Abstract
본 발명은 부틸고무 재질에 의한 점착층(110); 열선의 직조에 의해 형성된 발열체(120); 탄소섬유(Carbon Fiber)를 그리드 형태로 가공한 카본그리드(Carbon Grid)(130); 포장작업에 의한 상기 발열체(120) 및 카본그리드(130)의 손상을 방지하도록, 최상부에 적층된 고밀도 폴리에틸렌 필름(HDPE Film)(140);을 포함하고, 상기 점착층(110)은 상기 발열체(120), 카본그리드(130), 고밀도 폴리에틸렌 필름(140)을 상호 접착하도록 형성됨과 아울러, 노면 또는 교면에 부착하도록 최하층에 형성된 것을 특징으로 하는 도로포장용 발열시트(100)를 제시함으로써, 열전도성 및 보온기능이 우수할 뿐만 아니라, 아스팔트의 포설 및 다짐 시 발생하는 하중에 의한 시트의 손상을 방지하고, 아스콘의 소성변형에 대한 저항성을 증대할 수 있도록 한다.The present invention includes an adhesive layer 110 made of butyl rubber; A heating element 120 formed by weaving hot wires; Carbon grid (130) made by processing carbon fiber into a grid shape; To prevent damage to the heating element 120 and the carbon grid 130 due to packaging operations, a high-density polyethylene film (HDPE Film) 140 is laminated on the top, and the adhesive layer 110 is formed on the heating element ( 120), a carbon grid 130, and a high-density polyethylene film 140 are formed to adhere to each other, and a heating sheet 100 for road paving is provided, which is characterized in that it is formed in the lowest layer to be attached to the road surface or bridge surface, thereby providing thermal conductivity and Not only does it have an excellent thermal insulation function, but it also prevents damage to the sheet due to the load that occurs when laying and compacting asphalt, and increases the resistance to plastic deformation of asphalt.
Description
본 발명은 건설 기술분야에 관한 것으로서, 상세하게는 도로포장용 발열시트(100) 및 이를 이용한 도로포장공법에 관한 것이다.The present invention relates to the field of construction technology, and more specifically, to a heating sheet 100 for road paving and a road paving method using the same.
도 1은 한국등록특허 제10-2350803호(전기발열 자착식 방수시트 및 이를 이용한 방수 및/또는 블랙아이스 방지공법)의 도면이다.Figure 1 is a drawing of Korean Patent No. 10-2350803 (electrically heated self-adhesive waterproof sheet and waterproofing and/or black ice prevention method using the same).
이는 이형지(10); 상기 이형지(10) 상에 구비된 제1 카본그라파이트 부틸고무층(20); 상기 제1 카본그라파이트 부틸고무층(20) 상에 구비된 카본열선층(30); 상기 카본열선층(30) 상에 구비된 제2 카본그라파이트 부틸고무층(40); 및 상기 제2 카본그라파이트 부틸고무층(40) 상에 구비된 합성필름층(50);을 포함하여 구성된다.These include Hyeongji Lee (10); A first carbon graphite butyl rubber layer (20) provided on the release paper (10); A carbon heating wire layer (30) provided on the first carbon graphite butyl rubber layer (20); A second carbon graphite butyl rubber layer (40) provided on the carbon heating layer (30); and a synthetic film layer 50 provided on the second carbon graphite butyl rubber layer 40.
카본열선층(30)은 직조된 카본 발열체(120) 원단 등에 의해 이루어진다.The carbon heating layer 30 is made of a woven carbon heating element 120 fabric.
카본그라파이트 부틸고무층(20,40)은 단열과 발열, 방수성능을 발휘하는 재료로서, 카본열선층(30)의 상하에 적층된다.The carbon graphite butyl rubber layers (20, 40) are materials that provide insulation, heat generation, and waterproofing properties, and are laminated above and below the carbon heating wire layer (30).
