Abstract
The invention discloses a noise-damping pipe. The noise-damping pipe is prepared from the following raw materials according to weight ratio: 90-110 of polypropylene, 2-6 of calcium sulfate and 0.2-1.8 of gray master batch. The formula of the noise-damping pipe mainly comprises polypropylene and calcium sulfate, as well as a proper amount of gray master batch. The noise-damping pipe has the advantages that: calcium sulfate with high density and a special molecular structure is used to absorb the energy of sound wave, thus the sound generated by rapid air compression caused by water flow in a drainage pipeline is reduced; and the special sound-absorbing material calcium sulfate is added to absorb audible sound wave, thereby greatly reducing noise.
Description
Technical field:
The present invention relates generally to a kind of hush pipe.
Background technology:
Vestolen PP 7052 hush pipe on the market is that Vestolen PP 7052 adds the PA tube that stopping composition is made, and the weight proportion of its each feed composition is a Vestolen PP 7052: 100; Stopping composition: 60; The grey look is female: 1. for reducing cost, how manufacturers only can go to study the ratio increase of stopping composition, cause the Vestolen PP 7052 hush pipe on all present markets not have erasure effect at all.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, a kind of hush pipe of good muffling effect to be provided.
The present invention realizes through following technical scheme:
A kind of hush pipe is characterized in that: the weight proportion of its each feed composition is:
Vestolen PP 7052 90-110
Permanent white 2-6 grey look female 0.2-1.8.
A kind of hush pipe is characterized in that: the weight proportion of its each feed composition is:
Vestolen PP 7052 100
Permanent white 4 grey looks female 1.
Permanent white, chemical name has another name called tiff.Be odorless, tasteless colourless rhombic system crystal or white unformed powder.Stable in properties is insoluble in water, acid, alkali or organic solvent.Its ability absorption frequency scope is 20～2 * 104 hertz a audible sound.
Advantage of the present invention is:
The main raw material of the present invention's prescription is Vestolen PP 7052 and permanent white, adds an amount of look mother.Absorb the energy of sound wave through highdensity special molecular structure material permanent white, cause the sound that the Fast Compression of air produces thereby reduce because of current in the drainage pipeline; Add singularity sound-absorbing material permanent white, absorb audible sound, thereby reduce noise greatly.
Embodiment:
A kind of hush pipe, the weight proportion of its each feed composition is:
Vestolen PP 7052 100
Permanent white 4 grey looks female 1.
Claims (2)
