular shaft 5 serves as a connection point, allowing the protective mechanism 1 and the fixing mechanism 2 to be tightly integrated. The cross-protective layer 4 provides additional protection, working in conjunction with the fixing mechanism 2 to improve the overall performance of the roll material and ensure that it can perform excellent waterproof and elastic effects in various environments.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
