The invention discloses a fireproof door core, which comprises the following raw materials by weight part: 45-50 of magnesium chloride, 5-8 of sodium chloride, 25-30 of magnesium oxide, 1-3 of nano-magnesium hydroxide, 25-35 of vermiculite power, 10-13 of perlite powder, 1-2 of gamma-methacryloxypropyltrimethoxysilane, 0.3-0.5 of stearic acid, 1-2 of sodium polyacrylate, 1-2 of decabromodiphenyl ethane, 1-2 of antimony trioxide, 2-4 of a silane coupling agent KH530, 25-40 of a special glue, 0.6-0.7 of polypropylene fiber, and a proper amount of water. According to the invention, the vermiculite power and perlite powder are firstly subjected to PH adjustment, then modification is carried out, so that a lot of cations therein are better replaced by cations, the compatibility is increased, the dispersion state is changed to be more uniform, and the disadvantage that adding of inorganic powder into the fireproof door core can cause negative effect on fireproof door core bending properties can be improved.
