Abstract
A porous composite sound-absorbing material and a method for preparing the same are provided. The porous composite sound-absorbing material includes activated carbon cotton felt, zeolite particles, and an adhesive. The activated carbon cotton felt can bond the zeolite particles to fiber surfaces thereof by means of the adhesive, so that the zeolite particles are evenly dispersed and fixed and achieve optimal sound absorption performance. Meanwhile, a large number of micro-pore structures on surfaces thereof can act synergistically with the zeolite particles, so that the porous composite sound-absorbing material has significantly better sound absorption performance than the two and has extremely high cost performance. During the preparation process, the activated carbon cotton felt after treatments, is successfully compounded with the zeolite particles with more excellent sound absorption performance, so that the sound absorption performance is significantly improved and the cost performance is extremely high.
