The invention discloses a three-layer noise reduction drainage pipe, which comprises a drainage pipe body, wherein the drainage pipe body is a three-layer co-extrusion composite pipe formed by an impact-resistance outer layer, a noise reduction middle layer and an impact-resistance inner layer through co-extrusion. The noise reduction middle layer is a sound-absorbing middle layer or a sound insulation middle layer made of expandable polyvinyl chloride composition materials. The above layers are prepared with the following materials. The impact-resistance outer layer is made of polyvinyl chloride resin, chlorinated polyethylene, dibasic lead phosphite, tribasic lead sulfate, calcium stearate, lead stearate, paraffin, PVC processing and modifying agent, active light calcium carbonate, titanium dioxide and dioctyl phthalate. The sound-absorbing middle layer is made of polyvinyl chloride resin, chlorinated polyethylene, lead salt stabilizer, calcium stearate, stearic acid, paraffin, dioctyl phthalate, active light calcium carbonate and barium sulfate. The sound insulation middle layer is made of polyvinyl chloride resin, methacrylic ester polymer and inorganic foaming agent. Compared with the outer layer, the impact-resistance inner layer comprises the same components with the outer layer, except that PVC is adopted instead of polyvinyl chloride resin. The noise of the drainage pipe can be effectively reduced and the intensity of the drainage pipe is enhanced.
