Abstract

In the present invention, a graphene resin solution is prepared by mixing graphene and a highly viscous natural rubber synthetic acrylic resin, and the solution is coated on a fabric to produce a graphene fabric. The produced graphene fabric is attached to a heating wire of the electric mat, such that the temperature of the heating wire of the electric mat is increased near the heating wire, and the entire mat to which the graphene fabric is attached is warm. As a result, the amount of heat wires used in the electric mat is reduced, and electromagnetic waves harmful to a human body are also reduced due to the reduction in the amount of heat wires used. In addition, the lifespan of a thermostat increases and electricity bills decrease due to the reduced amount of heating wires.

Description

전기매트용 그래핀시트의 제조방법{Manufacturing method of graphene sheet for electric mat}Manufacturing method of graphene sheet for electric mat {Manufacturing method of graphene sheet for electric mat}

기존의 전기매트는 주로 외피와 내피 사이에 발열선을 일정간격으로 배열하고 이를 부직포로 덧대어 재봉하는 방식이 주를 이루었다. Existing electric mats mainly consisted of a method of arranging heating wires at regular intervals between an outer skin and an inner skin and sewing them by attaching them with non-woven fabric.

최근에는 기존의 전기매트에 쿠션기능을 넣거나 원적외선을 방사할 수 있는 광물질 등을 포함하는 시트층을 삽입하여 보다 고급스러운 기능성 전기매트가 많이 판매되고 있다. Recently, many more luxurious functional electric mats are being sold by inserting a cushion function into existing electric mats or by inserting a sheet layer containing a mineral capable of emitting far-infrared rays.

그러나 이러한 종래의 기능성 전기매트는 그 추가된 기능성으로 인해 파손의 위험이 높고 제품의 불량률 자체가 상승하게 된다.However, such a conventional functional electric mat has a high risk of damage due to its added functionality, and the defective rate of the product itself increases.

이를 해결하기 위한 기존의 기술로는 전기매트의 두께를 높여 구겨짐을 방지하고 쿠션감을 주는 방식으로 발전하여 왔다. Existing technologies for solving this problem have been developed by increasing the thickness of the electric mat to prevent wrinkles and to provide a cushioning feeling.

종래의 방식인 전기매트의 두께를 높이기 위하여 PVC매트를 상부에 부착하고 하부에 별도의 쿠션층을 두는 제조법은 pvc매트의 두께 등으로 인해 보다 높은 전력을 요구하였고 또 이를 해결하기 위해 하부 층에 단열효과를 가지는 단열층 가해야 하였다.The conventional manufacturing method of attaching a PVC mat to the upper part and placing a separate cushion layer on the lower part in order to increase the thickness of the electric mat required higher power due to the thickness of the pvc mat, and to solve this, insulation was applied to the lower layer. An insulating layer had to be applied to have an effect.

이런 방식으로 전기매트의 가격은 계속 높아져만 갔으며, 복잡한 매트의 구조로 인해 전기매트의 수명은 낮아지게 되었다.In this way, the price of electric mats continued to rise, and the lifespan of electric mats was reduced due to the complicated structure of the mat.

또한 전기매트의 구성상 발열선을 포함할 수밖에 없고, 복잡한 구조와 두꺼운 부자재의 사용 등으로 필요이상의 발열선이 들어가고 또 필요이상의 고열을 필요로 하게 되어 통상의 전기매트보다 많은 전자파가 발생함이 당연시 된다. 이로 인한 전자파의 문제는 항상 골칫거리로 남아있게 되었다.In addition, due to the configuration of the electric mat, it is inevitable to include a heating wire, and due to the complicated structure and the use of thick subsidiary materials, more heating wires than necessary and higher heat than necessary are required, so that more electromagnetic waves than normal electric mats are generated. It is taken for granted. Due to this, the problem of electromagnetic waves has always remained a headache.

