Abstract

The invention discloses a two-component carbon nanotube type epoxy zinc-rich coating, which is composed of a paint component and a curing agent component. The two components are packed. The coating ischaracterized by being prepared from the following raw materials in percentage by weight: 30 to 40wt% of epoxy resin, 5 to 8 wt% of xylene; 1 to 3 wt% of isobutanol; 0.3 to 1 wt% of polyamide wax; 22.3 to 27.5 wt% of a pigment and filler; 30 to 60 wt% of zinc powder; 0.1 to 0.5 wt% of an organic silicon polymer; and 2 to 10 wt% of a carbon nanotube; wherein the curing agent component is preparedfrom the following raw materials in percentage by weight: 10-20 wt% of xylene; 15 to 25 wt% of isobutanol; 15 to 20 wt% of phenolic aldehyde ammonia; 2 to 6 wt% of propylene glycol monomethyl ether; 5to 10 wt% of epoxy resin; and 20 to 50 wt% of modified polyamide. The product blank in the field of anticorrosive paints is filled, and the anticorrosive performance can be improved by 2-3 times compared with that of a conventional epoxy zinc-rich coating.