합성필름층(50)은 카본그라파이트 부틸고무층(20,40)과 카본열선층(30)을 보호하기 위한 것으로서, 폴리에틸렌테레프탈레이트(PET) 등에 의해 이루어진다.The synthetic film layer 50 is intended to protect the carbon graphite butyl rubber layers 20 and 40 and the carbon heating layer 30, and is made of polyethylene terephthalate (PET), etc.
이는 포트홀이 발생하더라도 포트홀 부분만 기능이 손상되고, 미손상 부위는 제기능을 함으로써 블랙아이스 현상을 방지할 수 있고, 기존 열선은 외부로 열을 많이 빼앗겨 전력 손실이 많았으나 단열 성능을 가짐으로써 하부로부터 열 소모를 방지하고, 상부로 열을 방출시켜 전력소모를 최소화할 수 있는 이점이 있다.This prevents the black ice phenomenon by ensuring that even if a pothole occurs, only the porthole part is damaged and the undamaged part continues to function properly. The existing heating wire lost a lot of heat to the outside and caused a lot of power loss, but by having insulation performance, it can prevent the black ice phenomenon. It has the advantage of preventing heat consumption from the top and minimizing power consumption by dissipating heat to the top.

첫째, 종래기술에 의한 방수시트는 도로포장의 기층(보조기층)과 표층의 사이에 매설되는데, 기층(보조기층)의 상부에 방수시트가 부착된 상태에서 표층의 형성을 위한 아스팔트의 포설 및 다짐 시 방수시트의 카본열선층(30)의 손상이 발생하기 쉽다.First, the waterproof sheet according to the prior art is buried between the base layer (sub-base layer) and the surface layer of the road pavement. With the waterproof sheet attached to the top of the base layer (sub-base layer), asphalt is laid and compacted to form the surface layer. It is easy for the carbon heating layer 30 of the waterproof sheet to be damaged.
카본열선층(30)의 상하에 적층되는 카본그라파이트 부틸고무층(20,40)은 아스팔트의 포설 및 다짐 시 발생하는 하중으로부터 카본열선층(30)을 보호하기 어렵다.It is difficult for the carbon graphite butyl rubber layers 20 and 40 laminated above and below the carbon heating layer 30 to protect the carbon heating layer 30 from the load generated when laying and compacting asphalt.
둘째, 합성필름층(50)에 사용되는 폴리에틸렌테레프탈레이트(PET)는 용융점이 너무 높으므로, 그 위에 시공되는 아스콘이 고온 상태를 반드시 유지해야 하고, 그렇지 않은 경우 아스콘과 합성필름층(50)의 부착강도가 낮아 반사균열 발생의 이유가 된다.Second, the polyethylene terephthalate (PET) used in the synthetic film layer 50 has a too high melting point, so the asphalt concrete constructed thereon must be maintained at a high temperature. Otherwise, the asphalt concrete and the synthetic film layer 50 must be maintained at a high temperature. Low adhesion strength causes reflection cracks.
위 종래기술의 도면부호는 당해 종래기술의 설명에 대하여만 한정되는 것으로 한다.The drawing symbols of the above prior art are limited only to the description of the prior art.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2 이하에 도시된 바와 같이, 본 발명에 의한 도로포장용 발열시트(100)는 기본적으로, 점착층(110); 발열체(120); 카본그리드(Carbon Grid)(130); 고밀도 폴리에틸렌 필름(HDPE Film)(140);을 포함하여 구성된다.As shown in Figure 2 and below, the heating sheet 100 for road pavement according to the present invention basically includes an adhesive layer 110; Heating element 120; Carbon Grid (130); It consists of a high-density polyethylene film (HDPE Film) 140.
점착층(110)은 부틸고무 재질에 의해 형성되며, 구체적으로 부틸고무 10~25중량%; 무기질 필러 35~60중량%; 점착부여제 15~25 중량%; 개질제 5~20중량%; 안료 0.1~3중량%; 첨가제 0.1~3중량%;를 포함하여 구성된다.The adhesive layer 110 is formed of butyl rubber, specifically 10 to 25% by weight of butyl rubber; 35 to 60% by weight of inorganic filler; 15-25% by weight of tackifier; 5-20% by weight of modifier; Pigment 0.1~3% by weight; Contains 0.1 to 3% by weight of additives.
부틸고무는 범용적으로 공장에서 생산되는 합성고무의 한 종류로서, 점착성이 우수하고 내열 및 내한성이 우수하다. Butyl rubber is a type of synthetic rubber produced in factories for general purposes and has excellent adhesion and heat and cold resistance.
부틸성분이 10%중량 미만인 경우, 그 사용량이 너무 적어 탄성 및 신장률 등의 물성이 저하되고 부틸고무 특유의 충전 특성이 충분히 발휘되지 않는 등의 문제가 있으며, 25%중량을 초과하는 경우 필요 이상의 사용으로 가격경쟁력이 낮아진다.If the butyl component is less than 10% by weight, the amount used is too small, which causes problems such as lowering physical properties such as elasticity and elongation, and the unique filling characteristics of butyl rubber are not fully demonstrated. If it exceeds 25% by weight, it is used more than necessary. This reduces price competitiveness.
무기질 필러는 탄산칼슘, 탈크, 실리카, 마이카, 클레이, 플라이애쉬, 벤토나이트 중 하나 또는 2 이상의 혼합에 의해 형성된다.The inorganic filler is formed by one or a mixture of two or more of calcium carbonate, talc, silica, mica, clay, fly ash, and bentonite.
무기질 필러 성분이 35중량% 미만이 되면 제품의 압축강도가 저하되고, 60중량%를 초과하면 사용량이 너무 많아 제품의 탄성, 신장률, 점착강도 등의 물성을 저해하는 요인이 된다.If the inorganic filler component is less than 35% by weight, the compressive strength of the product decreases, and if it exceeds 60% by weight, the amount used is too large, which deteriorates the physical properties such as elasticity, elongation, and adhesive strength of the product.
점착부여제는 석유수지, 폴리부텐, 로진(송진) 및 로진에스테르 중 하나 또는 2 이상의 혼합에 의해 형성된다.The tackifier is formed by mixing one or more of petroleum resin, polybutene, rosin, and rosin ester.
석유수지는 C5계,C9계, 공중합수지, 수첨수지 등이 있으며 단독 또는 2종 이상 조합하여 사용할 수 있다. Petroleum resins include C5-based, C9-based, copolymer resins, and hydrogenated resins, and can be used alone or in combination of two or more types.
점착부여제가 15중량% 미만이 되면 점착제로서의 기능이 저하되고, 25중량%를 초과하면 필요 이상의 사용으로 가격경쟁력이 낮아진다.If the tackifier is less than 15% by weight, its function as an adhesive deteriorates, and if it exceeds 25% by weight, price competitiveness is lowered due to excessive use.
개질제는 천연고무(NR), 에스비에스고무(SBS), 클리로프렌고무(CR), 이피디엠고무(EPDM), 에스비알고무(SBR), 에틸렌비닐아세테이트(EVA), 아타티폴리프로필렌(APP), 비정형폴리올레핀(APAO), 폴리에틸렌(PE), 폴리프로필렌(PP) 중 하나 또는 2 이상의 혼합에 의해 형성된다.Modifiers include natural rubber (NR), SBS rubber (SBS), chloroprene rubber (CR), EPDM rubber (EPDM), SBR rubber (SBR), ethylene vinyl acetate (EVA), and atathipolypropylene (APP). It is formed by one or a mixture of two or more of amorphous polyolefin (APAO), polyethylene (PE), and polypropylene (PP).
개질제가 5중량% 미만이 되면 사용량이 너무 적어 개질효과가 낮으며, 20중량%를 초과하면 사용량이 너무 많아 가격상승의 요인이 된다.If the amount of modifier is less than 5% by weight, the amount used is too small and the reforming effect is low, and if it exceeds 20% by weight, the amount used is too much, which causes a rise in price.
안료는 무기안료, 각 색상별 유기안료 중 하나 또는 이들의 혼합에 의해 형성된 것이 바람직하다. The pigment is preferably formed by one of inorganic pigments, organic pigments for each color, or a mixture thereof.
무기안료는 카본블랙, 이산화티탄(백색), 적색 산화철, 황색 산화철, 산화철 중 하나 또는 2 이상의 혼합에 의해 형성된 것이 바람직하다. The inorganic pigment is preferably formed by one or a mixture of two or more of carbon black, titanium dioxide (white), red iron oxide, yellow iron oxide, and iron oxide.
단, 납, 수은, 크롬 등의 중금속이 포함되어 제조된 안료는 사용하여서는 않된다. However, pigments manufactured containing heavy metals such as lead, mercury, and chromium should not be used.
그 사용량이 0.1중량% 미만이 되면 사용량이 너무 적어 원하는 색상의 제품을 기대하기 어렵고, 3중량%를 초과하면 과잉사용으로 가격경쟁력이 낮아진다.If the amount used is less than 0.1% by weight, it is difficult to expect a product of the desired color because the amount used is too small, and if it exceeds 3% by weight, price competitiveness is lowered due to excessive use.
첨가제로는 내열안정제, 자외선안정제, 광택제, 활제 등이 있으며, 그 사용량은 0.1~3% 중량이 적정하다.Additives include heat stabilizers, UV stabilizers, brighteners, and lubricants, and the appropriate amount of use is 0.1 to 3% by weight.
위와 같은 구성을 취하는 점착층(110)은 점착력이 우수함은 물론, 시공 편리성, 내구성 및 방수성능이 우수할 뿐만 아니라, 부착성능과 수밀성, 균열 충진성 성능이 우수하다.The adhesive layer 110 having the above configuration not only has excellent adhesion, ease of construction, durability, and waterproof performance, but also excellent adhesion performance, water tightness, and crack filling performance.
이러한 점착층(110)은 발열체(120), 카본그리드(130), 고밀도 폴리에틸렌 필름(140)을 상호 접착하도록 형성됨과 아울러, 노면 또는 교면에 부착하도록 최하층에 형성된다.This adhesive layer 110 is formed to adhere the heating element 120, the carbon grid 130, and the high-density polyethylene film 140 to each other, and is also formed at the bottom layer to adhere to the road surface or bridge surface.
표 1은 본 발명에 의한 발열시트(100)에 사용되는 점착층(110)의 물성을 입증하기 위한 실시예 1~3의 배합에 관한 것이다.Table 1 relates to the formulations of Examples 1 to 3 to demonstrate the physical properties of the adhesive layer 110 used in the heating sheet 100 according to the present invention.
표 2는 상술한 점착층(110)의 실시예 1~3의 물성 시험결과에 관한 것이다.Table 2 relates to the physical property test results of Examples 1 to 3 of the adhesive layer 110 described above.
본 발명에 사용되는 점착층(110)의 실시예 1~3은 모두 비교예(일반 아스팔트 제품)에 비해 내열성과 내한성이 우수한 것으로 나타났다.Examples 1 to 3 of the adhesive layer 110 used in the present invention were all found to have superior heat resistance and cold resistance compared to the comparative example (general asphalt product).
점착력, 접합강도 등의 성능 측면에서 볼 때, 실시예 3이 가장 우수한 것으로 판단된다.In terms of performance such as adhesion and bonding strength, Example 3 is judged to be the best.
발열체(120)는 카본 발열선과 같은 열선의 직조(위사와 경사가 직조된 구조)에 의해 형성되는데, 전원 연결부가 연결되어 전원의 공급으로 발열이 이루어지도록 함으로써 결빙을 방지한다. The heating element 120 is formed by weaving (a structure in which weft and warp threads are woven) a heating wire such as a carbon heating wire, and a power connection is connected to generate heat by supplying power to prevent freezing.
발열선은 전도성 재료(카본나노분말, 그라파이트, 탄소분말 등)에 의해 형성되고, 용융수지를 코팅하여 사용할 수 있으며, 발열선을 보호하는 폴리에스터 섬유(Polyester Fiber)가 함께 직조된 구조로 발열체를 성형하는 것이 바람직하다.The heating wire is formed of conductive materials (carbon nanopowder, graphite, carbon powder, etc.) and can be used by coating it with molten resin. The heating element is formed with a structure in which polyester fibers that protect the heating wire are woven together. It is desirable.
카본그리드(Carbon Grid)(130)는 탄소섬유(Carbon Fiber)를 그리드 형태로 가공한 것이다.Carbon grid 130 is carbon fiber processed into a grid shape.
카본(Carbon)과 그라파이트(Carbon Graphite)는 공업적으로 석유화학공업 부산물인 피치나 합성섬유 레이온을 이용해 만드는 법도 있지만, 오늘날 거의 모든 탄소섬유는 대게 폴리아크릴로니트릴(Polyacrylonitrile, PAN)이라는 탄소화합물을 가열해서 만든다. Carbon and graphite can be made industrially using pitch, a by-product of the petrochemical industry, or synthetic fiber rayon, but today, almost all carbon fibers are made from a carbon compound called polyacrylonitrile (PAN). It is made by heating.
카본은 1000~1500℃ 온도의 소성로에서 열처리 과정을 통해 만들어지며, 생성된 비정질 구조의 카본을 전기저항로에서 2500~3000℃의 고열로 재처리하여 결정구조를 갖는 그라파이트가 만들어진다.Carbon is made through a heat treatment process in a firing furnace at a temperature of 1000~1500℃, and the carbon with an amorphous structure is reprocessed at a high temperature of 2500~3000℃ in an electric resistance furnace to create graphite with a crystalline structure.
이렇게 만들어진 카본과 그라파이트는 기계적 특성 및 용융분야에서 요구되어는 용도 및 그 특성에 따라 구분되어 사용된다.Carbon and graphite produced in this way are used separately according to their mechanical properties, applications required in the melting field, and their characteristics.
카본그리드(Carbon Grid)는 탄소섬유(Carbon Fiber)를 그리드 형태로 가공한 소재로서, 발열 점착 시트를 보강하여 아스콘 포설시 발열 점착 시트의 파손을 방지하는 보강 기능과, 아스콘의 소성변형에 대한 저항기능을 수행한다.Carbon Grid is a material made by processing carbon fiber into a grid shape. It has a reinforcing function to prevent damage to the heat-generating adhesive sheet when laying asphalt concrete by reinforcing the heat-generating adhesive sheet, and resistance to plastic deformation of the asphalt concrete. performs its function.
또한, 열전도성이 우수하므로, 발열체에서 발생한 열을 표층의 아스콘에 빠르게 전달하는 열전달 기능과, 발열온도를 유지하는 보온 기능을 수행한다.In addition, because it has excellent thermal conductivity, it performs a heat transfer function that quickly transfers heat generated from the heating element to the surface layer of asphalt concrete and a thermal insulation function that maintains the heating temperature.
고밀도 폴리에틸렌 필름(HDPE Film)(140)은 포장작업에 의한 발열체(120) 및 카본그리드(130)의 손상을 방지하도록, 최상부에 적층된다.High-density polyethylene film (HDPE Film) 140 is laminated on the top to prevent damage to the heating element 120 and carbon grid 130 due to packaging operations.
이는 상술한 종래기술에 의한 발열(방수)시트에 사용되는 폴리에틸렌테레프탈레이트(PET) 필름에 비해, 용융점(121~122℃)이 낮아 일반적으로 포설되는 아스콘의 온도(120~140℃)에서 고밀도 폴리에틸렌 필름(HDPE Film)(140)의 용융에 의해 발열시트(100)와 아스콘의 열융착이 이루어지므로 부착성(밀착성)이 우수하다는 장점이 있다.Compared to the polyethylene terephthalate (PET) film used in the heating (waterproofing) sheet according to the above-described prior art, this has a lower melting point (121-122°C), so it is a high-density polyethylene film at the temperature of generally installed asphalt concrete (120-140°C). By melting the film (HDPE Film) (140) Since the heating sheet 100 and asphalt concrete are heat fused, there is an advantage of excellent adhesion (adhesion).
또한, 고밀도 폴리에틸렌 필름(HDPE Film)(140)은 폴리에틸렌테레프탈레이트(PET) 필름에 비해, 신장률과 인열성능이 우수하므로, 아스콘의 다짐 시 골재에 의한 발열시트(100)의 손상을 방지할 수 있다.In addition, the high-density polyethylene film (HDPE Film) 140 has superior elongation and tear performance compared to polyethylene terephthalate (PET) film, so it can prevent damage to the heating sheet 100 caused by aggregate when compacting asphalt concrete. .
표 3은 본 발명에 의한 발열시트(100)에 사용되는 고밀도 폴리에틸렌 필름(HDPE Film)(140)의 물성을 입증하기 위한 실시예 1~3의 두께에 관한 것이다.Table 3 relates to the thickness of Examples 1 to 3 to demonstrate the physical properties of the high-density polyethylene film (HDPE Film) 140 used in the heating sheet 100 according to the present invention.
표 4는 상술한 고밀도 폴리에틸렌 필름(HDPE Film)(140)의 실시예 1~3의 물성 시험결과에 관한 것이다.Table 4 relates to the physical property test results of Examples 1 to 3 of the above-described high-density polyethylene film (HDPE Film) 140.
비교예(폴리에틸렌테레프탈레이트(PET) 필름)의 경우, 용융점(252℃)이 너무 높아 일반적으로 포설되는 아스콘의 온도(120~140℃)에서 발열시트(100)와 아스콘의 열융착이 이루어지지 않으므로 부착성(밀착성)이 낮아 반사균열의 발생 우려가 크다.In the case of the comparative example (polyethylene terephthalate (PET) film), the melting point (252°C) is so high that thermal fusion of the heating sheet 100 and asphalt concrete does not occur at the temperature of asphalt concrete (120 to 140°C) that is generally installed. Due to low adhesion, there is a high risk of reflection cracks occurring.
이에 비해, 본 발명의 실시예(고밀도 폴리에틸렌 필름(HDPE Film)(140))의 경우, 용융점(121~122℃)이 낮아 일반적으로 포설되는 아스콘의 온도(120~140℃)에서 발열시트(100)와 아스콘의 열융착이 이루어지므로 부착성(밀착성)이 우수하므로, 반사균열의 발생 우려가 작다는 장점이 있다.In contrast, in the case of the embodiment of the present invention (high-density polyethylene film (HDPE Film) 140), the melting point (121 ~ 122 ℃) is low, so the heating sheet (100) is used at the temperature of generally installed asphalt concrete (120 ~ 140 ℃). ) and asphalt are heat fused, so adhesion (adhesion) is excellent, so there is an advantage that there is less risk of reflection cracks.
또한, 비교예(폴리에틸렌테레프탈레이트(PET) 필름)의 경우, 인장강도는 우수하지만, 신장률 및 인열강도가 낮으므로, 아스콘 다짐 시 골재로 인한 시트의 파손 우려가 크다.In addition, in the case of the comparative example (polyethylene terephthalate (PET) film), the tensile strength is excellent, but the elongation and tear strength are low, so there is a high risk of damage to the sheet due to the aggregate when asphalt concrete is compacted.
이에 비해, 본 발명의 실시예(고밀도 폴리에틸렌 필름(HDPE Film)(140))의 경우, 신장률과 인열성능이 비교예에 비해 월등히 우수하므로, 아스콘의 다짐 시 골재에 의한 발열시트(100)의 손상을 방지할 수 있다.In contrast, in the case of the example of the present invention (high-density polyethylene film (HDPE Film) 140), the elongation and tear performance are significantly superior to the comparative example, so the heating sheet 100 is damaged by the aggregate during compaction of asphalt concrete. can be prevented.
