Mould for producing environment-friendly flame-retardant acoustic boards

Abstract

The invention discloses a mould for producing environment-friendly flame-retardant acoustic boards. The technical scheme mainly includes that the mould for producing the environment-friendly flame-retardant acoustic boards is a rectangular mould, a positioning groove is welded in an upper plane of a bottom plate according to a designed positional dimension, vertical columns are mounted on the upper plane of the bottom plate according to designed relative positional dimensions, a frame is placed in the positioning groove, two handles are mounted in the middles of the outer sides of the left and the right of the frame respectively, and a lower plane of the bottom plate is placed on a vibration worktable. The environment-friendly flame-retardant acoustic boards are produced by the mould and integrated with an internal frame, the overall strength, the bending resistance and the practical use effect of the environment-friendly flame-retardant acoustic boards are greatly enhanced, the environment-friendly flame-retardant acoustic boards are directly mounted on wall surfaces of a building without drilling on a building construction site, time and labor are saved, and the mould is applicable to producing the environment-friendly flame-retardant acoustic boards in various facilities such as highways, subways and public places.

Description

technical field [0001] The invention relates to a mold, in particular to a 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 produced after foaming ...

AI Technical Summary

Problems solved by technology

[0005] Although there are many types of flame retardants and foaming agents and they are widely used, they have the disadvantages of insufficient performance and cannot meet the needs of actual production and environmental protection. The existing flame retardants and foaming agents do not have the function of purifying air.

[0006] 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
