Description

technical field [0001] The invention relates to an anticorrosion coating. Background technique [0002] For some substrates, when they are exposed, they are easily vulcanized due to the erosion of substances in the air, which affects the mechanics, heat resistance, weather resistance, wear resistance and corrosion resistance of the substrate. In response to this technical problem, many people are now studying how to reduce the vulcanization of the substrate. Wherein a kind of mode is to spray paint on base material, disclose a kind of anti-vulcanization coating as in the patent literature of application number 200610078245.1, although a lot of people are researching the coating of this aspect now, but the anti-sulfurization of coating still has Room for improvement. For coatings, if the anti-corrosion performance is poor, the validity period of the coating is difficult to guarantee. Contents of the invention [0003] In order to improve anti-sulfur performance and anti-...
