Anti-rust composition for metal surface and a method of anti-rust treatment on metal surface

Abstract

Described herein is an anti-rust composition for metal surfaces including: a) 30% to 80% by weight of water-soluble or water-dispersible acrylic resin and/or urethane resin; b) 0.1% to 10% by weight of epoxysilane and/or vinylsilane; c) 0.1% to 3% by weight of silicone surfactant and/or fluorosurfactant; d) 0.1% to 10% by weight of alcohol and/or ether; and e) water, where the weight percentage of each component is based on the total weight of the aqueous composition. Also described herein is an anti-rust treatment method on a metal surface including steps of i) coating the invented anti-rust composition onto the metal surface and ii) drying the coating layer at a temperature from 60° C. to 150° C. Also described herein is an anti-rust treated coil steel obtained by the anti-rust treatment method.
