Unfired water-quenched slag foaming acoustical board

Abstract

The invention discloses an unfired water-quenched slag foaming acoustical board. According to the technical scheme, the unfired water-quenched slag foaming acoustical board is characterized in that a built-in frame is horizontally placed on a mold, after short steel pipes in the built-in frame are inserted into stand columns, water-quenched slag cement foaming agent is poured on the periphery of the built-in frame, the built-in frame is totally inlaid in the water-quenched slag cement foaming agent, maintenance is performed according to a conventional cement product maintenance method, and packaging is performed to form an unfired water-quenched slag foaming acoustical board finished product; the water-quenched slag cement foaming agent is prepared from water-quenched slag, high-viscosity attapulgite clay powder, cement and other raw materials; the water-quenched slag cement foaming agent and the built-in frame form an integrated whole after the water-quenched slag cement foaming agent is cured, and thus the overall strength, the bending resistance and the actual using effect of the unfired water-quenched slag foaming acoustical board are improved. The unfired water-quenched slag foaming acoustical board not only can be used for effectively controlling noise pollution but also has the functions of heat preservation and air purification and is suitable for being mounted in facilities such as expressways, viaducts, urban light rails, subways, public places and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a foamed sound-absorbing board with water-free slag. 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 th...

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
