Zeolite sound-absorbing material as well as preparation method and application thereof
The invention provides a zeolite sound-absorbing material. The macroscopic morphology of the zeolite sound-absorbing material is granular, the microstructure of the zeolite sound-absorbing material is characterized under SEM, it is visible that the zeolite sound-absorbing material has first particles and second particles growing on the surfaces of the first particles in an accumulation mode, the particle size of the first particles is 15-55 microns, and the particle size of the second particles is 25-545 nm. The prepared zeolite sound-absorbing material keeps a complete macroscopic morphology, and has a microstructure in which the first particles grow together in a staggered manner and the surfaces of the first particles are formed by closely packing and growing smaller second particles; the product has a rich porous structure, a large specific surface area, a wide aperture range and high mechanical strength.
本发明提供一种沸石吸音材料，所述沸石吸音材料宏观形貌呈颗粒状，在SEM下对所述沸石吸音材料的微观形貌进行表征，可见具有第一颗粒，所述第一颗粒表面上堆积生长的第二颗粒，所述第一颗粒的粒径为15‑55μm，所述第二颗粒的粒径为25‑545nm。制备的沸石吸音材料保持了完整的宏观形貌，均具有相互交错生长在一起第一颗粒，第一颗粒表面由较小的第二颗粒紧密堆积生长的微观结构，这样的产物具有具有丰富的孔洞结构、较大的比表面积和较宽的孔径范围以及较高的机械强度。
