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

Embodiment Construction
[0034] Below in conjunction with embodiment the present invention will be further described:
[0035]The talc environmental sound-absorbing panel is a rectangular plate-shaped object 1, which is composed of a built-in frame 2 and a talc 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, it is poured on the periphery of the built-in frame 2 with a talc composite foaming agent 3, and the built-in frame 2 is completely embedded in the inside of the talc composite foaming agent 3 to become a talc environment-friendly sound-absorbing board Semi-finished products; after 6 days of static curing, the semi-finished talc 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 roasting time is controlled at 6 ...

Abstract
The invention discloses an environment-friendly talc acoustical board. According to the technical scheme, the environment-friendly talc acoustical board is characterized in that a built-in frame is flatly placed on a mold; a talc compound type foaming agent is poured to the periphery of the built-in frame after a short steel tube in the built-in frame is inserted into a stand column; the built-in frame is completely inlaid inside the compound type foaming agent; after standing curing processing, roasting and cooling, a finished product of the environment-friendly talc acoustical board is formed through packaging. The talc compound type foaming agent is composed of talc powder, attapulgite argil powder, hydrogen peroxide and other raw materials; since the talc compound type foaming agent forms an integral whole with the built-in frame after being cured, the overall strength, bending resistance capability and actual using effect of the environment-friendly talc acoustical board are enhanced, the effects of enhancing sound absorption and controlling noise pollution are achieved, and the functions of heat preservation, adsorption and air purification are also achieved. The environment-friendly talc acoustical board is suitable for being installed on facilities in expressways, viaducts, urban light rails, subways, factories, warehouses, public places and the like.
Description
technical field [0001] The invention relates to a sound-absorbing board, in particular to a talc 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 the ...
