Description

Technology Field

[0001] The present invention relates to a heating panel using a carbon fiber heating element and an SPC flooring material and a method for manufacturing the same. More specifically, the invention relates to a heating panel using an improved carbon fiber heating element and an SPC flooring material and a method for manufacturing the same, wherein the heat conduction efficiency is maximized by integrating a carbon fiber-based heating element inside an SPC (Stone Plastic Composite) flooring material, heat loss is minimized through a multi-layer structure including a functional layer based on oyster shells, electromagnetic waves and sparks are suppressed, and the construction process is drastically simplified. Background Technology

[0003] In general, floor heating technology for buildings has evolved into various forms, such as hot water circulation systems, electric film systems, and heating wire systems; however, each technology has various limitations in terms of heat transfer efficiency, constructability, stability, and durability.

[0004] In the case of the hot water circulation system, since it has a structure that circulates fluid heated by a boiler through internal floor piping, there is a problem of increased energy consumption due to the very slow heat transfer rate and long initial heating time, and structural issues such as pipe leakage and maintenance problems are also inherent.

[0005] The electric film method has the advantages of being relatively easy to install and having a thin structure, but it is vulnerable to physical damage to the film and poses a fire risk due to localized overheating, and issues regarding insulation degradation and electromagnetic wave generation are raised during long-term use.

[0006] In addition, it is inefficient in terms of maintenance costs, as film damage often requires the replacement of the entire system.

[0007] The technology of attaching heating wires to existing MDF-based flooring was introduced to simplify installation, but due to the low thermal conductivity of MDF itself, heat is not transferred evenly and significant heat loss occurs. Additionally, it is vulnerable to moisture, leading to deformation and corrosion issues during long-term use.

[0008] The method of inserting pipes inside stone or boards has structural limitations in that it forms a restricted heat transfer path, causing heat to concentrate in specific sections and making uniform heating of the entire area difficult; additionally, it suffers from the problem of slow heating speed due to low heat transfer efficiency.

[0009] Furthermore, the technology combining a heating structure with deco tile-based flooring also has issues such as slow heat transfer rates, the possibility of material deformation at high temperatures, and the occurrence of lifting and cracking due to repeated thermal expansion and contraction.

[0010] While heating element technology using carbon fiber offers advantages in terms of thermal efficiency and response speed, conventional technology suffers from issues such as spark generation and electromagnetic wave emission in the terminal structure, as well as a lack of long-term reliability due to low electrode contact stability.

[0011] Furthermore, existing heating systems have a structure in which flooring materials and heating elements are installed separately, resulting in a complex process and long construction time. Additionally, as the number of process steps increases, construction costs rise, and quality variations occur depending on the skill level of the workers.

[0012] In addition, in structures where different materials are laminated, delamination, cracking, and deformation may occur due to differences in thermal expansion coefficients, and there is a problem of reduced structural stability, particularly in environments with repeated temperature changes.

[0013] Furthermore, existing insulation structures often suffer from insufficient mechanical strength of the insulation material itself, leading to deformation or failure under floor loads, which frequently results in damage to the upper flooring.

[0014] Therefore, there is an urgent need for the development of integrated heating floor panel technology that can simultaneously satisfy thermal conductivity efficiency, structural stability, electrical safety, and constructability. Prior art literature

[0016] Registered Patent 10-2768419 Registered Patent 10-2332970 Registered Patent 10-2913243 The problem to be solved

[0017] The present invention aims to provide a heating panel and a method for manufacturing the same, which maximizes heat conduction efficiency through a multilayer structure that integrates a carbon fiber heating element and an SPC flooring material and includes an oyster shell-based functional layer, suppresses electromagnetic waves and sparks, simplifies the construction process, and simultaneously improves structural stability and durability. means of solving the problem

