The invention discloses a preparation method of anti-permeability waterproof materials. The preparation method comprises the steps of step one, preparing modified asphalt stab-resistance mixture including 40-50 parts of asphalt, 10-15 parts of regenerated butylbenzene rubber powders, 5-10 parts of base oil and other waterproof stab-resistance fillers; step two, spreading a base fabric, wetting the inner surface of a conveyer belt by water, and flatly spreading the base fabric on the conveyer belt; step three, folding edges: folding all the edges of the base fabric; step four, preparing a chemical stab-resistance and anti-permeability waterproof layer: heating the modified asphalt stab-resistance mixture, then coating the heated modified asphalt stab-resistance mixture on the base fabric uniformly by two times, and spreading a wire mesh layer in the inner part of the base fabric; step five, coating a film: coating a film layer on the chemical stab-resistance anti-permeability waterproof layer; and step six, co
