Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a heat-insulating curtain. Background Technology

[0002] As people's demands for living comfort and energy conservation increase, the function of curtains is no longer limited to simple light blocking and decoration. Traditional curtains are usually made of single or multiple layers of ordinary fabric, with very limited heat insulation, heat preservation, and sound insulation effects. In summer, strong solar radiation heat can enter the room through the windows, leading to a significant increase in air conditioning energy consumption; in winter, indoor heat is easily lost through the windows. In addition, outdoor noise can also affect the quietness of the indoor environment.

[0003] In existing technologies, although some composite curtains attempt to integrate heat insulation and light blocking functions, such as by using multi-layer fabric composites or adding heat insulation cotton layers, the following defects still exist: First, the heat insulation layer mostly uses ordinary foam or cotton wadding materials, which have a high thermal conductivity and limited heat insulation effect, and some materials have problems with poor environmental performance and easy aging; Second, the composite process of the light blocking layer and the heat insulation layer is simple, the interlayer bonding strength is low, and delamination is likely to occur after long-term use; Third, the integration of sound absorption function is not fully considered, or the sound absorption materials are not properly selected, resulting in poor sound absorption effect and increasing the overall thickness and weight of the curtain. Utility Model Content

[0004] This invention aims to address the technical problem of insufficient heat insulation, light blocking, and sound absorption functions in existing curtains. To overcome the shortcomings of the prior art, this invention provides a method that optimizes the composite layer structure design, selects high-performance materials, and improves the interlayer composite process to achieve a synergistic effect of efficient heat insulation, high light blocking rate, and excellent sound absorption performance. At the same time, it enhances the structural stability, environmental friendliness, and durability of the curtains, meeting the modern interior space's demand for multifunctional and high-quality curtains.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted: A heat-insulating curtain includes a curtain body comprising a first pile surface, a heat-insulating core, a composite light-blocking section, and a second pile surface, layered sequentially from the outdoor to the indoor side. The heat-insulating core includes an aerogel felt layer facing the outdoor side and a polymer foam layer facing the indoor side; a mesh fabric layer is bonded between the aerogel felt layer and the polymer foam layer. The composite light-blocking section includes a support layer, a sound-absorbing intermediate layer, and a light-blocking layer, layered sequentially from the outdoor to the indoor side. The support layer is made of a thin non-woven material, the sound-absorbing intermediate layer is made of a porous sound-absorbing material, and the light-blocking layer is made of a high-light-blocking fabric, with the sound-absorbing intermediate layer bonded to the light-blocking layer using a water-based adhesive. This curtain achieves a multi-functional integration of efficient heat insulation, complete light blocking, and sound absorption and noise reduction through a four-layer synergistic design of "first pile surface - heat-insulating core - composite light-blocking section - second pile surface". In particular, the insulation core employs a combination of an aerogel felt layer and a polymer foam layer, achieving both extremely low thermal conductivity and good thickness and cushioning performance. The mesh fabric layer in the middle significantly enhances the interlayer bonding force, solving the technical problem of easy delamination in multi-layer flexible materials and improving the product's structural stability and durability. Furthermore, the use of water-based adhesives avoids VOC pollution from traditional solvent-based adhesives, meeting environmental standards. The interlayer bonding method ensures a tight structure, reducing the risk of delamination over long-term use and extending the curtain's lifespan.

[0006] Preferably, the aerogel felt layer is composed of silica aerogel and glass fiber, and the thickness of the aerogel felt layer is 1mm to 5mm; the polymer foam layer is a closed-cell polyurethane foam, and the thickness of the polymer foam layer is 3mm to 10mm; the thickness of the polymer foam layer is greater than the thickness of the aerogel felt layer. By limiting the specific composition and thickness of the aerogel felt layer, and the specific type and greater thickness of the polymer foam layer, it is ensured that the thermal insulation core has excellent thermal insulation performance while maintaining a thin and lightweight overall structure with excellent mechanical toughness. The limited thickness ratio optimizes the balance between the product's mechanical support and thermal insulation performance, making the curtains less prone to deformation when hung, while ensuring optimal thermal insulation effect.

