Anti-corrosion polystyrene, preparation method thereof and positioning tool for preparation

The invention discloses anti-corrosion polystyrene, a preparation method thereof and a positioning tool for preparation, and belongs to the field of preparation of anti-corrosion polystyrene. The anti-corrosion polystyrene is prepared from a styrene monomer and rubber through a polymerization reaction. The positioning tool for preparing the anti-corrosion polystyrene comprises a bottom plate, a box body, a positioning column and a stirrer. The box body is slidably connected to the upper part of the bottom plate, so that polystyrene prepared in the box body is convenient to take out; the positioning column is mounted on the bottom plate, so that the box body is positioned, and interference between the box body and the stirrer 7 is avoided; two turning plates are arranged in the stirrer to apply shear stress to a mixture in the box body; and a connecting rod is arranged between the two turning plates, so that the angles of the two turning plates can be adjusted at the same time, and the polystyrene preparation
