Foam sound absorption material produced by using ceramic waste and production method of foam sound absorption material

Abstract

The invention discloses a foam sound absorption material and a production method of the foam sound absorption material. A ceramic waste serves as a main raw material in production. The foam sound absorption material comprises, by weight, 55-85 parts of the ceramic waste, 15-30 parts of superfine kaoline, 0.2-0.6 part of a suspending agent and 0-6 parts of zirconium oxide. An organic precursor-dipping high-temperature sintering process is used for producing the foam sound absorption material, the disadvantages that a convention sound absorption material is low in noise reduction coefficient, short is service life and easy to deliquesce and produce secondary pollution are overcome, the material is light in weight, acid-resisting, alkali-resisting, fire-proof and high temperature-resisting and can be used in noise-elimination noise barriers in urban streets, railways, subways, construction sites, central air-conditioner rooms and the like, and also can be used in public places such as hospitals, libraries, convention centers, exhibition halls, lecture halls, music halls, movie theaters, gymnasiums, commercial buildings, public houses, hotels and office buildings. The waste serves as the production raw material, the production cost is reduced, the dumped amount of the ceramic waste is reduced at the same time, environmental pollution is controlled, and the resourcization recycling utilization of the waste is achieved.

Description

technical field [0001] The invention relates to a sound-absorbing material and a manufacturing method of the sound-absorbing material. The product prepared by this method can be made into a certain size, and can be used in noise-absorbing and sound-proof barriers on highways, railways, construction sites, etc., and can also be used in hospitals, libraries, convention centers, lecture halls, concert halls, theaters, etc. And fitness, gymnasium, commercial building, hotel, office building and other public welfare places. Background technique [0002] Sound-absorbing material is a new type of material widely used in public welfare places such as hospitals, libraries, convention centers, music lecture halls, theaters, fitness centers, gymnasiums, hotels, and office buildings. It has a wide range of types and uses, and is forming a large-scale high-tech industrial group with a very broad market prospect. Sound-absorbing materials are the core of the field of new materials, and ...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides a foam sound-absorbing material produced by using ceramic waste and a preparation method thereof. The existing foam sound-absorbing materials have high production cost, low noise reduction coefficient, poor sound absorption effect, and insufficient compressive and flexural strength. , the service life is short, and the material is easy to deliquescence, easy to cause secondary pollution and other problems, and solve the problems of ceramic waste reuse and environmental pollution
