▎ 摘　　要

NOVELTY - Tungsten bronze heat-insulating particles comprises tungsten bronze, and a carbon material layer coated on the surface of the tungsten bronze; the carbon material layer includes graphene and/or carbon nanotubes. USE - Used as tungsten bronze heat-insulating particles. ADVANTAGE - The tungsten bronze heat-insulating particles has improves thermal conductivity, improves infrared blocking ability, increases conductivity, and has good transparency and reduces carbon substance is first oxidized. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing tungsten bronze heat-insulating particles comprising (1) performing an oxidation reaction on a carbon material and an oxidizing agent to obtain an oxidizing carbon material solution, where the carbon material includes graphene and/or carbon nanotubes; and (2) mixing the oxidizing carbon substance solution with a tungsten bronze solution, adding a reducing agent, and reacting, A tungsten bronze heat insulating particle which is prepared by above method. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged schematic view of the structure of tungsten bronze heat-insulating particles.
