Development and performance index of epoxy zinc-rich primer for heavy corrosion environment
2021-04-08
Through strong bond coating modified by epoxy zinc rich primer is dedicated to severely corrosive environment conditions, warranty period is longer, and often is not convenient to maintenance areas as anti-corrosion primer is used, the invention of the epoxy resin modified epoxy resin by hydroxyl and benzene anhydride reaction, the introduction of high polarity carboxyl, epoxy resin itself became a strong dispersion ability of dispersant, can be spread efficiently and chelating graphene, make graphene and chelating resin, evenly dispersed in the epoxy zinc rich primer system, to achieve the best effect of antisepsis, in addition, the lamellar structure of graphene make epoxy zinc rich primer paint film is more compact,Corrosion resistance is further enhanced by increasing the length of the path of corrosive media.