[0019] The present invention provides a heating panel using a carbon fiber heating element and an SPC flooring material, wherein the heating panel has a structure stacked from top to bottom as a means to achieve the above-mentioned purpose, comprising: a UV coating layer (100) for surface protection; a wear layer (110) located below the UV coating layer (100); a color film layer (120) located below the wear layer (110); an SPC core layer (130) located below the color film layer (120); a carbon fiber heating element layer (141) located below the SPC core layer (130) and including linear heating elements arranged linearly; an insulation layer (150) located below the carbon fiber heating element layer (141); and an oyster shell film layer (140) disposed between the carbon fiber heating element layer (141) and the insulation layer (150), which provides heat dispersion and insulation functions as well as transferring heat going down to the top only.

[0020] In addition, the present invention provides a method for manufacturing a heating panel comprising the steps of: preparing an SPC board; arranging a plurality of carbon fibers at regular intervals on the upper surface of the SPC board to form a heating element; forming electrodes at both ends of the arranged carbon fibers and forming an insulating structure in the electrodes and adjacent areas to ensure electrical connection stability and insulation; placing a film on the lower part of the carbon fiber heating element having the electrodes and insulating structure formed thereon, and attaching it to the carbon fiber heating element and the SPC board by applying pressure using a heat coating method; installing a temperature controller to control the temperature of the carbon fiber heating element; and placing an insulating layer on the lower part where the film is attached, and then attaching it to the SPC board, carbon fiber heating element, and insulating layer by applying pressure using a heat press method so that they become an integrated unit. Effects of the invention

[0022] According to the present invention, by directly arranging a carbon fiber heating element inside an SPC structure, the heat transfer path is shortened, resulting in a faster heating response speed and significantly improved thermal efficiency. Additionally, through an oyster shell-based film layer, the uniformity of heat transfer is enhanced, while insulation and spark prevention functions are strengthened.

[0023] In addition, mechanical strength and impact resistance are enhanced by the calcium carbonate and mineral components contained in the oyster shell, and additional functionality can be provided through far-infrared radiation properties.

[0024] In addition, by adopting a single SPC-based structure, deformation due to thermal expansion is minimized, and installation is possible without adhesive through the click-lock structure, thereby ensuring both environmental friendliness and ease of installation.

[0025] In addition, by optimizing the carbon fiber array structure and terminal design, electromagnetic wave generation can be suppressed and electrical stability ensured, while the high-strength structure of the insulation layer minimizes heat loss from the bottom and ensures long-term durability.

[0026] In particular, the manufacturing process is drastically simplified compared to existing methods, resulting in a reduction in the number of processes and a reduction in construction time and costs. Brief explanation of the drawing

[0028] FIG. 1 is an exemplary exploded view showing the layer structure of a heating panel according to the present invention. FIG. 2 is an exemplary process diagram showing a method for manufacturing a heating panel according to the present invention. FIGS. 3 to 9 show analysis results or certificates related to the verification of characteristics of the present invention. Specific details for implementing the invention

[0029] Hereinafter, preferred embodiments according to the present invention will be described in more detail.

[0030] The heating panel according to the present invention has a multilayer structure sequentially stacked from top to bottom, and is designed so that a plurality of functional layers are organically combined to integrally implement heat generation, heat transfer, heat dispersion, insulation, structural reinforcement, and thermal insulation functions.

[0031] This multilayer structure is not a simple stacked structure, but rather each layer is functionally linked to form a single integrated heating panel, and contributes to maximizing heating efficiency and stability through physical coupling and thermal linkage between each layer.

[0032] The heating panel according to the present invention includes a heating panel using a carbon fiber heating element and an SPC flooring material, characterized by comprising: a UV coating layer (100) for surface protection as shown in the example of FIG. 1; a wear layer (110) located below the UV coating layer (100); a color film layer (120) located below the wear layer (110); an SPC core layer (130) located below the color film layer (120); a carbon fiber heating element layer (141) including linear heating elements arranged linearly located below the SPC core layer (130); an insulation layer (150) located below the carbon fiber heating element layer (141); and an oyster shell film layer (140) disposed between the carbon fiber heating element layer (141) and the insulation layer (150) to provide heat dispersion and insulation functions, as well as to transfer heat going down only to the upper side.

