Description
Technical Field
The utility model relates to an acoustic panel. In particular to a high-efficiency sound-absorbing board integrating sound absorption and sound insulation. The method is particularly suitable for bulkheads and ceilings of engine cabins and working unit cabins of ships.
Background
At present, in order to reduce noise generated when a cabin engine and a working unit of a ship run, an acoustic board and a sound insulation board are mostly arranged in the cabin engine cabin and the working unit cabin, and although the acoustic board and the sound insulation board can reduce some noise, the installation is labor-consuming and time-consuming due to the fact that two boards are needed, and the installation cost is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the utility model is to provide a marine high-efficient abatvoix. The marine high-efficiency acoustic board saves labor and time and can reduce the installation cost.
The utility model discloses the above-mentioned problem that solves is realized by following technical scheme:
the utility model discloses a with high-efficient abatvoix, include backplate, panel and bordure the backplate is dull and stereotyped, its characteristics are: micropores are uniformly distributed on the panel. There are honeycomb panel, micropore board, soundproof cotton layer, polyimide layer in proper order between backplate and panel, have the isolation frame between all around on soundproof cotton layer and polyimide layer, the border of backplate, honeycomb panel, micropore board, soundproof cotton layer, isolation frame, polyimide layer and panel links together through borduring.
Wherein:
the face plate and the back plate are steel plates;
a sound absorption film is arranged between the panel and the polyimide layer, and the sound absorption film is a colorless and transparent polyurethane film;
the honeycomb plate is formed by connecting microtubes with hexagonal cross sections in parallel, and the longitudinal directions of the microtubes are parallel to the plate surface of the back plate;
the soundproof cotton layer is rock wool;
the isolation frame is formed by processing channel steel;
the back plate, the honeycomb plate, the micropore plate, the isolation frame, the soundproof cotton layer, the polyimide layer and the panel are glued together.
According to the scheme, the micropores are uniformly distributed on the panel. There are honeycomb panel, micropore board, soundproof cotton layer, polyimide layer in proper order between backplate and panel, have the isolation frame between all around on soundproof cotton layer and polyimide layer, backplate, honeycomb panel, micropore board, soundproof cotton layer, isolation frame, polyimide layer and inter-panel are glued together, and their border links together through borduring. By using one plate, the sound absorption and insulation effects can be achieved. Compared with the prior art in which the sound-absorbing board and the sound-insulating board are used for reducing noise, the installation time is saved, the time is saved, and the installation cost is greatly reduced.

Detailed Description
As shown in fig. 1 and fig. 2, the high-efficiency acoustic board for ships of the present invention includes a back plate 7, a face plate 1 and a covering edge 8. The back plate 7 is a flat plate, and micropores are uniformly distributed on the back plate. The composite honeycomb panel 6, micropore board 5, soundproof cotton layer 4, polyimide layer 2 have in proper order between backplate 7 and panel 1, and soundproof cotton layer 4 is provided with the isolation frame with polyimide layer 2 all around, link together through borduring 8 between the border of backplate 7, honeycomb panel 6, micropore board 5, soundproof cotton layer 4, isolation frame 3, polyimide layer 2 and panel 1.
Wherein, the panel 1 and the back plate 7 are both steel plates; the panel 1 can be made of stainless steel plates. The soundproof cotton layer 4 is rock wool, and the isolation frame 3 is formed by processing channel steel.
In order to improve the sound absorption effect, a sound absorption film is provided between the panel 1 and the polyimide layer 2. The sound absorbing film is a colorless and transparent polyurethane film, and is attached to the back surface of the panel.
The honeycomb plate 6 is formed by connecting microtubes with hexagonal cross sections in parallel, and the longitudinal directions of the microtubes are parallel to the plate surface of the back plate 7.
The back plate 7, the honeycomb plate 6, the microporous plate 5, the soundproof cotton layer 4, the isolation frame 3, the polyimide layer 2 and the panel 1 are glued together. Wherein: the back plate 7 and the honeycomb plate 5 are compounded together by 3012 type epoxy glue, the honeycomb plate 5 and the micropore plate 5 are compounded together by 3012 type epoxy glue, the micropore plate 5 and the soundproof cotton layer 4 are compounded together by PAPU-30 type adhesive, the soundproof cotton layer 4 and the polyimide layer 2 are fixed together by PAPU-30 type adhesive and screws, and the polyimide layer 2 is compounded with the panel 1 by the PAPU-30 type adhesive and the sound absorption film.
The cross section of the covered edge 8 is in a groove shape, and the covered edge is made of stainless steel. The back plate 7, the honeycomb plate 6, the microporous plate 5, the soundproof cotton layer 4, the isolation frame 3, the polyimide layer 2 and the periphery of the panel 1 are fixed together through a wrapping edge 8.
