Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a water-based two-component fluorocarbon conductive anticorrosion paint that can be used for surface coating of buildings and chemical equipment with high performance requirements, and can also be used for surface coating of outdoor large equipment, and its preparation method and The method of use overcomes the defects of the existing single-component water-based fluorocarbon paint such as poor weather resistance, poor adhesion and hardness, and no antistatic performance. The resulting paint film has excellent weather resistance, durability, water and oil repellency, and low temperature resistance. , chemical resistance, corrosion resistance, non-adhesion, pollution resistance and extremely low coefficient of friction, at the same time, it also has conductivity, which can effectively eliminate static electricity on the coating surface
