Pyroclastic rock environmental sound-absorbing panels

Abstract

The invention discloses a pyroclastic rock environment-friendly sound-absorbing board. The key point of the technical proposal is that the built-in frame is placed flat on the mould, and after the short steel pipes in the built-in frame are inserted into the column, a pyroclastic rock composite foaming agent is used. It is poured on the periphery of the built-in frame, and the built-in frame is completely embedded in the interior of the composite foaming agent. After static curing, roasting and cooling, it is packaged as a finished pyroclastic rock environmental sound-absorbing panel. Pyroclastic rock composite foaming agent is composed of pyroclastic rock powder, attapulgite clay powder and hydrogen peroxide; after curing, the pyroclastic rock composite foaming agent forms an integrated whole with the built-in frame, increasing It improves the overall strength, bending resistance and actual use effect of pyroclastic environmental sound-absorbing panels. It not only has the effect of enhancing sound absorption and controlling noise pollution, but also has the functions of heat preservation, adsorption and air purification; it is suitable for installation on highways and viaducts , urban light rail, subway, public places and other facilities.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a pyroclastic rock environment-friendly 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 pa...

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
