Abstract

본 발명은 핏치류를 원료로 하여 기계용 부품, 전기부품 및 화학장치 구조용등에 사용되는 탄소성형체를 제조하는 방법에 관한 것으로, 핏치에 적정량의 산소를 함유시키고 이를 원료로 이용하여 급속탄화하므로서, 고밀도 및 고강도의 특성을 갖는 탄소성형체의 제조방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing a carbon molded body used for the construction of machinery parts, electrical parts, chemical devices, etc. using pitches as a raw material, and contains a suitable amount of oxygen in the pitch and rapidly carbonizes it as a raw material, And to provide a method for producing a carbon molded article having a high strength characteristics, the purpose is.

상기한 목적을 달성하기 위한 본 발명은 탄소성형체의 제조방법에 있어서, 연화점이 280℃ 이상인 핏치를 100㎛ 이하인 분말로 분쇄한 후, 산소 분위기하에서 200-270℃에서 0.5-24시간 산화처리하여 산화핏치 분말을 제조한 다음, 상기 산화핏치 분말을 100-2000㎏/㎠의 압력으로 가압성형한 후, 불활성 분위기에서 분당 50-500℃의 승온속도 범위로 900-1500℃의 온도 범위까지 승온하여 탄화하는 것을 포함하여 이루어지는 탄소 성형체의 제조방법에 관한 것을 그 요지로 한다.In the present invention for achieving the above object, in the method for producing a carbon molded article, the pitch of the softening point of 280 ℃ or more pulverized to a powder of 100 ㎛ or less, and then oxidized by oxidation treatment at 200-270 ℃ 0.5-24 hours under oxygen atmosphere After the pitch powder was prepared, the oxide pitch powder was press-molded at a pressure of 100-2000 kg / cm 2, and then carbonized by heating up to a temperature range of 900-1500 ° C. at a temperature rising rate range of 50-500 ° C. per minute in an inert atmosphere. The summary relates to the manufacturing method of the carbon molded object which consists of doing the thing.
