The invention discloses an L-band wave-absorbing oil-resistant rubber sheet and a preparation method thereof. The hydrogenated butadiene-acrylonitrile rubber is used as a matrix, the flaky carbonyl iron, the nickel-plated carbon fibers and the nickel-plated carbon nanotubes are used as composite wave-absorbing fillers, and meanwhile, a processing aid, a cross-linking system and an aging antioxidant system are preferably selected, so that a low-frequency wave-absorbing and oil-resistant rubber product is obtained. The hydrogenated butadiene-acrylonitrile rubber is introduced as a rubber matrix, and has the advantages of oil resistance, chemical medium resistance, excellent adhesive property, excellent physical and mechanical properties and better low-frequency wave-absorbing property. According to the invention, the magnetic material flaky carbonyl iron is compounded with the dielectric materials nickel-plated carbon fibers and nickel-plated carbon nanotubes, and through the synergistic effect of the iron-base
