| titleOfInvention | ZSM-5 molecular sieve for sound-absorbing material, its preparation method and obtained product |
| abstract | The invention provides a ZSM-5 molecular sieve used for sound-absorbing materials, a preparation method thereof and the obtained product, belonging to the technical field of molecular sieves. The present invention provides ZSM-5 molecular sieve with a silicon-alumina mass ratio of 800-4000, a specific surface area of micropores <72 m 2 /g, a range of micropore diameters between 0.5 and 1.5 nm, and a range of mesopore diameters between 2 and 10 nm. , and the ratio of the cumulative pore volume of micropores to the cumulative pore volume of mesopores is 0.24‑0.35. In the present invention, parameters such as the hydrophobic property, the ratio of micropore pore volume to mesopore volume, and the specific surface area of the sound-absorbing material are controlled within a better range by controlling the range of the silicon-aluminum ratio synthesized by the molecular sieve, so that the sound-absorbing material can be used in loudspeakers. The detuning frequency in the device is the best, and the device has the best anti-aging performance, so that it can better meet the application requirements of the loudspeaker, and has a broader application prospect. |
