The invention discloses an anti-corrosion anti-permeability fire-retardant coating comprising the following raw materials by weight: 50-80 parts of Portland cement, 10-15 parts of polymer emulsion, 15-20 parts of expanded perlite, 10-20 parts of talcum powder, 3-6 parts of granite, 10-15 parts of graphite powder, 5-7 parts of magnesium hydroxide, 5-7 parts of aluminum hydroxide, 0.3-1.5 parts of silicon alkyl powder, 3-5 parts of pentaerythritol, 2-3 parts of a concrete expansion agent, 6-8 parts of mica powder, 1-3 parts of aluminum dihydrogen tripolyphosphate and 1-3 parts of zinc borate. The anti-corrosion anti-permeability fire-retardant coating is used for under coal mine well coal seams, has the advantages of excellent fire-retardant heat-insulating property, good coal adhesion, good anti-permeability waterproof property, good antistatic property, good water, acid and alkali and salt corrosion resistance, storage stability, no toxicity and environmental protection, and the like, and can meet the requirements of irregularity of the surface of the coal seams and self deformation of the coal seams, and crack phenomenon is not easy to cause.
