Description
본 발명은 열선 자체의 온도 과승을 방지하도록 형성되는 피티씨(PTC) 발열선을 제조함에 있어서, 심선(제1열선)과 바깥선(제2열선)이 고온으로 발열하더라도 카본폴리머의 내외측에 증착 또는 혼합된 카본이 고밀도의 브리지로 이어지거나 제1,2열선과 직접식으로 접촉되도록 형성되어 종전 대비 전도성이 개선되도록 함은 물론 고온에서의 열선 자체가 과승(카본폴리머의 팽창)하더라도 상기 열선들의 안정적인 발열을 유도할 수 있도록 한 것을 특징으로 하는 피티씨(PTC) 발열선의 제조방법에 관한 것이다.In the present invention, in manufacturing a PTC heating line formed to prevent the temperature rise of the heating wire itself, the core wire (first heating wire) and the outer wire (second heating wire) are deposited on the inside and outside of the carbon polymer even when the heat is generated at a high temperature. Alternatively, the mixed carbon is formed to lead to a high-density bridge or to be in direct contact with the first and second heating wires, thereby improving conductivity as compared to the past, and even if the heating wire itself is heated at a high temperature (expansion of the carbon polymer). It relates to a method for producing a PTC heating line, characterized in that to induce a stable heat generation.
일반적으로 전기를 이용하는 매트에 대한 발열선은 여러가지가 있으나, 최근에는 PTC(Positive Temperature Controll) 발열선을 이용하여 발열선 자체의 온도 과승을 방지하면서 발열을 도모하도록 형성된다.In general, there are various heating wires for the mat using electricity, but recently, a PTC (Positive Temperature Controll) heating wire is used to prevent the temperature rise of the heating wire itself and to form heat.
즉, 카본폴리머를 이용한 발열선은 별도로 온도 감지센서와 온도과열 방지장 치가 불필요하고 감온성 절연수지(카본폴리머) 자체가 절연체로 활용되면서, 발열선과 감지선이 하나의 케이블 내에 배치할 수 있으므로 비용이 저렴하고 작업성이 좋으며, 모든 부위에 걸쳐서 국부 과열시에 감지능력이 탁월하므로 많이 사용이 되고 있다.In other words, the heating wire using carbon polymer is unnecessary because the temperature sensor and temperature overheating prevention device are not necessary, and the thermosensitive insulating resin (carbon polymer) itself is used as the insulator, so that the heating wire and the sensing wire can be arranged in one cable, so it is inexpensive. It is used frequently because it has excellent sensing ability in case of local overheating in all parts.
그러나, 이러한 종래의 PTC(Positive Temperature Controll) 발열선은 제조상 합성수지가 대략 70%혼합되고, 카본분말이 대략 30%혼합되어 카본이 충분한 전도성을 갖기에 밀도가 다소 떨어지며, 특히 이러한 구조의 PTC발열선은 바깥선이 카본폴리머에 권선시 카본과 소정 간격으로 불규칙하게 이격되어 심선과의 전기적인 연결에 의해 전원공급(통전)시 스파크를 발생시켜 화재의 위험을 야기시키는 원인이 되고 있다.However, such a conventional PTC (Positive Temperature Controll) heating wire is manufactured by mixing about 70% of synthetic resin and about 30% of carbon powder in manufacturing, so that carbon has sufficient conductivity. When the wire is wound on the carbon polymer, it is irregularly spaced at a predetermined interval from the carbon, causing sparks during power supply (power supply) by electrical connection with the core wire, causing a risk of fire.
또한, 종래의 PTC발열선은 상술한 구조(카본폴리머의 카본 저밀도 구조)로 형성되다 보니, 열선의 고온 발열시 카본폴리머가 팽창하여 카본과 카본간 간격이 서로 이격되어 원활한 과승방지 제어가 곤란한 문제가 발생되고 있다.(도 2의 종전기술 참조)In addition, since the conventional PTC heating wire is formed with the above-described structure (carbon low density structure of carbon polymer), the carbon polymer expands when the heating wire is heated at high temperature, and the gap between carbon and carbon is spaced apart from each other, making it difficult to prevent smooth overheating control. (See the prior art in FIG. 2).
