The invention discloses a preparation method of an anti-radiation diatom plate, and relates to the technical field of building materials. When the anti-radiation diatom plate is prepared, firstly, ferric chloride, ferrous chloride and ammonia water react to prepare composite particles, polyethylene glycol sequentially reacts with succinic anhydride, thionyl chloride and 3-aminopropyltrimethoxysilane to prepare modified polyethylene glycol, the composite particles and the modified polyethylene glycol react to prepare modified composite particles, and the modified composite particles and the modified polyethylene glycol react to prepare the anti-radiation diatom plate. The preparation method comprises the following steps: reacting ethyl diallyl silane, adding triethoxysilane, reacting to obtain hyperbranched organic silicon, and reacting the hyperbranched organic silicon with diatomite to obtain modified diatomite; and mixing the modified composite particles, diatomite, modified diatomite, active alumina micro powder, active silica micro powder and pure calcium aluminate cement, curing in a mold, standing at multiple temperature sections, carrying out vacuum impregnation treatment by using paraffin, polishing, and coating the surface with tetraethoxysilane to obtain the anti-radiation diatom plate. The prepared anti-radiation diatom plate has excellent fracture toughness and wear resistance.