[0033] At this time, the UV coating layer (100) forms the uppermost part of the heating panel according to the present invention, protecting the flooring from the external environment and contributing to maintaining durability during long-term use.

[0034] This UV coating layer (100) is formed by a UV curing method and provides resistance to external friction, contamination and chemical damage, while also performing a surface heat diffusion function to ensure that heat transferred to the lower layer is uniformly released to the outside.

[0035] This UV coating layer (100) has functional significance in that it goes beyond a simple protective layer and plays a role in uniformly spreading heat in the final stage of heat transfer.

[0036] In addition, the above-mentioned wear layer (110) provides resistance to repeated walking loads and external impacts, thereby extending the lifespan of the flooring.

[0037] In addition, the wear layer (110) acts as a mechanical buffer layer between the upper UV coating layer (100) and the lower color film layer (120) to absorb micro-deformation caused by heat and to disperse interlayer stress.

[0038] In addition, the color film layer (120) provides a design element that forms the appearance of the flooring material, and at the same time, acts as an intermediate layer that maintains uniformity of heat transfer between the upper layer and the lower structural layer.

[0039] In other words, it is characterized by performing a functional role of uniform heat distribution, going beyond mere aesthetic elements.

[0040] Meanwhile, the SPC core layer (130) is a structural core layer of the present invention and is composed of a composite material including pozzolan powder and calcium carbonate, providing high thermal conductivity and mechanical strength simultaneously.

[0041] The above SPC core layer (130) acts as a primary path for transferring heat upward and simultaneously performs a structural role in supporting the floor load.

[0042] In addition, the SPC core layer (130) is designed to have a low coefficient of thermal expansion so that deformation does not occur even with repeated temperature changes, and is configured to facilitate connection between adjacent panels through a click-lock structure.

[0043] In addition, the carbon fiber heating layer (141) has a linear heating structure in which a plurality of carbon fibers are arranged in a linear fashion at regular intervals.

[0044] The carbon fibers above generate resistive heat upon electrical application, and the arrangement spacing is precisely set considering the uniformity of heat distribution.

[0045] In particular, the carbon fiber heating element is configured to minimize electromagnetic wave generation by arranging the power supply directions to intersect, and is designed to prevent spark generation at the terminal portion through a copper plate electrode structure and an insulating tape structure.

[0046] This is because electromagnetic wave problems such as sparks do not occur only if the heating wires are arranged according to the arrangement method described in "Figs. 3 to 12" of the drawings in the publication of Patent No. 10-2620019, which was previously registered by Kusa Co., Ltd., a co-applicant of the present invention, so the previously registered patent can be referenced for this.

[0047] Therefore, the carbon fiber heating element layer (141) acts as a key element for controlling heat distribution beyond a simple heating function, and is combined with the upper oyster shell film layer (140) to form a structure that effectively disperses heat.

[0048] And, the above oyster shell film layer (140) is one of the core functional layers of the present invention and is formed by including an oyster shell-based material having calcium carbonate as the main component.

[0049] The above oyster shell film layer (140) assists in heat transfer between the heating element (referring to a linear heating element) and the insulation layer (150), while simultaneously acting as an insulating layer to ensure electrical safety.

[0050] Above all, the oyster shell film layer (140) plays an important role in reflecting the heat generated from the linear heating element so that it does not go down to the bottom, thereby transferring the heat only to the top.

[0051] In particular, the oyster shell film layer (140) serves to disperse the heat generated from the heating element over a wide area, thereby preventing local overheating and providing a uniform heating effect over the entire floor surface.

