Application method of die for producing environment-friendly antiflaming acoustic board

Abstract

The invention discloses an application method of a die for producing an environment-friendly antiflaming acoustic board. According to the technical scheme, the application method is characterized by including the steps that the upper plane of a built-in framework is downwards flat placed on the frame of the die, after short steel tubes in the built-in framework are inserted in vertical columns, a composite antiflaming foaming agent is poured into the periphery of the built-in framework, and after the built-in framework is completely embedded in the composite antiflaming foaming agent, a semi-finished product of the environment-friendly antiflaming acoustic board is formed; after aging treatment, the semi-finished product of the environment-friendly antiflaming acoustic board is taken out from the die and conveyed to a tunnel kiln for roasting, and after roasting cooling, a finished product of the integrated concave-convex bar environment-friendly antiflaming acoustic board is packaged. The method is utilized to produce the environment-friendly antiflaming acoustic board, the environment-friendly antiflaming acoustic board and the built-in framework form an integrated whole, and therefore the overall strength, the bending resistance and the actual application effect of the environment-friendly antiflaming acoustic board are greatly improved. The application method is suitable for being utilized to produce various environment-friendly antiflaming acoustic boards for facilities of highways, subways, public places and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a method for using the mold for producing an environmentally friendly flame-retardant sound-absorbing panel. Background technique [0002] With the increasing awareness of global safety and environmental protection, people have higher and higher requirements for fire safety and flame retardancy of products. Halogen-free, low-smoke, low-toxic environment-friendly flame retardants have become the goal pursued by people. [0003] 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. [0004] 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 pr...

Problems solved by technology

[0005] 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, it will cause The sound-absorbing panels after drilling are broken and peeled off from the building wall
