Example Embodiment

[0041] The present invention will be further described below in conjunction with embodiments:

[0042] The non-burning serpentine foamed sound-absorbing panel is a rectangular plate-like body 1, composed of a built-in frame 2 and a serpentine cement foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 Lay it flat on the mold 4, after inserting the short steel pipe 5 in the built-in frame 2 into the column 6, use the serpentine cement foaming agent 3 to pour on the periphery of the built-in frame 2, and the built-in frame 2 is completely embedded in the serpentine cement foaming agent 3. After the inner part, it is a semi-finished product of non-burning serpentine foamed sound-absorbing panel; after 5 days of standing and curing, the semi-finished product of non-burning serpentine foamed sound-absorbing panel is taken out of the mold, and cured according to the conventional curing methods of cement products , 28 days later, the package...

Abstract

The invention discloses an unfired serpentine foaming acoustical board. According to the technical scheme, the unfired serpentine 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, serpentine cement foaming agent is poured on the periphery of the built-in frame, the built-in frame is totally inlaid in the serpentine cement foaming agent, maintenance is performed according to a conventional cement product maintenance method, and packaging is performed to form an unfired serpentine foaming acoustical board finished product; the serpentine cement foaming agent is prepared from serpentine, high-viscosity attapulgite clay powder, cement and other raw materials; the serpentine cement foaming agent and the built-in frame form an integrated whole after the serpentine cement foaming agent is cured, and thus the overall strength, the bending resistance and the actual using effect of the unfired serpentine foaming acoustical board are improved. The unfired serpentine 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 non-burning serpentine 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. The scope and extent of its noise is becoming more serious and affects the living environment of citizens Great, it has become one of the eye-catching urban environmental pollution problems. [0003] Sound-absorbing materials are usually used to produce some products such as sound-absorbing panels, sound-proof walls, sound-absorbing nets and silencers to control noise pollution. Some sound-absorbing materials are foamed to produce sound-absorbing panels and other products to improve product performance. [0004] At present, the foamed sound-absorbing panels on the market have a brittle texture, and the overall strength, bending...
