최근에 화석연료의 고갈 염려 등으로 인해 전기로 구동되는 다양한 전기 구동 장치, 예컨대 전기자동차(Electric Vehicle), 하이브리드 전기자동차(Hybrid Electric Vehicle; HEV), 플러그-인 하이브리드 전기자동차(Plug-in HEV; PHEV) 등이 개발되고 있다. 전기자동차는 엔진 없이 배터리를 통한 전기에너지를 주 동력원으로 하는 자동차로서, 배출가스가 전혀 발생하지 않는다. 하이브리드 전기자동차는 엔진과 전기모터를 함께 사용하며, 엔진의 부하를 감소시켜 에너지 효율을 높일 수 있는 자동차이다. 그리고 플러그-인 하이브리드 전기자동차는 엔진과 전기모터를 함께 사용한다는 점에서 하이브리드 전기자동차에 해당되며, 배터리는 플러그-인을 통해 외부 전원으로 충전한다는 점에서 하이브리드 전기자동차와 차이가 있다.Recently, due to concerns about depletion of fossil fuels, various electric driving devices driven by electricity, for example, an electric vehicle, a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (Plug-in HEV); PHEVs) are being developed. An electric vehicle is a vehicle that uses electric energy through a battery as its main power source without an engine, and does not generate any exhaust gas. A hybrid electric vehicle uses an engine and an electric motor together, and can increase energy efficiency by reducing the load on the engine. A plug-in hybrid electric vehicle is a hybrid electric vehicle in that it uses both an engine and an electric motor, and it is different from a hybrid electric vehicle in that the battery is charged with an external power source through a plug-in.
이와 같은 전기 구동 장치 시장의 성장에도 불구하고 기술적으로 해결해야 될 난제 중 하나가 저온환경에서의 난방 효율의 극대화이다. 그 이유는 전기 구동 장치에 전기를 공급하기 위하여 배터리를 사용하게 되는데, 에너지 소모가 많은 열선 필름 히터를 사용할 경우, 주행거리의 감소를 유발하기 때문이다.Despite the growth of the electric drive device market, one of the technical challenges to be solved is maximizing heating efficiency in a low-temperature environment. The reason is that a battery is used to supply electricity to the electric driving device, and when a hot wire film heater that consumes a lot of energy is used, the mileage is reduced.
또한 열선 필름 히터는 부직포 등의 섬유 기판에 편물(Knitting)을 통하여 고정하게 되는데 생산 비용이 높고, 단선으로 인해 불량이 다량 발생되는 문제점이 있었다.In addition, the hot wire film heater is fixed to a fiber substrate such as a nonwoven fabric through knitting, but there is a problem in that the production cost is high and a large amount of defects are generated due to disconnection.
이러한 섬유 기판을 이용한 열선 필름 히터의 문제점을 극복하기 위하여 다양한 면상 발열 기술이 개발되고 있다.In order to overcome the problems of the hot wire film heater using such a fiber substrate, various planar heating technologies are being developed.

이러한 본 발명에 따른 면상발열체 히터의 발열부용 조성물은 폴리에스테르 레진(Polyester Resin); 은; 숙신산 다이메틸(숙신산, 다이메틸 에스테르(Butanedioic Acid, Dimethyl Ester) CAS 106-65-0); 메틸 글루타르산(글루타르산, 다이메틸 에스테르(Pentanedioic Acid, Dimethyl Ester) CAS 1119-40-0); 다이메틸 지방질(다이메틸 에스테르 아디프산(Cimethyl Ester Adipic Acid) CAS 627-93-0); 흑연; 및 말레인 산, 클로로에틸렌과 아세트산 비닐과의 중합체((Z)-2-부텐디 산, 중합체, 함유 클로로에텐 AND 에텐일 CAS 9005-09-8);을 사용하도록 한다.The composition for the heating part of the planar heating element heater according to the present invention is polyester resin; silver; Dimethyl Succinate (Butanedioic Acid, Dimethyl Ester CAS 106-65-0); methyl glutaric acid (Pentanedioic Acid, Dimethyl Ester CAS 1119-40-0); Dimethyl lipids (Dimethyl Ester Adipic Acid CAS 627-93-0); black smoke; and maleic acid, a polymer of chloroethylene and vinyl acetate ((Z)-2-butenediic acid, polymer, containing chloroethene AND ethenyl CAS 9005-09-8);
구체적으로는, 무게비 기준으로 폴리에스테르 레진 4~6 중량%; 은 53.5~54.5 중량%; 숙신산 다이메틸 6~8 중량%; 메틸 글루타르산 18~23 중량%; 다이메틸 지방질 6~8 중량%; 흑연 0.5~1.5 중량%; 및 말레인 산, 클로로에틸렌과 아세트산 비닐과의 중합체 4~7 중량%;의 함량을 이용한다.Specifically, 4 to 6% by weight of the polyester resin based on the weight ratio; 53.5-54.5 wt% silver; 6-8 wt% of dimethyl succinate; 18-23% by weight of methyl glutaric acid; 6-8% by weight of dimethyl lipid; 0.5-1.5 wt% graphite; and 4 to 7 wt% of a polymer of maleic acid, chloroethylene and vinyl acetate;
보다 구체적으로는, 폴리에스테르 레진 5 중량%; 은 54 중량%; 숙신산 다이메틸 7 중량%; 메틸 글루타르산 20 중량%; 다이메틸 지방질 7 중량%; 흑연 1 중량%; 및 말레인 산, 클로로에틸렌과 아세트산 비닐과의 중합체 6 중량%;의 함량을 이용한다.More specifically, 5% by weight of polyester resin; 54 wt % silver; 7% by weight of dimethyl succinate; 20% by weight of methyl glutaric acid; 7% by weight of dimethyl lipid; graphite 1% by weight; and 6% by weight of maleic acid, a polymer of chloroethylene and vinyl acetate;
이때, 은(Ag)은 면상발열체 히터의 열 도전성을 향상시키기 위하여 사용되며, 흑연은 면상발열체 히터의 열 보온성을 향상시키기 위하여 사용된다.At this time, silver (Ag) is used to improve the thermal conductivity of the planar heating element heater, and graphite is used to improve the thermal insulation of the planar heating element heater.