이러한 문제점을 해결하기 위해 대한민국 등록특허 제10-1540439호는 그래핀 시트와 이를 구비한 발열 매트에 관한 것으로서, 내피 및 외부 사이에 쿠션재를 포함하고 발열선과 전자파 차단 부재 및 그래핀 시트를 포함함으로써 발열선에 의해 온열이 빠른 시간에 이루어짐과 동시에 사용자의 신체 깊숙한 지점까지 전달되도록 구성된 발열 매트를 제안하였다. 그러나 이 기술은 기존의 발열선을 사용하므로 전자파 발생의 문제가 있으며, 이를 개선하기 위해 전자파 차단 부재를 포함하고 있으나 이러한 부재를 사용하더라도 전자파가 완전 차단되는 것은 아니며 이러한 부재로 인해 제조 공정과 제조 원가가 상승하는 문제가 있다.In order to solve this problem, Korean Patent Registration No. 10-1540439 relates to a graphene sheet and a heating mat having the same, and includes a cushioning material between an inner skin and an exterior, and includes a heating wire, an electromagnetic wave blocking member, and a graphene sheet to provide a heating wire. proposed a heating mat configured to deliver heat to a point deep in the user's body at the same time as quickly as possible. However, since this technology uses the existing heating wire, there is a problem of electromagnetic wave generation, and to improve this, electromagnetic wave blocking members are included, but even if these members are used, electromagnetic waves are not completely blocked, and these members increase the manufacturing process and manufacturing cost. There is a rising problem.

또한, 대한민국 등록특허 제10-1528487호는 그래핀 면상 발열체에 관한 기술을 제안하였다. 이 기술에서는 그래핀을 인쇄한 인쇄층과 동 나노 코팅층이 형성된 면체 구조로서, 상기 그래핀이 인쇄된 인쇄층으로 인해 면상 발열체의 유연성이 증대되어 사용 수명이 연장되며, 동 나노 코팅층으로 인해 살균, 제독, 탈취 기능과 전자파 차단 기능, 수맥 차단 기능이 부여될 수 있음을 장점으로 설명한다. 그러나 이 기술에서는 발열체로서 전극을 포함함으로써 전자파가 필연적으로 발생되며, 이를 개선하기 위해 동 나노 코팅층을 추가로 포함해야 하므로 제조공정과 제조 원가가 상승하는 문제가 있다. In addition, Korean Patent Registration No. 10-1528487 proposed a technology related to a planar heating element of graphene. In this technology, it is a faceted structure in which a graphene printed layer and a copper nano-coating layer are formed. The graphene-printed printed layer increases the flexibility of the planar heating element and extends its useful life, and the copper nano-coating layer sterilizes, It is explained as an advantage that it can be given detoxification, deodorization function, electromagnetic wave blocking function, and water vein blocking function. However, in this technology, since electromagnetic waves are inevitably generated by including an electrode as a heating element, and a copper nano-coating layer must be additionally included to improve this, there is a problem in that the manufacturing process and manufacturing cost increase.

또한, 대한민국 등록특허 제10-1724542호는 그래핀을 이용한 쿨 매트 및 온열 겸용 쿠션 매트의 제조방법에 관한 기술을 제공한다. 이 기술에서는 직물지에 그래핀을 용액화하여 함침하는 방식으로 매트를 제조한다. 이는 그래핀의 열전도특성을 이용한 온열 및 쿨 기능성 제품으로 실생활에서 인체의 체온에 장시간 노출 시 그 기능성이 미미해지는 문제가 있다. In addition, Korean Patent Registration No. 10-1724542 provides a method for manufacturing a cool mat and a thermal cushion mat using graphene. In this technology, a mat is manufactured by solutionizing and impregnating graphene on textile paper. This is a thermal and cool functional product using the thermal conductivity of graphene, and there is a problem that its functionality becomes insignificant when exposed to the human body temperature for a long time in real life.

본 발명에서는 그리핀을 활용하여 동절기에는 40℃ 이상의 높은 온도로 발열할 수 있고, 높은 온도로 발열함으로 발열선의 길이가 상대적으로 줄어들어 전기매트의 원가절감을 할 수 있으며, 줄어든 발열선으로 인해 전자파 역시 줄어들며, 또한 줄어든 발열선으로 인해 전기요금 역시 낮아지는 효과를 가지며 줄어든 전력소모로 인해 전기매트의 수명 역시 올라가는 전기매트를 제조하는 기술을 제공하고자 한다.In the present invention, by using the griffin, heat can be generated at a high temperature of 40 ° C or more in winter, and the length of the heating wire can be relatively reduced by heating at a high temperature, thereby reducing the cost of the electric mat. Due to the reduced heating wire, electromagnetic waves are also reduced, In addition, it is intended to provide a technology for manufacturing an electric mat that has the effect of lowering electricity rates due to the reduced heating wire and also increases the lifespan of the electric mat due to reduced power consumption.

