Environment-friendly red mud acoustic panel

Abstract

The invention discloses an environment-friendly red mud acoustic panel. According to the technical scheme, the environment-friendly red mud acoustic panel is characterized in that a built-in frame is horizontally placed on a die, a red mud composite type foaming agent is poured on the periphery of the built-in frame after short steel tubes in the built-in frame are inserted into stand columns, the built-in frame is completely embedded into the composite type foaming agent, and the finished product of the environment-friendly red mud acoustic panel is obtained through packaging after standing, solidifying, roasting and cooling are conducted. The composite type red mud foaming agent is composed of red mud powder, attapulgite argil powder, hydrogen peroxide and the like. An integral whole is formed through the solidified composite type red mud foaming agent and the built-in frame, and therefore the overall strength, the bending resistance and the actual use effect of the environment-friendly red mud acoustic panel are enhanced, the effect of enhancing sound absorption performance and the effect of controlling noise pollution are improved, and the functions of heat preservation, adsorption and air purification are achieved. The environment-friendly red mud acoustic panel is suitable for being installed in facilities such as highways, viaducts, urban light rails, metros, factories, warehouses and public places.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a red mud 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...

AI Technical Summary

Problems solved by technology

A large amount of red mud cannot be fully and effectively utilized, and can only be stacked in a large area, occupying a large amount of land. The production of red mud has caused many direct and indirect impacts on human production and life, so the maximum It is imminent to reduce the output and harm of red mud and realize multi-channel and large-scale resource utilization