또한, 상기 흑연은 분말형태로 사용하도록 하되, 그 입자는 작을수록 좋다.In addition, the graphite is used in powder form, but the smaller the particles, the better.
또한, 은은 액상으로 가공된 것을 사용하도록 한다.In addition, silver processed in a liquid phase should be used.
즉, 최종적으로, 상술된 조성물들이 혼합되어 획득된 혼합물을 이용하여 면상발열체 히터의 표면에 도포되어, 최종적으로 면상발열체에 사용되는 히터를 제조하는 것이다.That is, finally, using the mixture obtained by mixing the above-described compositions is applied to the surface of the planar heating element heater, finally to manufacture a heater used for the planar heating element.
다만, 흑연은 본질의 특성상 이종의 조성물과 잘 혼합되지 않는다. 따라서, 본 발명에서는 고비점 용제로 페인트, 잉크, 세정제, 농약, 접착제, 가소제 등에 다양한 용도로 사용되는 다이메틸 지방질(DMA(dimethyl adipate CAS 627-93-0))을 이용하여 흑연이 타 조성물들과 원할하게 혼합될 수 있도록 한다.However, graphite does not mix well with heterogeneous compositions due to the nature of the material. Therefore, in the present invention, graphite and other compositions are prepared by using dimethyl lipid (DMA (dimethyl adipate CAS 627-93-0)) used for various purposes in paints, inks, detergents, pesticides, adhesives, plasticizers, etc. as a high boiling point solvent. and to mix smoothly.
여기서, 흑연은 열 보온성의 성질에 직접 연관되므로, 본 발명에서는 흑연의 혼합률을 시험하기 위하여 제조된 면상발열체 히터의 열 보온성을 평가하는 실험을 수행하였다.Here, since graphite is directly related to the property of thermal insulation, in the present invention, an experiment was performed to evaluate the thermal insulation of the planar heating element heater manufactured in order to test the mixing rate of graphite.
각 실험군은 흑연을 제외한 나머지 조성물의 함량을 조정하는 것으로 하였다. 사용된 실험군은 [표 1]과 같다.Each experimental group was to adjust the content of the remaining composition except for graphite. The experimental group used is shown in [Table 1].
※ 은(Ag)의 경우, 도전성에 관계되므로 보온성과는 거리가 있을 것으로 판단하였다. 또한, 배수 단위는 감소의 경우 2배수까지, 증가는 5배수까지 하여 함량 조절을 수행하였다. 따라서, 실험군 별로 총 7개의 히터를 제조하여 실험에 사용한 것이다.※ In the case of silver (Ag), it was judged that there would be a distance from heat retention because it was related to conductivity. In addition, content control was performed by multiplying units by up to 2 folds in the case of decrease and up to 5 folds in the case of increase. Therefore, a total of 7 heaters were manufactured for each experimental group and used in the experiment.
실험은, 위 실험군들을 통해 제조된 각각의 면상발열체를, 20 mm x 20 mm 사이즈의 쿼츠기판위에 ITO 나노입자 페이스트를 스핀코팅하여 박막을 형성한 후에, 300 ℃에서 30분, 700 ℃에서 1시간 열처리 공정을 진공상태에서 수행하였다. PDMS 레진(sylgard 184A)과 가교제(sylgard 184B)를 10:1 질량비로 혼합한 후, ITO 나노입자 박막 면상발열체 위에 코팅하고, 65 ℃에서 2시간 열처리를 수행하였다.The experiment was performed by spin-coating each planar heating element manufactured through the above experimental groups on a quartz substrate of 20 mm x 20 mm size to form a thin film, then at 300 ° C for 30 minutes, at 700 ° C for 1 hour. The heat treatment process was performed in a vacuum state. After mixing the PDMS resin (sylgard 184A) and the crosslinking agent (sylgard 184B) in a mass ratio of 10:1, the ITO nanoparticle thin film was coated on a planar heating element, and heat treatment was performed at 65 °C for 2 hours.
