Problems solved by technology

The biggest defect of plastic drainage pipes is the high noise, especially for high-rise buildings, which seriously affects the normal life and rest of residents
In order to solve the problem of noise nuisance, people in the industry have thought of many ways: for example, they have successively developed core layer foam tubes and inner wall spiral tubes. But it is far from the level of cast iron pipes, and the cost and strength are far less than solid wall plastic pipes

Abstract

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.

Description

technical field [0001] The invention belongs to the processing field of PVC drainage pipes, in particular to a PVC sound-absorbing drainage pipe and a production method thereof. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. Chemical building materials have made great progress and developed rapidly in our country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban constructio...