본 발명은 2020년 출원한 특허 ‘각종 시설물의 오염방지 도장용 도료 제조방법(출원번호 10-2020-0129205)’의 기본 수지에 천연고무와 아크릴수지를 첨가하여 접착성이 뛰어나고 경화 후 탄성이 높은 기본수지를 발명하게 되었고, 이를 기존 그래핀을 첨가하여 수지의 결합에 적용한 결과 그래핀기본수지가 만들어지게 되었다. The present invention has excellent adhesiveness and high elasticity after curing by adding natural rubber and acrylic resin to the basic resin of the patent 'Method for manufacturing paint for antifouling coating of various facilities (Application No. 10-2020-0129205)' filed in 2020. A basic resin was invented, and as a result of applying it to the bonding of resins by adding existing graphene, a graphene base resin was created.

만들어진 그래핀기본수지는 기본수지와 그래핀의 배합으로서 기본수지의 고탄성과 그래핀의 열전도율의 특성이 잘 들어나는 효과를 가지며 다양한 원단과의 함침시 그 기능성이 더욱 증대되는 효과를 가지는 수지로서 기능을 한다.The prepared graphene base resin is a combination of the base resin and graphene, and has the effect of revealing the high elasticity of the base resin and the thermal conductivity of graphene, and functions as a resin having the effect of further increasing its functionality when impregnated with various fabrics. do

이러한 결과를 가지고 기본수지와 그래핀을 첨가하여 배합한 그래핀기본수지는 원단에 합침하였을 때 원단의 특성인 구겨짐을 그대로 가지고 있고, 또한 원상회복이 쉽고, 잘 늘어나는 성질의 그래핀원단을 제조하게 되었다. Based on these results, the graphene base resin blended by adding the base resin and graphene retains the wrinkles, which are the characteristics of the fabric when impregnated with the fabric, and is easy to recover to its original state, making it possible to manufacture graphene fabric with good stretch properties. It became.

상기의 그래핀원단을 제조할 시 가장 중요한 점은 원단에 다양한 패턴을 기입하여 부분적 그래핀을 적용하는 것이다. The most important point in manufacturing the above graphene fabric is to partially apply graphene by writing various patterns on the fabric.

원단에 그래핀을 전체 코팅하는 것과 원단에 특수한 패턴을 입력하여 부분 코팅하는 것은 만들어진 그래핀원단의 단가형성에 막대한 차이를 발생시키며, 여러번의 실험결과 원단에 패턴을 적용시키면 동일한 면적 대비 최소 10%의 그래핀 코팅면적으로도 충분한 열전달 효과를 나타내었다. Full coating of graphene on the fabric and partial coating by entering a special pattern on the fabric cause a huge difference in the unit price of the graphene fabric made, and as a result of several experiments, applying the pattern to the fabric can reduce the cost by at least 10% compared to the same area. Even with the graphene coating area of , it showed sufficient heat transfer effect.

만들어진 상기의 그래핀 원단은 기본그래핀수지와 함침하는 원단의 특성에 따라 다양한 기능성을 가지는 그래핀원단으로 만들어졌다.The prepared graphene fabric was made of a graphene fabric having various functionalities according to the characteristics of the fabric to be impregnated with the basic graphene resin.

상기의 그래핀원단을 사용한 전기매트의 제작에는 다음과 같은 순서로서 제작을 한다.The manufacturing of the electric mat using the graphene fabric is performed in the following order.

그래핀 원단이 전기매트의 상층부에 위치하고 그 아래 부직포가 위치하며, 그 아래 발열선이 위치하며 그 아래 부직포가 위치하며, 그 아래 단열재가 위치하며, 그 아래 쿠션을 위한 직물층이 위치하며, 그 아래 제품보호를 위한 시트가 위치한다.The graphene fabric is located on the upper part of the electric mat, the non-woven fabric is located below it, the heating wire is located below it, the non-woven fabric is located below it, the insulation material is located below it, and the fabric layer for cushion is located below it. A sheet for product protection is located.

이렇게 만들어진 그래핀 원단 전기매트는 온열매트로 기능하기에 충분한 역할을 하지만 그래핀원단의 특성으로 인해 필요이상의 온열기능을 하였다.The graphene fabric electric mat made in this way plays a sufficient role to function as a thermal mat, but due to the characteristics of the graphene fabric, it has a more heating function than necessary.

하여 본 발명에서는 적절한 온열매트로서 기능하기 위해 통상의 전기매트보다 발열선의 길이를 줄이는 방법으로 전기매트를 제작하였다.Therefore, in the present invention, in order to function as an appropriate thermal mat, the electric mat was manufactured by reducing the length of the heating wire compared to conventional electric mats.