면상발열체의 온도는 적외선카메라 (FLIR-A645SC)의 열영상 이미지로부터 측정되었으며, 모든 실험은 대기 중상온에서 진행되었다.The temperature of the planar heating element was measured from the thermal image of an infrared camera (FLIR-A645SC), and all experiments were conducted at room temperature.
면상발열체에 전압을 인가하여 목표온도 60 ℃에 도달시킨 후 전원공급을 중단하여, 면상발열체의 온도를 측정하는 것으로 면상발열체의 온도유지 특성을 알아보았다.After reaching the target temperature of 60 ℃ by applying a voltage to the planar heating element, the power supply was stopped, and the temperature maintenance characteristics of the planar heating element were investigated by measuring the temperature of the planar heating element.
그리고 결과는, 각 실험군의 7개의 히터에 대하여 온도 상승까지의 시간과 온도가 상온으로 감소하기 까지의 시간들을 평균데이터로 산출하였다. 예컨대, 목적한 온도 60℃까지 상승되는데 걸린시간이 7개의 히터에 대하여 각각, 90, 90, 90, 90, 100, 100, 100초라면, 94.2초로 평균을 산출하는 것이다.As a result, the time until the temperature rise and the time until the temperature decreases to room temperature for the 7 heaters in each experimental group were calculated as average data. For example, if the time taken to rise to a target temperature of 60° C. is 90, 90, 90, 90, 100, 100, and 100 seconds for 7 heaters, respectively, the average is calculated as 94.2 seconds.
그 결과, [표 2]와 같이 나타났다.As a result, it was shown in [Table 2].
[표 2]에 따르면, 흑연 대비 다이메틸 지방질의 함량을 배수 단위로 증감소 조정된 실험군 4의 경우, 상온으로 온도가 저하되기까지 가장 오래 걸렸다. 즉, 보온성이 가장 우수한 것이다.According to [Table 2], in the case of Experimental Group 4, in which the content of dimethyl lipid was adjusted to increase or decrease in multiple units compared to graphite, it took the longest until the temperature was lowered to room temperature. That is, it is the most excellent in heat retention.
한편, 실험군 4의 경우 목적 온도 상승까지의 시간도 가장 짧게 나타났다. 이는 보온성이 향상됨에 따라 온도의 상승이 가속된 것으로 판단된다.On the other hand, in the case of experimental group 4, the time until the target temperature rise was also the shortest. It is judged that the increase in temperature is accelerated as the thermal insulation is improved.
결과적으로, 흑연의 혼합을 원할하게 하는 조성물은 다이메틸 지방질의 영향이 가장 큰 것으로 확인되었다.As a result, it was confirmed that the composition for smooth mixing of graphite had the greatest effect of dimethyl lipid.
이후, 본 출원인은 다이메틸 지방질의 함량의 흑연 대비 가장 적합한 함량을 찾기 위한 실험을 수행하였다.Thereafter, the present applicant conducted an experiment to find the most suitable content of dimethyl lipid compared to graphite.
실험은 위와 같이 동일하게 수행하되, 실험군은 [표 3]과 같이 설정하였다.The experiment was performed in the same manner as above, but the experimental group was set up as shown in [Table 3].

실험결과는 [표 4]를 참조한다.Refer to [Table 4] for the experimental results.
[표 4]에 따른 실험결과, 가장 우수한 결과값을 보인 것은, 폴리에스테르 레진 5 중량%; 은 54 중량%; 숙신산 다이메틸 7 중량%; 메틸 글루타르산 20 중량%; 다이메틸 지방질 7 중량%; 흑연 1 중량%; 및 말레인 산, 클로로에틸렌과 아세트산 비닐과의 중합체 6 중량%;의 함량을 이용한 실험군 4이다.Experimental results according to [Table 4], showing the best results, polyester resin 5% by weight; 54 wt % silver; 7% by weight of dimethyl succinate; 20% by weight of methyl glutaric acid; 7% by weight of dimethyl lipid; graphite 1% by weight; and 6 wt% of maleic acid, a polymer of chloroethylene and vinyl acetate; Experimental group 4 using the content.
다만, 실험군 3 및 실험군 5의 경우에도, 실험군 4보다 낮은 결과를 나타냈지만, 유의한 수준으로 확인되었다.However, in the case of Experimental Group 3 and Experimental Group 5, the results were lower than those of Experimental Group 4, but were confirmed to be significant.
반면, 실험군 5, 특히 실험군 6의 경우, 실험군 4에 비하여 흑연 대비 함량을 높였음에도 결과값이 낮아지는 양상을 나타냈는데, 이는 은의 함량이 줄어듬에 영향이 있는 것으로 판단되고, 특히 실험군 6에서부터의 은의 함량인 52 중량%부터는 히터의 성능 저하에 크게 영향을 주는 것으로 확인되었다.On the other hand, in the case of Experimental Group 5, especially Experimental Group 6, the result showed a decrease even though the content of graphite was increased compared to that of Experimental Group 4. From the content of 52 wt%, it was confirmed that the performance of the heater was greatly affected.
