Unfired bauxite foamed acoustic board

Abstract

The invention discloses an unfired bauxite foamed acoustic board. The technical scheme is characterized in that an internal frame is horizontally placed on a mould, after short steel pipes in the internal frame are inserted into vertical columns, bauxite cement foaming agent is poured on the periphery of the internal frame, the internal frame is completely embedded inside the bauxite cement foaming agent, and the board is maintained according conventional cement product maintenance methods and packaged to form a finished product of the unfired bauxite foamed acoustic board. The bauxite cement foaming agent is composed of bauxite clinker, high-viscosity altapulgite clay powder, cement and the like. The bauxite cement foaming agent is cured and integrated with the internal frame, and integral intensity, deflection resistance and actual using effects of the unfired bauxite foamed acoustic board are improved. The unfired bauxite foamed acoustic board not only can effectively control noise pollution but also has functions of thermal insulation and air purification and is suitable for being mounted in facilities such as highways, viaducts, urban light rails, subways, public places and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-fired bauxite foamed sound-absorbing board. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0003] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and mufflers to control noise pollution, and some sound-absorbing materials are produced after foaming to improve product performance. [0004] At present, the texture of the foamed sound-absorbing panels sold on the market is relatively brittle, and the overall strength, bending resistance and use effect of the sound-absorbing panels are not ideal; in the process of installing the sound-absorbing panels on the w...

AI Technical Summary

Problems solved by technology

[0004] At present, the texture of the foamed sound-absorbing panels sold on the market is relatively brittle, and the overall strength, bending resistance and use effect of the sound-absorbing panels are not ideal; in the process of installing the sound-absorbing panels on the wall of the building, the sound-absorbing panels need to drill 4 on-site The above bolt holes are not only labor-intensive and time-consuming, but also increase the difficulty of construction, and it is easy to damage or shatter the sound-absorbing panel when drilling. When the sound-absorbing panel is installed on the wall of the building, due to the effect of gravity, drilling The sound-absorbing panels behind the holes are broken and peeled off from the building wall
