Description

Technical Field

[0001] This utility model relates to the field of waterproof board technology, and in particular to a multi-layer lightweight waterproof board. Background Technology

[0002] In construction engineering, waterproofing is a crucial step in ensuring the structural safety and functionality of buildings.

[0003] Traditional waterproofing boards have many shortcomings. For example, while some waterproofing boards offer some waterproofing performance, their heavy weight increases the load on buildings, compromising structural stability and making handling and installation difficult during construction. Some lightweight boards have poor waterproofing performance, easily leading to leaks that affect the building's lifespan and indoor environmental quality. Furthermore, traditional waterproofing boards have a relatively simple structure, making them unsuitable for complex building environments and diverse waterproofing needs. With the development of the construction industry, the performance requirements for waterproofing boards are becoming increasingly stringent. Therefore, developing a novel, multi-layered waterproofing board that combines lightweight design with high-efficiency waterproofing performance is of significant practical importance.

[0004] To address the above problems, we propose a multi-layer lightweight waterproof board. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-layer lightweight waterproof board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-layer lightweight waterproof membrane includes a base layer, on the upper side of which a waterproof layer, a reinforcing layer, and a protective layer are sequentially disposed; the base layer includes a baseboard, on the inner side of which honeycomb holes are formed and filled with sound-insulating foam; the waterproof layer includes a polymer self-adhesive waterproof membrane layer and a nano-waterproof coating, the polymer self-adhesive waterproof membrane layer is bonded to the upper side of the baseboard, and the nano-waterproof coating is applied to the upper side of the polymer self-adhesive waterproof membrane layer.

[0008] Furthermore, the sound-insulating foam is made of polyurethane.

[0009] Furthermore, the polymer self-adhesive waterproof membrane layer is a polymer polyethylene polypropylene composite waterproof membrane.

[0010] Furthermore, the reinforcing layer includes a glass fiber mesh and a carbon fiber reinforced mesh, wherein the glass fiber mesh is bonded and laid on the upper side of the nano-waterproof coating, and the carbon fiber reinforced mesh is bonded and laid on the upper side of the glass fiber mesh.

[0011] Furthermore, the protective layer includes a UV protective coating and an abrasion-resistant coating, wherein the UV protective coating is applied to the upper side of the carbon fiber reinforced mesh, and the abrasion-resistant coating is applied to the upper side of the UV protective coating.

[0012] Furthermore, the UV protective coating is an acrylic UV protective coating.

[0013] Furthermore, the wear-resistant coating is a polyurethane wear-resistant coating.

[0014] Compared with related technologies, the multi-layer lightweight waterproof board proposed in this utility model has the following beneficial effects:

[0015] The base layer uses lightweight honeycomb structure material, which greatly reduces the weight of the waterproof membrane. At the same time, the design of the honeycomb structure and the reinforcing layer gives it high strength and can withstand certain external forces, meeting the dual requirements of lightweight and high strength for waterproof membranes in construction projects.

[0016] The combination of a polymer self-adhesive waterproof membrane layer and a nano waterproof coating forms a double waterproof barrier, effectively preventing water penetration and providing excellent waterproof performance. Even in long-term humid or complex environments, it can ensure the stability of the waterproof effect.

[0017] The thermal and sound insulation materials filled in the base layer give the waterproof membrane excellent thermal and sound insulation performance, which can effectively reduce heat transfer and sound transmission between the inside and outside of the building, and improve the building's energy efficiency and indoor environmental quality.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-4 A multi-layer lightweight waterproof board includes a base layer 1, on which a waterproof layer 2, a reinforcing layer 3, and a protective layer 4 are sequentially arranged; the base layer 1 includes a base board 11, on which honeycomb holes 12 are formed, and the inside of the honeycomb holes 12 is filled with sound-insulating foam 13; the waterproof layer 2 includes a polymer self-adhesive waterproof membrane layer 21 and a nano waterproof coating 22, the polymer self-adhesive waterproof membrane layer 21 is bonded to the upper side of the base board 11, and the nano waterproof coating 22 is coated on the upper side of the polymer self-adhesive waterproof membrane layer 21.