[0007] Preferably, the mesh fabric layer is made of glass fiber, and the basis weight of the mesh fabric layer is 20-80 g / m². The mesh fabric layer is bonded to the aerogel felt layer and the polymer foam layer respectively by a high-temperature resistant adhesive in a dotted or grid-like coating method. The glass fiber mesh fabric provides excellent tensile strength, and the specific basis weight range ensures good penetration and bonding strength without adding too much weight. Furthermore, the dotted or grid-like coating method avoids the material stiffness caused by full-surface adhesive coating, maximizing the overall flexibility and drape of the curtain.

[0008] Preferably, the support layer is made of one of thin polyester nonwoven fabric, polypropylene nonwoven fabric, or spunbond nonwoven fabric, with a basis weight ranging from 10-30 g / m². By limiting the material and basis weight of the support layer, it can provide sufficient support and flatness for the sound-absorbing intermediate layer, preventing its deformation, while avoiding adding extra weight and thickness due to its "thin" and "lightweight" characteristics, which is beneficial for composite processing and keeps the curtains lightweight.

[0009] Preferably, the sound-absorbing interlayer is made of one of the following: open-cell polyurethane foam, melamine foam, superfine glass wool, or environmentally friendly recycled cotton; the thickness of the sound-absorbing interlayer is 2-10mm. By listing various efficient and common porous sound-absorbing materials and defining their thickness range, the thickness of the light-blocking section is effectively controlled while achieving a significant sound absorption effect. This avoids making the curtains too thick and bulky due to the addition of a sound-absorbing interlayer, thus achieving a balance between functionality and practicality.

[0010] Preferably, the light-shielding layer is a high-density black polyester fabric, a light-shielding coated fabric, or a fabric with a black film sandwiched between layers. This structure provides a variety of specific material solutions for achieving high light-shielding performance, enhancing the feasibility of the solution.

[0011] Preferably, a first waterproof and breathable membrane is disposed between the first textured surface and the heat-insulating core. This first waterproof and breathable membrane is a polytetrafluoroethylene (PTFE) microporous membrane or a TPU membrane with a thickness of 0.01-0.1 mm. The first waterproof and breathable membrane effectively blocks external moisture or accidental water splashes from penetrating the heat-insulating core, preventing aerogel and other materials from becoming damp and failing, thus improving the product's environmental adaptability and service life. It allows internal moisture to escape, avoiding condensation between layers, preventing mold growth and material performance degradation, and maintaining the long-term stability of the heat insulation effect.

[0012] Preferably, a second waterproof and breathable membrane is provided between the heat insulation core and the composite light-shielding part. The second waterproof and breathable membrane is a polyethylene microporous membrane with a thickness of 0.01-0.1 mm. The first and second waterproof and breathable membranes provide bidirectional and more comprehensive protection for the heat insulation core.

[0013] Preferably, a third waterproof and breathable membrane is provided between the composite light-shielding part and the first textured part. The third waterproof and breathable membrane is a polytetrafluoroethylene microporous membrane or a TPU membrane with a thickness of 0.01-0.1 mm. The first, second, and third waterproof and breathable membranes provide bidirectional and more comprehensive protection for the heat insulation core.

[0014] Preferably, the curtain body is composed of multiple fabric units spliced ​​together by a connecting structure; the connecting structure is formed by magnetic strips, Velcro, or zippers. This modular splicing design solves the industry pain points of inconvenient production, transportation, and installation of large-size curtains. The magnetic strips, Velcro, and other connecting structures enable quick and flexible splicing and disassembly, facilitating cleaning, replacement, or width adjustment, greatly improving the product's practicality and convenience.

[0015] The advantages of this invention are: It achieves efficient heat insulation, thermal insulation, high light blocking, and sound absorption functions through a multi-layered structure. In summer, it reduces the transfer of solar radiation heat, and in winter, it reduces indoor heat loss. Furthermore, it attenuates mid-to-high frequency noise by 15-25 dB, significantly improving the indoor thermal and acoustic environment and enhancing living comfort. High-performance materials such as silica aerogel felt (low thermal conductivity), closed-cell polyurethane foam (efficient thermal insulation), and porous sound-absorbing materials (efficient sound absorption) are selected, combined with a waterproof and breathable membrane to ensure long-term stable performance of each functional layer. A mesh fabric layer enhances the interlayer bonding strength of the thermal insulation core. A water-based adhesive is used to composite the sound-absorbing intermediate layer and the light-blocking layer, along with a waterproof and breathable membrane to prevent moisture erosion and avoid delamination and peeling after long-term use. Simultaneously, the material selection balances flexibility and lightweight, ensuring flexible opening and closing of the curtains without compromising ease of use due to weight. The sound-absorbing intermediate layer and the light-blocking layer are composited with water-based adhesives, avoiding VOC pollution and the release of no harmful substances, ensuring indoor air safety. The curtain unit splicing design allows for flexible adaptation to windows of different sizes, reducing production and transportation costs; the partial replacement function reduces usage costs; and the elimination of the need for additional sound insulation panels, heat insulation films, and other products simplifies the interior decoration process and reduces overall investment.

