Technical field
The present invention relates to ship's space noise control technique field, especially a kind of compound sound insulation of ship's space segmentation
Siding.
Background technique
Ship, the general name of various ships.Ship is to navigate by water or berth to carry out the vehicles of transport or operation in waters,
There is different technical performances, equipment and structural shape by different requirements.
Ship is a kind of man made transportation tools mainly run in geographical water.Internal mainly includes accommodation space, support
Structure and discharge structure have the propulsion system using the external or included energy.External form is usually to be conducive to overcome fluid resistance
Cleanliness envelope, material are constantly updated with scientific and technological progress, are in early days the nature materials such as wood, bamboo, fiber crops, modern age mostly be steel and
Aluminium, glass fibre, acrylic and various composite materials.
Cabin is generally divided into the room unit of inhabitation or work in building course by ship using compound sound insulationg board,
Compound sound insulationg board needs to meet a series of functions such as fire prevention, heat-insulated, heat preservation, sound insulation.
Currently, cabin shifting board uses 25mm and 50mm composite rock wool plate material in the market, structure type is two sides
Steel plate clips rock wool core materials, its main feature is that cheap, technical maturity；The disadvantage is that the rock wool density used is larger, about 150~
160kg/m3；Common 50mm composite rock wool slab sound-insulation value about 30~35dB is not able to satisfy MSC.337 (91) for habitation and lives
The demand of cabin oise insulation factor 35dB.
Currently, have polyimides, phenolic materials, roving glass fiber the materials such as fire-retardant nylon, aramid fiber honeycomb be widely used in
The fields such as building, traffic above-ground, but fire protecting performance is not able to satisfy B15 class requirement peculiar to vessel still.
Summary of the invention
The applicant provides a kind of compound sound insulation of ship's space segmentation for the disadvantage in above-mentioned existing production technology
Siding, so that bending stiffness is improved in the case where guaranteeing that compound sound insulationg board total structure thickness is constant, gross mass is constant, and
Weighted transmission loss is increased to 43dB from 35dB or so, substantially increases sound insulation effect.
The technical solution adopted in the present invention is as follows:
A kind of compound sound-insulation wallboard of ship's space segmentation, including lower panel, the lower panel top are provided with rock wool
Layer, the top spacing distance of the rock wool layer are provided with microperforated panel, mineral wool layer, glass are equipped with above the microperforated panel
Top panel is installed in the top surface of glass cotton layer, and the top panel is parallel with lower panel, and welds respectively in the two sides of top panel and lower panel
It is connected to side panel, meanwhile, the two sides of rock wool layer and mineral wool layer are Nian Jie with side panel, and the two sides of microperforated panel and side panel weld
It connects；Spacing between the top and microperforated panel of the rock wool layer forms air layer.
Its further technical solution is:
The top panel is identical with the structure of lower panel, is all made of galvanized steel plain sheet manufacture.
The thickness of the top panel and lower panel is 0.6mm.
The rock wool layer is with a thickness of 20mm, density 120kg/m3。

The air layer thickness is 5mm.
Uniform intervals are provided with multiple through-holes on microperforated panel, microperforated panel with a thickness of 0.6mm, the aperture of the through-hole is
3mm, the punching rate of microperforated panel are 15%.
Beneficial effects of the present invention are as follows:
Structure of the invention is compact, reasonable, easily manufactured, using mineral wool and rock wool as core material, is made using galvanized steel plain sheet
For panel, fixed mineral wool is constrained using microperforated panel, is air layer between rock wool and microperforated panel.It is empty in internal structure
Gas pay thickness is 5mm, and the thickness of rock wool and mineral wool is respectively 20mm and 23.2mm, and two sides panel is 0.6mm, microperforated panel
With a thickness of 0.6mm.The density of rock wool takes 120kg/m3, the density of mineral wool takes 64kg/m3, the bore dia of microperforated panel is 3mm,
Punching rate is 15%.
Structure of the present invention based on air sound wave transmit in transmission and reflectance mechanism, using two layers of material density,
The different structure type of thickness realizes impedance mismatching, and the planform of low density glass cotton is kept by microperforated panel, improves
The sound absorption effect of 1000Hz low frequency below, the final total oise insulation factor for improving structure.
Structure type of the present invention is simple, while improving the bending stiffness of siding, and weighted transmission loss is up to 43dB.
Top panel and lower panel of the present invention design are separately positioned on the top and most of entire compound sound-insulation wallboard
Low side, double-layer plate structure and internal core material composition sandwich composite construction have compared with great number bending stiffness, while oise insulation factor is also big
In the single sheathing structure of double thickness.
Top panel and lower panel of the present invention use galvanized steel plain sheet, can be with anti-corrosion.
Mineral wool layer of the present invention is a kind of inorfil, has small density, thermal conductivity Go-to-and-fro, heat preservation insulation, corrosion resistant
The advantages that erosion, stable chemical performance is a kind of common sound-absorbing material peculiar to vessel.The minimum compact density of mineral wool layer is less than rock
Cotton can increase the energy absorption during acoustic wave transmission, and control structure total weight using mineral wool layer.
It is multiple that air layer of the present invention can be such that sound wave occurs on air layer and mineral wool and rock wool layer interface
Reflection and transmission, increase energy loss, sound insulation property are made to have greatly improved.
The mineral wool of low-density can be constrained in microperforated panel of the present invention, and mineral wool layer deforms when preventing long-term upright
It collapses, keeps air layer thickness consistent；Microperforated panel and air chamber form perforation board resonance sound absorption structure, when incident acoustic wave frequency
When consistent with sound absorption structure resonant frequency, there is absorption peak, rock wool and mineral wool layer can increase sound sucting band width.
Rock wool layer of the present invention is a kind of inorfil, and thermal conductivity is low, heat preservation insulation, corrosion-resistant, chemical property is steady
The advantages that determining is a kind of common heat preserving and insulating material peculiar to vessel, it may have certain sound absorbing performance.It can be increased using rock wool layer
Energy absorption during acoustic wave transmission, and mineral wool and the inconsistent realization impedance mismatching of the density of rock wool, thickness are utilized, increase
Transmitting is added to lose.
Top panel of the present invention connects two sides panel with lower panel, which is formed an entirety, convenient for fortune
Defeated, storage and installation.