본 발명은 상술한 문제점을 해결하기 위한 것으로, 그 기술적 요지는 열선 자체의 온도 과승을 방지하도록 형성되는 피티씨(PTC) 발열선을 제조함에 있어서, 심선(제1열선)과 바깥선(제2열선)이 고온으로 발열하더라도 카본폴리머의 내외측에 증착 또는 혼합된 카본이 고밀도의 브리지로 이어지거나 제1,2열선과 직접식으로 접촉되도록 형성되어 종전 대비 전도성이 개선되도록 함은 물론 고온에서의 열선 자체가 과승(카본폴리머의 팽창)하더라도 상기 열선들의 안정적인 발열을 유도할 수 있도록 한 것을 특징으로 하는 피티씨(PTC) 발열선의 제조방법을 제공함에 그 목적이 있다.The present invention is to solve the above problems, the technical gist of the heating wire itself is formed in order to prevent the temperature rise of the PTC (PTC) heating wire, the core wire (first heating wire) and the outer wire (second heating wire ) Is heated to a high temperature, the carbon deposited or mixed on the inside and outside of the carbon polymer is formed to lead to a high-density bridge or in direct contact with the first and second heating wires to improve the conductivity compared to the previous, as well as hot wires at high temperatures It is an object of the present invention to provide a method for manufacturing a PTC heating element, which is characterized in that it is possible to induce stable heating of the heating wires even if the heating itself (expansion of the carbon polymer).

이때, 상기 카본폴리머 공급공정(S300)의 카본분말은 전기저항이 높은 것을 사용하여 카본폴리머가 발열에 의해 팽창함으로써 카본과 카본간 전도성이 저하되어 전류공급을 격감시켜 PTC기능을 수행하고, 상기 제1카본 분말공급 공정(S200), 제2카본 분말공급 공정(S400) 및 제3카본 분말공급 공정(S700)의 카본분말은 전기저항이 낮은 것을 사용하여 전도성이 원활하도록 형성되는 것이 바람직하다.At this time, the carbon powder of the carbon polymer supplying step (S300) uses a high electrical resistance, and the carbon polymer expands due to heat generation, thereby lowering the conductivity between carbon and carbon, thereby reducing the current supply to perform a PTC function, and Carbon powder of the first carbon powder supply process (S200), the second carbon powder supply process (S400), and the third carbon powder supply process (S700) is preferably formed to have good conductivity by using a low electrical resistance.
또한, 상기 제1카본 분말공급 공정(S200)과, 제2카본 분말공급 공정(S400)은 카본분말 대신 전도성이 우수한 동 분말, 황동 분말, 알루미늄 분말을 포함한 비철금속 분말 중 어느 하나를 사용하여 제1,2열선과 카본폴리머 간의 접촉저항을 최소화하도록 하는 것이 바람직하다.In addition, the first carbon powder supply process (S200) and the second carbon powder supply process (S400), the first carbon powder using any one of non-ferrous metal powder, including copper powder, brass powder, aluminum powder with excellent conductivity, instead of It is desirable to minimize the contact resistance between the heating element and the carbon polymer.
이와 같이, 본 발명은 피티씨(PTC) 발열선을 제조함에 있어서, 심선(제1열선)과 바깥선(제2열선)이 고온으로 발열하더라도 카본폴리머의 내외측에 증착 또는 혼합된 카본이 고밀도의 브리지로 이어지거나 제1,2열선과 직접식으로 접촉되도록 형성되어 종전 대비 전도성이 개선되도록 함은 물론 고온에서의 열선 자체가 과승(카본폴리머의 팽창)하더라도 상기 열선들의 안정적인 발열을 유도함으로써, 종전에 PTC열선에서 발생되던 스파크 발생 또는 화재의 위험을 미연에 방지할 수 있도록 하는 효과가 있다.As described above, the present invention provides a high density of carbon deposited or mixed on the inside and outside of the carbon polymer even when the core wire (first heating wire) and the outer wire (second heating wire) are heated to a high temperature. It is formed to lead to the bridge or in direct contact with the first and second heating wires to improve the conductivity compared to the past, as well as to induce stable heat generation of the heating wires even when the heating wire itself is heated at a high temperature (expansion of the carbon polymer). It is effective to prevent the risk of spark or fire that occurred in PTC heating wire.
