Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to a corrosion-resistant modified coating.
Background
In the field of building material corrosion prevention, the traditional pure epoxy coating has higher requirements on the surface treatment of a base material, and particularly, the control on the moisture and salt content of the surface of the base material is strict. When the humidity of the construction environment is more than 65 percent or the environmental temperature is lower than the dew point by 3 ℃, the coating construction is not recommended, and the main reason is that the moisture in the air is easy to be condensed on the base material under the condition, so that the base material is in a wet state. When the surface of the base material is in a wet state, the greatest problems are that the adhesion between the coating and the base material is poor, the surface of a coating film is sticky, and the epoxy and amine curing agent is insufficiently cured, and the excellent adhesion is a precondition for the coating to have good corrosion resistance. In the fields of underwater pipelines, mines, tunnels, water storage pools, water gates, reservoirs and the like, anticorrosive coatings which can be cured in underwater construction are required. Obviously, conventional epoxy coatings do not meet the requirements of the above-mentioned fields. Therefore, it is highly desirable to provide a corrosion-resistant modified coating material that satisfies the requirement of excellent corrosion resistance.