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0019] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0020] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3As shown, a heat-insulating curtain includes a curtain body 1. The curtain body 1 includes a first fleece surface 11, a heat-insulating core 12, a composite light-blocking part 13, and a second fleece surface 14, which are stacked sequentially from the outdoor side to the indoor side. The heat-insulating core 12 includes an aerogel felt layer 121 facing the outdoor side and a polymer foam layer 122 facing the indoor side. A mesh fabric layer 123 is also bonded between the aerogel felt layer 121 and the polymer foam layer 122. The composite light-blocking part 13 includes a support layer 131, a sound-absorbing intermediate layer 132, and a light-blocking layer 133, which are stacked sequentially from the outdoor side to the indoor side. The support layer 131 is made of a thin non-woven material, and the sound-absorbing intermediate layer 132 is made of a porous sound-absorbing material. The light-blocking layer 133 is made of a high-light-blocking fabric, and the sound-absorbing intermediate layer 132 is composited with the light-blocking layer 133 by a water-based adhesive. This curtain achieves multi-functional integration of efficient heat insulation, complete light blocking, and sound absorption through a four-layer synergistic design consisting of a first layer (11), a heat-insulating core (12), a composite light-blocking layer (13), and a second layer (14). Specifically, the heat-insulating core (12) uses a combination of an aerogel felt layer (121) and a polymer foam layer (122), balancing extremely low thermal conductivity with good thickness and cushioning performance. The intermediate mesh fabric layer (123) significantly enhances interlayer bonding, solving the technical challenge of delamination in multi-layer flexible materials and improving the product's structural stability and durability. Furthermore, the use of water-based adhesives avoids VOC pollution associated with traditional solvent-based adhesives, meeting environmental standards. The interlayer bonding method ensures a tight structure, reducing the risk of delamination over long-term use and extending the curtain's lifespan.

[0023] like Figure 2As shown, the aerogel felt layer 121 is composed of silica aerogel and glass fiber, and the thickness of the aerogel felt layer 121 is 1mm to 5mm, with 2mm used in this embodiment. Silica aerogel is currently a solid material with extremely low thermal conductivity. Combining it with glass fiber can solve the problem of aerogel's brittleness and fragility, achieving excellent thermal insulation effect even with a thickness of 1-5mm, avoiding the problem of curtains being heavy and inconvenient to open and close due to excessively thick insulation layers. The polymer foam layer 122 is a closed-cell polyurethane foam. The closed-cell structure can block air convection and further reduce heat conduction. The thickness of the polymer foam layer 122 is 3mm to 10mm, with 6mm used in this embodiment. The thickness of the polymer foam layer 122 is greater than the thickness of the aerogel felt layer 121. The 3-10mm thickness design, combined with the aerogel felt layer 121, forms a "thin and efficient + thick auxiliary" thermal insulation combination. The polymer foam layer 122 is thicker than the aerogel felt layer 121, ensuring overall thermal insulation performance while also cushioning external forces and enhancing the overall flexibility of the curtains for everyday use. By limiting the specific composition and thickness of the aerogel felt layer 121, and the specific type and greater thickness of the polymer foam layer 122, the thermal insulation core 12 is ensured to possess superior thermal insulation performance while maintaining a lightweight and thin overall structure with excellent mechanical toughness. The mesh fabric layer 123 is made of glass fiber, with a basis weight of 20-80 g / m². In this embodiment, 50 g / m² is used. Glass fiber has high strength and high temperature resistance; the 20-80 g / m² basis weight design ensures mechanical support without significantly increasing the weight of the curtains. The mesh fabric layer 123 is bonded to the aerogel felt layer 121 and the polymer foam layer 122 respectively using a high-temperature resistant adhesive applied in a dotted or grid pattern. This method is suitable for high-temperature outdoor environments in summer, preventing adhesive failure at high temperatures. Furthermore, compared to full-surface coating, dotted or grid-pattern coating reduces adhesive usage and costs, while maintaining a certain degree of material breathability to prevent moisture accumulation between layers, which could lead to mold growth and performance degradation. The fiberglass mesh fabric provides excellent tensile strength, and the specific weight range ensures good penetration and bonding strength without adding excessive weight. The dotted or grid-pattern coating method avoids the stiffness caused by full-surface adhesive application, maximizing the overall flexibility and drape of the curtain.

