Unfired diatomite foamed acoustic panel

Abstract

The invention discloses an unfired diatomite foamed acoustic panel. According to the technical scheme, a built-in frame is flatly arranged on a mould, diatomite cement foaming agents are poured on the periphery of the built-in frame after stand columns are inserted into short steel tubes in the built-in frame, the built-in frame is completely embedded inside the diatomite cement foaming agents, maintenance is carried out according to a regular maintenance method of cement products, and an unfired diatomite foamed acoustic panel finished product is packed; the diatomite cement foaming agents are formed by dried diatomite, high-viscosity attapulgite clammy powder, cement and other raw materials; the diatomite cement foaming agents and the built-in frame form a whole after solidification, and thus the overall strength, the counter bending capability and the actual using effects of the unfired diatomite foamed acoustic panel are improved. The unfired diatomite foamed acoustic panel can effectively control noise pollution and further has the functions of heat preservation and air purification. The unfired diatomite foamed acoustic panel is suitable for being mounted on facilities such as expressways, viaducts, urban light rails, metros and public places.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a non-burning diatomite foamed 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

[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
