초록

본 연구는 실리카 에어로겔-펄프 복합체의 특성을 조사하였다. Paste 형태의 실리카 에어로겔과 펄프를 혼합하여 복합체를 제조하였으며, SEM 분석을 실시하였다. 또한 임피던스 튜브를 사용하여 흡음률을 측정하였다. 흡음계수의 피크치는 900 Hz 범위에서 얻어졌다. 실리카 에어로겔-펄프 혼합체는 우수한 흡음성능과 복합체의 표면이 소수성을 띠기 때문에 기인하는 내구성 때문에 새로운 흡음제의 가능성이 있다고 사료된다.

The studies on the characteristics of composite of silica aerogel and pulps were carried out. The composite was manufactured by mixing the paste of silica aerogel and pulps and analyzed by SEM. Using the impedence tube, the sound absorption measurement was investigated. The maximum value of sound absorption coefficient of this composite was obtained in the range of 900 Hz. It was found that the composite of silica aerogel and pulps could be a new sound absorbent because of high absorption capacity and durability which was due to hydrophobic effect on the surface of the composite.

Keywords:Silica Aerogel;Pulps;Sound Absorption;Absorbent
