Abstract
The utility model discloses a kind of rubber combined layer of the sound insulation of downcomer, the rubber combined layer of the sound insulation from the inside to the outside, is followed successively by buffer layer, sound insulating layer, anti-water resistance wet layer, by self-adhesion gemel connection between every layer；Described buffer layer is porous flexible rubber plastic foam material, and described sound insulating layer is high density rubber sheet, and described anti-water resistance wet layer is compound aluminium foil material；The rubber combined layer of described sound insulation is coated on outside sewer pipe, is wrapped up between described sound insulation rubber combined layer and described sewer pipe by self-adhesion gemel connection.The utility model is directly coated on downcomer outer wall, and the buffer layer of innermost layer plays sound absorption cushioning effect, and high density rubber sheet plays sound insulation effect, and outermost compound aluminium foil material plays the wet effect of anti-water resistance, greatly extends the service life of downcomer.According to laboratory test results, under same external environment condition, the utility model can reduce downcomer noise 10-15 decibels.
Description
Technical field
A kind of sewer pipe technical field is the utility model is related to, especially a kind of rubber combined layer of the sound insulation of downcomer.
Background technology
Sewer sound insulation at present is generally using hollow internal spiral silencing pipeline or in common PVC pipeline outer cladding mineral wool
Deng perforate sound-absorbing material, but particularly evident noise reduction is had no in actual applications, and because open-cell material (such as mineral wool etc.)
Water imbibition, service life is short, easily mouldy in a humid environment.
Utility model content
The utility model discloses a kind of rubber combined layer of the sound insulation of downcomer, downcomer noise is reduced to indoor environment
Influence.
The technical solution of the utility model is as follows：
A kind of rubber combined layer of the sound insulation of downcomer, it is characterised in that it is described to insulate against sound rubber combined layer from the inside to the outside, successively
For buffer layer 2, sound insulating layer 3, anti-water resistance wet layer 4, by self-adhesion gemel connection between every layer；Described buffer layer 2 is porous flexible rubber
Expanded material is moulded, described sound insulating layer 3 is high density rubber sheet, and described anti-water resistance wet layer 4 is compound aluminium foil material；It is described
The rubber combined layer of sound insulation be coated on outside sewer pipe 1, it is described insulate against sound between rubber combined layer and described sewer pipe 1 by
Self-adhesion gemel connection is wrapped up.
The rubber combined layer of sound insulation is sheet material.
Described sewer pipe 1 is PVC pipeline or metallic conduit.
Effect of the present utility model is as follows：
The utility model is directly coated on downcomer outer wall using the elastomeric material of three-layer composite structure, innermost layer it is porous
Flexible rubber-plastic expanded material buffer layer plays certain sound absorption cushioning effect, and sound insulating layer is that high density rubber sheet plays sound insulation work
With, and outermost anti-water resistance wet layer plays the wet effect of anti-water resistance for compound aluminium foil material, greatly extends making for downcomer
Use the life-span.
According to laboratory test results, under same external environment condition, the utility model can reduce 10-15 points of downcomer noise
Shellfish.
Brief description of the drawings
Fig. 1 is that the utility model is coated on cross-sectional view after sewer pipe
Label in figure：
The anti-water resistance wet layers of 1- sewer pipe 2- buffer layer 3- acoustic pads 4-
Embodiment
Following examples are only to illustrate the utility model example to be clear, and not to reality of the present utility model
Apply the restriction of mode.For those of ordinary skill in the field, other can also be made on the basis of the following description
Various forms of changes or variation, and these belong to the obvious changes or variations that the utility model spirit is drawn and still located
Among the scope of protection of the utility model.
As shown in figure 1, be a kind of rubber combined layer of sound insulation of downcomer of the present utility model, the rubber combined layer of sound insulation
From the inside to the outside, buffer layer 2, sound insulating layer 3, anti-water resistance wet layer 4 are followed successively by, by self-adhesion gemel connection between every layer；Described buffer layer 2
For porous flexible rubber plastic foam material, described sound insulating layer 3 is high density rubber sheet, and described anti-water resistance wet layer 4 is compound
Aluminum foil material；The rubber combined layer of described sound insulation is coated on outside sewer pipe 1, the described rubber combined layer of sound insulation with it is described under
Wrapped up between waterpipe 1 by self-adhesion gemel connection.The rubber combined layer product of the utility model sound insulation can be fabricated to sheet material, for existing
Field cladding sewer pipe.Product can also be combined into sewer pipe, is directly used.
Described sewer pipe 1 is PVC pipeline or metallic conduit.
Above-mentioned porous flexible rubber plastic foam material, high density rubber sheet, compound aluminium foil material, self-adhesion glue material are city
Sell material.
