METHOD FOR PRODUCING GRAPHITE COMPOSITE FILM
본 발명은 롤에 권부(卷付)한 그래파이트 필름을 권출(卷出)하여, 다른 롤로 권취(卷取)하기까지의 사이에, 당해 그래파이트 필름을 라미네이트하는 공정을 포함하고, 그래파이트 필름이 제1롤과 접촉 개시하는 점과 제1롤의 중점과 제1롤/제2롤의 접점이 이루는 각도 b가 5도 이상인 것을 특징으로 하는 그래파이트 복합 필름의 제조 방법에 관한 것이다.
A graphite film showing an extremely low average tearing force is more likely to suffer from various kinds of defects, such as splitting, winding deviation, wrinkling, and poor dimensional accuracy, in a step of producing the graphite film and in a step of processing the graphite film. However, these defects can be prevented by using a graphite film that satisfies the following requirements: 1) having an average tearing force of not more than 0.08 N as determined by Trouser tear method in accordance with JIS K7128; and 2) having sag of not less than 5 mm and not greater than 80 mm as determined by a method of film windability evaluation in accordance with JIS C2151.
