Anti-corrosion paint, application thereof and pipeline coating

The invention provides anti-corrosion paint, an application thereof and a pipeline coating. The anti-corrosion paint comprises a first component and a second component, wherein the first component comprises polyether amine, first modified polyaspartic acid ester and second modified polyaspartic acid ester, and the second component comprises isocyanate and/or a prepolymer thereof. Compared with traditional polyaspartic acid ester urea paint, by means of the added polyether amine component, ether linkage with good flexibility can be introduced in a final cured resin molecular chain, and the chain length and the low-temperature toughness of the cured resin molecular chain are improved; by means of added second modified polyaspartic acid ester, increase of the heat-resistant temperature as well as improvement of weather resistance, smoothness and scratching resistance of the coating is facilitated. When the anti-corrosion paint is matched with a fusion bonded epoxy powder bottom coating, the problems of stripping and joint coating stripping in application of a polyethylene anti-corrosion layer of a conventional pipeline as well as poor high temperature cathodic stripping resistance of a polyuria coating can be solved very well.
