The invention discloses a formula of a composite spiral tube material. The formula comprises polyethylene, a filled reinforcing agent, a plasticizer, an impact-resisting modifying agent, a foaming agent and a coupling agent. The filled reinforcing agent is carbon fiber, the plasticizer is dimethyl phthalate, the impact-resisting modifying agent is ethylene propylene diene monomer, the foaming agent is diisopropyl azodicarboxylate, and the coupling agent is ethylenediamine propyl triethoxy ethyl silane. Multiple types of additives are added into polyvinyl plastic to enable prepared composite spiral tube material to have the advantages of being hard in texture, good in toughness, high in tensile strength, light in weight, low in cost and the like, thereby greatly improving the performance of composite spiral tubes, decreasing weight of the composite spiral tubes and facilitating construction requirements.
