Abstract
The utility model discloses a polyvinyl chloride mute drain pipe, which comprises an inner layer, a sound-absorbing core layer and an outer layer, wherein the sound-absorbing core layer is of the honeycomb structure. The polyvinyl chloride mute drain pipe has the advantages of obvious noise-reduction effect, better impact-resistance strength and tensile strength and convenient easy installation and use.
Description
Technical field
The utility model relates to a kind of waste pipe, especially a kind of polychloroethylene mute waste pipe that can significantly reduce draining noise.
Background technique
PVC (UPVC) waste pipe is with its cheapness, attractive in appearance, installation and maintenance convenience, and grow and extensively adopt in the whole world working life.But noise was very big when it had a fatal weakness to be draining, influenced the room peace and quiet, sometimes people was waken up with a start from the dreamland of sweetness.Face of noise, people have done many effort, various noise reduction waste pipes have been developed in succession, as: Japanese publication, Te Kaiping 5-271429, the model utility name is called and discloses a kind of technology that can make common supplying drainage reduce noise in " sound insulation tubing ", this sound insulation tubing is mainly by vinyl chloride resin, plasticizing agent, barium sulphate compositions such as (BaSO4), though it also contains barium sulphate (BaSO4), but it is to extrude the medium-soft tubing that is processed into barium sulfate-containing (BaSO4) earlier, in the time of installation this medium-soft tubing is broken the outside that is wrapped in the normal discharge pipe, so poor practicability, profile is not attractive in appearance, also inconvenience is installed, is difficult to realize industrialization.
Summary of the invention
The purpose of this utility model provide a kind of can significantly reduce draining noise the polychloroethylene mute waste pipe.
The technical solution of the utility model is: the polychloroethylene mute waste pipe, comprise internal layer, sound-absorbing sandwich layer, skin, and described sound-absorbing sandwich layer is a cellular structure.
Described internal layer internal surface has spiral bar.
The most significant advantage of the utility model is: with respect to common polyvinyl-chloride drainage pipe noise reduction 2.7～12.3dB, and still have impact strength and tensile strength preferably, and easy to install.
