Abstract

The invention discloses a sound-absorbing board for buildings. The sound-absorbing board is prepared from raw materials in parts by weight as follows: 13-18 parts of thermoplastic phenol resin, 5-9 parts of gypsum, 3-8 parts of polyamide, 5-9 parts of polystyrene foam plastic, 1-2 parts of nano carbon black, 7-14 parts of coal gangue powder, 6-13 parts of collagenous fiber, 15-25 parts of glass bead particles, 20-30 parts of modified fly ash, 5-8 parts of dioctyl phthalate, 7-14 parts of montmorillonoid, 15-25 parts of expanded perlite, 2-3 parts of DBDPE (decabromodiphenyl ethane), 2-4 parts of potassium citrate, 0.5-1 part of sodium humate, 1-2 parts of a fire retardant and 1-2 parts of a water reducer. The sound-absorbing board for buildings has the advantages of being damp-proof, flame-retardant, flexible, light in weight, good in breathability, recyclable, non-toxic, harmless, good in sound absorbing effect, low in production cost and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a building sound-absorbing board and a preparation method thereof. Background technique [0002] Sound-absorbing panels refer to plate-shaped materials with sound-absorbing and noise-reducing effects, which are mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, gymnasiums, lecture halls, multi-functional halls, and hotel lobbies Hospitals, shopping malls, schools, piano rooms, conference rooms, studios, recording studios, KTV private rooms, bars, industrial plants, computer rooms, home noise reduction and other places that require high acoustic environment and high-end decoration. Existing sound-absorbing panel materials also have composite types, but few have excellent performance indicators for composites of inorganic materials and organic materials.
