Embodiment Construction

[0035] Below in conjunction with embodiment the present invention will be further described:

[0036] Fly ash environmental protection sound-absorbing board is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a fly ash composite foaming agent 3. There are 6 short steel pipes 5 designed in the built-in frame 2; 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, it is poured on the periphery of the built-in frame 2 with the fly ash composite foaming agent 3, and the built-in frame 2 is completely embedded in the fly ash composite foaming agent 3 After 4 days of standing and curing, the semi-finished fly ash environmental sound-absorbing panel is taken out of the mold and transported to the tunnel kiln for roasting. The roasting temperature is controlled at 550-650°C , the roasting time is controlled at 5 hours, and after cooling, it is packaged as a finished product ...

Abstract

The invention discloses an environmental-friendly flyash acoustic board. According to the technical scheme, the environmental-friendly flyash acoustic board is characterized in that a built-in frame is horizontally placed on a die, after each short steel tube in the built-in frame is inserted into the corresponding standing column, flyash composite foaming agent is poured on the periphery of the built-in frame to allow the built-in frame to be totally embedded inside the flyash composite foaming agent, and standing, curing, roasting and cooling are performed before the finished environmental-friendly flyash acoustic board is packaged. The flyash composite foaming agent comprises flyash, attapulgite argil powder, hydrogen peroxide and the like. The cured flyash composite foaming agent and the built-in frame form an integrity, so that overall strength, bending resistance and actual use effect of the environmental-friendly flyash acoustic board are improved, sound absorption and noise pollution control effects are enhanced, and functions such as thermal insulation, absorption and air purification are achieved. The environmental-friendly flyash acoustic board is suitable for being mounted in facilities such as highways, viaducts, city light rails, subways, factories, warehouses and public places.

Description

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