본 발명에서는 그래핀 배합수지와 다양한 원단을 합침하여 그래핀원단을 제조하였다. 그 결과 각각의 원단에서는 다음과 같은 장점이 있으며, 일반원단을 기능성 원단으로 제품에 적용이 가능하였다. In the present invention, a graphene fabric was prepared by incorporating a graphene blending resin and various fabrics. As a result, each fabric has the following advantages, and it was possible to apply general fabrics to products as functional fabrics.

상기의 결과를 토대로 본 발명에서는 폴리에스테르계열의 원단을 합침한 그래핀원단을 제조하였으며, 이를 사용하여 전기매트로 제작을 하였다. Based on the above results, in the present invention, a graphene fabric in which a polyester-based fabric is impregnated was prepared, and an electric mat was manufactured using the graphene fabric.

본 발명에서는 별도의 마감 층을 사용하지 않고 그래핀원단을 마감 층으로 사용하였다. In the present invention, a graphene fabric was used as a finishing layer without using a separate finishing layer.

기존의 전기매트 혹은 대한민국 등록특허 제10-1724542호 그래핀을 이용한 쿨 매트 및 온열 겸용 쿠션 매트의 제조방법에 관한 기술보다 높은 열 전도성을 가지게 되었고, 이는 곧 높은 열효율을 가진 제품을 제조하게 되었다. It has higher thermal conductivity than the existing electric mat or the technology for manufacturing a cool mat and a thermal cushion mat using graphene (Korean Patent Registration No. 10-1724542), which soon led to the manufacture of products with high thermal efficiency.

또한 본 발명에서는 그래핀 원단에 패턴을 기입하여 코팅하는 방식으로 원단에 사용된 그래핀수지의 양을 줄였으며, 이로 인해 상당한 원가절감을 기록하였다. In addition, in the present invention, the amount of graphene resin used in the fabric was reduced by writing a pattern on the graphene fabric and coating it, thereby recording a significant cost reduction.

또한 본 발명에서는 그래핀 원단의 사용으로 기존의 전기매트보다 더욱 효과적인 온열기능을 발휘할 수 있었고, 이로 인해 발열선의 부위에만 높은 온도가 발생하는 문제점도 해결이 되었다.In addition, in the present invention, by using the graphene fabric, a more effective heating function than conventional electric mats can be exhibited, and as a result, the problem of high temperature occurring only in the heating wire area has been solved.

본 발명에서는 이에 대한 해결책으로 발열선의 길이를 단계적으로 줄이면서 시험한 결과 그래핀원단의 적절한 사용과 발열선의 적절한 길이가 효과적으로 기능하는 구간을 발견하였다.In the present invention, as a solution to this, as a result of testing while reducing the length of the heating wire step by step, a section in which the proper use of the graphene fabric and the appropriate length of the heating wire effectively functioned was found.

위의 표는 통상적으로 사용하는 퀀사이즈 전기매트속에 들어가는 발열선과 본 발명으로 인해 만들어진 그래핀원단의 패턴을 수정하여 적용해본 결과 전기매트의 표면 발열온도를 측정해본 것이다. 실험을 보다 공정하게 하기위해 전기매트의 표면온도를 측정한 것이 아니라 전기매트 위에 가로세로 1m의 동판을 올려 그 동판의 표면온도를 측정한 것이다.The table above measures the surface heating temperature of the electric mat as a result of modifying and applying the pattern of the heating wire inserted into the conventionally used queen size electric mat and the graphene fabric made according to the present invention. In order to make the experiment fairer, the surface temperature of the electric mat was not measured, but the surface temperature of the copper plate was measured by placing a 1m x 1m copper plate on the electric mat.

겨울철 인체가 쾌적하게 수면할 수 있는 전기매트의 온도를 35℃라 하였을 때 발열선의 길이가 20m 일 경우 그래핀패턴 20%(면적대비)의 사용으로 35℃의 쾌적한 온도를 유지하였으며, 그래핀 패턴이 30%가 넘어갈수록 35℃의 온도를 유지하기 위한 발열선의 길이는 줄어들었다. When the temperature of an electric mat where the human body can sleep comfortably in winter is 35℃, when the length of the heating wire is 20m, a comfortable temperature of 35℃ is maintained by using 20% of the graphene pattern (relative to the area), and the graphene pattern As this 30% exceeded, the length of the heating wire to maintain the temperature of 35 ° C was reduced.

