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

Embodiment Construction

[0038] Below in conjunction with embodiment the present invention will be further described:

[0039] The cement foam sound-absorbing board is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a cement foaming agent 3, and 6 short steel pipes 5 are designed in the built-in frame 2; the built-in frame 2 is placed on the mold 4, After the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, it is poured on the periphery of the built-in frame 2 with cement foaming agent 3, and after the built-in frame 2 is completely embedded in the interior of the cement foaming agent 3, it is a semi-finished cement foam sound-absorbing board; After standing and solidifying, the semi-finished cement foam sound-absorbing board is taken out of the mold, cured according to the conventional maintenance method of cement products, and packaged as a finished cement foam sound-absorbing board.

[0040] The cement foaming agent batching is made up of fo...

Abstract

The invention discloses a cement foam sound-absorbing board. The main point of the technical scheme 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 cement foaming agent is used to pour the built-in frame around, and the built-in The frame is completely embedded in the cement foaming agent, and it is cured according to the conventional curing method of cement products, and it is packaged as a finished cement foam sound-absorbing board; the cement foaming agent is composed of cement, high-viscosity attapulgite clay powder, water and other raw materials; After the cement foaming agent is cured, it forms an integrated whole with the built-in frame, which increases the overall strength, bending resistance and actual use effect of the cement foam sound-absorbing panel. Cement foam sound-absorbing panels can not only effectively control noise pollution, but also have the functions of heat preservation and air purification; cement foam sound-absorbing panels are suitable for installation in highways, viaducts, urban light rails, subways, factories, warehouses, public places and other facilities .

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a cement foam 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 wall of the bu...
