Abstract
The present invention relates to a soft super-high gravity composite material for acoustic insulation and noise elimination, which belongs to the technical field of high molecular materials. Each component of the prevent invention has respective weight percentage content of 5 to 30% of high molecular polymer, 10 to 90% of tungsten, 3 to 10% of plasticiser, 1 to 5% of stabilizing agent and 1 to 10% of coupling agent, wherein the grain size of the tungsten is 100 nanometer to 2 micron. Besides good sound insulation and mechanical properties, the present invention also has the characteristics of flame resistance, anti-chemical medium, corrosion prevention, no poison, application property, etc. The defects of massiness and not easy processing of conventional sound insulation materials are overcome by the soft characteristic of the soft super-high gravity composite material for acoustic insulation and noise elimination. Thus larger space is provided for the application of the soft super-high gravity composite material for acoustic insulation and noise elimination. The present invention is suitable to be used as a sound insulation material for city aerial conveyer transportation, aviation and harbors and can be used for the vibration isolation treatment of light wall board sandwiches of building industry. The soft super-high gravity composite material for acoustic insulation and noise elimination has the advantages of effective noise reduction and working and living environment improvement.
Description
Technical field
What the present invention relates to is a kind of matrix material, particularly can be used for the soft superelevation proportion matrix material of sound insulation and noise reducing, belongs to polymeric material field.
Background technology
About the development of soundproof material and the history of using existing decades, but all there are some shortcomings in normally used in the market soundproof material, as the product cost height, mostly be mechanically resistant material and be difficult for secondary processing and the difficult sound insulation processing that is applied to irregularly shaped object etc.Its range of application is therefore limited.As everyone knows, the oise insulation factor of material is observed mass law: TL=20lgm+20lgf-43dB, in the formula: the oise insulation factor under the TL-sound wave vertical incidence condition, dB; The area density of m-material, kg/m
2F-incident acoustic wave frequency, Hz.When the material mass area ratio doubles, then acoustic transmission loss increases 6dB.As seen the high specific gravity characteristic can make material have high areal density, under the very little situation of thickness, can have higher sound insulation property.According to " mass law ", traditional picture brick wall, cement wall or the big material of mass area ratios such as Plate Steel, stereotype, though defening effect is all relatively good, because more thick and heavy, but processing and application property are poor, and the sound insulation that is not applied to irregularly shaped object is handled.
By literature search, Japanese Patent JP56059857, name is called: SOUND-INSULATING COMPOSITION (sound insulation composite material) discloses a kind of technology of preparing of soft soundproof material.Inorganic metals such as this patent employing lead powder are raw material, make the soft material with certain sound insulation property.But plumbous harmful to environment, and defening effect is also not enough.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of soft superelevation proportion matrix material that is used for sound insulation and noise reducing is provided, make it effectively reduce noise, do not endanger environment.The present invention is achieved by the following technical solutions, each component of the present invention and weight percent content thereof are: high molecular polymer: 5%～30%, particle diameter is the tungsten powder of 100 nanometers～2 micron: 10%～90%, softening agent: 3%～10%, stablizer: 1%～5%, coupling agent: 1%～10%; By mixing after injection moulding, mold pressing or calendering and moulding.
Wherein high molecular polymer can be rubber, thermoplastics or both mixtures, wherein rubber can be butadiene-acrylonitrile rubber, neoprene latex, natural rubber, thermoplastics is the chain macromolecular structure, for example polyethylene, polystyrene, polypropylene, polyvinyl chloride, softening agent comprises one or more in the following softening agent: dibutyl phthalate, dioctyl phthalate (DOP), diethyl phthalate.Coupling agent adopts one or more in the titante coupling agent.
The present invention has substantive distinguishing features and marked improvement, the present invention is except that having good sound insulation and mechanical property, but also have characteristics such as fire-retardant, anti-chemical medium, protection against corrosion, nontoxic application property, soundproof material is thick and heavy and its softish characteristics have overcome in the past, the shortcoming that is difficult for processing, bigger space is provided for application of the present invention, is suitable for doing the soundproof material at city aerial conveyor traffic, aviation and harbour, and the sound insulation of building trade Light trabs interlayer is handled.Use this kind matrix material can reduce noise, improvement work and living environment effectively.
