Description
Technical field
The present invention relates to sound-absorbing material technology, more particularly to a kind of fibrous thermal sound-absorbing material and preparation method thereof.
Background technology
With industrial production, communications and transportation, urban architecture development, and the increase of the density of population, home amenity（Sound equipment, sky
Tune, television set etc.）Increase, ambient noise is increasingly serious, it become pollution human society environment a big public hazards.Noise is not
Hearing, but also the cardiovascular system to people, nervous system, internal system can be only affected to have a negative impact.
Sound insulation and noise reduction also becomes one and concerns people's living standard, the important topic of coordinated development.At present sound insulation and noise reduction is adopted
Sound-absorbing material is divided into by sound absorbing mechanism：
1. leaning on makes the porous material of SATT from a surface to many tiny unlimited ducts in inside, is to absorb medium-high frequency sound wave
It is main, have the various organic or inorganic fiber and its products of fibrous aggregate structure and the open cell foam of loose structure and
Expanded perlite product.
2. by the flexible material of resonant interaction sound absorption（Such as obturator-type foamed plastics, intermediate frequency is absorbed）, film material（Such as plastics
Film or cloth, canvas, varnished cloth and artificial leather, absorb Low Medium Frequency）, board-like material（Such as glued board, hardboard, cement asbestos board
And plasterboard, absorb low frequency）With perforated plate (on various board-like materials or metallic plate punch and be obtained, absorption intermediate frequency).
Above Material cladding is used, and can expand sound absorption scope, improves acoustic absorptivity.With decoration acoustic absorption is adherent or furred ceiling,
Porous material and perforated plate or film material combination are loaded on metope, or even are hung using cloud-drift-like sound, can all improve indoor tone quality, control
Noise processed.Porous material is in addition to absorption air sound, moreover it is possible to weaken solid sound and the vibration caused by empty room gas sound.By porous material
Insert in the composite construction of various board-like material compositions, sound-insulation capability can be improved and mitigate construction weight.
Current sound-absorbing material species is various but fastness is poor, causes erasure effect unstable；Part sound-absorbing material solidification
When release formaldehyde, cause environmental pollution；Long-time uses easy breed bacteria；Sound-absorbing material poor rigidity, the scope of application is little.
The content of the invention
It is an object of the present invention to be directed to above-mentioned problems, a kind of fibrous thermal sound-absorbing material, the material prescription section are proposed
