▎ 摘　　要

NOVELTY - Composition includes expanded graphite, graphene powder, dispersant, water-based viscous resin, substrate wetting agent and defoamer. The dispersant is selected from dipropylene glycol butyl ether, dibutyl adipate, dipropylene glycol methyl ether acetate, povidone K30 and acrylic block copolymer. USE - Composition used in heating materials. ADVANTAGE - The composition effectively reduces production cycle, has low square resistance value, good heating effect, and good stability and efficient preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composition, which involves: (A) mixing and dispersing expanded graphite, deionized water and dispersant to obtain a graphene slurry with a solid content of 3-8%; (B) miixng water-based viscous resin with the dispersant to obtain the water-based viscous resin slurry; and (C) mixing the graphene slurry, the aqueous viscous resin slurry and the defoaming agent to obtain the product.
