The invention discloses a marine antirust paint and a preparation method thereof. The component A of the antirust paint is prepared by adding 5-15 parts by mass of chlorinated rubber, 10-16 parts by mass of calcium carbonate, 45-60 parts by mass of talcum powder, 18-27 parts by mass of iron oxide red, 22-30 parts by mass of xylene, 9-15 parts by mass of n-butyl alcohol, 6-12.5 parts by mass of a functional auxiliary agent, 20-28 parts by mass of tackifying epoxy resin and 45-60 parts by mass of an antirust pigment into 100 parts by mass of E51 epoxy resin, and grinding after well dispersing. In addition, the component B of the antirust paint adopts 75-100 parts of a modified amine curing agent or a polyamide curing agent. The antirust paint is excellent in toughness and high in impact resistance; the surface drying speed and the hard drying speed are high, and the processing property is excellent; and meanwhile, the antirust paint has good salt spray resistance, and can meet the use requirements of universal