[0024] like Figure 2As shown, the support layer 131 is made of one of the following: thin polyester nonwoven fabric, polypropylene nonwoven fabric, or spunbond nonwoven fabric, with a basis weight range of 10-30 g / m². In this embodiment, 20 g / m² is used. All three types of materials are lightweight and have moderate tensile strength. The low basis weight design of 10-30 g / m² provides stable support for the sound-absorbing intermediate layer 132 (preventing deformation and collapse of the sound-absorbing material) without increasing the overall thickness and weight of the curtain. Polyester nonwoven fabric has strong weather resistance, polypropylene nonwoven fabric is acid and alkali resistant, and spunbond nonwoven fabric is tear resistant. Appropriate materials can be selected according to different usage scenarios (such as the humid environment of a kitchen or the high-wear environment of a public space) to improve product applicability. In this embodiment, thin polyester nonwoven fabric is used. By limiting the material and weight of the support layer 131, it can provide sufficient support and flatness for the sound-absorbing intermediate layer 132 to prevent its deformation, while avoiding the addition of extra weight and thickness due to its "thin" and "lightweight" characteristics, which is conducive to composite processing and keeps the curtain lightweight.

[0025] like Figure 2 As shown, the sound-absorbing intermediate layer 132 is made of one of the following: open-cell polyurethane foam, melamine foam, superfine glass wool, or environmentally friendly recycled cotton. The thickness of the sound-absorbing intermediate layer 132 is 2-10mm, and 5mm is used in this embodiment. Open-cell polyurethane foam has good sound absorption and strong flexibility; melamine foam is heat-resistant and has a certain degree of heat insulation; superfine glass wool has a significant attenuation effect on mid-to-high frequency noise (such as traffic noise); and environmentally friendly recycled cotton meets green environmental protection requirements. Users can choose suitable materials according to the noise type (mid-to-high frequency / low frequency), usage scenario (home / public building), and environmental protection requirements to broaden the application range of the product. This embodiment uses open-cell polyurethane foam. The thickness range of 2-10mm ensures that the porous structure of the sound-absorbing material can fully exert its sound absorption effect (too thin a layer will result in insufficient sound absorption), while avoiding excessive thickness that would make the curtains heavy and take up space. At the same time, it matches the overall thickness of the composite light-blocking part 13, ensuring that the curtains have a flat appearance and smooth opening and closing. This example lists various efficient and common porous sound-absorbing materials and defines their thickness range. This allows the thickness of the blackout section to be effectively controlled while achieving a significant sound absorption effect, avoiding the curtains from becoming too thick and bulky due to the addition of the sound-absorbing intermediate layer 132, thus achieving a balance between function and practicality.

[0026] like Figure 2As shown, the light-blocking layer 133 is a high-density black polyester fabric, a light-blocking coated fabric, or a fabric with a black film sandwiched between layers. Specifically, the light-blocking layer 133 can be selected from high-density black polyester fabric (achieving light blocking through high-density weaving), light-blocking coated fabric (blocking light through a coating), or a fabric with a black film sandwiched between layers (achieving strong light blocking through a film). All three types of materials can achieve high light-blocking rates, meeting different light-blocking needs (such as complete light blocking in the bedroom or partial light blocking in the living room), and the materials are highly durable, with minimal risk of increased light transmittance over long-term use. This embodiment uses high-density black polyester fabric.

