Description
본 발명은 산업용 카본 및 그 제조방법에 관한 것으로, 구체적으로 전도성이 우수한 카본 및 그 제조 방법에 관한 것이다. 특히 카본은 기계구조이나 각종 회전기기에 사용되고, 산업용 카본 제품의 전도성은 운전능력을 좌우하는 핵심 요소이다. 그러나 국내 카본제품의 전도성은 요소 기술의 낙후로 선진사 대비 70~80% 수준이고, 이 같은 낙후된 국내 기술로 인하여 산업용 카본 제품은 전량 수입된다.현재 회전기기용 산업용 카본의 경우, 일반용 보다 높은 전기 전도성이 요구된다. 이 같은 전기 전도성은 구리를 단순 첨가하는 방법으로 부여한다. 그러나 구리 단순 첨가는 구리의 농도에 비례해서 내마모성이 저하되는 결과를 초래함으로서 내마모성이 저하되지 않고 전기 전도성을 증가시킬 수 있는 방법이 필요하다.The present invention relates to industrial carbon and a method for producing the same, and more particularly, to a carbon having excellent conductivity and a method for producing the same. In particular, carbon is used in mechanical structures and various rotating machines, and the conductivity of industrial carbon products is a key factor in determining driving ability. However, the conductivity of domestic carbon products is 70 ~ 80% of the advanced companies due to the fall of urea technology, and the industrial carbon products are imported in all due to this fall domestic technology. Conductivity is required. Such electrical conductivity is imparted by a simple addition of copper. However, since the simple addition of copper results in a decrease in wear resistance in proportion to the concentration of copper, a method capable of increasing electrical conductivity without reducing wear resistance is needed.
본 발명은 카본의 전도성을 증가시키기 위해 구리를 단순 첨가하는 기존의 방법과 달리 나노 크기의 산화 인듐을 카본 표면에 부착하여 전도성을 향상시킨다.나노 크기의 산화인듐 부착은 일반적인 혼합에 의한 전도성 물질의 첨가보다 더 적은 농도로 입자간 전도성 네트워크를 형성해 전도성 물질이 많아질 때의 문제점인 내마모성 문제를 해결할 수 있고, 더 높은 전도성을 부여할 수 있다. 이 같은 전도성 물질의 부착은 농도에 따른 카본 제품의 내마모성 저하를 방지함으로서 궁극적으로 카본 제품의 내마모성을 강화시킬 수 있다.The present invention improves the conductivity by attaching nano-sized indium oxide to the carbon surface, unlike the conventional method of simply adding copper to increase the conductivity of carbon. It can form the intergranular conductive network at a lower concentration than the addition, thereby solving the problem of wear resistance, which is a problem when the conductive material is increased, and can impart higher conductivity. Attachment of such a conductive material prevents the wear resistance of the carbon product from decreasing with concentration, thereby ultimately enhancing the wear resistance of the carbon product.
상기한 본 발명의 목적을 달성하기 위하여 본 발명은 카본표면에 산화 인듐을 부착하여 전기 전도성이 개선된 카본을 제공하는 것이다. 이하 본 발명을 더욱 상세히 설명한다.상기 카본 100g에 대하여 0.1내지 10 wt% 산화 인듐을 첨가하여 10분내지 30분 교반하는 것이 바람직하다. 산화 인듐과 순수의 무게 비는 1:5내지 1:10로 하여 2일 내지 10일 ball-mill하여 나노 크기의 산화 인듐을 만드는 것이 바람직하다.In order to achieve the above object of the present invention, the present invention is to provide a carbon with improved electrical conductivity by attaching indium oxide to the carbon surface. Hereinafter, the present invention will be described in more detail. It is preferable to add 0.1 to 10 wt% indium oxide to 100 g of the carbon and stir for 10 to 30 minutes. The weight ratio of indium oxide and pure water is 1: 5 to 1:10, and it is preferable to make a nano-sized indium oxide by ball-milling for 2 to 10 days.
상기 나노 크기의 산화 인듐을 카본에 부착하기 위하여 카본과 순수를 1:3의 무게비로 하여 10분 교반하고 젤라틴 용액을 투입한다. 10분내지 20분 후 나노 크기의 산화 인듐을 넣고 초산으로 pH를 5내지 6으로 조정하는 것이 바람직하다.젤라틴 용액은 제라틴과 순수의 무게비를 1:20으로 하고 70도에서 용해시키는 것이 바람직하다. 상기 전도성 물질이 부착된 카본의 전도성을 향상시키기 위하여 본 발명은 300~800℃의 온도를 가하여 1내지 4시간 동안 열처리 단계를 포함하는 전도성 물질이 부착된 카본의 제조 방법을 제공한다.상기 제조방법에서 열처리 온도는 300~800℃인 것이 바람직하다.In order to attach the nano-sized indium oxide to the carbon, carbon and pure water were stirred at a weight ratio of 1: 3 for 10 minutes, and a gelatin solution was added thereto. After 10 to 20 minutes, it is preferable to add nano-sized indium oxide and adjust the pH to 5 to 6 with acetic acid. The gelatine solution is preferably dissolved at 70 degrees with a weight ratio of gelatin and pure water 1:20. . In order to improve the conductivity of the carbon to which the conductive material is attached, the present invention provides a method for producing carbon with a conductive material including a heat treatment step for 1 to 4 hours by applying a temperature of 300 to 800 ° C. In the heat treatment temperature is preferably 300 ~ 800 ℃.
다음은 본 발명의 이해를 돕기 위하여 바람직한 실시예를 제시한다. 그러나 하 기의 실시예는 본 발명을 보다 쉽게 이해하기 위하여 제공되는 것일 뿐 발명이 하기의 실시예에 한정되는 것은 아니다.The following presents a preferred embodiment to aid the understanding of the present invention. However, the following examples are merely provided to more easily understand the present invention, and the invention is not limited to the following examples.
