The present invention discloses a sound-absorbing ceramic and the manufacturing method thereof. The sound-absorbing ceramic is a multi-communicating-pore structured ceramic, mainly contains glass phase, quartz phase and Mullite phase; the raw material formula of sound-absorbing ceramic (percentage by weight) include: 15%~55% ceramic residue, 15%~25% clay, 1%~3% talc, 0.01%~10% quartz, 10%~45% feldspar, together with a proper amount of reinforcing agent, dispergator and water, as well as 3%~20% portland cement powder , or 3%~20% portland cement powder together with at least one decomposable inorganic salt. The sound-absorbing ceramic with multi communicating pores is achieved after high temperature burning. The sound-absorbing ceramic as described in the present invention owns a high sound-absorbing coefficient and a long service life as well as other characters including environment-friendly and healthy, fire prevention ability, moisture proof, water resistant, mothproof as well as anti-static and anti-ultraviolet. The manufacturing method of the said sound-absorbing ceramic in the present invention owns a low cost, simple and feasible, conductive to industrial productions. |
