The invention discloses an environmentally-friendly anticorrosive treatment method for a household wood slab. The method comprises the following steps: 1) cutting and polishing the wood slab smoothly;2) smearing wax oil to the surface of the wood slab and airing the wood slab; 3) spraying an anticorrosive coating to the surface of the wood slab, drying the wood slab, coating the surface of the wood slab with a preservative film layer, putting the wood slab in a steam room, introducing high-temperature steam, naturally cooling the wood slab, and drying the wood slab; 4) spraying a finishing coat to the wood slab, airing the wood slab, heating the wood slab to 75-80 DEG C, quickly taking the wood slab out and spraying the anticorrosive coating, covering the surface of the wood slab with wetcloth, wrapping the wood slab with a preservative film, and heating the wood slab to 100-110 DEG C; and 5) brushing a protective wax layer to the wood slab to obtain a finished product wood slab. According to the environmentally-friendly anticorrosive treatment method, the anticorrosive coating is enabled to penetrate into the interior of the wood slab surface, and the finishing coat layer and the anticorrosive coating layer permeate and fuse each other, so that the bonding and adhesive capacity of the anticorrosive coating and the wood slab is improved greatly, and meanwhile, the bonding force between the finishing coat and the anticorrosive coating is improved, and the anticorrosive effect is improved.
