Abstract
The invention provides a preparation method of a powder metal composite sound insulation coiled material. The powder metal composite sound insulation coiled material comprises macromolecule elastomer polymer and metal powder. The particle diameter of the metal powder is smaller than 1mm. The macromolecule elastomer polymer comprises rubber, plastic, polyurethane, asphalt and the like. Due to the fact that a plurality of gaps exist in the stereo meshwork structure of the macromolecule elastomer polymer, the metal powder is mixed and then added into the macromolecule elastomer polymer, and then the powder metal composite coiled material is formed by pressing. The requirement of the sound insulation field of current building walls is met.
Description
Technical field
The present invention is the preparation method of a kind of powdered-metal composite sheet material being suitable for Sound insulation for building field.
Background technology
At present, country advocates the energy saving building that saves land energetically, and various buildings are more and more higher, supports load for alleviating structure,
Country carries out aerated bricks energetically, disables solid brick, and such building concentration wall is increasingly lighter, so can bring an acoustic problems:
The sound insulation property of body of wall worse and worse, does not reaches relevant Sound insulation for building standard-required, because sound insulation of wall performance observes " mass law ",
I.e. sound insulation of wall performance is directly proportional to the quality of body of wall unit are.The most common way is to do a cavity in body of wall side,
The inside is full of the sound-absorbing way that glass cotton is closed again with dalle, and the effect of do so is less desirable, accounts for the most very much volume, city
It is badly in need of solving the sound insulation problem of this light weight wall on field.
Summary of the invention
The present invention, according to architectural acoustics sound insulation " mass law " principle, installs a floor height proportion additional in Light Wall side
Material, the proportion of common metal material is bigger, belongs to high specific gravity material.But in the market metal material all with tabular,
Block, bar form uses in a large number.In body of wall side weld plate material not only heaviness but also very bad construction, the shortcoming such as the most easily get rusty.
The present invention is that hyperbaric metal material is made metal dust, and trickle metal dust is joined macromolecular elastomer polymer
In, because being formed space network by various macromolecules in macromolecular elastomer polymer, its structure has a large amount of space, so
Just can be added thereto to a large amount of fine metal powder.The macromolecular elastomer polymer being mixed with a large amount of metal dust can be pressed into respectively
Plant the coiled material of softness, sheet material, sheet material etc., be convenient for people to cut use easily in different field, to solve current building wall
The sound insulation problem of body.
For realizing the purpose of the present invention, one aspect of the present invention provides a kind of powdered-metal compound sound insulation sound coiled material, including high score
Bullet elastomer polymer and metal dust, it is characterised in that the particle diameter of described metal dust is less than 1.0mm, and the smaller the better.
Wherein, macromolecular elastomer polymer includes rubber, plastic cement, polyurethane, Colophonium etc. polymer.
Another aspect of the present invention provides a kind of powdered-metal to be combined the preparation method of sound insulation coiled material, carries out including order below
Step:
1. add hot mixing
Macromolecular elastomer is heated to molten condition, appropriate metal dust is added thereto and stirs.
The most compressing
Become to set the coiled material of thickness by the elastomer that mixes with metal extrusion press, cover above layer of plastic film or
Upper work cloth, in case being mutually bonded, so that it may is rolled into coiled material packing stand-by.
Accompanying drawing explanation
Fig. 1 is the generalized section that powdered-metal of the present invention is combined sound insulation coiled material.
Description of reference numerals: 1. macromolecular elastomer polymer.2. metal dust.
Detailed description of the invention
Embodiment, in Sound insulation for building field, by containing the contour resilient flexible material made than heavy metal powder of iron and steel, makes difference
Thickness coiled material, can play good sound insulation effect, and its soft flexible available cutter cuts, very convenient to use.
In sum, the application of powdered-metal composite sound-insulation material will have quite varied prospect.
Claims (5)
1. it is applicable to a preparation method for the powdered-metal composite sheet material in Sound insulation for building field, including macromolecular elastomer polymer and gold
Belonging to powder, its feature is to join in macromolecular elastomer polymer metal dust, thus make rich in metal dust soft
Soft metal composite sheet material.
2. according to described in right 1: macromolecular elastomer polymer can be rubber, plastic cement, polyurethane, Colophonium etc..
3., according to described in right 1: the particle diameter of metal dust is less than 1mm, and usual metal dust diameter is the least, add effect more
Good, make the tenor in coiled material the highest.
Metal dust the most according to claim 3, it is desirable to select proportion (＞ 6 gram per centimeter3) metal dust.
5. according to the metal dust described in right 3, it is also possible to be enriched in metal mining powder.
