Environment-friendly calcium carbonate acoustic board

Abstract

The invention discloses an environment-friendly calcium carbonate acoustic board. According to the technical scheme, an internal frame is flatly arranged on a mould, short steel pipes in the internal frame are inserted into upright columns, then calcium carbonate compound type foaming agents are poured in the periphery of the internal frame which is totally embedded in the compound type foaming agents, and after still standing and curing processing, roasting and cooling, a finished environment-friendly calcium carbonate acoustic board is formed through packaging. The calcium carbonate compound type foaming agents are composed of light calcium carbonate, attapulgite clay powder, hydrogen peroxide and other raw materials. After curing, the calcium carbonate compound type foaming agents are integrated with the internal frame, the integral strength, bend resistance and actual using effect of the environment-friendly calcium carbonate acoustic board are enhanced, the acoustic absorption effect and the noise pollution control effect are enhanced, and the environment-friendly calcium carbonate acoustic board has functions of heat preservation, adsorption and air purification. The environment-friendly calcium carbonate acoustic board is suitable for being mounted in highways, viaducts, urban light rails, subways, factories, warehouses, public places and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a calcium carbonate 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 p...

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
