The invention relates to a corrosion-resistant fireproof door core. A preparation method of the corrosion-resistant fireproof door core comprises mixing 30-40 parts of polyvinyl alcohol and 100-140 parts of water to obtain glue, putting the glue into a high speed shearing machine, adding 5-10 parts of expanded perlite, 3-6 parts of aluminum-magnesium silicate, 3-5 parts of aluminum oxide, 5-10 parts of modified nanometer titanium dioxide, 5-10 parts of nanometer zinc oxide, 70-95 parts of sulphate aluminium cement and 2-3 parts of an alkamine corrosion inhibitor into the high speed shearing machine, carrying out high speed shearing stirring at a shearing rate of 6000-8000RPM for 5-10min, transferring the mixture into a high speed mixer, adding 0.5-2 parts of a high-alumina cement foaming agent into the high speed mixer, carrying out stirring at a rotation rate of 1000-1500r/min for 10-15min, adding 20-30 parts of PVA short filaments into the high speed mixer, carrying out stirring at a rotation rate of 800-1000r/min for 5-10min, discharging the mixture into a mold, wherein the mold is filled with 10dm<3> steel wire cages stacked uprightly and foursquare, carrying out standing curing molding in the mold, taking out the product and carrying out drying until water content is 12%.
