▎ 摘　　要

NOVELTY - Antistatic graphene coating comprises component (A) comprising 40-60 pts. wt. water-based epoxy resin, 5-10 pts. wt. filler and 15-30 pts. wt. additives, component (B) comprising 0.5-2 pts. wt. antistatic system, and component (c) comprising 20-30 pts. wt. water-based epoxy resin curing agent and 10-30 pts. wt. diluent. The antistatic system comprises graphene aqueous dispersion, carbon nanotube aqueous dispersion and aqueous dispersant. The graphene aqueous dispersion and the carbon nanotube aqueous dispersion are mixed in a weight ratio of 2: (0.5-1), and the weight of the aqueous dispersant is 1-10% of the total weight of the graphene aqueous dispersion and the carbon nanotube aqueous dispersion, and the graphene aqueous dispersion is obtained by a high-pressure homogeneous liquid phase exfoliation method. USE - Anti-static graphene paint is used for factory workshop and ground construction of laboratory, floor paint, floor paint for factory, ground construction, and anti-corrosion paint. ADVANTAGE - The anti-static graphene paint has excellent dispersion effect, stable conductive, non-conductive blind spot of antistatic and large batch low cost of graphene coating, and avoids agglomeration problem.
