Abstract

The invention discloses a zinc-rich steel structure anticorrosion coating. The coating comprises, by weight, 20-30 parts of acrylic acid modified resin, 10-20 parts of bisphenol A epoxy resin, 5-10 parts of diphenol propane epoxy resin, 4-10 parts of nanometer zinc oxide, 15-20 parts of zinc powder, 2-8 parts of titanium dioxide, 8-15 parts of ammonium polyphosphate, 1-5 parts of pentaerythritol, 10-15 parts of a siloxane grafted polymer, 1-5 parts of expandable graphite, 1-3 parts of cyclohexanone, 5-10 parts of ethylene triamine, 0.1-0.3 parts of manganese acetate and 20-25 parts of deionized water. The coating is rich in zinc, is anticorrosive, and has very good anticorrosive performance; an ester bond, an epoxy group and other structures contained in the coating make the coating have good adhesion with a steel structure; and the coating also has the advantages of good waterproof property, excellent wear resistance, excellent impact resistance, and excellent mechanical performances.

Description

technical field [0001] The invention belongs to the field of steel structure protection, and in particular relates to a zinc-rich steel structure anticorrosion coating. Background technique [0002] Most of the steel structures made of steel are exposed outdoors for a long time, some are placed underwater or underground, and are easily corroded and rusted by external factors. Therefore, it is necessary to coat a layer of anti-corrosion paint on the surface of the steel structure. to protect the steel structure. The field of steel structure anticorrosion mainly includes zinc cathodic protection, epoxy resin protection, polyurethane protection, etc., which are mostly used in the field of long-term anticorrosion of steel. The existing coatings for steel structures on the market have short anticorrosion periods and poor water resistance, which cannot meet people's needs. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides ...
