Problems solved by technology

[0002] With the current rapid economic development, the mechanical properties and corrosion of outdoor metals have attracted more and more attention. Due to the harsh working environment for a long time, especially in some working environments in areas exposed to the sun for a long time, the anti-corrosion and mechanical measures of metals are not enough. Avoid, the general practice is to paint on the metal surface, but the corrosion resistance and mechanical properties of conventional epoxy coatings cannot meet the needs of harsh working environments. How to prepare a epoxy coating with strong adhesion, good corrosion resistance and excellent mechanical properties Coatings for outdoor metals have become a technical problem that needs to be solved at present
