| titleOfInvention | A kind of efficient acoustic material and preparation method thereof |
| abstract | The present invention relates to acoustic material arts, solve in the prior art that acoustic material soundproof effect is poor, low-and high-frequency sound insulation is not comprehensive, there is the problems such as pollution, easy to aging, provides a kind of efficient acoustic material and preparation method thereof.Efficient acoustic material includes puigging, and sound absorbing layer, bubble layer, the bubble layer is between puigging and sound absorbing layer.The puigging is made of sound insulation compound, and the sound insulation compound is by including that the raw material of following substances is prepared: thermoplastic resin, inorganic filler, foaming agent；The inorganic filler 15-80wt%；The foaming agent is 5-15wt%, remaining is thermoplastic resin.The filler of different-grain diameter corresponds to the sound wave of different-waveband or frequency in the present invention, therefore more comprehensive to the consumption of the sound of different frequency energy, and soundproof effect is good, is suitable for promoting and applying. |
