Abstract

The invention discloses a two-dimensional nano low-surface-treatment graphene anticorrosive primer and a preparation method thereof. The two-dimensional nano low-surface-treatment graphene anticorrosive primer is prepared from, by mass, 30-40wt% of epoxy resin, 5-8wt% of xylene; 1-3wt% of isobutanol; 0.3-1% of polyamide wax; 22.3-27.5wt% of a pigment and filler; 5-8wt% of zinc phosphate; 0.1-0.5wt% of an organosilicon polymer; 10-30wt% of two-dimensional nano graphene; and 12-15wt% of a curing agent. Different from a preparation formula and a preparation method adopting an epoxy system and ananti-rust pigment in the conventional technology, the graphene anticorrosion primer prepared by the invention possesses the anti-corrosion performance improved by 1-2 times compared with that of a conventional anti-corrosion paint.