다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.The following describes the present invention in more detail with reference to the accompanying drawings.

이에, 본 발명은 도 1에 도시된 바와 같이, 심선(N1:제1열선)의 외주면에 카본분말이 증착된 후 이를 감싸 씌우도록 형성되는 카본폴리머와, 그 외주면에 권선된 제2열선과, 그 외주면에 다시 증착되는 카본분말과, 그 외주면에 사출 결합되는 PVC피복이 결합되어 이루어지도록 형성된다.Accordingly, the present invention, as shown in Figure 1, the carbon polymer is formed on the outer circumferential surface of the core wire (N1: first heating wire) is formed so as to surround it, the second heating wire wound on the outer peripheral surface, The carbon powder deposited on the outer circumferential surface and the PVC coating injection-bonded to the outer circumferential surface are formed to be combined.
이에, 본 발명은 도 2에 도시된 바와 같이, 심선(제1열선)과 바깥선(제2열선)의 전도성을 크게 개선하도록 카본분말을 심선에 직접 닿도록 증착하는 한편, 바깥선에도 카본이 직접 닿아 전도성이 개선되도록 카본폴리머의 외주면에 카본분말을 도포하여 제작되도록 형성된다.Thus, the present invention, as shown in Figure 2, while depositing the carbon powder to directly contact the core wire to greatly improve the conductivity of the core wire (first heating wire) and the outer wire (second heating wire), while carbon is also in the outer wire It is formed to apply the carbon powder to the outer peripheral surface of the carbon polymer so as to improve the direct contact.
이때, 본 발명의 제조 방법은 도 3 내지 도 5에 도시된 바와 같이, 크게 1차 공급공정(S100), 제1카본 분말공급 공정(S200), 카본폴리머 공급공정(S300), 제2카본 분말공급 공정(S400), 제1냉각 후 롤링공정(S500), 2차 공급공정(S600), 제3카본 분말공급 공정(S700), PVC수지 공급공정(S800), 제2냉각 후 롤링공정(S900)이 구성되어 이루어진다.At this time, the manufacturing method of the present invention as shown in Figures 3 to 5, largely the first supply process (S100), the first carbon powder supply process (S200), the carbon polymer supply process (S300), the second carbon powder Supply process (S400), first cooling after rolling process (S500), secondary supply process (S600), third carbon powder supply process (S700), PVC resin supply process (S800), second cooling after rolling process (S900) ) Is made up of.
이에, 상기 1차 공급공정(S100)은 단심 또는 연심으로 된 심선(제1열선)을 센터가이드용 다이스를 통해 공급하도록 형성된다.Thus, the primary supply process (S100) is formed so as to supply a core wire (first heating wire) of a single core or core core through the die for the center guide.
즉, 상기 1차 공급공정은 심선이 직선방향으로 배출됨에 있어서, 후술되는 카본과 카본폴리머가 정밀하게 증착 또는 도포 또는 코팅되도록 기준점을 제공하도록 형성된다.That is, the primary supply process is formed to provide a reference point so that the carbon and the carbon polymer described later are precisely deposited or coated or coated in the core wire is discharged in a linear direction.
이때, 상기 제1카본 분말공급 공정(S200)은 상기 공급된 심선의 외주면에 카본분말을 증착시키도록 형성된다.At this time, the first carbon powder supply process (S200) is formed to deposit carbon powder on the outer peripheral surface of the supplied core wire.