위의 실험결과로 본 발명에서는 발열선의 길이 25m와 그래핀패턴 30%를 사용한 그래핀원단을 적용하여 제품을 제작하였다. 이는 발열선의 경우 1m당 1,500원 정도의 단가가 소요되는 반면, 그래핀원단의 경우 원단의 면적대비 20% 12,000원, 30% 15,000원, 40% 20,000원, 50% 25,000원 등으로 소요되었기 때문에 가장 효과적인 구간인 발열선의 길이 20m와 그래핀원단의 패턴 30%의 사용이기 때문이다. As a result of the above experiment, in the present invention, a product was manufactured by applying a graphene fabric using a heating wire length of 25 m and a graphene pattern of 30%. This is the most expensive because the heating wire costs about 1,500 won per 1m, whereas the graphene fabric costs 20% 12,000 won, 30% 15,000 won, 40% 20,000 won, and 50% 25,000 won compared to the area of the fabric. This is because the length of the heating wire, which is an effective section, is 20m and the pattern of graphene fabric is 30%.

상기의 결과로서 그래핀원단의 사용 시 일반매트 대비 발열선의 길이는 16m(일반매트 기준 36m)가 줄어들었으며, 온도는 2℃가 올라가는 긍정적인 효과를 발견하였으며, 이는 상대적으로 35℃의 온도로 전기매트를 작동하는 전기의 전력량 역시 일반매트 대비 30% 이상 줄어드는 긍정적인 효과를 나타내었다. As a result of the above, when using the graphene fabric, the length of the heating wire was reduced by 16 m (36 m based on the general mat) compared to the general mat, and the positive effect of increasing the temperature by 2 ° C was found, which is relatively 35 ° C. The amount of electricity used to operate the mat was also reduced by more than 30% compared to general mats, showing a positive effect.

상기의 결과로서 나타나는 중요한 효과중 하나는 전기매트의 발열선이 줄어들어 전력의 사용량이 줄어들면 상대적으로 전기매트의 조절기 부분의 수명이 상당부분 늘어나는 효과역시 발견이 되었다.One of the important effects that appear as a result of the above is that the lifespan of the controller part of the electric mat is relatively increased when the amount of electricity used is reduced due to the reduction of the heating wire of the electric mat.

본 발명에서는 그래핀 배합수지와 다양한 원단을 합침하여 그래핀원단을 제조하였다. 그 결과 각각의 원단에서는 다음과 같은 장점이 있으며, 일반원단을 기능성 원단으로 제품에 적용이 가능하였다. In the present invention, a graphene fabric was prepared by incorporating a graphene blending resin and various fabrics. As a result, each fabric has the following advantages, and it was possible to apply general fabrics to products as functional fabrics.

상기의 결과를 토대로 본 발명에서는 폴리에스테르계열의 원단을 합침한 그래핀원단을 제조하였으며, 이를 사용하여 전기매트로 제작을 하였다. Based on the above results, in the present invention, a graphene fabric in which a polyester-based fabric is impregnated was prepared, and an electric mat was manufactured using the graphene fabric.

본 발명에서는 별도의 마감 층을 사용하지 않고 그래핀원단을 마감 층으로 사용하였다. In the present invention, a graphene fabric was used as a finishing layer without using a separate finishing layer.

기존의 전기매트 혹은 대한민국 등록특허 제10-1724542호 그래핀을 이용한 쿨 매트 및 온열 겸용 쿠션 매트의 제조방법에 관한 기술보다 높은 열 전도성을 가지게 되었고, 이는 곧 높은 열효율을 가진 제품을 제조하게 되었다. It has higher thermal conductivity than the existing electric mat or the technology for manufacturing a cool mat and a thermal cushion mat using graphene (Korean Patent Registration No. 10-1724542), which soon led to the manufacture of products with high thermal efficiency.

또한 본 발명에서는 그래핀 원단에 패턴을 기입하여 코팅하는 방식으로 원단에 사용된 그래핀수지의 양을 줄였으며, 이로 인해 상당한 원가절감을 기록하였다. In addition, in the present invention, the amount of graphene resin used in the fabric was reduced by writing a pattern on the graphene fabric and coating it, thereby recording a significant cost reduction.

또한 본 발명에서는 그래핀 원단의 사용으로 기존의 전기매트보다 더욱 효과적인 온열기능을 발휘할 수 있었고, 이로 인해 발열선의 부위에만 높은 온도가 발생하는 문제점도 해결이 되었다.In addition, in the present invention, by using the graphene fabric, a more effective heating function than conventional electric mats can be exhibited, and as a result, the problem of high temperature occurring only in the heating wire area has been solved.

