The felt is used by forming a bulky felt such as a needle felt or a resin felt into a tubular shape. The foam material is formed by forming a homopolymer or a copolymer of urethane, styrene, urea, other thermoplastic resin or thermosetting resin as a raw material. In this case, the slab foam may be formed into a necessary tubular shape, or may be formed by injection molding.

The sound insulating layer 5 is formed into a sheet by a roll or the like. The thickness of the sound insulation layer 5 is 0.3
It is appropriate that the thickness is 5 mm or more and 5 mm or less. If the thickness is less than 0.3 mm, a sufficient sound insulating effect cannot be expected, and if the thickness exceeds 5 mm, the space between the inner tube 2 and the outer tube 3 must be large, which is uneconomical. It is.

m or less is appropriate. If the thickness is less than 1 mm, a sufficient sound absorbing effect cannot be expected, and if the thickness exceeds 10 mm,
This is because the space between the inner tube 2 and the outer tube 3 must be large, which is uneconomical.

As the rubber-based material, natural rubber, butadiene rubber, styrene-butadiene rubber, synthetic rubber such as isoprene rubber, or reclaimed rubber obtained by collecting and regenerating these rubbers is used. These rubbers can also be used by appropriately mixing.

The sound insulating layer 5 is formed into a sheet by a roll or the like. The thickness of the sound insulation layer 5 is 0.3
It is appropriate that the thickness is not less than 5 mm and not more than 5 mm. If the thickness is less than 0.3 mm, a sufficient sound insulation effect cannot be expected, and if the thickness exceeds 5 mm, the space between the inner tube 2 and the outer tube 3 must be large, which is uneconomical. It is.

音が行われる。In the present invention, the sound absorbing layer 6 is formed by the two layers of the sound absorbing layer 4 and the sound insulating layer 5.
When the sound-absorbing layer 6 is formed by the two layers of the sound-absorbing layer 4 and the sound-insulating layer 5, first, the sound energy is converted into heat energy by the sound-absorbing layer 4 covering the inner tube 2, and efficient sound absorption is performed. .

And if it is a soundproof pipe material for drainage of building equipment according to the present invention, when drainage flows through the inner pipe, the inner pipe is generally made of a lightweight resin material such as vinyl chloride resin, so that fine vibrations occur, and At the same time as the vibration, the flow noise of the liquid propagates to the periphery.

効果的に防音、遮音することができることとなる。The sound can be absorbed by first converting the sound energy into heat energy by the sound absorbing layer covering the inner tube. Next, sound can be further isolated by the sound insulation layer formed outside the sound absorption layer. Therefore, both the vibration sound and the liquid flow sound can be effectively sound-proofed and sound-insulated.

A sound insulation effect can be expected.
