Burn-free rectorite foam sound-absorbing panel

Abstract

The invention discloses a fire-free rectorite foamed sound-absorbing board. The main 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 rectorite cement 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 rectorite cement foaming agent. It is cured according to the conventional curing method of cement products, and it is packaged as a finished product of non-burning rectorite foam sound-absorbing board; rectorite cement foam The agent is composed of rectorite, high-viscosity attapulgite clay powder and cement and other raw materials; after solidification, the rectorite cement foaming agent forms an integrated whole with the built-in frame, which increases the performance of non-burning rectorite foam sound-absorbing panels. Overall strength, bending resistance and practical use effect. Non-burning rectorite foam sound-absorbing panels can not only effectively control noise pollution, but also have the functions of heat preservation and air purification. Rectorite foam sound-absorbing panels are suitable for installation in highways, viaducts, urban light rail, subways, public places, etc. in the facility.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-fired rectorite foamed 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 the...

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
