The invention provides a short-process preparation method of an anti-corrosive wood material with a chemical plated Ni-W-P ternary alloy layer on the surface and relates to a wood chemical plating method. The short-process preparation method is provided for solving the technical problems that the stability of a plating solution is poor, the plating speed is low and the plating performance is poorthrough an existing method of plating a Ni-W-P ternary alloy plating on the wood surface. The short-process preparation method comprises the steps of 1, drying a wood board, 2, conducting activation,3, preparing a plating solution through nickel sulfate, sodium tungstate,. Sodium hypophosphite, sodium citrate, lactic acid and ammonium chloride, and 4, putting the wood board into the plating solution to be subjected to chemical plating to obtain the anti-corrosive wood material with the chemical plated Ni-W-P ternary alloy layer on the surface. The deposition rate of the nickel-tungsten-phosphorus plating of the anti-corrosive wood material is 0.08-0.11 g/cm2, and the surface resistivity of the nickel-tungsten-phosphorus plating is 0.15-0.23 omega/cm2. The short-process preparation methodcan be applied to the field of corrosion prevention.
