▎ 摘　　要

NOVELTY - Insulating paste comprises 47.0-53.0% nano-oxide graphene dispersant, 47.4-52.45% antimony tin oxide nanopowder dispersant, and 0.05-0.10% silicone coupling agent. The nano-oxidized graphene dispersion comprises 1.5-4.0% nano-oxide graphene, 1.0-1.5% dispersant and 44.5-47.5% deionized water. The antimony tin oxide nanopowder dispersants comprises 0.750-2.75% first antimony tin oxide nanopowder, 0.5-1.0% second dispersant and 46.15- 48.70% deionized water. USE - Insulating paste. ADVANTAGE - The paste has high transparency degree, strong adhesive, good insulation effect, ideal insulation performance, and long-term uniform stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of insulating paste comprising weighing 1.0-1.5% first dispersant and 44.5-47.5% deionized water, adding nano-oxide graphene and first dispersing agent, taking deionized water, mixing, grinding, and subjecting ultrasonic dispersant to obtain nano-oxide graphene dispersion; weighing 0.750 -2.75% antimony tin oxide nanopowder, 0.5-1.0% second dispersant, and 46.15-48.70% deionized water, adding second dispersant, taking deionized water, mixing, grinding, and subjecting ultrasonic dispersion, get antimony tin oxide nanopowder dispersant; and forming siloxane coupling agent at weight ratio of 0.05-0.10 wt.% based on total weight of heat-insulating paste, and heat-mixing siloxane coupling agent with prepared nano-oxidized graphene dispersant and antimony tin oxide nanopowder dispersant to obtain heat-insulating slurry.
