Environmental-friendly attapulgite acoustical board

Abstract

The invention discloses an environmental-friendly attapulgite acoustical board. The key points of the technical scheme are that a built-in framework is flatly arranged on a die, a short steel tube in the built-in frame is inserted into a stand column, an attapulgite compound foaming agent is poured at the periphery of the built-in framework, the built-in framework is completely embedded in the compound foaming agent to stand, be cured, be roasted and be cooled, and the built-in framework is packed to form a finished product of the environmental-friendly attapulgite acoustical board. The attapulgite compound foaming agent solidifies to be integrated with the built-in framework. A semi-finished product of the environmental-friendly attapulgite acoustical board is roasted to greatly improve the whole strength, the bending resistance and the actual using effects of the environmental-friendly attapulgite acoustical board. Thus, the effects of sound absorption and noise pollution control are enhanced. The environmental-friendly attapulgite acoustical board further has the thermal-insulation, absorption and air-purifying functions. The environmental-friendly attapulgite acoustical board is suitable for being installed in facilities of highways, viaducts, urban light rails, subways, factories, warehouses, public places and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to an environmentally-friendly sound-absorbing board with concave-convex rods. 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...

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
