Abstract
The utility model discloses a stainless steel honeycomb perforated sound absorption board which comprises a panel and a honeycomb core arranged at the lower end of the panel, wherein a backboard is arranged at the lower end of the honeycomb core; the honeycomb core is a stainless steel honeycomb core; the panel, the honeycomb core and the backboard are bonded by an adhesive to form a stainless steel honeycomb interlayer structure; a layer of sound absorption cloth is pasted between the honeycomb core and the panel and backboard; perforation holes are formed in the panel and the backboard; the backboard and the panel have the same number of perforation holes. According to the stainless steel honeycomb perforated sound absorption board disclosed by the utility model, the honeycomb core in the honeycomb stainless steel is divided into multiple closed chambers, so that the airflow is prevented, the sound save is hindered, and then the sound absorption coefficient is improved; meanwhile, the strength of the board is enhanced, thus the size of a single board can be made larger, and the design freedom is further improved; the perforation rate can be changed by controlling the diameter and distance of the perforation holes according to the operation requirements.
Description
Technical field
The utility model relates to a kind of stainless steel honeycomb perforated acoustic board.
Background technology
In watercraft engine room, because machine sound is excessive, the sound panel therefore having needed, and the service life of sound panel and functional requirement are higher, because moisture in cabin is heavier, must adopt the material that is difficult for getting rusty, and intensity needs height, and lightweight.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of stainless steel honeycomb perforated acoustic board that stainless steel material is made, soundproof effect is good that adopts.
The utility model is achieved through the following technical solutions: a kind of stainless steel honeycomb perforated acoustic board, comprise panel, and be arranged on the honeycomb core of panel lower end, described honeycomb core lower end is provided with backboard, described honeycomb core is stainless steel honeycomb core, between described panel, honeycomb core and backboard, by adhesive, paste into stainless steel honeycomb sandwich, between described honeycomb core and panel and backboard, stick one deck sound-absorbing cloth.
As preferred technical scheme, on described panel and backboard, be provided with perforation, backboard is identical with the number of holes of panel.
As preferred technical scheme, described sound-absorbing cloth is nonwoven.
The beneficial effects of the utility model are: the utility model is because the honeycomb core in honeycomb corrosion resistant plate is separated into numerous closed cells, stoped Air Flow, sound wave is hindered, improved acoustic absorptivity, improve sheet material self intensity simultaneously, the size of monolithic sheet material can have been accomplished larger, further strengthened design freedom, by control punch aperture, pitch-row, and can according to requirements change punching rate.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is blast structural representation of the present utility model;
Fig. 2 is overall structure figure of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of stainless steel honeycomb perforated acoustic board, comprise panel 1, and be arranged on the honeycomb core 2 of panel 1 lower end, described honeycomb core 2 lower ends are provided with backboard 3, described honeycomb core 2 is stainless steel honeycomb core, between described panel 1, honeycomb core and 2 backboards 3, by adhesive, pastes into stainless steel honeycomb sandwich, sticks one deck sound-absorbing cloth between described honeycomb core 2 and panel 1 and backboard 3.
As preferred embodiment, on panel 1 and backboard 3, be provided with perforation 4, backboard 3 is identical with the number of holes of panel 1.
Wherein, sound-absorbing cloth is nonwoven.
The beneficial effects of the utility model are: because the honeycomb core in honeycomb corrosion resistant plate is separated into numerous closed cells, stoped Air Flow, sound wave is hindered, improved acoustic absorptivity, improved sheet material self intensity simultaneously, the size of monolithic sheet material can be accomplished larger, further strengthened design freedom.Can design according to room acoustics, carry out different punching rate designs, in certain scope, control the sound-absorption coefficient of combining structure, both reached design effect, can rationally control again cost, by control punch aperture, pitch-row, and can according to requirements change punching rate, backboard perforation requires identical with panel.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
