Abstract

The invention discloses a soundproof material and a preparation method thereof. The soundproof material comprises, by weight, 50-60 parts of alkali metal silicate, 20-25 parts of aluminum silicate fiber, 8-10 parts of polycrystal mullite fiber, 3-5 parts of mineral wool, 2-4 parts of ceramic hollow beads, 3-5 parts of expanded perlite, 1-2 parts of carbon powder and 1-2 parts of fly ash, wherein sodium silicate solid is preferably chosen as alkali metal silicate. Various fillers are added into an alkali metal silicate solution, a compact structure is formed inside a mixture when being subjected to microwave heating, and sound is difficult in transmission in the compact structure; the soundproof material is low in volume weight, so that plates manufactured by the soundproof material are light and convenient to transport and use.

Description

technical field [0001] The invention relates to a sound-insulating material, more precisely, to a sound-insulating material and a preparation method thereof. Background technique [0002] Sound insulation refers to the isolation, isolation, separation, etc. of sound or noise through certain objects, so sound insulation materials are needed. The number of decibels related to the incident sound energy on one side of a material relative to the transmitted sound energy on the other side is the sound insulation of the material, usually expressed by the symbol R (dB). Sound insulation materials or components will have different sound insulation effects due to different use occasions and different test methods. [0003] For sound insulation materials, in order to weaken the transmitted sound energy and block the transmission of sound, they cannot be as porous, loose, and breathable as sound-absorbing materials. On the contrary, their materials should be heavy and dense, such as st...
