Abstract

The invention relates to a sound-absorption and noise-reduction material and a preparation method thereof. The sound-absorption and noise-reduction material comprises, by weight, 50-60 parts of PE resin, 6-10 parts of graphene, 12-16 parts of polypropylene fibers, 1-3 parts of stabilizer and 5-9 parts of foaming agent. The sound-absorption and noise-reduction material is prepared by sequentially subjecting the materials above to ball mill, foaming, extrusion granulation and the like. The sound-absorption and noise-reduction material and the preparation method thereof have the advantages that the PE resin can increase the elasticity of the sound-absorption and noise-reduction material to a certain degree, and the polypropylene fibers increase the hardness, wear resistance, corrosion resistance, tensile strength and ductility of the sound-absorption and noise-reduction material and allow the sound-absorption and noise-reduction material to be easily applied to construction; the sound-absorption and noise-reduction material is good in sound absorption and noise reduction performance and good in thermal insulation performance, and the whole wall face after construction is light and less prone to scaling; the preparation method is simple, easy to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of building noise reduction, and in particular relates to a sound-absorbing and noise-reducing material and a preparation method thereof. Background technique [0002] Sound absorption and noise reduction refers to the method of using sound-absorbing materials to absorb noise and reduce noise intensity. Generally, sound-absorbing devices (sound-absorbing finishes, space absorbers, etc.) are used to absorb the sound energy in the room to reduce noise. [0003] The sound energy at any point in the room is equal to the sum of the sound energy directly radiated by the sound source and reflected by the surfaces of the room to this point. Near the sound source, the direct sound energy dominates; far from the sound source, the reflected sound energy is dominant. The main function of the sound-absorbing device is to weaken the reflected sound energy, and its effect is closely related to the acoustic characteristics and layo...
