The invention provides a preparation method of a waterproof coating suitable for repairing ancient buildings, and relates to the technical field of building waterproof materials. Comprising the steps of preparing a modified fiber layer, adhering and preparing a waterproof material. The preparation method comprises the following steps: carrying out thin-passing on natural fibers and butylbenzene fibers on an open mill, uniformly coating rollers, plastifying, adding a premixed and crushed mixture of white carbon black and 2, 4-pyrazolone, which accounts for 3.8-4.5% of the total weight of the fibers, packing triangularly, uniformly mixing, and batching off; sequentially adding the active iron oxide, the sodium stearate, the anti-aging agent, the guanazole and the methyl oleate, adjusting the roller spacing to be small, carrying out thin-passing on a rubber material, then carrying out triangular package, adjusting the roller spacing to be large, and discharging a sheet; after the rubber material is stopped, remi
