High-solid low-viscosity color slurry, preparation method of high-solid low-viscosity color slurry, and heat radiation paint

The invention provides high-solid low-viscosity color slurry, which is prepared from the following ingredients in parts by mass: 3 to 6 parts of modified graphene, 1 to 2 parts of modified carbon nanometer tubes, 0.5 to 2 parts of modified graphene quantum dots, 0.5 to 1 part of viscosity reducers, 0.25 to 0.5 part of antifoaming agents and 20 to 40 parts of deionized water. The modified grapheneis obtained by modifying the graphene through comb-shaped block polymers; the modified carbon nanometer tubes are obtained by modifying carbon nanometer tubes through sulfonate polymers; the graphenequantum dots are obtained by modifying graphene quantum dots through cyclodextrin. The color slurry has the advantages of high solid content, low viscosity, high storage stability and wide applicationrange. The color slurry can be added into an epoxy resin system, an acrylic resin system and a polyurethane system to obtain heat radiation paint; the heat conduction coefficient of the heat radiation paint is high; the heat r
