NOVELTY - Manufacturing graphene thermally conductive thick film involves introducing the grapheme into the dispersion roller mechanism through the feed port for dispersion coating to form a semi-finished film cloth. The dispersed roller mechanism is formed by four rollers arranged in a cross shape. The semi-finished film cloth formed after one-time coating is sent to the first drying furnace for drying and curing, and an inner layer forming film is formed after curing. The inner layer formed film is introduced into the secondary coating roller mechanism, and the surface of the inner layer formed film is coated with graphene slurry for secondary coating to form a thickened semi-finished film. The secondary coating roller mechanism comprises two vertically arranged rollers. The thickened semi-finished film after the second coating is sent to the second drying furnace, and then dried and cured to form a thickened mold after curing. USE - Method for manufacturing graphene thermally conductive thick film. ADVANTAGE - The method enables to manufacture graphene thermally conductive thick film with high production efficiency and good quality in a simple, cost-effective and easy manner. DETAILED DESCRIPTION - Manufacturing graphene thermally conductive thick film involves introducing the grapheme into the dispersion roller mechanism through the feed port for dispersion coating to form a semi-finished film cloth. The dispersed roller mechanism is formed by four rollers arranged in a cross shape. The semi-finished film cloth formed after one-time coating is sent to the first drying furnace for drying and curing, and an inner layer forming film is formed after curing. The inner layer formed film is introduced into the secondary coating roller mechanism, and the surface of the inner layer formed film is coated with graphene slurry for secondary coating to form a thickened semi-finished film. The secondary coating roller mechanism comprises two vertically arranged rollers. The thickened semi-finished film after the second coating is sent to the second drying furnace, and then dried and cured to form a thickened mold after curing. The thickened film after secondary drying is introduced into the calendering roller mechanism, which is calendered to form a finished thermally conductive thick film. The calendering roller mechanism has two vertical rollers that are arranged in the rotation directions of the two rollers are opposite. The finished thermal conductive thick film is introduced into the collecting roller to collect into a tube.
