Abstract

The invention belongs to the technical field of a novel building material and provides a ceramic sound-absorption material and a preparation method. The ceramic sound-absorption material comprises the following components in parts by weight: 25-29 parts of corundum, 7-14 parts of silicon carbide, 11-18 parts of quartzite, 6-12 parts of killas, 6-10 parts of sillimanite, 15-22 parts of processed talcum powder, 3-12 parts of attapulgite, 0.1-1.4 parts of ethylene-vinyl acetate, 0.5-1.5 parts of kapok fiber and 0.1-0.4 part of auxiliaries. The ceramic sound-absorption material is obtained by sintering according to the invention, is high in sound absorption strength, fire-proof, damp-proof, anti-freezing, anti-ageing, capable of resisting against chemical corrosion, light and thin, is free from any organic volatile matters and is a green environment-friendly sound-absorbing sound insulating material.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and in particular relates to a ceramic sound-absorbing material and a preparation method thereof. Background technique [0002] With the rapid development of society, noise pollution is becoming more and more serious. Sound-absorbing material is a functional material for building decoration. It has the dual requirements of sound absorption and decoration. It must be beautiful and meet the special requirements of sound absorption. Any material can absorb sound, but the degree of absorption varies widely. It is usually a material with an average sound absorption coefficient greater than 0.2, which is listed as a sound-absorbing material. [0003] The commonly used sound-absorbing and sound-insulating materials currently on the market usually have poor performances such as fire resistance, weather resistance, strength, sound absorption and sound insulation, and various problems are ...
