▎ 摘 要
NOVELTY - Composite material comprises 95-99.67 wt.% component A and 0.33-5 wt.% component B, where component A comprises 82.6-93.4 wt.% activated anthracite, 3.3-8.7 wt.% binder, and 3.3-8.7 wt.% negative ion powder, and component B comprises 66.7-83.3 wt.% graphene and 16.7-33.3 wt.% surfactant. USE - Composite material. ADVANTAGE - The composite material has synergistic effect of components, and characteristics of high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, high adsorption capacity, easy regeneration, and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite material, which involves: (A) selecting anthracite and crushing it, kneading the binder, negative ion powder and anthracite to obtain a mixture A, extruding the mixture A into a carbon strip and cutting the carbon strip into a granular short carbon strip; (B) carbonizing the short carbon strip to obtain a water-free short carbon strip; (C) activating the anhydrous short carbon strip in a gas activator, and cooling to obtain component A; (D) mixing the graphene, surfactant, and solvent and stirring uniformly to obtain a graphene dispersion solution; and (E) mixing component A and graphene dispersion solution and heating for 1-4 hours at 40-80 degrees C temperature, then drying at 100-200 degrees C temperature for 5-15 hours to obtain the product.
