Abstract

The invention relates to a high-temperature electric heating film of a flexible nano-carbon composite material and a preparation method of the high-temperature electric heating film. The high-temperature electric heating film is prepared from electric heating film slurry and glass fiber cloth; the high-temperature electric heating film is characterized in that the electric heating film slurry is prepared from a solid material and a solvent at the mass percent of (20%-40%):(80%-60%), wherein the solid material is prepared from graphite of which the particle sizes are within 50nm, carbon black, silver, zinc oxide and a rare-earth material at the mass ratio of 5:2:1:2:0.5; and the solvent comprises xylene, dimethylformamide, polyamide ester and a polyimide polymer solution at the mass ratio of 1:4:1:4. The problems of poor high temperature resistance, flame retardant property and film adhesion in raw materials are solved. The electric heating film has good high-temperature (400 DEG C) uniformity, high heating efficiency and good performance and stability.

Description

Technical field [0001] The invention relates to a heating film, in particular to a flexible nano-carbon composite material high-temperature electric heating film and a preparation method thereof.
