The invention discloses a high impact chlorinated polyvinyl chloride pipe material and a preparation method thereof. The high impact chlorinated polyvinyl chloride pipe material is prepared from the following raw materials in parts by weight: 40-60 parts of chlorinated polyvinyl chloride (CPVC) resin, 30-50 parts of polyvinyl chloride (PVC) resin, 0.3-0.6 part of polyethylene wax, 20-30 parts of active light calcium, 2-3 parts of dimethyl dimercaptoacetate isooctyl tin, 1-2 parts of barium stearate, 1-2 parts of ACR-401, 8-10 parts of HIPS, 2-3 parts of HIPS-g-PMMA, 4-7 parts of impact modifier ACM resin and 5-10 parts of a composite filler. Due to addition of a proper amount of HIPS, impact modifier ACM resin and other impact modifiers, the impact performance of the CPVC pipe material disclosed by the invention is greatly enhanced, such problems of the CPVC pipe material as water leakage, water seepage and breakage due to poor impact performance are solved effectively, and the service life of the pipe materi
