Abstract:
The invention discloses a sound-absorbing material particle and a preparation method thereof. The preparation method comprises the following steps: step  1,  mixing a sound-absorbing raw material with a templating agent and water to prepare a sound-absorbing slurry, filling a reaction kettle with a porous ceramic substrate and the sound-absorbing slurry that are mixed together; step  2,  performing hydrothermal crystallization in the reaction kettle to ensure that the sound-absorbing raw material is crystallized on the porous ceramic substrate and constitutes the sound-absorbing material particle together with the porous ceramic substrate; step  3,  performing solid-liquid separation on the materials in the reaction kettle; and step  4,  drying and roasting the sound-absorbing material particle.

Claim (Index 7):
The preparation method according to  claim 1 , wherein after the step  4 , further comprising: step 5, performing surface grafting modification treatment on the sound-absorbing material particle.
