Aqueous asphalt imitation anticorrosion coating for container chassis and preparation method thereof

Abstract

The invention discloses aqueous asphalt imitation anticorrosion coating for container chassis and a preparation method thereof. The aqueous asphalt imitation anticorrosion coating for container chassis comprises the following components in percentage by weight: 5 to 13 percent of running water, 46 to 62 percent of aqueous acrylic acid emulsion, 10 to 15 percent of rust resisting pigment, 15 to 22 percent of body filler, 0.6 to 1.0 percent of anti-settling agent, 0.05 to 0.2 percent of wetting dispersant reagent A, 0.2 to 1.0 percent of wetting dispersant reagent B, 4 to 6 percent of film-forming aid, 0.1 to 0.3 percent of defoaming agent, 0.2 to 0.4 percent of pH regulator, 0.4 to 0.8 percent of salt spray resistant aid, 0.1 to 0.2 percent of flash rust resistant agent and 0.1 to 0.7 percent of thickener. According to the invention, the flash rust resistant agent and the body filler are dispersed in the aqueous coating system together, so the coating has excellent anticorrosion performance; and the aqueous asphalt imitation anticorrosion coating does not contain harmful materials such as organic solvents and heavy metals, so the environment protection performance of the coating is high. And the coating makes construction simple, can be safely stored and has stable performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based asphalt-like anti-corrosion coating for container underframes and a preparation method thereof. Background technique [0002] Containers are special tools for international transportation and logistics, and most of them are steel structures. Since the transportation of containers is between the land and the sea, it is required to have strong corrosion resistance and temperature resistance (-40 ~ 70 ° C), and also requires good decoration, no discoloration, no chalking, and wear resistance , Scratch resistance, impact resistance, etc., and can withstand the test of harsh conditions. This puts forward higher requirements for the protection of metal structures in harsh corrosive environments. At present, asphalt anticorrosion coatings for domestic containers are mainly solvent-based coatings, which contain a large amount of VOC (Volatile Organic Compoμnds), most of ...
