The invention relates to a coating for monitoring the corrosion degree of pipelines or equipment, in particular to a corrosion monitoring coating and belongs to the technical field of corrosion monitoring. The corrosion monitoring coating is prepared from a hydrogen-sensitive chromatic material and a film forming material in percentage by mass as follows: 1%-50% of the hydrogen-sensitive chromatic material, 1%-10% of a curing agent and the balance of epoxy resin through mixing. The corrosion monitoring coating has the benefits as follows: the hydrogen-sensitive chromatic material is mixed in the film forming material and reacts with atomic hydrogen, so that the color of the corrosion monitoring coating is changed, the corrosion degree of local corroded positions of the pipelines or equipment is recognized, and a perspective coating effect is produced for local corrosion; a transparent material capable of coating outer surfaces of the pipelines to form coatings is selected as the film forming material, and interference of the color of the film forming material to change of the color of the corrosion monitoring coating is prevented; the corrosion monitoring coating can also provide reference for material selection of the pipelines or equipment under the hydrogen sulfide containing condition.