즉, 상기 카본분말은 심선의 외주면에 직접적으로 증착되어 후술되는 카본폴리머의 카본과 바깥선(제2열선)이 브리지에 의해 원활히 연결되어 전도성이 크게 개선되도록 하기 위함이다.That is, the carbon powder is directly deposited on the outer circumferential surface of the core wire so that the carbon and the outer wire (second heating wire) of the carbon polymer, which will be described later, are smoothly connected by the bridge to significantly improve conductivity.
또한, 상기 카본폴리머 공급공정(S300)은 상기 제1카본이 증착된 심선의 외 주면에 용융상태의 카본폴리머를 씌어 사출시키도록 형성된다.In addition, the carbon polymer supplying step (S300) is formed so as to inject the carbon polymer in the molten state on the outer peripheral surface of the core wire on which the first carbon is deposited.
이때, 상기 카본폴리머의 카본분말은 전기저항이 높은 것을 사용하여 카본폴리머가 발열에 의해 팽창함으로써 카본과 카본간 전도성이 저하되어 전류공급을 격감시켜 PTC기능을 수행한다.In this case, the carbon powder of the carbon polymer uses a high electrical resistance, thereby expanding the carbon polymer by heat generation, thereby lowering conductivity between carbon and carbon, thereby reducing the current supply to perform a PTC function.
또한, 상기 제2카본 분말공급 공정(S400)은 상기 카본폴리머가 완전 경화되기 전에 점도가 있는 상태에서 외주면에 카본분말을 부착시키도록 형성된다.In addition, the second carbon powder supply process (S400) is formed to attach the carbon powder to the outer circumferential surface in the state of viscosity before the carbon polymer is completely cured.
즉, 카본폴리머가 용융된 상태에서 제2카본 분말을 증착시켜 마치 박히듯 결합된 후 건조되도록 형성된다.That is, the second carbon powder is deposited by melting the carbon polymer in a molten state, and is formed to be bonded after being dried together.
이는 후술되는 바깥선(제2열선)이 카본폴리머의 외주면으로 권선되면 전도층(제2열선과 카본폴리머의 사이)의 밀도가 고밀도로 이루어져 통전시 열선과 카본폴리머 사이에서 스파크와 같은 전기적 안전사고가 방지되도록 함은 물론 전도성을 개선하기 위함이다.This is because when the outer wire (second heating wire) described below is wound to the outer circumferential surface of the carbon polymer, the density of the conductive layer (between the second heating wire and the carbon polymer) becomes high density, so that an electrical safety accident such as a spark is generated between the heating wire and the carbon polymer when energizing. Is to prevent the well as to improve the conductivity.
이에, 상기 제1냉각 후 롤링공정(S500)은 상기 제2카본 분말공급이 완료된 상태에서 이를 급랭시키도록 냉각수조를 거치게한 후 모터에 의해 와인딩시켜 기본열선의 제작을 마무리하도록 형성된다.Thus, the first cooling after rolling process (S500) is formed to finish the production of the basic heating wire by winding by a motor after passing through the cooling water tank to quench it in a state in which the second carbon powder supply is completed.
즉, 상기 냉각수조는 용융상태의 카본폴리머에 카본분말이 박힌(점착) 상태를 바로 건조시켜 기본 열선을 신속하게 형성하도록 하기 위함이다.That is, the cooling water tank is to dry the carbon powder in the molten carbon polymer immediately (adhesion) immediately to form a basic heating wire.
이후 기본 열선은 별도의 보빈 또는 모터에 의해 당겨져 롤링되도록 한 뒤 후발 공정인 최종열선 제작 공정으로 이송되도록 형성된다.Thereafter, the basic heating wire is pulled by a separate bobbin or a motor to be rolled, and then formed to be transferred to a final heating wire manufacturing process that is a late stage process.
이때, 상기 2차 공급공정(S600)은 도 4에 도시된 바와 같이, 상기 기본열선 의 외주면에 바깥선(제2열선)을 권선한 후 이를 센터가이드용 다이스를 통해 공급하도록 형성된다.In this case, as shown in FIG. 4, the secondary supply process (S600) is formed to wind an outer wire (second heating wire) on an outer circumferential surface of the basic heating wire and then supply it through a die for a center guide.
