▎ 摘　　要

NOVELTY - Coating comprises humic acid, particles of an anti-corrosive pigment or sacrificial metal, and a binder resin. The humic acid occupies a weight fraction from 0.1-50 wt.% based on the total coating weight. USE - Anti-corrosion coating. ADVANTAGE - The corrosion resistant coatings protect metal components against degradation due to moisture, salt spray, oxidation, or exposure to a variety of environmental or industrial chemicals. Anti-corrosion coating enables added protection of metal surfaces and acts as a barrier against the contact between corrosive agents and the metal substrates to be protected. In addition to corrosion prevention, many of the coatings also provide improved abrasion resistance, non-stick performance and chemical protection. Coatings with anti-corrosive properties ensure metal components have the longest possible lifespan. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an object or structure, where anti-corrosive pigment or sacrificial metal is selected from the group consisting of aluminum, chromium, zinc, beryllium, magnesium, an alloy thereof, zinc phosphate, and combinations; and (2) a method of inhibiting corrosion of a structure or object having a surface, which involves covering at least a portion of the surface with an anti-corrosive coating comprising 0.1-50 wt.Anti-corrosion coating% by weight of humic acid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view flow chart showing the most commonly used process for producing oxidized graphene sheets that entails chemical oxidation/intercalation, rinsing, and high-temperature exfoliation procedures.
