Volcanic ash environmental protection sound-absorbing panel

Abstract

The invention discloses a volcanic ash environment-friendly sound-absorbing panel. 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 columns, the volcanic ash composite foaming agent is used to pour the built-in frame around. 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 volcanic ash environmental sound-absorbing panel. The volcanic ash composite foaming agent is composed of volcanic ash powder, attapulgite clay powder and hydrogen peroxide and other raw materials; the volcanic ash composite foaming agent forms an integrated whole with the built-in frame after curing, which increases the overall strength of the volcanic ash environmental sound-absorbing panel, The anti-bending ability and practical use effect not only have the effect of enhancing sound absorption and controlling noise pollution, but also have the functions of heat preservation, adsorption and air purification. Volcanic ash environmental sound-absorbing panels are suitable for installation in highways, viaducts, urban light rail, subways, factories, warehouses, public places and other facilities.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a volcanic ash 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 panels...

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
