Environment-friendly medical-stone sound-absorbing plate

Abstract

The invention discloses an environment-friendly medical-stone sound-absorbing plate. According to the technical scheme, an internal framework is flatly placed on a die, after a short steel tube in the internal framework is inserted into a stand column, composite medical-stone foaming agents are poured on the periphery of the internal framework, the internal framework is totally embedded in the composite foaming agents, and after standing curing processing, roasting and cooling, the internal framework and the composite foaming agents are packaged to form an environment-friendly medical-stone sound-absorbing plate finished product. The composite medical-stone foaming agents include medical-stone powder, attapulgite pot clay powder, hydrogen peroxide and the like. After being cured, the composite medical-stone foaming agents and the internal framework form an integrated whole, the integral strength, the anti-bending capacity and the actual use effects of the environment-friendly medical-stone sound-absorbing plate are improved, the effects of improving sound-absorbing capacity and noise pollution controlling capacity are achieved, and the functions of temperature preservation, adsorption and air purifying are achieved. The environment-friendly medical-stone sound-absorbing plate is suitable for being used for highways, viaducts, urban light rails, metros, factories, warehouses, public places and other facilities.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a medical stone 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 panel...

AI Technical Summary

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
