Sound-absorbing material particle and preparation method thereof
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.
