The invention provides a preparation method of a corrosion-resisting glass fiber material. The preparation method comprises the following steps: a, mixing glass fiber mineral powder, a vinyl cyanide monomer, nano zirconium oxide particles, graphene, sodium tripolyphosphate and ethyltrimethoxysilane in a stirrer and stirring at a high speed; then carrying out wiredrawing to obtain a material I; b, putting PS (Polystyrene) resin and sodium pyrophosphate into the stirrer and stirring and heating; then adding a hydrochloric acid solution and reacting to obtain a material II; c, mixing the material I and the material II in a smelting machine and smelting; stirring to obtain a material III; d, putting the material III into a drying oven and drying; then rapidly condensing to room temperature by utilizing a condensing machine; then putting the material III into an organic solvent and immersing; after drying again, thus obtaining the corrosion-resisting glass fiber material. The corrosion-resisting glass fiber material provided by the invention has a very good acid and alkali resisting property; meanwhile, the corrosion-resisting glass fiber material also has the advantages of good rigidity, ageing resistance and oxidization resistance.
