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

[0037] Below in conjunction with embodiment the present invention will be further described:

[0038] The zeolite environmental protection sound-absorbing panel is a rectangular plate-like object 1, which is composed of a built-in frame 2 and a zeolite composite foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; 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 composite foaming agent 3 is used to cast it on the periphery of the built-in frame 2, and the built-in frame 2 is completely embedded in the interior of the zeolite composite foaming agent 3 to form a zeolite environmental sound-absorbing board Semi-finished products; after 5 days of standing and curing, the semi-finished zeolite environmental protection sound-absorbing panels are taken out of the mold and transported to the tunnel kiln for roasting. The roasting temperature is controlled at 550-650...

Abstract

The invention discloses an environmental-friendly zeolite acoustic board. According to the technical scheme, the environmental-friendly zeolite 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, zeolite 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 zeolite composite foaming agent, and standing, curing, roasting and cooling are performed before the finished environmental-friendly zeolite acoustic board is packaged. The zeolite composite foaming agent comprises activated zeolite powder, attapulgite argil powder, hydrogen peroxide and the like. The cured zeolite 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 zeolite 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 zeolite 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 zeolite 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...
