Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation buildings, and particularly relates to a sound-absorbing material containing melamine foam. Background Art

[0002] In the use of metal profiles in the construction field, their sound insulation performance is relatively weak, and sound can propagate along their thickness direction, thereby causing noise pollution and affecting the quality of life of residents. Long-term exposure to a high-noise environment can lead to problems such as hearing damage and sleep disorders. Therefore, measures need to be taken in building design to reduce the noise propagation of metal profiles. Summary of the Utility Model

[0003] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a sound-absorbing material containing melamine foam to solve the problems put forward in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A sound-absorbing material containing melamine foam, including a plurality of sound-absorbing units, with melamine foam arranged between the plurality of sound-absorbing units; the sound-absorbing unit includes a first profile, a connecting piece, and a second profile; grooves are provided at the connection between the first profile and the connecting piece and at the connection between the second profile and the connecting piece; both ends of the connecting piece are provided with first protrusions matching the grooves.

[0006] Further, the first profile is in a frame shape, with a first profile cavity formed inside, and second protrusions for fixing the melamine foam are provided on the outer side wall of the first profile.

[0007] Further, sealant is provided at the connection of the plurality of sound-absorbing units.

[0008] Further, the second profile is in a plate shape.

[0009] Further, the connecting piece includes a plurality of sub-connecting pieces, and a cavity is formed between the plurality of sub-connecting pieces.

[0010] Further, a plurality of sound insulation columns are alternately arranged on the inner walls of the plurality of sub-connecting pieces.

[0011] Further, a sound-absorbing hole plate is provided inside the first profile cavity.

[0012] Further, there are a plurality of the sound-absorbing hole plates, and the sound-absorbing holes on the plurality of sound-absorbing hole plates are alternately arranged.

[0013] Further, the sound insulation columns and the sound-absorbing hole plates of adjacent sound-absorbing units are alternately arranged.

[0014] Furthermore, the sound insulation columns and the sound absorption perforated plates are both made of melamine foam.

[0015] The sound absorption material containing melamine foam in the present utility model has the following technical effects:

[0016] As a lightweight flame-retardant porous material, melamine foam has excellent sound absorption and noise reduction performance and flame retardancy. In terms of sound insulation, its porosity is as high as over 99%. Sound waves can easily and effectively enter the deep layer of the foam body and be converted into the vibration of the grid and consumed and absorbed, and the reflected waves can be effectively eliminated. In terms of flame retardancy, melamine foam itself has a high nitrogen content. After combustion, it immediately decomposes to produce a large amount of inert non-combustible gas nitrogen, thus isolating oxygen and slowing down the combustion speed. In the present utility model, melamine foam is arranged between the sound absorption units and inside the sound absorption units, which can effectively reduce the transmission of sound by the sound absorption material and improve the flame retardancy of the sound absorption material at the same time.
