Therefore, product defects can be reduced.
Description
본 발명은 인솔 및 인솔 제조방법에 대한 것으로서, 더욱 상세하게는 인솔에 사용되는 팽창흑연시트가 파손되더라도 열전도를 유지할 수 있는 열전도시트를 구비한 인솔 및 인솔 제조방법에 대한 것이다. The present invention relates to an insole and a method of manufacturing an insole, and more specifically, to an insole and a method of manufacturing an insole provided with a heat-conducting sheet that can maintain heat conduction even if the expanded graphite sheet used in the insole is damaged.
일반적으로 팽창흑연시트는 천연 흑연, 열분해 흑연, 카쉬 흑연 등의 흑연을 황산, 질산 등의 혼합 용액으로 처리하고, 세척하여 건조시킨 후 가열장치를 사용하여 고온에서 팽창화하고 이것을 롤 등으로 압연에 의해 시트화한 것을 말한다. In general, expanded graphite sheets are made by treating graphite such as natural graphite, pyrolytic graphite, and Cash graphite with a mixed solution of sulfuric acid and nitric acid, washing and drying, expanding at high temperature using a heating device, and rolling it with a roll, etc. This means that it has been converted into a sheet.
팽창흑연시트는 두께방향에 비해서 면방향의 열전도율이 커 열원으로부터의 열을 다른 장소로 이동시키기 위한 부재로서 사용되고 있다. 예를 들어 신발 깔창에 적용하여 사용할 경우, 팽창흑연시트를 적절한 크기로 절단한 후 상부 및 하부에 천, EVA 스폰지, 충격흡수재 등의 마감재를 접착하여 발열시트로 사용할 수 있다. Expanded graphite sheets have a higher thermal conductivity in the surface direction compared to the thickness direction, and are used as a member to transfer heat from a heat source to another location. For example, when applied to shoe insoles, the expanded graphite sheet can be cut to an appropriate size and then used as a heating sheet by attaching finishing materials such as cloth, EVA sponge, and shock absorbers to the upper and lower parts.
그러나, 상기의 팽창흑연시트를 이용한 발열시트의 경우, 부서지기 쉬운 팽창흑연의 특성으로 인하여 보행자의 체중 이나 보행시 지속적으로 가해지는 충격과 같은 외력에 의해 팽창흑연시트의 변형 또는 파손이 발생하였다. 이로 인하여 팽창흑연시트의 열전도가 저하될 뿐만 아니라 팽창흑연시트의 접착면이 떨어져 상부마감재와 하부마감재가 분리되고, 분리된 부위로 팽창흑연시트가 빠져나오는 등 제품의 기능을 상실하게 되는 문제가 있었다. However, in the case of the heating sheet using the above expanded graphite sheet, the expanded graphite sheet was deformed or damaged due to external forces such as the weight of the pedestrian or impacts continuously applied while walking due to the brittle nature of the expanded graphite. As a result, not only did the heat conduction of the expanded graphite sheet deteriorate, but the adhesive surface of the expanded graphite sheet fell, causing the upper and lower finishing materials to separate, and the expanded graphite sheet to come out through the separated area, resulting in loss of product functionality. .
본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 인솔에 사용되는 팽창흑연시트가 파손되더라도 열전도를 유지할 수 있는 열전도시트를 구비한 인솔 및 인솔 제조방법을 제공하는 것을 목적으로 한다. The present invention is intended to solve the above problems. The purpose of the present invention is to provide an insole with a heat conductive sheet that can maintain heat conduction even if the expanded graphite sheet used in the insole is damaged and a method of manufacturing the insole.
본 발명에 따른 인솔은 열전도시트수단과, 상부마감부와, 하부마감부를 포함한다. 상기 열전도시트수단은 흑연을 열처리하여 팽창시켜 시트화된 팽창흑연시트부와, 상기 팽창흑연시트부의 열전도를 확산시킬 수 있게 상기 팽창흑연시트부의 상면과 하면에 결합된 동판부를 구비하며, 일정간격 이격되어 상면에서 하면으로 관통된 복수의 관통공이 형성된다. 상기 상부마감부는 상기 열전도시트수단의 상부에 결합된다. 상기 하부마감부는 상기 열전도시트수단의 하부를 감싸도록 사출 발포되어 상기 상부마감부와 결합된다. The insole according to the present invention includes a heat-conducting sheet means, an upper closure portion, and a lower closure portion. The heat conduction sheet means includes an expanded graphite sheet portion formed into a sheet by heat-treating and expanding graphite, and a copper plate portion coupled to the upper and lower surfaces of the expanded graphite sheet portion to spread heat conduction of the expanded graphite sheet portion, and spaced at a predetermined interval. A plurality of through holes are formed from the upper surface to the lower surface. The upper closure part is coupled to the upper part of the heat-conducting sheet means. The lower finishing part is injection-foamed to surround the lower part of the heat-conducting sheet means and is coupled to the upper finishing part.
또한, 상기의 인솔에 있어서, 상기 팽창흑연시트부의 두께는 400 내지 500 
본 발명에 따른 인솔 제조방법은 팽창흑연시트 준비단계와, 동판 준비단계와, 동판결합단계와, 열전도시트제조단계와, 상부마감부결합단계와, 성형단계와, 완성단계를 포함한다. 상기 팽창흑연시트 준비단계는 흑연을 열처리하여 팽창시켜 시트화된 팽창흑연시트부를 준비한다. 상기 동판 준비단계는 상기 팽창흑연시트부의 열전도를 확산시키기 위한 동판부를 준비한다. 상기 동판결합단계는 접착제를 사용하여 상기 팽창흑연시트부의 상면과 하면에 각각 상기 동판부를 결합시킨다. 상기 열전도시트제조단계는 상기 동판결합단계에서 상기 동판부가 결합된 상기 팽창흑연시트부에 일정 간격 이격되어 상면에서 하면으로 관통된 복수의 관통공을 형성하고 인솔 형상으로 커팅하여 열전도시트수단을 제조한다. 상기 상부마감부결합단계는 접착제를 사용하여 인솔 형상으로 제조된 상기 열전도시트수단의 상부에 상부마감부를 결합시킨다. 상기 성형단계는 상기 상부마감부와 결합되어 상기 열전도시트수단이 노출되지 않게 상기 열전도시트수단의 하부를 감싸도록 하부마감부를 발포시켜 인솔 형상으로 성형시킨다. 상기 완성단계는 상기 열전도시트수단의 상부에 결합된 상기 상부마감부를 인솔 형상으로 커팅하여 인솔을 완성한다. The insole manufacturing method according to the present invention includes an expanded graphite sheet preparation step, a copper plate preparation step, a copper plate bonding step, a heat conductive sheet manufacturing step, an upper finish bonding step, a forming step, and a completion step. In the expanded graphite sheet preparation step, graphite is heat treated and expanded to prepare an expanded graphite sheet portion formed into a sheet. In the copper plate preparation step, a copper plate portion is prepared to diffuse heat conduction of the expanded graphite sheet portion. In the copper plate joining step, the copper plate portion is bonded to the upper and lower surfaces of the expanded graphite sheet portion, respectively, using an adhesive. In the heat-conducting sheet manufacturing step, in the copper plate combining step, a plurality of through holes are formed at regular intervals from the expanded graphite sheet portion to which the copper plate portion is coupled and penetrate from the upper surface to the lower surface, and the heat-conducting sheet means is manufactured by cutting into an insole shape. . In the upper finishing part coupling step, an upper finishing part is coupled to the upper part of the heat-conducting sheet means manufactured in the shape of an insole using an adhesive. In the forming step, the lower finishing part is combined with the upper finishing part to foam and form the insole shape so as to surround the lower part of the heat-conducting sheet means without exposing the heat-conducting sheet means. In the completion step, the upper finishing part coupled to the upper part of the heat-conducting sheet means is cut into an insole shape to complete the insole.
본 발명에 의하면, 팽창흑연시트의 양면에 동박이 결합된다. 이 경우, 외력에 의해 팽창흑연시트가 파손되더라도 동박을 통하여 열이 전달될 수 있으므로 열전도시트의 열전도성을 유지시킬 수 있다. According to the present invention, copper foil is bonded to both sides of the expanded graphite sheet. In this case, even if the expanded graphite sheet is damaged by external force, heat can be transmitted through the copper foil, so the thermal conductivity of the heat-conducting sheet can be maintained.
또한, 본 발명에 의하면, 하부마감부는 열전도시트의 하부를 감싸도록 사출 발포되어 열전도시트의 관통공을 통해 상부마감부와 결합된다. 이 경우, 관통공에 삽입된 하부마감부가 상부마감부와 결합되므로 팽창흑연시트가 변형 또는 파손되더라도 열전도시트에서 상부마감부와 하부마감부가 분리되는 것을 방지할 수 있다. 그래서 제품의 불량을 줄일 수 있다. In addition, according to the present invention, the lower finishing part is injection-foamed to surround the lower part of the heat-conducting sheet and is coupled to the upper finishing part through the through hole of the heat-conducting sheet. In this case, since the lower finishing part inserted into the through hole is coupled to the upper finishing part, it is possible to prevent the upper finishing part and the lower finishing part from being separated from the heat-conducting sheet even if the expanded graphite sheet is deformed or damaged. Therefore, product defects can be reduced.

도 1 내지 도 4를 참조하여 본 발명에 따른 인솔 및 인솔 제조방법의 일 실시예를 설명한다. An example of an insole and an insole manufacturing method according to the present invention will be described with reference to FIGS. 1 to 4.
먼저, 본 발명에 따른 인솔은 열전도시트수단(10)과, 상부마감부(20)와, 하부마감부(30)를 포함한다. First, the insole according to the present invention includes a heat-conducting sheet means (10), an upper closure portion (20), and a lower closure portion (30).
열전도시트수단(10)은 팽창흑연시트부(11)와, 동박부(13)를 구비하며, 관통공(15)이 형성된다. The heat-conducting sheet means 10 includes an expanded graphite sheet portion 11 and a copper foil portion 13, and a through hole 15 is formed.
팽창흑연시트부(11)는 흑연을 열처리하여 팽창시킨 후 시트화한 것이다. 여기서 팽창흑연시트부(11)의 두께는 대략 400 내지 500 
동박부(13)는 팽창흑연시트부(11)를 보호하는 한편 팽창흑연시트부(11)가 파손되더라도 열전도성을 유지시키는 역할을 한다. 이를 위하여 동박부(13)는 접착제(G)에 의해 팽창흑연시트부(11)의 상면과 하면에 각각 결합된다. 그래서 동박부(13)는 열전도성이 높으므로 팽창흑연시트부(11)가 파손되더라도 동박부(13)를 통하여 열이 전달될 수 있으므로 열전도시트수단(10)의 열전도성을 유지할 수 있다. 여기서 동박부(13)의 각각의 두께는 6 내지 8 
관통공(15)은 열전도시트수단(10)의 상면에서 하면으로 관통되며, 일정 간격 이격되어 복수개 형성된다. The through-holes 15 penetrate from the upper surface to the lower surface of the heat-conducting sheet means 10, and are formed in plural numbers at regular intervals.
상부마감부(20)는 열전도시트수단(10)의 상부에 접착제(G)에 의해 결합된다. 여기서 상부마감부(20)는 천, 가죽, 섬유 등 사용자의 필요에 따라 다양한 재료가 사용될 수 있다.The upper finishing portion 20 is coupled to the upper part of the heat-conducting sheet means 10 with an adhesive G.
