Heatproof anticorrosion pigment

The invention relates to a heatproof anticorrosion pigment which comprises the following components in parts by weight: 16-21 parts of modified phenolic aldehyde neoprene, 15-18 parts of epoxy resin, 3-7 parts of tree ash, 11-16 parts of VAE (vinyl acetateethylene emulsion), 7-12 parts of padding, 8-15 parts of antioxidant, 6-8 parts of stabilizer, and 5-7 parts of accelerant. According to the heatproof anticorrosion pigment, the problem that a pipeline is eroded due to high temperature and long-term immersion in boiling water is solved, and the coating formed on the inner wall of the pipeline is high temperature resistant, has high antiseptic property, is thick and has good flexibility.
