Abstract

The invention discloses an anti-corrosive coating for a cement concrete crash-resisting wall. The anti-corrosive coating is prepared from the following raw materials: hydroxylated acrylic resin, epoxyresin, lauryl alcohol polyoxyethylene, mullite, polypropylene glycerol ether, polyimide, polymethylphenylsiloxane, a thickening agent, ethylene bisstearamide, ethoxylated aliphatic alkylamine, a silane coupling agent, propylene glycol monomethyl ether and calcium aluminum borosilicate. The invention also discloses the preparation method of the anti-corrosive coating for the cement concrete crash-resisting wall. The coating prepared by the preparation method disclosed by the invention has the advantages of good adhesion, capability of being well attached to the surface of the cement concrete crash-resisting wall, low possibility of peeling off, excellent alkali resistance, acid resistance and salt spray corrosion resistance; the anti-corrosion performance of the cement concrete crash-resisting wall is greatly improved and the service life of the cement concrete crash-resisting wall is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion coating for cement concrete anti-collision walls and a preparation method thereof. Background technique [0002] The guardrail design of large and medium-sized bridges in high-grade highways generally adopts cement concrete anti-collision walls. Cement concrete anti-collision wall is a kind of safety protection facility for highway bridges. With its unique structural form protruding toward the direction of driving, it can buffer the impact of vehicles, increase the sense of safety of driving, and reduce the damage of vehicles to the anti-collision wall. Obvious effect. Because the cement concrete anti-collision wall is exposed to the sun, rain and other environments for a long time during use, coupled with the carbonization of the concrete itself, the corrosion of the steel bars, etc., it will deteriorate and appear cracking, corrosion, peeling, swelling, Sof...
