Abstract
Disclosed is a method for preparing graphite film, comprising steps as follows: 1) winding; 2) carbonizing at a low temperature; 3) graphitizing at a high temperature; 4) unwinding and feeding, winding up the electrographite film semi-finished product and flexible graphite paper separately; 5) calendaring to press the electrographite film semi-finished product against release film or protective film; 6) winding up and packaging. The winding process comprises steps as follows: a. winding high temperature resistant elastic material around the graphite cylinder core; b. bonding macromolecular film to flexible graphite paper, and then winding around the graphite cylinder core based on step a; c. when the macromolecular film and flexible graphite paper wound in step b reach the predetermined thickness, securing with carbon cord.
