Example Embodiment

[0040] The present invention will be further described in conjunction with the following examples:

[0041] The non-burning fly ash foamed sound-absorbing panel is a rectangular plate-like body 1, composed of a built-in frame 2 and a fly ash cement foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 Lay flat on the mold 4, after the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the fly ash cement foaming agent 3 is used to pour the outside of the built-in frame 2, and the built-in frame 2 is completely embedded in the fly ash cement foaming agent 3. After the interior of the cement product, it is the semi-finished product of the non-burning fly ash foamed sound-absorbing panel; after the static curing treatment, the semi-finished product of the non-burning fly ash foamed sound-absorbing panel is taken out of the mold, and is cured and packaged according to the conventional curing methods of cement products ...

Abstract

The invention discloses a calcination-free foam acoustic absorption board made of fly ash. The technical scheme mainly includes that a built-in frame is flatly placed on a mould, foaming agents made of fly ash and cement are poured on the periphery of the built-in frame after short steel tubes in the built-in frame are inserted into upright columns, and the built-in frame is completely inlaid inside the foaming agents made of the fly ash and the cement, is maintained according to a conventional maintenance method for cement products and is packaged to form a finished calcination-free foam acoustic absorption board product made of the fly ash; the foaming agents made of the fly ash and the cement comprise raw materials such as the dry fly ash, high-viscosity attapulgite clay powder and the cement; the built-in frame and the foaming agents made of the fly ash and the cement form an integrated body after the foaming agents made of the fly ash and the cement are solidified, so that the integral strength, the bending resistance and an actual service effect of the calcination-free foam acoustic absorption board made of the fly ash can be improved. The calcination-free foam acoustic absorption board made of the fly ash has the advantages that noise pollution can be effectively controlled, and the calcination-free foam acoustic absorption board made of the fly ash further has heat insulation and air purification functions, and is suitable to be mounted in facilities such as highways, viaducts, urban light rails and subways and in public places.

Description

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