Abstract
The invention discloses a sound-absorbing material particle and a preparation method thereof. The method for preparing the sound-absorbing material particle comprises: mixing a sound-absorbing raw material with a solvent to form a sound-absorbing slurry; filling the sound-absorbing slurry into a mechanical compression die, and performing compression molding on the sound-absorbing slurry to form a particle; performing a hydrothermal crystallization reaction on the particle to crystallize the sound-absorbing raw material in the particle; and drying the particle to produce the sound-absorbing material particle.
