Embodiment Construction

[0034] Below in conjunction with embodiment the present invention will be further described:

[0035] The basalt environmental protection sound-absorbing panel is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a basalt composite foaming agent 3. The built-in frame 2 is designed with 6 short steel pipes 5; the built-in frame 2 is placed on the mold 4 After the short steel pipe 5 in the built-in frame 2 is inserted into the column 6, the basalt composite foaming agent 3 is used to cast it on the periphery of the built-in frame 2, and the built-in frame 2 is completely embedded in the interior of the basalt composite foaming agent 3 to form a basalt environmental protection sound-absorbing board Semi-finished products; after 6 days of static curing, the semi-finished basalt environmental sound-absorbing panels are taken out of the mold and transported to the tunnel kiln for roasting. The roasting temperature is controlled at 600-700 ° C, and the roa...

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...
