Temperature-resistant pressure-resistant anticorrosive paint for pipelines and preparation method of temperature-resistant pressure-resistant anticorrosive paint

The invention discloses a temperature-resistant, pressure-resistant and anticorrosive coating for pipelines and a preparation method of the temperature-resistant, pressure-resistant and anticorrosive coating, and relates to the technical field of engineering coatings. Comprising the following components in parts by weight: 50 to 60 parts of novolac epoxy resin, 5 to 10 parts of a curing agent, 6 to 8 parts of ethylene glycol diglycidyl ether, 2.6 to 3.3 parts of diethylenetriamine propyl trimethoxy silane, 2.2 to 3.5 parts of modified short carbon fibers, 0.9 to 1.2 parts of aluminum tripolyphosphate, 0.12 to 0.25 part of tourmaline and 0.02 to 0.35 part of phenolsulfonic acid. According to the anti-corrosion coating, the adsorption capacity and the porous characteristic of the tourmaline are firmly combined with all the components, the pressure resistance of the anti-corrosion coating is remarkably enhanced through combination and adsorption of the modified short carbon fibers and the tourmaline, and the ant