[0052] In addition, since oyster shell material has high mechanical strength, it stably supports the heating element and prevents deformation caused by external loads.

[0053] Furthermore, the mineral components contained in oyster shells possess far-infrared radiation emission properties, which provide not only heating efficiency but also additional functionality.

[0054] In addition, the insulation layer (150) serves to prevent heat from being lost downward and to concentrate it in the upward direction.

[0055] The above insulation layer (150) is formed as a composite structure including a PET-based structure and oyster shell components, having excellent compressive strength along with high insulation performance, preventing deformation due to floor load and improving the stability of the entire structure.

[0056] In addition, the insulation layer (150) includes a heat reflection function and performs the function of maximizing energy efficiency by reflecting the heat generated from the heating element upward.

[0057] This layered structure is characterized in that each layer does not function independently, but is organically combined to form a single heating panel.

[0058] That is, the heat generated in the carbon fiber heating element layer (141) is uniformly dispersed through the oyster shell film layer (140), transferred upward through the SPC core layer (130), and uniformly released to the outside through the color film layer (120), the wear layer (110), and the UV coating layer (100).

[0059] At the same time, the insulation layer (150) blocks heat loss to the lower part, thereby inducing the entire thermal energy to be concentrated to the upper part.

[0060] Through these structural interactions, the present invention provides significantly improved thermal efficiency and safety compared to existing technologies.

[0061] Here, the insulation layer (150) is formed by attaching an insulation material, and the insulation material may be made into a foam by foam molding an insulation composition comprising 30-40% by weight of oyster shell powder having an average particle size of 5㎛ (minimum 1-maximum 30㎛) and 60-70% by weight of recycled PET.

[0062] At this time, as shown in Figures 3 and 4, oyster shells contain various elements such as C, O, Mg, Al, Si, P, S, Ca, Cr, Fe, Cu, Zn, Br, Sr, Te, and U, which have characteristics that can contribute to antibacterial properties as well as humidity control, corrosion prevention, and improvement of tensile strength, impact strength, and tear strength.

[0063] In particular, to verify the thermal insulation performance using oyster shells and PET, the Korea Institute of Construction Standards and Testing was commissioned to confirm the characteristics as a low-carbon insulation material, and the results are attached in Fig. 5.

[0064] In addition, to verify radio wave compatibility when this insulation material is used as a floor heating material and combined with electronic devices, a request was made to the Korea Radio Testing & Research Institute on November 19, 2024, and a suitability judgment was received, which is attached in Fig. 6, and the certificate of suitability obtained by requesting the National Radio Research Institute is attached in Fig. 7.

[0065] In addition, to verify the far-infrared radiation characteristics through this insulation material, we commissioned the Korea Far-Infrared Application Evaluation Research Institute and obtained the results shown in Fig. 8. That is, it was confirmed that it also has far-infrared radiation characteristics.

[0066] In addition, the eco-friendly certification obtained by commissioning the Korea Environmental Industry & Technology Institute to verify the eco-friendliness of the heating panel according to the present invention is attached in Fig. 9.

[0067] In addition, in order to further enhance the properties of the thermal insulation material, the present invention may further add 5-7 parts by weight of sericite powder having a particle size of 5 μm, 2-4 parts by weight of barium ferrite powder having a particle size of 5 μm, 3-5 parts by weight of zirconium silicate having a particle size of 5 μm, and 3-5 parts by weight of encapsulated graphene with ammonium polyphosphate having a particle size of 5 μm to 100 parts by weight of the thermal insulation material composition.

[0068] In this case, sericite powder, as a natural mineral, maximizes electromagnetic wave absorption and shielding performance when combined with the porous characteristics of oyster shells. In particular, it suppresses electrostatic induction occurring within the insulation material and enhances indoor comfort by having a high far-infrared emissivity at room temperature. Furthermore, thanks to its fine plate-like structure, it also plays a role in supplementing compressive strength by reinforcing the air walls during PET foam molding.

