DETAILED DESCRIPTION - Aqueous electric heating material comprises multi-layer graphene powder, carbon nanotube powder, adhesive, dispersant, plasticizers, drying agent and filler. The mass ratio of multi-layer graphene powder and carbon nanotube powder is 1:1-5. The adhesive is an aqueous epoxy resin and aqueous acrylic resin in the mass ratio of 1:1. The dispersant is sodium hexametaphosphate. The plasticizer is maleic acid. The drying agent is aluminum stearate. The amount of adhesive, dispersant, plasticizers and drying agent are 1-1.2 wt.% the total weight of the mixed powder. The filler is carbon black. The amount of filler added is 20-40 wt.% the total weight of the mixed powder. An INDEPENDENT CLAIM is also included for preparing aqueous electric heating material comprising uniformly mixing multi-layer graphene powder and carbon nanotube powder, uniformly mixing with surfactant in the reaction kettle, where the surfactant comprises 90-95 wt.% ethanol and pure water in the mass ratio of 1:1, soaking for 20-40 minutes for clarification treatment, pre-washing, introducing into dispersion stirrer, adding adhesive, stirring at 1000-2000 rotations/minute for 20-30 minutes, adding dispersant, plasticizers, drying agent and fillers, mixing uniformly, and grinding for 20-40 minutes, filtering and packaging, to obtain the final product.