[0027] like Figure 2 As shown, a first waterproof and breathable membrane 15 is provided between the first fleece surface 11 and the heat insulation core 12. The first waterproof and breathable membrane 15 is a polytetrafluoroethylene (PTFE) microporous membrane or a TPU membrane; in this embodiment, a 0.05mm PTFE microporous membrane is used. The first waterproof and breathable membrane 15 effectively blocks external moisture or accidental splashes of water from entering the heat insulation core 12, preventing aerogel and other materials from becoming damp and failing, thus improving the product's environmental adaptability and service life. It allows internal moisture to escape, avoiding condensation between layers, preventing mold and material performance degradation, and maintaining the long-term stability of the heat insulation effect. Its thickness is 0.01-0.1mm, achieving waterproof and breathable functions without increasing the overall thickness and weight of the curtain, avoiding affecting the opening and closing and appearance of the curtain. Furthermore, PTFE and TPU materials have strong weather resistance, are not prone to aging or damage with long-term use, and are suitable for outdoor environments. A second waterproof and breathable membrane 16 is disposed between the heat insulation core 12 and the composite light-shielding part 13. The second waterproof and breathable membrane 16 is a polyethylene microporous membrane with a thickness of 0.01-0.1 mm; in this embodiment, 0.02 mm is used. A third waterproof and breathable membrane 17 is disposed between the composite light-shielding part 13 and the second textured part 14. The third waterproof and breathable membrane 17 is a polytetrafluoroethylene microporous membrane or a TPU membrane; in this embodiment, a 0.05 mm polytetrafluoroethylene microporous membrane is used. The first waterproof and breathable membrane 15, the second waterproof and breathable membrane 16, and the third waterproof and breathable membrane 17 provide more comprehensive protection for the heat insulation core 12.

[0028] like Figure 3As shown, the curtain body 1 is composed of multiple curtain fabric units 10 spliced ​​together by a connecting structure; the connecting structure is formed by magnetic strips, Velcro, or zippers. By adopting a modular splicing design, the industry pain points of inconvenient production, transportation, and installation of large-size curtains are solved. Three connection methods are provided: magnetic strips, Velcro, and zippers. Magnetic strip splicing is convenient (simply align to attract) and provides good sealing (reducing light leakage at the splice); Velcro splicing is low-cost and can be repeatedly disassembled; zipper splicing is sturdy and suitable for long-term fixed use. Different connection methods can adapt to different installation scenarios (e.g., Velcro for temporary home installation, zippers for long-term hotel use), improving the product's flexibility. At the same time, the splicing structure facilitates partial replacement (if a curtain fabric is damaged, only that piece needs to be replaced, without replacing the entire curtain, reducing usage costs). In this embodiment, as shown... Figure 3 As shown, the connection structure adopts a magnetic attraction structure design, with magnetic blocks set at the four corners of each curtain unit 10. The assembly and disassembly are achieved by the magnetic blocks between the two pieces of fabric attracting each other.

[0029] In summary, the advantages of this utility model are: Multifunctional integration: Through the original four-layer structure design of the first fleece surface 11, the heat insulation core 12 (aerogel felt layer 121 + polymer foam layer 122), the composite light-blocking part 13 (including sound-absorbing intermediate layer 132) and the second fleece surface 14, the functions of super heat resistance, full light blocking and sound absorption and noise reduction are perfectly integrated into one, with excellent comprehensive performance.

[0030] The structure is stable and prevents delamination: A mesh layer 123 is set between the aerogel felt layer 121 and the polymer foam layer 122 and a specific bonding method is used, which significantly improves the interlayer bonding strength and overall tensile strength of the heat insulation core 12, fundamentally solving the technical problem of easy delamination of multilayer flexible composite materials and extending the service life.

[0031] Significant thermal insulation effect: The aerogel felt layer 121, as the solid material with the lowest thermal conductivity in the world today, provides excellent thermal resistance. Combined with the closed-cell polymer foam layer 122, it forms a highly efficient thermal insulation barrier, which significantly reduces the energy consumption of air conditioning in summer and heating in winter.

[0032] Moisture-proof and breathable with excellent durability: The added waterproof and breathable membrane blocks liquid water while allowing water vapor to pass through, protecting materials such as aerogel from moisture, preventing internal condensation and mold growth, and ensuring long-term stable performance of the product in humid environments. The protective film on the first textured surface 11 also enhances its durability.

[0033] Combining practicality and aesthetics: The modular design enhances the product's portability and ease of use. The decorative surface layer at the end of the composite light-blocking section 13 allows the product to meet diverse aesthetic needs in interior design while maintaining powerful functionality.
