The invention discloses a PVC channel board for displaying auto spare parts, and good in toughness and strong in bearing capability. The PVC channel board comprises the following raw materials in parts by weight: 20-40 parts of polyvinyl chloride, 10-20 parts of polytetrafluoroethylene, 0.5-1.5 parts of butyl benzyl phthalate, 1-2 parts of polyphenylene sulfide, 1-2 parts of acrylic resin, 1-2 parts of magnesium stearate, 0.5-1.2 parts of foaming agent, 0.5-1.5 parts of stabilizing agent, 5-15 parts of modified potato starch, 10-20 parts of sepiolite powder, 5-12 parts of cyclodextrin, 0.2-1.5 parts of maleic anhydride, 0.5-1.2 parts of gamma-(ethylenediamine) propyl methyl dimethoxy silane, 0.5-1.2 parts of tetraisopropyl di(dilauryl phosphite) titanate, 1-2 parts of 2, 5-dimethyl-2, 5-di-tert-butyl peroxide hexane, and 1-2 parts of 2, 4-DCBP. The PVC channel board is excellent in abrasion resistance, good in high temperature resistance, excellent in stability, good in toughness and strong in bearing force. Meanwhile, the brittle fracture of the PVC channel board can be avoided.
