Silencing plastic pipe with high intensity

Abstract

The invention discloses a silencing plastic pipe with high intensity. The silencing plastic pipe comprises a super-high density polyethylene outer pipe, a polyvinyl chloride resin layer and a foamed polyethylene inner pipe, wherein the polyvinyl chloride resin layer is arranged between the super-high density polyethylene outer pipe and the foamed polyethylene inner pipe; the polyvinyl chloride resin layer is connected with the super-high density polyethylene outer pipe through ABS plastic connection pieces; a reinforcing rib is arranged in the super-high density polyethylene outer pipe; a silencing cavity is formed between the foamed polyethylene inner pipe and the polyvinyl chloride resin layer; and a nylon and glass fiber mixing plastic piece is arranged in the silencing cavity. According to the silencing plastic pipe with high intensity, due to super-high density polyethylene and the silencing cavity, silencing and noise reduction can be well realized; furthermore, the super-high density polyethylene is high in wear resistance; by the adding of the reinforcing rib, the silencing plastic pipe is high in intensity; meanwhile, foamed polyethylene and polyvinyl chloride resin also have the silencing and noise reduction functions; a honeycomb structure in the polyvinyl chloride resin can well absorb sound; and the silencing plastic pipe is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing high-strength plastic pipes, in particular to a sound-absorbing high-strength plastic pipe. Background technique [0002] Existing plastic pipes are developing rapidly in our country, and the country also strongly supports the development of plastic pipes. All provinces have formulated policies to promote the use of plastic pipes in new and rebuilt buildings, and eliminate high-energy-consuming products such as cast iron pipes. The plastic pipes used for building drainage are mainly PVC solid wall pipes, which have poor sound insulation effect and large drainage noise. With the improvement of people's living standards, the quality requirements for the environment and building materials are also getting higher and higher, energy saving, environmental protection and humanization It is a new requirement for chemical building materials. Users are paying more and more attention to the sound ins...

[0002] Existing plastic pipes are developing rapidly in our country, and the country also strongly supports the development of plastic pipes. All provinces have formulated policies to promote the use of plastic pipes in new and rebuilt buildings, and eliminate high-energy-consuming products such as cast iron pipes. The plastic pipes used for building drainage are mainly PVC solid wall pipes, which have poor sound insulation effect and large drainage noise. With the improvement of people's living standards, the quality requirements for the environment and building materials are also getting higher and higher, energy saving, environmental protection and humanization It is a new requirement for chemical building materials. Users are also paying more and more attention to the sound insulation and noise reduction requirements of drainage pipes. Moreover, the existing pipes are easy to break and the strength is not enough. Therefore, a plastic pipe with noise reduction and high strength is needed.
