Unburned zeolite foam sound-absorbing board

A technology of sound-absorbing panels and zeolite, which is applied in the direction of sound insulation, noise-absorbing devices, building components, etc. It can solve the problem of unsatisfactory use of the overall strength and bending resistance of the sound-absorbing panel, damage or shattering of the sound-absorbing panel, and the breaking and falling of the sound-absorbing panel and other problems, to achieve the effect of strong foaming ability, fast demoulding speed and uniform hole size

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

[0041] Below in conjunction with embodiment the present invention will be further described:

[0042] The non-burning zeolite foam sound-absorbing panel is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a zeolite cement foaming agent 3. There are 6 short steel pipes 5 designed in the built-in frame 2; the built-in frame 2 is placed flat on the mold 4, after the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the zeolite cement foaming agent 3 is used to cast it on the periphery of the built-in frame 2. Semi-finished foamed sound-absorbing panels; after static curing, the semi-finished non-burning zeolite foamed sound-absorbing panels are taken out of the mold, cured according to the conventional maintenance methods for cement products, and packaged as finished non-burning zeolite foamed sound-absorbing panels.

[0043] The zeolite cement foaming agent batching is made up of following components by weight percentage: p...

Abstract

The invention discloses an unburned zeolite foam sound-absorbing board. The technical scheme is characterized in that an internal frame is flatly placed on a mould, after short steel tubes in the internal frame are inserted into columns, a zeolite cement foaming agent is poured on the periphery of the internal frame, the internal frame is totally inlaid in the inside of the zeolite cement foaming agent, curing is carried out according to a conventional cement product curing method, and packaging is performed to form an unburned zeolite foam sound-absorbing board finished product. The zeolite cement foaming agent is composed of raw material such as zeolite, high-viscosity attapulgite clay powder and cement. The zeolite cement foaming agent is integrated with the internal frame into a whole after curing, so that integral strength, bending resistance capacity and actual use effect of the unburned zeolite foam sound-absorbing board are improved. The unburned zeolite foam sound-absorbing board can not only effectively control noise pollution but also has functions in thermal insulation and air purification; besides, the unburned zeolite foam sound-absorbing board is suitable for being mounted in facilities such as highways, viaducts, urban light rails, subways and public places.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-burning zeolite 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...