본 발명에서는 이에 대한 해결책으로 발열선의 길이를 단계적으로 줄이면서 시험한 결과 그래핀원단의 적절한 사용과 발열선의 적절한 길이가 효과적으로 기능하는 구간을 발견하였다.In the present invention, as a solution to this, as a result of testing while reducing the length of the heating wire step by step, a section in which the proper use of the graphene fabric and the appropriate length of the heating wire effectively functioned was found.

위의 표는 통상적으로 사용하는 퀀사이즈 전기매트속에 들어가는 발열선과 본 발명으로 인해 만들어진 그래핀원단의 패턴을 수정하여 적용해본 결과 전기매트의 표면 발열온도를 측정해본 것이다. 실험을 보다 공정하게 하기위해 전기매트의 표면온도를 측정한 것이 아니라 전기매트 위에 가로세로 1m의 동판을 올려 그 동판의 표면온도를 측정한 것이다.The table above measures the surface heating temperature of the electric mat as a result of modifying and applying the pattern of the heating wire inserted into the conventionally used queen size electric mat and the graphene fabric made according to the present invention. In order to make the experiment fairer, the surface temperature of the electric mat was not measured, but the surface temperature of the copper plate was measured by placing a 1m x 1m copper plate on the electric mat.

겨울철 인체가 쾌적하게 수면할 수 있는 전기매트의 온도를 35℃라 하였을 때 발열선의 길이가 20m 일 경우 그래핀패턴 20%(면적대비)의 사용으로 35℃의 쾌적한 온도를 유지하였으며, 그래핀 패턴이 30%가 넘어갈수록 35℃의 온도를 유지하기 위한 발열선의 길이는 줄어들었다. When the temperature of an electric mat where the human body can sleep comfortably in winter is 35℃, when the length of the heating wire is 20m, a comfortable temperature of 35℃ is maintained by using 20% of the graphene pattern (compared to the area), and the graphene pattern As this 30% exceeded, the length of the heating wire to maintain the temperature of 35 ° C was reduced.

위의 실험결과로 본 발명에서는 발열선의 길이 25m와 그래핀패턴 30%를 사용한 그래핀원단을 적용하여 제품을 제작하였다. 이는 발열선의 경우 1m당 1,500원 정도의 단가가 소요되는 반면, 그래핀원단의 경우 원단의 면적대비 20% 12,000원, 30% 15,000원, 40% 20,000원, 50% 25,000원 등으로 소요되었기 때문에 가장 효과적인 구간인 발열선의 길이 20m와 그래핀원단의 패턴 30%의 사용이기 때문이다. As a result of the above experiment, in the present invention, a product was manufactured by applying a graphene fabric using a heating wire length of 25 m and a graphene pattern of 30%. This is the most expensive because the heating wire costs about 1,500 won per 1m, whereas the graphene fabric costs 20% 12,000 won, 30% 15,000 won, 40% 20,000 won, and 50% 25,000 won compared to the area of the fabric. This is because the length of the heating wire, which is an effective section, is 20m and the pattern of graphene fabric is 30%.

상기의 결과로서 그래핀원단의 사용 시 일반매트 대비 발열선의 길이는 16m(일반매트 기준 36m)가 줄어들었으며, 온도는 2℃가 올라가는 긍정적인 효과를 발견하였으며, 이는 상대적으로 35℃의 온도로 전기매트를 작동하는 전기의 전력량 역시 일반매트 대비 30% 이상 줄어드는 긍정적인 효과를 나타내었다. As a result of the above, when using the graphene fabric, the length of the heating wire was reduced by 16 m (36 m based on the general mat) compared to the general mat, and the positive effect of increasing the temperature by 2 ° C was found, which is relatively 35 ° C. The amount of electricity used to operate the mat was also reduced by more than 30% compared to general mats, showing a positive effect.

상기의 결과로서 나타나는 중요한 효과중 하나는 전기매트의 발열선이 줄어들어 전력의 사용량이 줄어들면 상대적으로 전기매트의 조절기 부분의 수명이 상당부분 늘어나는 효과역시 발견이 되었다.One of the important effects that appear as a result of the above is that the lifespan of the controller part of the electric mat is relatively increased when the amount of electricity used is reduced due to the reduction of the heating wire of the electric mat.
