Abstract

The invention discloses an anticorrosive tough coating material for an outdoor communication tower, and a preparation method thereof, wherein the anticorrosive tough coating material is prepared fromthe following raw materials by weight: 12-18 parts of a polytrifluorochloroethylene resin, 35-45 parts of a bisphenol A type epoxy resin, 8-12 parts of polyphenylmethylsiloxane, 2-6 parts of alpha,omega-dihydroxy polydimethylsiloxane, 2-6 parts of amino-modified polysiloxane, 2-6 parts of hexamethyldisilazane, 2-6 parts of gas-phase nanometer silicon dioxide, 7-11 parts of silicon carbide short fibers, 12-16 parts of mica iron oxide powder, 2-8 parts of xylene, 10-20 parts of an acetone aqueous solution and 1-3 parts of a polyamine mixed curing agent. According to the invention, the prepared anticorrosive tough coating material has excellent anticorrosive performance, weather resistance and good elasticity; and by coating the communication tower with the anticorrosive tough coating material, the coating is compact, has excellent anticorrosive, anti-aging, hydrophobic, stain-resistant and impact-resistant effects, can well adapt to severe environments, and effectively prolongs the service life of the communication tower.

Description

technical field [0001] The invention relates to the technical field of coating compositions, in particular to an anti-corrosion tough coating for outdoor communication towers and a preparation method thereof. Background technique [0002] Most of the communication towers in my country are mainly installed outdoors, which are exposed to wind, sun and rain, and are easily corroded. In recent years, the environment where communication towers are located has become more and more harsh, and the rate of corrosion has become faster and faster. Strong acid and alkali environment, high salt spray environment, high temperature difference environment and high humidity environment all pose severe challenges to the use effect and lifespan of traditional anti-corrosion coatings, especially in high latitude and coastal areas, where the temperature difference between day and night and four seasons are large. Under normal circumstances, the steel structure will continue to undergo expansion ...
