The invention relates to a black paperboard printing ink corrosion prevention printing method and a black paperboard finished product, the black paperboard finished product comprises a black paperboard and a styrene-acrylic emulsion touch layer formed on the black paperboard, and the styrene-acrylic emulsion touch layer is prepared by curing the following components: styrene-acrylic emulsion, water-based resin, an auxiliary agent and water. According to the black paperboard finished product, the styrene-acrylic emulsion touch layer is formed on the surface of the black paperboard, so that a coating is formed after curing, the styrene-acrylic emulsion has waterproof and ink-proof effects, a coating film formed after curing of the water-based resin has a corrosion-resistant effect, and an excellent corrosion-resistant effect is formed. The black paperboard contains carbon elements, so that the paper is strongly acidic, the black paperboard can corrode ink on the surface layer after a long time, the styrene-acry
