Abstract

The invention belongs to the technical field of sound-absorbing materials, and discloses an inorganic building sound-absorbing material and a preparation method thereof. The sound-absorbing material includes the following raw materials in mass percentages: 45-60% of modified aggregate, 15-30% of cement, Silica fume 10-15%, inorganic fiber 1-5%, foaming agent 1-10%, tackifier 3-5%; the modified aggregate includes modified porous ceramsite and modified expanded perlite, and The mass ratio of the modified porous ceramsite to the modified expanded perlite is 10:1-3; the cement is sulfoaluminate cement; the inorganic fiber is at least one of glass fiber or ceramic fiber; the foaming The agent includes at least one of sodium lauryl sulfate or fatty alcohol polyoxyethylene ether sodium sulfate; the thickener is polyethylene oxide; in summary, the hydrophobic modification treatment is carried out by using the modifier attached to the porous aggregate , so as to effectively improve the waterproof effect of the final formed sound-absorbing material, thereby avoiding the problem that the sound-absorbing material is affected by moisture during use.

Description

technical field [0001] The invention belongs to the technical field of sound-absorbing materials, and in particular relates to an inorganic building sound-absorbing material and a preparation method thereof. Background technique [0002] Sound-absorbing material is a functional material for building decoration. It has the dual requirements of sound absorption and decoration. It must be beautiful and meet the special requirements of sound absorption. Any material can absorb sound, but the degree of absorption varies greatly. It is usually a material with an average sound absorption coefficient greater than 0.2, which is listed as a sound-absorbing material. [0003] At present, the existing inorganic sound-absorbing materials in the market mainly include fiber-type sound-absorbing materials, granular sound-absorbing materials and foam-type sound-absorbing materials; among them, particle-type sound-absorbing materials are taken as an example, which have good sound absorption ...
