▎ 摘　　要

NOVELTY - A graphene modified nano heat insulating paste comprises 5-15 pts. wt. nano antimony tin oxide powder, 10-20 pts. wt. graphene aqueous dispersion, 1-5 pts. wt. dispersant, 50-80 pts. wt. deionized water, and 1-3 pts. wt. defoamer. USE - Graphene modified nano heat insulating paste used as heat insulation agent, antistatic agent and glass window. ADVANTAGE - The graphene modified nano heat insulating paste has high visible light transmittance, high infrared blocking rate, high adhesion force and high hardness and is prepared using less equipment investment at low cost by simple and environmentally-friendly process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene modified nano heat insulating paste, which involves adding nano- antimony tin oxide powder to deionized water, stirring, adding graphene aqueous dispersion and certain amount of dispersant and defoamer, decentralizing, adding remaining dispersant, and stirring.
