Bauxite environmental protection sound-absorbing board

Abstract

The invention discloses a bauxite environment-friendly sound-absorbing panel. The key point of the technical solution 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 bauxite composite foaming agent is used to pour the Around the built-in frame, 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 product of bauxite environmental protection sound-absorbing board. The bauxite composite foaming agent is composed of high-alumina bauxite clinker powder, attapulgite clay powder and hydrogen peroxide and other raw materials; the bauxite composite foaming agent forms an integrated whole with the built-in frame after curing, increasing The overall strength, bending resistance and actual use effect of the bauxite environmental protection sound-absorbing board are improved. 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. Bauxite environmental sound-absorbing panels are suitable for installation in highways, viaducts, urban light rail, subways, factories, public places and other facilities.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a bauxite 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 on t...

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