[0025] In this method, the sound insulation foam 13 is made of polyurethane.

[0026] Through the above-described configuration, polyurethane sound insulation foam has a closed-cell structure, which effectively blocks the transmission of sound and provides good sound insulation. The porous structure of polyurethane foam not only has good sound insulation but also absorbs a certain amount of noise, further reducing the noise level. The closed-cell structure of polyurethane also helps to isolate heat transfer, providing excellent thermal insulation.

[0027] In this method, the polymer self-adhesive waterproof membrane layer 21 is a polymer polyethylene polypropylene composite waterproof membrane.

[0028] Through the above-described design, polyethylene-polypropylene composite waterproof membranes typically consist of a multi-layered structure, including upper and lower polyethylene films and a middle layer of polypropylene fibers. This multi-layered structure effectively prevents water penetration, providing reliable waterproofing. The polyethylene material itself has excellent water resistance, allowing the membrane to maintain its waterproof performance even in long-term humid environments. The middle polypropylene fiber layer provides the membrane with high strength and tensile strength, enabling it to resist cracking and deformation of the substrate. Furthermore, polyethylene-polypropylene composite waterproof membranes do not produce harmful substances during production and use, posing no harm to the environment or human health.

[0029] In this method, the reinforcing layer 3 includes a glass fiber mesh 31 and a carbon fiber reinforced mesh 32. The glass fiber mesh 31 is bonded and laid on the upper side of the nano waterproof coating 22, and the carbon fiber reinforced mesh 32 is bonded and laid on the upper side of the glass fiber mesh 31.

[0030] With the above-mentioned setup, the glass fiber mesh 31 has good stiffness, which enables the entire material system to have high resistance to deformation when reinforcing the material structure. Glass fiber has high tensile strength, which can effectively enhance the material's performance in the tensile direction. The carbon fiber reinforced mesh 32 has a lower density than glass fiber and other traditional fiber materials, which makes the carbon fiber reinforced mesh lighter in weight while providing the same strength.

[0031] In this method, the protective layer 4 includes a UV protective coating 41 and a wear-resistant coating 42. The UV protective coating 41 is coated on the upper side of the carbon fiber reinforced mesh 32, and the wear-resistant coating 42 is coated on the upper side of the UV protective coating 41. The UV protective coating 41 is an acrylic UV protective coating, and the wear-resistant coating 42 is a polyurethane wear-resistant coating.

[0032] Through the above-mentioned setup, the acrylic UV protective coating can effectively block the erosion of ultraviolet rays, prevent the waterproof membrane from aging, and extend its service life; the polyurethane wear-resistant coating improves the surface hardness and wear resistance of the waterproof membrane, making it less susceptible to scratches and wear during construction and use.

[0033] The working principle of the multi-layer lightweight waterproof board provided by this utility model is as follows:

[0034] In use, each layer of this multi-layer lightweight waterproof membrane works synergistically. The lightweight honeycomb structure of the base layer disperses stress, reducing its own weight and building load. The polyurethane sound-insulating foam within the honeycomb cells provides thermal and sound insulation through its closed-cell structure. The high-molecular-weight polyethylene-polypropylene composite waterproof membrane layer of the waterproof layer relies on the upper and lower polyethylene films for water resistance, the middle polypropylene fiber layer for reinforcement, and the dense membrane. The nano-waterproof coating, with its extremely low surface tension, causes water to bead up and prevents penetration, forming a double waterproof barrier. The glass fiber mesh of the reinforcing layer disperses stress and restrains interlayer displacement, while the carbon fiber reinforced mesh enhances strength and fatigue resistance while maintaining lightweight properties. The acrylic UV-protective coating of the protective layer absorbs and scatters ultraviolet rays to prevent aging, while the polyurethane wear-resistant coating improves surface hardness and wear resistance. The unique properties of each layer work together to achieve lightweight, highly efficient waterproofing, thermal and sound insulation, high strength, and good durability, meeting diverse building needs.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