[0069] Furthermore, although barium ferrite powder is a magnetic material not commonly used in general insulation materials, in this invention, it is dispersed specifically within a mixture of oyster shells and PET to dramatically improve sound insulation and soundproofing performance. Moreover, due to its high efficiency in converting sound energy into thermal energy, it not only secures a technical advantage as a noise-reducing insulation material but also provides a special function to suppress high-frequency noise generated inside and outside the building.

[0070] Furthermore, zirconium silicate addresses the brittleness issues that can arise in recycled PET, where crystallization due to thermal history can lead to easy breakage. By acting as a nucleating agent between PET chains during the high-temperature molding process to finely control crystal size, it enhances tear strength and impact resistance. Additionally, due to its very low coefficient of thermal expansion, it is excellent for ensuring the dimensional stability (prevention of deformation) of insulation materials even in environments with significant temperature fluctuations.

[0071] Furthermore, graphene powder encapsulated with ammonium polyphosphate provides self-extinguishing properties by forming a more robust char layer when the calcium carbonate component of oyster shells generates carbon dioxide during a fire. In particular, by utilizing the orientation of graphene, it is possible to realize a unique thermal anisotropy that facilitates horizontal heat diffusion within the insulation while blocking vertical (thickness) heat transfer, thereby enabling insulation performance to be boosted to the theoretical limit.

[0072] In addition, the aforementioned layer structure is broadly divided into three layers, and each layer has the following core functions.

[0073] The first layer refers to a UV coating layer (100), a wear layer (110), a column film layer (120), and an SPC core layer (130), and the first layer thus configured refers to the part of the flooring material that actually receives heat and transfers heat to the outside.

[0074] The second layer is a layer composed of a carbon fiber heating element layer (141) and an oyster shell film layer (140) that actually generates heat and transfers the heat to the first layer to produce a heating effect.

[0075] In particular, by refining and utilizing the calcium carbonate found in oyster shells, which were previously considered waste resources, tensile strength (strength when pulled), impact strength (strength when impacted), and tear strength (strength when torn) can be improved.

[0076] The third layer is an insulating layer (150) that efficiently captures the heat generated in the second layer and helps to send the heat to the first layer without any heat escaping from the second layer.

[0077] In addition, existing insulation materials have a defect in that the entire surface layer is damaged because they are not rigid, which has serious reliability issues. The present invention is characterized by the development to resolve the insulation material problem and the application of an insulation material that is resistant to impact and compression based on recycled oyster shells and PET.

[0078] On the other hand, a method for manufacturing a heating panel according to the present invention having such a layer structure includes, as shown in the example of FIG. 2, the steps of preparing an SPC board; aligning the prepared board in a connection direction; arranging carbon fibers at regular intervals; forming electrodes using copper tape and performing insulation treatment; installing wires and a thermostat; attaching a protective film using a heat coating device; and attaching an insulating material through a heat press process.

[0079] In addition, each step is performed sequentially to form an integrated structure.

[0080] This manufacturing method can improve production efficiency and minimize quality variations by being performed continuously without interruption between processes.

[0081] More specifically, in the initial stage of the manufacturing process, an SPC board preparation stage is performed.

[0082] In this step, a flooring material is prepared with an SPC core layer containing pozzolan and calcium carbonate, and the direction of the connecting clips on each board is aligned to enable precise lamination and bonding in subsequent processes.

[0083] At this stage, the SPC board must ensure surface flatness and thickness uniformity, and clip alignment is an important preliminary step to ensure the click-lock structure operates correctly during installation.

[0084] In the next step, the carbon fiber heating element arrangement step is performed.

[0085] In this stage, multiple carbon fibers are arranged in parallel at regular intervals using a dedicated array device, and the array spacing is designed considering thermal distribution uniformity and power consumption efficiency.

[0086] Furthermore, the arrangement direction of the carbon fibers is configured to intersect with the power supply direction to minimize electromagnetic wave generation, which acts as a factor that significantly improves electrical stability compared to conventional heating structures.

[0087] In addition, maintaining carbon fiber tension, ensuring straightness, and maintaining positional precision are very important in the above-mentioned arrangement step, and an automated alignment system can be applied for this purpose.

[0088] Next, after the carbon fiber arrangement is completed, electrode formation and insulation steps are performed.

[0089] In this step, electrodes are formed at both ends of the carbon fiber using copper tape (copper plate), and a contact surface for supplying current is secured.

[0090] Subsequently, short circuits and sparks are prevented by insulating the electrodes and carbon fiber connections using double-sided insulating tape.

[0091] This insulation step is a critical step for ensuring the electrical safety of the heating element, and the thickness, adhesion, and heat resistance of the insulation material are considered important design factors.

[0092] In particular, the laminated structure of the copper tape and the insulating tape must be designed to maintain electrode contact stability while preventing separation due to external shock or heat.

[0093] Then, the wire connection and thermostat installation steps are performed.

[0094] In this step, wires are installed to connect the carbon fiber heating element and the external power supply, and a thermostat for temperature control is placed on top of the heating element.

[0095] At this time, the thermostat performs the function of detecting and controlling the temperature of the heating element in real time, and is an important component for preventing overheating and optimizing energy efficiency.

[0096] In addition, the wire connections are configured to ensure resistance to external shocks and moisture through additional insulation and protective measures.

[0097] Then, the heat coating film attachment step is performed.

[0098] In this step, a protective film is attached to the bottom of the carbon fiber heating element, specifically to the top of the insulation layer, to block the transfer of heat generated from the heating element downwards and to redirect it so that it is transferred only upwards.

[0099] In this case, film attachment is performed using a heat coating device, and it is preferable to proceed by a heat press method under temperature conditions of about 150°C or higher.

[0100] This high-temperature pressing process maximizes the adhesion between the film and the heating element and improves heat transfer efficiency by eliminating micro-pores.

[0101] In addition, the film must be composed of a material with high thermal stability and designed so that deformation or degradation does not occur even in repetitive heating environments.

[0102] Subsequently, a step of attaching insulation material to form an insulation layer is performed.

[0103] In this step, insulation is placed beneath the film and integrated with the SPC structure using a heat press device.

[0104] In this case, the insulation material is formed by including a PET-based composite material and oyster shell components, and it is desirable to provide high compressive strength and excellent thermal insulation performance simultaneously.

[0105] In particular, the heat press operation improves the adhesion between the insulation, heating element, and SPC core layer, and strengthens interlayer adhesion, contributing to preventing interlayer separation or deformation during long-term use.

[0106] In addition, the insulation material maximizes energy efficiency by including a heat reflection function that reflects heat generated from the heating element back upward.

[0107] In particular, an important aspect of the manufacturing method of the present invention is that the oyster shell-based material is not merely an auxiliary material, but is applied in combination to the film layer and the insulation layer to simultaneously perform heat dissipation, insulation, and structural reinforcement functions.

[0108] Oyster shell material has a fine porous structure and a high calcium carbonate content, so it uniformly disperses heat transfer and simultaneously improves mechanical strength.

[0109] These characteristics contribute to ensuring that the heat generated by the heating element is distributed uniformly across the entire surface area rather than being concentrated in a specific region.

[0110] When using the heating panel manufactured in this way, conventionally, to install an electric heating film, one had to go through multiple processes, namely at least 7-8 processes, such as floor preparation → insulation work → film placement → wire connection → thermostat installation → protective plate installation → installation of deco tile, reinforced flooring, or SPC flooring. However, in the case of the present invention, installation can be done very easily, simply, and quickly by going through only 3 processes: floor preparation → floor installation (heating panel installation) → thermostat installation, thereby significantly improving installation efficiency.
