Embodiment Construction

[0043] Below in conjunction with embodiment the present invention will be further described:

[0044] The non-burning tailings foam sound-absorbing board is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a tailings cement foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 is laid flat On the mold 4, after the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the tailings cement foaming agent 3 is used to cast it on the periphery of the built-in frame 2, and after the built-in frame 2 is completely embedded in the inside of the tailings cement foaming agent 3, It is the semi-finished product of non-burning tailings foamed sound-absorbing board; after 5 days of static curing treatment, the semi-finished product of non-burned tailings foamed sound-absorbing board is taken out of the mold, and it is maintained according to the conventional maintenance method of cement products....

Abstract

The invention discloses an unfired gangue foaming acoustical board. According to the technical scheme, the unfired gangue 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, gangue cement foaming agent is poured on the periphery of the built-in frame, the built-in frame is totally inlaid in the gangue cement foaming agent, maintenance is performed according to a conventional cement product maintenance method, and packaging is performed to form an unfired gangue foaming acoustical board finished product; the gangue cement foaming agent is prepared from attapulgite clay gangue, high-viscosity attapulgite clay powder, cement and other raw materials; the gangue cement foaming agent and the built-in frame form an integrated whole after the gangue cement foaming agent is cured, and thus the overall strength, the bending resistance and the actual using effect of the unfired gangue foaming acoustical board are improved. The unfired gangue 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 non-burning tailings. 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 ...
