Abstract
The present invention relates to a high specific weight sound installation composite 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 35% of PVC, 40 to 90% of tungsten, 1 to 10% of coupling agent and 4 to 15% of auxiliary agent, wherein the grain size of the tungsten is 2 to 60 microns. Besides the advantages of softness and good sound insulation performance, the high specific weight sound installation composite material also has the characteristics of flame resistance, anti-chemical medium, corrosion prevention, no poison, application property, etc., and is suitable for sound insulation materials for city aerial conveyer transportation, aviation and harbors. The high specific weight sound installation composite material can also be used for the sound insulation treatment of light wall board sandwiches of building industry. Noise can be effectively reduced and working and living environment can be improved by using the high specific weight sound installation composite material. When the thickness of the high specific weight sound installation composite material is 1mm, the sound insulation quantity of sound of 100-1600Hz can reach 20 to 25 dB.
Description
Technical field
What the present invention relates to is a kind of matrix material, and particularly a kind of hyperbaric sound insulation composite material belongs to polymeric material field.
Background technology
About the development of soundproof 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 soundproof material all exists some shortcomings such as product cost height, mostly be mechanically resistant material, therefore be difficult for secondary processing and handle with the sound insulation that is difficult to use in irregularly shaped object.It uses therefore limited.Find by literature search, China Patent No. is: 97197487.X, patent name is: high density composite, announced a kind of high density composite, this patent the tungsten powder combination of 2~40 microns of the fiber that improves intensity and diameters, is made a kind of material (as projectile core equivalent material nontoxic, unleaded, environmentally safe, that save money) that can be used as plumbous substitute by binding agent.Its material composition is tungsten powder and fiber and caking agent, by injection moulding, compression molding, is used to be sought after the occasion that plumbous high-density does not wish to have Lead contamination again, can be used as the substitute of leaded high density material.But this material since its composition (fiber and caking agent) only determined can be with injection moulding or compression molding, so difficulty is made large-area film.
Summary of the invention
The objective of the invention is to overcome the deficiency in the background technology, a kind of hyperbaric sound insulation composite material is provided, make it have softness, easy secondary processing, the property used is strong, applicable to the advantages such as sound insulation processing of irregularly shaped object.The present invention is achieved by the following technical solutions, and each component of the present invention and weight percent content thereof are: PVC:5%~35%, particle diameter are 2~60 microns tungsten powder: 40%~90%, and 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 stablizer of selection of auxiliary, softening agent and the antiaging agent.
The present invention has substantive distinguishing features and marked improvement.The present invention is except that the softness with material the good and sound insulation property height, but also have characteristics such as fire-retardant, anti-chemical medium, protection against corrosion, nontoxic application property be good, fiber and caking agent particularly in material composition, have been abandoned, therefore can make large-area flexible film by rolling continuously shaped technology, be 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 sound insulation composite material can reduce noise effectively, improvement work and living environment when material thickness is 1mm, can reach 20~25 decibels to the mean transmission loss of 100~1600Hz sound.
