NOVELTY - Graphene heat conductive coating comprises 13-17 pts. wt. graphene, 4-9 pts. wt. nano carbon material, 14-20 pts. wt. lauryl betaine, 25-30 pts. wt. N-methylpyrrolidone, 40-60 pts. wt. aqueous polyurethane, 5-10 pts. wt. propylene glycol alginate, 2-5 pts. wt. sodium sulfate and 50-100 pts. wt. water. USE - Used as graphene heat conductive coating. ADVANTAGE - The coating has excellent thermal conductivity, heat resistance and adhesion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene heat conductive coating, comprising (i) mixing graphene, nano carbon material and water, and magnetically stirring for 10-20 minutes to obtain suspension, (ii) adding lauryl betaine and N-methylpyrrolidone into the suspension, adjusting the pH to 6-8, and magnetically stirring for 20-40 minutes, (iii) adding aqueous polyurethane and sodium sulfate into obtained suspension, magnetically stirring for 10-20 minutes, then adding propylene glycol alginate, magnetically stirring for 10-20 minutes, dispersing for 20-40 minutes in a high speed shear disperser, and ultrasonically dispersing for 10-20 minutes to obtain final product.
