High toughness and high strength PVC drainage pipe material

Abstract

Belonging to the technical field of building pipelines, the invention relates to a high toughness and high strength PVC drainage pipe material. The PVC drainage pipe material includes the following components by mass: 100 parts of PVC-5 (polyvinyl chloride-5); 2-3 parts of a stabilizer; 10-14 parts of calcium stearate; 1-3 parts of rutile titanium dioxide; 2-6 parts of CPE; 0.1-1.3 parts of PE wax; and 0.1-3 parts of stearic acid. According to the invention, the compatibility is reasonable, and a high strength and high toughness drainage pipe can be prepared.

Description

technical field [0001] The invention belongs to the technical field of construction pipes, and relates to a PVC drainage pipe material with high toughness and high strength. Background technique [0002] Drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting and discharging sewage, waste water and rainwater. Including main pipes, branch pipes and pipelines leading to treatment plants, no matter they are built on streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipelines. With the rise of PVC pipes, it has replaced traditional pig iron pipes, galvanized pipes and some other metal pipes. [0003] PVC (full name Polyvinylchlorid) is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is...

Problems solved by technology

Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), the physical properties are poor (such as upper water pipes need to withstand a certain water pressure, soft PVC is not suitable for use), so its scope of use is limited

Therefore, rigid PVC pipes are generally used as pressure-resistant water supply and drainage pipes, but with the development of the construction industry, ordinary PVC pipes are no longer suitable for super high-rise buildings, which requires a PVC pipe suitable for super high-rise buildings. The strength of the pipe mainly depends on the material from which the pipe is made.
