Abstract
The present invention relates to a kind of acoustical panel, making step are as follows:(1) sound absorbing layer is configured, 20 30 parts of tungsten powder, 40 50 parts of polyurethane, 10 15 parts of carbon black, 58 parts of naphthenic oil, 36 parts of stearic acid, 2 15 parts of zinc oxide are mixed, mixing time is 20 40min, temperature is 50 90 degree during stirring, normal temperature is naturally cooled to after the completion of stirring, obtains sound-absorbing layer material；（2）Sound-absorbing layer material is freezed, 20 degree of cryogenic temperature, cryogenic temperature is 1 3H, and nature is taken out after freezing and is dried in the air to normal temperature, attractive material is applied into sheet material top layer, and smearing thickness is 1 2cm, then drying.Improved formulations of the present invention, preparation method is simple, using special process, has very strong sound-absorbing effect, can accomplish good sound-absorbing original paper.
Description
Technical field
The present invention is more particularly directed to a kind of acoustical panel.
Background technology
At present, in the market has many composites, but density of material is small, the work either played to sound insulation, noise reduction etc.
With little, because the using effect of material, toughness, resistance etc. each depend on the density of material in itself, if material itself is close
Bottom is spent, then the effect of manufactured composite is more undesirable.
The content of the invention
The present invention proposes a kind of acoustical panel regarding to the issue above.
Specific technical scheme is as follows：
A kind of acoustical panel, it is characterised in that making step is as follows:
(1) sound absorbing layer is configured, by tungsten powder 20-30 parts, polyurethane 40-50 parts, carbon black 10-15 parts, naphthenic oil 5-8 parts, stearic acid
3-6 parts, zinc oxide 2-15 parts are mixed, mixing time 20-40min, and temperature is 50-90 degree during stirring, has been stirred
Normal temperature is naturally cooled to after, obtains sound-absorbing layer material；
（2）Sound-absorbing layer material is freezed, cryogenic temperature -20 is spent, cryogenic temperature 1-3H, and nature is taken out after freezing and is dried in the air to normal
Temperature, attractive material is applied to sheet material top layer, smearing thickness 1-2cm, then drying.
A kind of acoustical panel, it is characterised in that the zinc oxide is Zinc oxide powder.
A kind of acoustical panel, it is characterised in that the carbon black is carbon black pellet.
Beneficial effects of the present invention are：
Improved formulations of the present invention, preparation method is simple, using special process, has very strong sound-absorbing effect, can accomplish very well
Sound-absorbing original paper.
