Abstract

The invention relates to a nano foam sound-absorbing material, using foam material as carrier, mixing nano calcium carbonate, common calcium carbonate with additive and water, blending and milling into slurry, then coating the slurry on to the foam material to naturally solidify and make them compound an organic whole. Compared with foam ceramic sound-absorbing material and net compound sound-absorbing material, it has the following advantages: (1), greater specific surface area, average noise reduction rate up to above 0.9 and increasing by 30%; (2), higher mechanical performance, pressive strength up to -5MPa at normal temperature and increasing once; better weatherability; (4) better heat resistance and fire retardancy.

Description

A kind of nanometer foam sound-absorbing material
Technical field
The present invention relates to a kind of sound-absorbing material, particularly a kind of nanometer foam sound-absorbing material.
Background technology
Traditional sound-absorbing material has flexible fiber shape sound-absorbing material and plaster particulate state sound-absorbing material at present, flexible fiber shape sound-absorbing material has good acoustical behavior, but material mechanical performance is poor, to such an extent as to can not directly exposing, it applies to outdoor sqouynd absorption lowering noise environment-friendly engineering, plaster particulate state sound-absorbing material comparatively robust is durable, but its acoustical behavior is poor.
Foamed ceramics sound-absorbing material and netted composite sound-absorbing material are two kinds of novel sound-absorbing materials inventing in recent years, and its mechanical property is better than flexible fiber shape sound-absorbing material, but fail to reach the good sound absorbing capabilities level of flexible fiber shape sound-absorbing material.
Summary of the invention
The objective of the invention is provides a kind of nanometer foam sound-absorbing material in order to overcome the problems referred to above and the deficiency that prior art exists.This nanometer foam sound-absorbing material has reached the effect of flexible fiber shape sound-absorbing material fully aspect acoustical behavior, have the firm mechanical property of material of construction simultaneously again.Nanometer foam sound-absorbing material goods can directly expose and apply to the noise reduction acoustic barrier that the rail traffic is rolled in motorway, viaduct, railway and city, the noise reduction furred ceiling in subway station, subterranean commercial area and tunnel, the acoustic panel in gymnasium, exhibition center, natatorium, music hall, theater, conference centre and voice classroom.
A kind of nanometer foam sound-absorbing material, it is to be carrier with the foam materials, and nano-calcium carbonate, normal silicate are mixed with additive and water, stir, grind and become slurry, be coated on the foam materials again, through air-set, make it to be combined into one, the content of its component (weight percent) is:
Major ingredient: lapis amiridis 20-30%
Silica powder 40-50%
Cement 20-30%
Auxiliary material: nano-calcium carbonate accounts for the weight ratio 1-3% of major ingredient
Rectorite leng accounts for the weight ratio 2-4% of major ingredient
Wilkinite accounts for the weight ratio 2-5% of major ingredient
Carboxymethyl cellulose accounts for the weight ratio 1-2% of major ingredient
Water: the weight ratio 20-25% that accounts for major ingredient
The lapis amiridis major ingredient is Al 2O 3
Composite sound-absorbing material is compared, and has the following advantages: (1) has bigger specific surface area, and average noise reduction reaches more than 0.9, has improved 30%; (2) have higher mechanical property, normal temperature ultimate compression strength reaches-5Mpa, is doubled; (3) have better weather resistance, can stand all the year round to expose to the weather and drench with rain, can not influence sound absorbing capabilities; (4) better heat-resisting and flame retardant property is arranged.
