Environment-friendly basalt acoustic board

Abstract

The invention discloses an environment-friendly basalt acoustic board. According to the technical scheme, a built-in frame is horizontally placed on a mold; after short steel tubes in the built-in frame are inserted in vertical columns, composite basalt foaming agents are poured on the periphery of the built-in frame, and the built-in frame is completely inlaid in the composite foaming agents; and after the composite foaming agents are solidified in a standing manner, roasted and cooled, the built-in frame which is completely inlaid in the composite foaming agents is packaged to obtain the finished product of the environment-friendly basalt acoustic board. The composite basalt foaming agents consist of raw materials such as vesicular basalt powder, attapulgite clay powder and hydrogen peroxide; after the composite basalt foaming agents are solidified, the composite basalt foaming agents and the built-in frame form an integrated body, and the integral strength, the bending resistance and the actual using effect of the environment-friendly basalt acoustic board are improved; and the environment-friendly basalt acoustic board not only has an effect of strengthening sound absorption and controlling noise pollution, but also has functions of preserving heat, absorbing sound and purifying air. In addition, the environment-friendly basalt acoustic board is applicable to facilities such as an expressway, a viaduct, an urban light rail, a metro, a factory and a public place.

Description

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

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
