Abstract
The present invention relates to a sound isolation noise reduction material which belongs to the technical field of high molecular materials. The present invention is composed of components of the following proportion by weight: 5 to 45% of PVC, 30 to 90% of inorganic powder, 1 to 10% of coupling agent and 4 to 15% of auxiliary agent, wherein the inorganic powder is high gravity metal powder, inorganic salt powder or the mixture of the high gravity metal powder and the inorganic salt powder, wherein the metal powder is tungsten or/and bismuth or/and copper or/and cobalt or/and molybdenum or/and aurum or/and argentum or/and nickel, and the inorganic salt powder is heavy barium carbonate or/and barite or/and barium sulfate. Besides the advantages of flexibility and sound insulation performance, the present invention also has the characteristics of flame resistance, chemical medium prevention, corrosion prevention, non poison, application perfoemance, etc., and is suitable for places and environment having strict phonic requirements. Taking materials which are made by using copper powder as raw materials for example, a sound insulation index can be 21.2 db (100 to 1600Hz) by the thickness of 1mm.
Description
Technical field
What the present invention relates to is the material of a kind of compound substance, particularly a kind of sound insulation and noise reducing, belongs to polymeric material field.
Background technology
About the development of sound insulating material and the history of using existing decades, the development and the production system of comparative maturity have been formed, but normally used in the market sound insulating material all exists some shortcomings such as cost of products height, mostly be hard material, be difficult for secondary processing and the irregularly shaped object processing of insulating against sound.Therefore its range of application has certain limitation.Find by literature search, Japanese Patent No. is: JP56059857, name is called: SOUND-INSULATING COMPOSITION (sound insulation composite material), this patent has been announced a kind of preparation of sound insulating material, inorganic metals such as employing lead powder are raw material, make the soft material with certain sound insulation property.But because plumbous harmful to environment, defening effect neither be very good simultaneously.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of material of sound insulation and noise reducing is provided, make its more effective reduction noise, and improvement work and living environment.The present invention is achieved by the following technical solutions, each component of material of the present invention and weight percent content thereof are: PVC:5%~45%, inorganic powder: 30%~90%, inorganic powder is high specific gravity metal powder, inorganic salts powder or both potpourris, metal powder is one or more of tungsten, bismuth, copper, cobalt, molybdenum, gold, silver, nickel, the inorganic salts powder be the heavy barium carbonate or/and barite or/and barium sulphate, coupling agent: 1%~10%, auxiliary agent: 4%~15%; By mixing after injection moulding, mold pressing or calendering and moulding.
Coupling agent adopts one or more in the titante coupling agent, one or more in the common stabilizing agent of selection of auxiliary, plastifier and the antiaging agent.
The present invention has substantive distinguishing features and marked improvement, material of the present invention is except that having the good and sound insulation property height of flexibility, but also have characteristics such as fire-retardant, anti-chemical medium, anticorrosion, nontoxic application property be good, the material that with the copper powder is feedstock production is an example, and the sound reduction index of 1mm thickness can reach 21.2 decibel (100~1600Hz).The present invention is suitable for doing the sound insulating material at city aerial conveyor traffic, aviation and harbour, and the vibration isolation of building trade Light trabs interlayer processing, uses this kind sound insulation composite material can reduce noise, improvement work and living environment effectively.
