A sound absorption material preparation method, a sound absorption material and a filling method thereof. The preparation method comprises: S1, preparing a non-foaming material slurry; S2, producing a flammable material framework and a cover-shape container, and placing the flammable material framework into the cover-shape container; S3, forming the non-foamed material slurry in the cover-shape container to form a wet formed body; S4, drying the wet formed body to form a dry formed body; and S5, calcining the dry formed body, wherein the flammable material framework is burned off during the calcining step to form connected three-dimensional channels in the sound absorption material. The preparation method is simple in operation. Connected three-dimensional channels are formed in the sound absorption material so that the sound absorption effect is improved. The sound absorption material is prepared by the preparation method, has connected three-dimensional channels therein, and has a good sound absorption effect. The filling method comprises first pre-forming the sound absorption material and then filling same into a space to be filled, so that the sound absorption material fully fills the space to be filled. |
