The invention relates to a PVC (polyvinyl chloride) silencing water drainage pipe and a production method thereof. The PVC silencing water drainage pipe is prepared from being prepared from the following raw materials in parts by weight: 80 to 100 parts of polyvinyl chloride resin, 100 to 130 parts of nano anhydrous calcium sulfate, 5 to 8 parts of a stabilizer, 2 to 5 parts of a modifier, 0.5 to2.0 parts of PE (polyethylene) wax, 0.5 to 2 parts of an aluminate coupling agent and 0.2 to 0.5 part of a compound antioxidant. The raw materials of the PVC silencing water drainage pipe are simple and easy to obtain, so that the PVC silencing water drainage pipe is low in cost, extremely high in aging resistance, flexibility, low-temperature resistance and high-temperature resistance; by the adding of a methyl methacrylate-butadiene-styrene copolymer, the PVC silencing water drainage pipe achieves a silencing effect; the low-temperature toughness and the impact resistance are improved; the PVC silencing water drainage pipe has a shock absorption function.
