▎ 摘  要

NOVELTY - The coating liquid includes raw material with 10-30 wt. % zinc, 1-10 wt. % aluminum, 2-30 wt. % film former, 40- 70 wt. % solvent, 0.1-10 wt. % additive, 0.1-5 wt. % thickener, 0.001-15 wt. % graphene, and 0.1-10 wt. % filler. The filler is a phosphate, a molybdate and a tungstate. The solvent is a mixture of water and an organic solvent, the water is deionized water, and the solvent is an ethylene glycol, n-butanol, polyethylene glycol, propylene glycol methyl ether acetate, and dipropylene glycol dimethyl ether. The film forming agent is a silane coupling agent, a titanate coupling agent, a borate coupling agent, and an aluminate coupling agent. USE - Graphene-modified aqueous zinc-aluminum anticorrosive coating liquid. ADVANTAGE - Improves uniformity of the conduction of the zinc-aluminum coating, which contributes to the establishment of the entire coating corrosion inhibition network. Obtains the granularity since the raw materials are premixed twice. Ensures excellent corrosion resistance of the cured coating layer, since the pre-mixed material with a fine microstructure obtains a liquid-stable stable coating liquid when mixed with the remaining raw materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for using the graphene-modified aqueous zinc-aluminum anticorrosive coating liquid.
