▎ 摘　　要

NOVELTY - Anti-freeze type aqueous based graphene electrothermal slurry comprise 28-40 wt.% water, 10-25 wt.% graphene, 5-15 wt.% carbon black, 20-40 wt.% aqueous emulsion, 10-15 wt.% propylene glycol and 6-12 wt.% aqueous auxiliary agent. USE - Used as an electrothermal slurry comprising grapheme and carbon black. ADVANTAGE - The electrothermal slurry has freezing point less than -20 degrees C; reduces indoor and outdoor air quality and environment; reduces liver, kidney and nervous system damage for workers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing anti-freeze type aqueous based graphene electrothermal slurry comprising (a) taking the raw materials, (b) sequentially adding the liquid materials (including propylene glycol) in the reaction kettle, dispersing for 5-10 minutes, uniformly stirring, adding graphene and carbon black powders into the reaction kettle by vacuum pumping, dispersing at 2000 revolutions/minute for 1 hour, stopping the dispersion and completing the premixing step, where soaking the dispersing disc of the dispersing machine in water, (c) transferring the premixed material from the reaction kettle to the grinding machine for grinding, performing particle size detection by quality inspector, completing the grinding to obtain a slurry, when after passing the inspection, (d) taking the required emulsion and aqueous auxiliary agent, adding to the grounded slurry, dispersing at 1600-2000 revolutions/minute for 30-40 minutes, inspecting the sampler, stopping the dispersion after passing the test and (e) filling, labeling and warehousing after passing the inspection.
