Flue anticorrosive paint for pulverized coal boiler

The invention discloses flue anticorrosive paint for a pulverized coal boiler. The flue anticorrosive paint consists of the following components in parts by weight: 20-25 parts of nano micro powder, 15-20 parts of ceramic microbeads, 9-10 parts of silicon carbide, 10-15 parts of boron nitride, 6-8 parts of fine grain aluminum oxide, 8-10 parts of superfine zinc oxide, 20-25 parts of titanium oxide and 1-3 parts of a wear-resisting agent. The flue anticorrosive paint is good in corrosion resistance, a pipeline can be well prevented from being corroded by media such as corrosive gases in fume, a painted layer is long in service life and good in durability, a damaged painted layer can be conveniently repaired, and the maintenance cost of the pulverized coal boiler can be effectively lowered.