즉, 기본열선의 외주면에 추가 카본분말과 피복을 씌움에 있어서 정밀한 배출이 이루어지도록 형성된다.That is, it is formed so that the precise discharge in the coating the additional carbon powder and the coating on the outer peripheral surface of the basic heating wire.
이에, 상기 제3카본 분말공급 공정(S700)은 상기 공급된 제2열선의 외주면에 카본분말을 증착시키도록 형성된다.Thus, the third carbon powder supply process (S700) is formed to deposit the carbon powder on the outer peripheral surface of the supplied second heating wire.
즉, 상기 카본분말은 제2열선 및 카본폴리머의 외주면과 직접적으로 증착되도록 형성되어 충분한 전류공급 선로를 이루도록 형성된다.That is, the carbon powder is formed to be deposited directly with the outer circumferential surface of the second heating wire and the carbon polymer to form a sufficient current supply line.
이때, 상기 PVC수지 공급공정(S800)은 상기 제3카본이 증착된 제2열선의 외주면에 용융상태의 피브씨(PVC)를 씌어 사출시키도록 형성된다.At this time, the PVC resin supply process (S800) is formed to be injected by covering the molten fibrous (PVC) on the outer peripheral surface of the second heating wire on which the third carbon is deposited.
이에, 상기 PVC수지는 절연 피복재료로서, 방습성, 절연성이 우수한 제품을 사용하는 것이 바람직하다.Accordingly, it is preferable to use a product having excellent moisture resistance and insulation property as the insulation coating material.
이에, 상기 제2냉각 후 롤링공정(S900)은 상기 사출된 피브씨(PVC)의 성형 후 발생된 과열을 냉각시키도록 냉각수조를 거치게 한 후 모터에 의해 와인딩시켜 최종열선의 제작을 마무리하도록 형성된다.Thus, the second cooling after rolling process (S900) is formed to finish the production of the final heating wire by winding by a motor after passing through a cooling water tank to cool the overheat generated after the molding of the injected fibrous (PVC) do.
즉, 최종적으로 사출에 의해 가열된 열선을 신속하게 냉각시켜 최종 제품을 완성하도록 형성된다.That is, it is formed to rapidly cool the hot wire finally heated by injection to complete the final product.
이때, 상기 카본폴리머 공급공정(S300)의 카본분말은 전기저항이 높은 것을 사용하여 카본폴리머가 발열에 의해 팽창함으로써 카본과 카본간 전도성이 저하되어 전류공급을 격감시켜 PTC기능을 수행하고, 상기 제1카본 분말공급 공정(S200), 제2카본 분말공급 공정(S400) 및 제3카본 분말공급 공정(S700)의 카본분말은 전기저항이 낮은 것을 사용하여 전도성이 원활하도록 형성되는 것이 바람직하다.At this time, the carbon powder of the carbon polymer supplying step (S300) uses a high electrical resistance, and the carbon polymer expands due to heat generation, thereby lowering the conductivity between carbon and carbon, thereby reducing the current supply to perform a PTC function, and Carbon powder of the first carbon powder supply process (S200), the second carbon powder supply process (S400), and the third carbon powder supply process (S700) is preferably formed to have good conductivity by using a low electrical resistance.
또한, 상기 제1카본 분말공급 공정(S200)과, 제2카본 분말공급 공정(S400)은 카본분말 대신 전도성이 우수한 동 분말, 황동 분말, 알루미늄 분말을 포함한 비철금속 분말 중 어느 하나를 사용하여 제1,2열선과 카본폴리머 간의 접촉저항을 최소화하도록 하는 것이 바람직하다.In addition, the first carbon powder supply process (S200) and the second carbon powder supply process (S400), the first carbon powder using any one of non-ferrous metal powder, including copper powder, brass powder, aluminum powder with excellent conductivity, instead of It is desirable to minimize the contact resistance between the heating element and the carbon polymer.
