The invention discloses an oil-absorbing polyurethane foam material and a preparation method thereof, and the oil-absorbing polyurethane foam material is prepared by the following steps: reacting a pretreatment matrix, a modified monomer, octadecyl methacrylate and butyl acrylate, coating the surface of the pretreatment matrix with polyacrylate molecules, and soaking in an ethanol solution of zinc nitrate hexahydrate. Molecules of the pretreated matrix contain an organic silicon structure, a large number of benzene ring structures and long-chain fluoroalkyl structures, the molecules are of a latticed structure, the water absorption of the modified matrix is reduced, the oil absorption effect is improved, the surface of the modified matrix is coated with a polyacrylate structure, polyacrylate molecules contain long-chain alkyl and benzene ring structures, and the oil absorption effect is improved. The hydrophobic property of the polyurethane foam material can be further improved, meanwhile, the hydrophobic sta
