▎ 摘　　要

NOVELTY - The film-making device has a rotating roller (1) whose outer surface is fixed with a film-forming base material (8). A heating device (2) and a nozzle (4) are located on different sides of the rotating roller. The nozzle sprays a film forming liquid on the surface of the film forming base material, where the heating device dries the film-form liquid sprayed on the film form material. The rotating roller is provided with a first rotating roller, a second rotating roller and a third rotating roller that are connected with each other. The heating device is connected with the heating roller. USE - Film-making device for preparing graphene heat conducting film. ADVANTAGE - The film making device uses the rotating device outer ring to joint the base material, which is convenient for taking film and improving efficiency. It uses the pneumatic atomizing nozzle to spray in the form of fan surface, the gas drives the oxidizing graphene solution, so as to effectively control the atomizing effect, it can more uniformly form the film and improve the heat conducting performance. The filtering device effectively removes impurities, the large grain diameter of the agglomerates and so on to the film forming effect, improving the film-forming effect and heat-conducting performance. High speed stirring is carried out before stirrer, the purpose is to reduce the stirrer speed stirring time, and improving the effect of high speed stirring in a short time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing heat conducting film by film-making device; (2) a graphene heat conducting film. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the film forming apparatus. 1Rotating roller 2Heating device 3Motor 4Nozzle 5Filter device 6Liquid pump 7Stirrer 8Film-forming base material
