Description

technical field [0001] The present invention belongs to the improvement of surface coating materials. technical background [0002] In recent years, many people have carried out research and development, such as "rust paint" and "fluorocarbon paint" with anti-aging properties. But have not yet inquired so far to have high adhesion, good surface coating of corrosion resistance. Invention content: [0003] The present invention aims at the above problems and provides a nano zinc-aluminum modified epoxy-fluorocarbon coating with strong adhesion to the surface of the base material and good corrosion resistance. [0004] The present invention adopts following technical scheme: [0005] The present invention includes primer and top coating; [0006] The primer is composed of the following parts by mass: E-51 epoxy resin 80-100 parts, silicone resin containing Si-OH group 20-30 parts, particle size range 30-85nm, maximum average diameter D 50 = 1-2 parts of 45-65nm nano-zinc ...
