Description

Heating mat for road snow melting and its manufacturing device

[0001] The present invention relates to a heating mat for road snow melting and a manufacturing device thereof.

[0002] In general, a heating mat is a flat heating device that is laid on the floor of a building to warm the floor.

[0003] Unlike boilers, these heating mats are simple to install and can be installed in a very short time because they only need to be laid on the floor. They are thin and light, making them easy to transport, and they are easy to install, manage, and store.

[0004] In particular, they eliminate the need for extensive construction during remodeling projects, are extremely simple to install, and require virtually no maintenance or upkeep after installation. Furthermore, heating mats boast high thermal efficiency, making them widely used as replacements for conventional boilers and electric heating wires for heating buildings, road snow melting, greenhouses, livestock sheds, and other agricultural and livestock industries.

[0005] A conventional heating mat comprises a heating unit. The heating unit comprises a first synthetic resin (PET) film, a heating unit having copper wires arranged vertically on both sides of the inner surface thereof using silver paste and copper, a heating unit having a carbon component arranged in parallel horizontally at regular intervals between the copper wires on both sides, and a second synthetic resin film positioned above the copper wires and the heating unit and bonded to the first synthetic resin film through thermal compression. However, such a heating unit is vulnerable to waterproofing, which makes it difficult to use in heating construction using wet concrete.

[0006] In addition, the heating mat disclosed in Korean Patent Publication No. 10-2012-0138343 provides a heating unit that generates heat when current flows, including a carbon component, a waterproof protective film made of urethane material that wraps the heating unit for waterproofing, and a sealing part processed by high frequency or low frequency along the edge of the waterproof protective film to seal the edge.

[0007] However, these heating mats have a problem in that an air layer is formed between the heating unit and the waterproof protective film, and this air layer causes the surface smoothness of the concrete to deteriorate during the pouring of wet concrete, or causes condensation to occur due to internal temperature differences.

[0008] In addition, the heating mat disclosed in Korean Patent Publication No. 10-1404328 provides a heating unit that includes a carbon component and generates heat when current flows, a waterproof protective film made of urethane material that wraps the heating unit for waterproofing, a sealing portion processed with high frequency or low frequency along the edge of the waterproof protective film to seal the edge, and an air exhaust portion that connects the inside and the outside of the waterproof protective film on one side of the waterproof protective film.

[0009] However, since the conventional heating mat provides a technology in which the air exhaust part is concentrated on one side of the waterproof protective film, when wet concrete is poured, the air in the middle of the waterproof protective film cannot escape but is trapped, and an air layer still remains between the heating unit and the waterproof protective film. This air layer causes a problem in that condensation phenomenon still occurs due to the internal temperature difference, and when electricity flows to the heating unit, there is a problem in that the building's circuit breaker trips due to a leakage of electricity caused by static electricity and moisture generated by condensation between the heating unit and the waterproof protective film.

[0010] In addition, conventional heating mats have problems in that electromagnetic waves may be generated when current flows, causing interference to surrounding electronic devices or systems, and heat may be concentrated in a specific area due to the generation of resistive resistance and / or capacitive resistance.

[0011] The technical problem to be solved by the present invention is to provide a heating mat and a manufacturing device thereof that can protect the surrounding environment and electronic devices by blocking electromagnetic waves generated while current is supplied to a carbon plate by a shielding sheet, and can also increase electrical efficiency and reduce power loss by eliminating resistive resistance and / or capacitive resistance, and can maintain improved or long-term stable performance in various environments (e.g., indoors or outdoors with high ceilings, snow melting on roads, etc.) by utilizing radiant heat.

[0012] According to one embodiment of the present invention, a heating mat for road snow melting comprises: a carbon plate containing a carbon component, generating heat when current flows through it, and generating radiant heat; a shielding sheet provided on the upper and lower surfaces of the carbon plate; a waterproof sheet provided on the outer surface of the shielding sheet; and a protector provided on the outer surface of the waterproof sheet, made of EPDM rubber, electrically insulating and sealing; and after the heating mat for road snow melting is buried in a floor surface, the ground is heated by far-infrared radiant heat generated by the carbon plate, and at the same time, an object provided in an internal space above the ground is heated, and an air layer is heated by the heated object, thereby enabling indoor heating without limitation on floor height. The shielding sheet is characterized in that it blocks electromagnetic waves generated when the carbon plate generates heat, thereby preventing interference with electronic devices, and reduces power loss and increases heat generation efficiency by eliminating electrical capacitive resistance.

[0013] According to one embodiment of the present invention, the outer surface of the waterproof sheet and the inner surface of the protector facing the outer surface are treated with a chemical agent and adhered to each other to have a waterproof function.

[0014] The shielding sheet according to one embodiment of the present invention is characterized in that it is made of polyvinyl chloride, a metal thin film, or a mesh form.

[0015] According to one embodiment of the present invention, a device for manufacturing a heating mat for road snow melting comprises: a support frame; an upper waterproof sheet supply drum rotatably provided on one side of the support frame and continuously supplying an upper waterproof sheet; a lower waterproof sheet supply drum rotatably provided on the other side of the support frame and continuously supplying a lower waterproof sheet; a carbon plate supply drum rotatably provided between one side and the other side of the support frame and continuously supplying a carbon plate; an upper shielding sheet supply drum provided on the support frame and provided between the upper waterproof sheet supply drum and the carbon plate supply drum and continuously supplying an upper shielding sheet; a lower shielding sheet supply drum provided on the support frame and provided between the lower waterproof sheet supply drum and the carbon plate supply drum and continuously supplying a lower shielding sheet; and a joint part provided on the support frame and bonding the upper waterproof sheet, the upper shielding sheet, the carbon plate, the lower shielding sheet, and the lower waterproof sheet while being laminated, thereby continuously drawing out a heating mat for road snow melting.

[0016] The joint according to one embodiment of the present invention is characterized by including a first joint roller unit that pressurizes and bonds the upper waterproof sheet, the upper shielding sheet, the carbon plate, and the lower shielding sheet in a sequentially stacked state, and a second joint roller unit that pressurizes and bonds the lower waterproof sheet in a stacked state on the lower portion of the lower shielding sheet that has passed through the first joint roller unit.

[0017] According to one embodiment of the present invention, a heating mat for road snow melting and a manufacturing device thereof can protect the surrounding environment and electronic devices by blocking electromagnetic waves generated while current is supplied to a carbon plate by a shielding sheet, and can also increase electrical efficiency and reduce power loss by eliminating resistive resistance and / or capacitive resistance, and can maintain improved or long-term stable performance in various environments (e.g., indoors or outdoors with high floor heights, and road snow melting with a floor thickness of 300 to 500 mm) by utilizing radiant heat.

[0027]

[0028] Referring to FIGS. 1 to 3, a heating mat for road snow melting according to one embodiment of the present invention may include a carbon plate (110), a shielding sheet (120), and a waterproof sheet (130).

[0029] The carbon plate (110) contains a carbon component, generates heat when current flows, and can generate radiant heat.

[0030] Here, since the carbon plate (110) generates radiant heat not in a specific area but in the entire area, the generated radiant heat is evenly transferred to the floor material (mortar, concrete, asphalt, soil, marble, etc.) on which the road snow melting heating mat (100) is installed, and can be quickly heated.

[0031] Furthermore, the radiant heat evenly transmitted through the flooring is released into the upper space, directly heating objects placed there (e.g., furniture, ceiling, walls, etc.). The radiant heat from the heated objects is then released back into the upper space, heating the air layer in the upper space. In this way, as the air layer is heated, the upper space is heated evenly throughout.

[0032] Here, since radiant heat heats objects directly without using air as a medium, it can efficiently transfer heat not only to the ceilings, walls, and furniture in interior spaces of high-ceilinged buildings, but also to concrete and asphalt on outdoor roads.

[0033] That is, after the road snow melting heating mat (100) of the present invention is buried in the ground, the ground is heated by the far-infrared radiation heat generated by the carbon plate (110), and at the same time, objects (e.g., furniture, ceiling, wall, etc.) provided in the internal space above the ground can be directly and evenly heated, and the heated objects emit heat, so that the indoor air layer is heated, enabling indoor heating. In particular, since objects such as the ceiling, walls, and furniture are evenly heated, heat is not concentrated at a specific point, and uniform heating is possible throughout the entire room without any floor height restrictions.

[0034] For example, a heating mat (100) for road snow melting can quickly generate radiant heat in 30 to 40 minutes based on mortar poured at a thickness of 50 mm, enabling efficient heating.

[0035] In particular, the radiant heat method can effectively transfer heat even in spaces with high ceilings or wide spaces, regardless of floor height. This allows heating even in areas with a floor height of 20 m simply by operating the heating mat (100) for road snow melting. Furthermore, mortar thicknesses of 500 mm or more are possible for road snow melting.

[0036] In conventional electric ondol heating and electric hot water pipe heating, when the floor height is high, EHP (Electric Heat Pump) and air conditioning heating are used, but in the road snow melting heating mat (100) of the present invention, heating is possible without the additional use of EHP and air conditioning heating.

[0037] Here, we explain conductive heat, convective heat, and radiant heat.

[0038] First, conduction heat transfers directly through solid materials, transferring heat from high-temperature areas to low-temperature areas through molecular collisions. A representative example is the heat generated in the heating tubes (nichrome wire) installed in electric underfloor heating systems and electric hot water pipes, which are then conducted through the mortar.

[0039] Conduction heat transfers heat directly, minimizing energy loss. However, it has the disadvantage of limited heat transfer range and high underfloor heating installation costs. In particular, because the material itself takes time to heat, conduction heat has limitations, requiring a long period of time for heating to occur. Furthermore, conduction heat cannot heat the air.

[0040] Convection is the process by which heat circulates through the air. When heat from a heat source heats the air, the heated air rises, while the cool air sinks, creating a circulating flow. Examples include radiator heaters and fan heaters.

[0041] This type of convection heat can efficiently heat a wide space because heat is transferred through the air, and the heating effect can be achieved quickly because the air is quickly purified.

[0042] However, convection heat can cause a greater temperature difference between the upper and lower levels as the floor height increases. Because heated air tends to rise, in spaces with high floor heights, warm air tends to accumulate at the top, while relatively cold air tends to accumulate at the bottom. This reduces heating efficiency, requires more energy to keep the lower levels warm, and increases costs by requiring longer heating system operation or the installation of additional heating devices.

[0043] Radiant heat is a method of heat transfer through electromagnetic waves, particularly infrared. This means that the heat source directly transfers energy to an object or person. Examples include infrared heaters and carbon-based heating mats for road snow melting.

[0044] This type of radiant heat transfers energy directly through electromagnetic waves, resulting in immediate heat transfer from the moment the heat source is turned on. This technology offers the advantage of high energy efficiency by directly transferring heat to the object.

[0045] In particular, radiant heat does not use air as a medium, but directly heats objects that are touched by electromagnetic waves. In the case of heating using radiant heat, objects in indoor spaces are heated when they are touched by electromagnetic waves, so the walls, ceilings, floors, other furniture, road concrete, asphalt, etc. in indoor spaces can be quickly heated as a whole.

[0046] In addition, heated walls, ceilings, floors, and furniture radiate heat into the indoor space, so the indoor heating is possible quickly by convection heat radiating from all directions, there are no floor height restrictions, and heat loss is very low, so there are advantages in efficient heating.

[0047] The related content is explained in detail through the examples, comparative examples and experimental examples described below.

[0048] Additionally, carbon components have low electrical resistance, allowing electrons to be emitted when current flows. When the carbon plate (110) is heated by the current, the thermal energy can separate electrons in the surrounding air and combine with air molecules to form negative ions.

[0049] Here, as the carbon plate (110) generates heat and generates negative ions, it can help purify indoor air and maintain a pleasant environment. In other words, the heating mat (100) for road snow melting can improve indoor air quality in addition to simply providing heating.

[0050] In addition, negative ions can reduce stress, improve blood circulation, and strengthen immunity. They can also increase perceived temperature, making you feel warmer even if the actual temperature is slightly lower, thus reducing energy consumption.

[0051] The shielding sheet (120) may be provided on the upper and lower surfaces of the carbon plate (110). Accordingly, the shielding sheet (120) may include an upper shielding sheet (121) provided on the upper surface of the carbon plate (110) and a lower shielding sheet (122) provided on the lower surface of the carbon plate (110).

[0052] That is, the shielding sheet (120) may be formed in the form of a metal thin film or mesh to block electromagnetic waves generated when the carbon plate (110) is heated, thereby preventing interference with electronic devices, and to reduce power loss and increase heat generation efficiency by eliminating electrical resistive resistance and / or capacitive resistance. In the present invention, the shielding sheet (120) may be formed in the form of a mesh, but is not limited thereto.

[0053] Here, resistive resistance and / or capacitive resistance reduce the efficiency of the electric circuit and increase power loss. This can be caused by electromagnetic interference. That is, the shielding sheet (120) blocks electromagnetic waves and eliminates resistive resistance and / or capacitive resistance, thereby enabling efficient current flow and increasing the electrical efficiency of the road snow melting heating mat (100), thereby improving the overall performance of the road snow melting heating mat (100).

[0054] Meanwhile, the heating mat for road snow melting according to the present invention may further include a reflective sheet (not shown).

[0055] A reflective sheet (insulating material) may be provided on one side of a road snow melting heating mat (100) to increase the efficiency of the road snow melting heating mat (100).

[0056] Specifically, a reflective sheet (insulating material) may be provided between the lower part of the road snow melting heating mat (100), that is, the base floor surface, and the carbon plate (110).

[0057] Heat is not transferred to the base floor surface by the reflective sheet (insulation material) but only to the upper side, thereby increasing the heat efficiency of the heating mat (100) for road snow melting and maximizing the heating effect.

[0058] These reflective sheets (insulation materials) may be made of one material among foamed polyethylene, aluminum, copper, stainless steel, or a mixture of one or more materials, but are not limited thereto.

[0059] For example, the reflective sheet (insulation material) may be made of, but is not limited to, foamed polyethylene, aluminum foil, or aluminum-coated sheet.

[0060] Meanwhile, in the road snow melting heating mat (100) of the present invention, a carbon plate (110), a shielding sheet (120), and a waterproof sheet (130) are pressed by a roller or the like and can be closely (i.e., tightly adhered) to each other.

[0061] For example, a laminated shielding sheet (120) may be laminated on the upper and lower sides of a carbon plate (110), and a waterproof sheet (130) may be laminated on the outer surface of the shielding sheet (120) and / or the carbon plate (110).

[0062] Accordingly, the heating mat (100) for road snow melting can prevent condensation caused by the air layer by preventing an air layer from being formed between each layer (meaning the carbon plate (110) and the shielding sheet (120) and the waterproof sheet (130)) (between the carbon plate (110) and the shielding sheet (120), between the shielding sheet (120) and the waterproof sheet (130), etc.).

[0063] In addition, the waterproof sheet may include polyvinyl chloride, which forms the substrate, and an antistatic agent that is blended with the polyvinyl chloride and prevents inductive power. Accordingly, the antistatic agent can prevent static electricity generated between the carbon plate (110) and the waterproof sheet (130), ultimately preventing leakage current.

[0064] Additionally, the waterproof sheet may further include a plasticizer blended with polyvinyl chloride to enhance thermoplasticity. For example, the polyvinyl chloride may be blended at a ratio of approximately 100 kg, the plasticizer at approximately 50 kg, and the antistatic agent at approximately 2 kg. The components of the waterproof sheet blended at these ratios may be manufactured into sheet form, etc., through a calendar molding machine.

[0065] Furthermore, the carbon plate (110) may include a copper wire (111). The copper wire (111) may be arranged vertically on both sides of the inner surface of the heating unit.

[0066] The heating mat for road snow melting according to the present invention may further include a double-ended cut portion (not shown), a connector electrode (140), a wiring (153), a connector insulation portion (not shown), and a protector (170).

[0067] The double-ended cut portion is a portion where both ends of the carbon plate (110) are cut so that it is provided as a single unit, and the connector electrode (140) can be electrically connected to the copper wire (111) and can be exposed to the outside from the double-ended cut portion.

[0068] The wiring (153) can be electrically connected to the connector electrode (140). The connector insulation portion can be made of a material such as rubber, can insulate the connector electrode (140), and can be applied to a protector (170, for example, EPDM rubber) whose back surface is specially treated with an adhesive (173) so as to adhere to the connector electrode (140). Since adhesion is not good between the waterproof sheet (130) and the protector (170, EPDM rubber), a special chemical treatment can be used to resolve this problem, thereby performing adhesion and waterproofing.

[0069] The protector (170) can seal both ends with insulation.

[0070] Accordingly, it is possible to electrically insulate the connector electrode (140) through the connector electrode (140), and to electrically insulate the connector electrode (140) and other parts as well as seal the cut portion at both ends through the protector (170).

[0071] Additionally, the protector (170) may include a closing member (171), a wiring pass-through hole (172), and an adhesive (173). The closing member (171) may be made of an insulating material such as EPDM rubber and may have an insertion groove (171a) so that the connector insulation portion and the double-ended cut portions are inserted together.

[0072] The wiring pass-through hole (172) can penetrate the closing member (171) and allow wiring to pass through, and the space between the wiring pass-through hole (172) and the wiring can be sealed by a bushing member (174) or the like. At this time, the bushing member (174) can be made of a rubber material, but is not limited thereto.

[0073] The adhesive (173) can adhere the finishing member (171) to the waterproof sheet.

[0074] The sealing described above can be performed using low or high frequency, and the material can be rubber or silicone, so it is not limited to the above description.

[0075]

[0076] Hereinafter, examples and comparative examples of a heating mat for road snow melting according to the present invention will be described.

[0077] [Example]

[0078] In the example, a heating mat for road snow melting made of a mat-shaped carbon plate with a width of 530 mm was installed on the foundation floor, and then the floor was constructed with 50 mm of mortar.

[0079] [Comparative Example 1]

[0080] Comparative Example 1 was performed by installing three 12 mm diameter heating tubes (nichrome wire) 250 mm apart from each other on the foundation floor, corresponding to the 530 mm width of the road snow melting heating mat of the embodiment, and then constructing the floor with 50 mm of mortar. In other words, electric underfloor heating was installed.

[0081] [Comparative Example 2] In Comparative Example 2, three 20 mm diameter heating pipes (nichrome wire, water) were installed on the foundation floor at a distance of 250 mm from each other to correspond to the 530 mm width of the road snow melting heating mat of the example, and the floor was constructed with 50 mm of mortar. In other words, electric hot water pipe heating was constructed.

[0082] [Experimental Example]

[0083] Electricity was supplied to heating examples 1 and 2, and the heating performance and efficiency were compared. Specifically, preheating time, lifespan, water loss thickness, insulation layer issues, advice, and maintenance costs were measured. The results for the experimental examples are shown in [Table 1] below.

[0084] Classification Implementation Preliminary Comparative Example 1 Comparative Example 2 Preheating time 30~40 minutes 90~120 minutes 90~120 minutes Lifespan Semi-permanent 5~8 years (hot wire corrosion, coil fatigue and disconnection) 5~8 years (hot wire deposit hardening phenomenon, coil fatigue and disconnection, sealing plug problem) Mortar thickness 30~200mm possible (existing power consumption is the same as 180-200w regardless of mortar thickness) 30~60mm (Try to maintain existing power consumption of 400w by making mortar as thin as possible, increasing mortar thickness increases power consumption) 30~60mm Always use double wires for wires and moving wires to prevent freezing, power consumption increases due to always-on wire, existing 500w (1 wire cut off after initial 20~30 minutes of heating) Insulation layer problem Bubbles 60mm or more recommended, Isopink 50mm or more recommendedDue to heat of nichrome wire Insulation layer (foundation, isopink (self-sinking phenomenon occurs (heating efficiency reduced by more than 40%)) Insulation layer (foundation, isopink (self-sinking phenomenon occurs (heating efficiency reduced by more than 40%)) due to heat from nichrome wire Heating possible at a floor height of 20m or more due to far-infrared radiant heat, EHP, can be used as main heating without air conditioning heating Limited to main heating at floor heights of 3m or more with convection heating. EHP, air conditioning heating is required Convection heating is limited to main heating at floor heights of 3m or more with convection heating. EHP, air conditioning heating is required Maintenance cost Per pyeong / 5,000 won Per pyeong / 11,000 won Per pyeong / 12,000 won

[0085] As shown in [Table 1] above, the embodiment enables rapid heating in 30 to 40 minutes with 50 mm thick mortar. Since radiant heat is used, there are no floor height restrictions, so even buildings with floor heights exceeding 20 m can be heated using only floor heating.

[0086] In addition, the mortar thickness can be over 200 mm, and other finishing materials (stone, asphalt) can be used in addition to mortar, making it easy to use finishing materials.

[0087] And, since the heating element is made of a carbon plate rather than a carbon wire, heat is generated throughout the carbon plate, and it has a semi-permanent lifespan.

[0088] In addition, even in spaces larger than 2,000 pyeong, single heating is possible through the example without EHP or air conditioning, and construction costs can also be reduced.

[0089] And, the maintenance cost can be calculated as 5,000 won per pyeong, with power consumption of 180-200w / 3.3㎡, when operated for 8 hours per day for 30 days.

[0090] Meanwhile, a device for manufacturing a heating mat for road snow melting according to the present invention is described.

[0091] Referring to FIG. 5, a device for manufacturing a heating mat for road snow melting according to the present invention may include a support frame (210), an upper waterproof sheet supply drum (220), a lower waterproof sheet supply drum (230), a carbon plate supply drum (240), an upper shielding sheet supply drum (250), a lower shielding sheet supply drum (260), and a joint (270).

[0092] First, the support frame (210) is a structure equipped with each drum (220, 230, 240, 250, 260) and a joint (270) to be described later.

[0093] The upper waterproof sheet supply drum (220) is rotatably provided on one side of the support frame (210) and can continuously supply the upper waterproof sheet (131).

[0094] The lower waterproof sheet supply drum (230) is rotatably provided on the other side of the support frame (210) and can continuously supply the lower waterproof sheet (132).

[0095] The carbon plate supply drum (240) is rotatably provided between one side and the other side of the support frame (210) and can continuously supply carbon plates (110).

[0096] The upper shielding sheet supply drum (250) is provided on the support frame (210), and is provided between the upper waterproof sheet supply drum (220) and the carbon plate supply drum (240) so as to continuously supply the upper shielding sheet (121).

[0097] The lower shielding sheet supply drum (260) is provided on the support frame (210), and is provided between the lower waterproof sheet supply drum (230) and the carbon plate supply drum (240) to continuously supply the lower shielding sheet (122).

[0098] The joint (270) is provided on the support frame (210) and is supplied from each drum. The upper waterproof sheet (131), the upper shielding sheet (121), the carbon plate (110), the lower shielding sheet (122) and the lower waterproof sheet (132) are laminated and bonded while applying pressure, thereby enabling the heating mat for road snow melting to be continuously drawn out.

[0099] At this time, a carbon plate (110) closely bonded to a waterproof sheet (130) can be continuously supplied, and the formation of an air layer between the carbon plate (110) and the waterproof sheet (130) can be minimized through close bonding.

[0100] Meanwhile, the joint (270) can be laminated twice.

[0101] First, the first bonding roller unit (271) can bond the upper waterproof sheet (131), the upper shielding sheet (121), the carbon plate (110), and the lower shielding sheet (122) sequentially by applying pressure.

[0102] In addition, the second bonding roller unit (272) can bond the lower waterproof sheet (132) while applying pressure to the lower portion of the lower shielding sheet (122) that has passed through the first bonding roller unit (271).

[0103] The above-described bonding roller (273) section is composed of a pair of bonding rollers (273), and a heater may be provided on at least one of the bonding rollers (273).

[0104] That is, the upper waterproof sheet (131), the upper shielding sheet (121), the carbon plate (110) and the lower shielding sheet (122) are sequentially laminated and passed through the first bonding roller section (271) consisting of a pair of bonding rollers (273), so that the upper waterproof sheet (131) is laminated to the upper shielding sheet (121) and the carbon plate (110) while the lower shielding sheet (122) is laminated at the same time.

[0105] And, while the lower waterproof sheet (132) is laminated on the lower portion of the lower shielding sheet (122) that has passed through the first bonding roller section (271), the lower waterproof sheet (132) is laminated to the carbon plate (110) while passing through the second bonding roller section (272) composed of a pair of bonding rollers (273).

[0106] At this time, if the shielding sheet (120) has a mesh structure, the waterproof sheet (130), the shielding sheet (120), and the carbon plate (110) may be laminated to each other. However, if the shielding sheet (120) has a thin film structure, the waterproof sheet (130) and the shielding sheet (120) may be laminated, and it may be preferable to apply an adhesive sample between the carbon plate (110) and the shielding sheet (120).

[0107] To this end, the joint (270) may further include a first adhesive sample application nozzle that is provided at the front end of the first laminating roller (281) that laminates the upper shielding sheet (121) and the carbon plate (110) and pulls them out to the second laminating roller (282) and applies an adhesive sample that can adhere the upper shielding sheet (121) and the carbon plate (110) to each other.

[0108] In addition, the joint portion (270) may further include a second adhesive sample application nozzle provided at the front end of the second joint roller portion (272) that laminates the lower shielding sheet (122) and the carbon plate (110) and applies an adhesive sample that can adhere the lower shielding sheet (122) and the carbon plate (110) to each other.

[0109]

[0110] *Here, the first bonding roller unit (271) can pressurize the state in which the upper waterproof sheet (131), the upper shielding sheet (121), and the carbon plate (110) are sequentially laminated. Then, it is necessary to additionally install a laminating roller unit (280) that can laminate and withdraw the lower shielding sheet (122) under the carbon plate (110) that has passed through the first bonding roller unit (271).

[0111] That is, by passing the upper waterproof sheet (131), the upper shielding sheet (121), the carbon plate (110), and the lower shielding sheet (122) through the first bonding roller unit (271), the upper waterproof sheet (131), the upper shielding sheet (121), and the carbon plate (110) are laminated, and the lower shielding sheet (122) can be taken out in a laminated state on the carbon plate (110) without the laminating roller unit (280) and supplied to the second bonding roller unit (272).

[0112] In addition, through two laminating processes, the layers can be firmly bonded together to ensure a secure and close bond, so that a heating mat (100) for road snow melting can be manufactured with a solid and stable structure.

[0113] In addition, in the production of a heating mat (100) for road snow melting, it is possible to reduce the defect rate and produce products of consistent quality.

[0114] Meanwhile, the joint (270) may include a first laminating roller (281) that laminates an upper shielding sheet (121) and a carbon plate (110) and pulls them out to a second laminating roller (282), and a second laminating roller (282) that laminates an upper waterproof sheet (131) on the outside of the upper shielding sheet (121) pulled out from the first laminating roller (281) and pulls them out to the first jointing roller section (271).

[0115] This laminated roller unit (280) allows each layer to be positioned accurately. This maintains precise alignment between layers, thereby enhancing the sense of unity of the overall structure. Furthermore, the laminated roller unit (280) maintains the thickness of each layer uniformly, thereby maintaining the consistent quality of the road snow melting heating mat (100).

[0116] Due to this, the laminating roller unit (280) can automate the manufacturing process, thereby increasing production speed and reducing dependence on manpower, thereby improving productivity. Furthermore, the laminating roller unit (280) can evenly press each layer by continuously laminating and then drawing out each layer, thereby increasing interlayer adhesion.

[0117] That is, by aligning each layer through the laminating roller unit (280) and laminating it with uniform pressure, the durability of the heating mat (100) for road snow melting is increased, and its performance can be maintained even during long-term use. In addition, by preventing air from being included in the laminating process, the bonding and bonding strength between layers can be increased.

[0118] Meanwhile, the joint part (270) is provided between the first laminating roller (281) and the upper shielding sheet supply drum (250), and includes a first pressing roller (291) that presses and flattens the upper shielding sheet (121) supplied to the first laminating roller (281), a second pressing roller (292) that is provided between the second laminating roller (282) and the upper waterproofing sheet supply drum (220), and presses and flattens the upper waterproofing sheet (131) supplied to the second laminating roller (282), a third pressing roller (293) that is provided between the first bonding roller unit (271) and the lower shielding sheet supply drum (260), and presses and flattens the lower shielding sheet (122) supplied to the first bonding roller unit (271), and a second bonding roller unit (272) and the lower waterproofing sheet supply drum (230). It may further include a fourth pressing roller (294) that presses and flattens the lower waterproof sheet (132) supplied to the second joining roller section (272).

[0119] Here, the compression roller section (290) is installed with a pair of rollers facing each other, and the shielding sheet (120) and the waterproof sheet (130) pass between the pair of rollers and are compressed.

[0120] By making each layer flat through a number of compression roller units (290) and ensuring high consistency and bonding strength during the stacking and laminating process, a high-quality, high-durability, and high-reliability road snow melting heating mat (100) can be produced.

[0121] Meanwhile, the manufacturing device for a heating mat for road snow melting according to the present invention may further include a reflective sheet supply drum provided between the lower waterproof sheet supply drum (230) and the carbon plate supply drum (240) to continuously supply a reflective sheet to the second bonding roller unit (272), and to supply the reflective sheet between the lower shielding sheet (122) that has passed through the first bonding roller unit (271) and the lower waterproof sheet (132). In addition, the device may further include a third adhesive sample application nozzle that can apply an adhesive sample between the lower shielding sheet (122) and the reflective sheet to bond them to each other, but is not limited thereto.
