Unburned attapulgite foam sound-absorbing board

Abstract

The invention discloses an unburned attapulgite foam sound-absorbing board. The technical scheme is characterized in that an internal frame is flatly placed on a mould, after short steel tubes in the internal frame are inserted into columns, an attapulgite cement foaming agent is poured on the periphery of the internal frame, the internal frame is totally inlaid in the inside of the attapulgite cement foaming agent, curing is carried out according to a conventional cement product curing method, and packaging is performed to form an unburned attapulgite foam sound-absorbing board finished product. The internal frame is inlaid in the unburned attapulgite foam sound-absorbing board finished product, and the attapulgite cement foaming agent is integrated with the internal frame into a whole after curing, so that integral strength, bending resistance capacity and actual use effect of the unburned attapulgite foam sound-absorbing board are improved. The unburned attapulgite foam sound-absorbing board can not only effectively control noise pollution but also has functions in thermal insulation and air purification; besides, the unburned attapulgite foam sound-absorbing board is suitable for being mounted in facilities such as highways, viaducts, urban light rails, subways, factories, warehouses and public places.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-burning attapulgite 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...

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
