▎ 摘　　要

NOVELTY - Preparing aqueous graphene radiating coating comprises (a) adding 8 -12 pts. wt. graphene, 0.1-0.2 pts. wt. sodium lignin sulfonate into 50-60 pts. wt. aluminum dihydrogen phosphate solution, grinding and dispersing in a ball mill, drying, heating for high temperature processing, cooling, grinding, and discharging to obtain a pre-processed graphene, (b) adding 10-15 pts. wt. pre-processed graphene, 0.5-1 pts. wt. dispersant, 3-5 pts. wt. copper powder and 80-90 pts. wt. sodium silicate solution into a basket type sand mill, grinding and dispersing, and discharging to obtain a pre-dispersed slurry, (b) adding 90-110 pts. wt. pre-dispersed slurry, 1-3 pts. wt. alpha -alumina, 0.5-1 pts. wt. silicon nitride, 1-2 pts. wt. boron nitride, 0.1-0.5 pts. wt. thickening agent, 0.1-0.2 pts. wt. antifoaming agent, 0.5-1 pts. wt. anti-settling agent, 15-20 pts. wt. deionized water and 15-20 pts. wt. sodium tripolyphosphate into ball mill, ball milling, dispersing uniformly, discharging, and canning. USE - The method is useful for preparing aqueous graphene radiating coating. ADVANTAGE - The coating: is environment-friendly and easy to disperse, overcomes the problem of graphene segregation and sedimentation, and has good affinity, excellent heat dissipation performance and heat resistance performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the aqueous graphene radiating coating, prepared by the above mentioned method.
