Abstract

The invention discloses an ecological shell acoustic panel and a preparation method thereof, belonging to the technical field of functional decoration materials for buildings. The ecological shell acoustic panel is prepared from the following raw materials by weight: 30 to 65 parts of blocky shell, 5 to 13 parts of shell powder, 5 to 13 parts of heavy calcium, 1 to 3 parts of sodium hexametaphosphate, 1 to 3 parts of guar gum, 0.5 to 3 parts of carrageenan, 0 to 10 parts of sodium alginate, 0 to 10 parts of water, 10 to 20 parts of paper pulp, 1 to 5 parts of dried Enteromorpha and 1 to 5 parts of a soluble glass adhesive. The ecological shell acoustic panel provided by the invention has high bending fracture load, good sound absorption effect and a noise reduction coefficient of greater than 0.25; the panel does not contain gypsum and is free of the phenomenon of swelling due to water absorption; the main component of the panel is shell, so the panel has excellent air permeability and moisture absorption and releasing performance and good mildew resistance and antibacterial effect and is applicable to a wet environment.

Description

technical field [0001] The invention relates to the technical field of architectural functional decoration materials, in particular to an ecological shell 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. [0003] Gypsum board is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one ...
