Abstract
The invention discloses a composite type marine noise reduction structure, wherein a damping layer, a steel sheet or a steel plate and a dressing layer are sequentially laid on a horizontal steel deck. The combined-type structure provided by the invention can be used for greatly reducing educe or eliminating noises. The damping layer has better adhesive force, the damping and vibration reducing performances are good, the composite type marine noise reduction structure is shockproof, salt spray-resistant, sea water-resistant, hot-cold alternation-resistant, and is green and environmental-friendly protection; since the steel sheet or steel plate has high unit area mass, the material is heavy or compact, therefore, the sound insulation effect is excellent; the dressing layer can effectively protect the deck, so as to achieve heat insulation and light effects.
Description
Technical field
The present invention relates to ship deck structure, especially a kind of compound type denoising structure peculiar to vessel.
Background technology
The resolution that International Maritime Organization (IMO) (IMO) can pass through in the 91st Hai'an to close SOLAS Convention amendment came into force from 1 day July in 2014, " the noise level rule on ship " that requires construction of vessel to meet to approve recently, and with protection, personnel avoid noise injury.This rule is applicable to 1600 tonnes of above new ships, and the sound insulation between place of residence will take in, even to carry out in adjoining space activities such as music, talk, handling goods, still can be had a rest and amusement.The noise margin value in different places that rule is clear and definite, comprise that the weighted sound reduction index from accommodation to accommodation is 35, dining room, playroom, public place and from recreational area to accommodation and the weighted sound reduction index of Medical Treatment Room equal 45, weighted sound reduction index from corridor to accommodation equals 30, and the weighted sound reduction index from accommodation to the accommodation with traffic door equals 30.
Directly lay deck covering because these position existing structures in construction of vessel are above steel plate, be difficult to meet the requirement of IMO rule, thereby must transform existing these structures, could meet the rule request that IMO proposes.
Summary of the invention
Based on the problems referred to above, the object of this invention is to provide a kind of compound type denoising structure peculiar to vessel, be that a kind of sound insulation value is good, shock-resistant, salt spray resistance, nonflammable, light weight is wear-resisting, the compound type of environmental protection denoising structure peculiar to vessel.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of compound type denoising structure peculiar to vessel is laid with successively damping layer, steel disc or steel plate and dressing layer on the steel deck of level.
Described damping layer is SPUA layer, and thickness is 4 ~ 6mm.SPUA has good damping capacity, and adhesive ability is high, shock-resistant, salt spray resistance, sea water resistance, cold-hot alternately, environmental protection.
Described steel disc or steel plate are bonded on damping layer by damping adhesive, steel disc or steel plate are because having larger mass area ratio, material is heavy and closely knit, when sound wave incident, can only excite the microvibration of this interlayer, make the acoustic wave energy (transmission acoustic energy) to another space radiation very little, so noise insulation factor is large, defening effect is good.
Described damping adhesive is the graft copolymer of methyl methacrylate (MMA) and poly-chloroprene rubber (CR), gluing 2 ~ 3 times, and bondline thickness is 0.1 ~ 0.15mm.
Described dressing layer thickness is 40 ~ 45mm.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is composited by four layer materials, and compound after vibration and noise significantly weaken or eliminate.Damping layer adhesive ability is good, damping capacity is high, shock-resistant, salt spray resistance, sea water resistance, environmental protection; Steel disc or steel plate are because having larger mass area ratio, and material is heavy and closely knit, and therefore defening effect is splendid; Dressing layer comprises mineral binder bond and dressing main body, can effectively protect deck, reaches heat insulation and effect light weight.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are described further.
embodiment 1
As shown in Figure 1, a kind of compound type denoising structure peculiar to vessel is laid with successively damping layer 02, steel disc or steel plate 03 and dressing layer 04 on the steel deck 01 of level.
Steel deck 01 hardness is good, intensity is high.On steel deck 01, directly lay SPUA layer as damping layer 02, select the flame-retardant spraying polyurea elastic water-reducible finish of the commercially available trade mark for " rain rainbow " SPUA-352, thickness is 4mm.After the abundant dry solidification of SPUA, brush damping adhesive, steel disc or steel plate are bonded on damping layer by damping adhesive, obtain steel disc or steel plate layer 03.Damping adhesive used is the graft copolymer of methyl methacrylate (MMA) and poly-chloroprene rubber (CR), while applying steel disc or steel plate, and gluing 3 times, bondline thickness is 0.15mm.Finally lay dressing layer 04, the Ultralight dressing of selecting Taicang City Lanyan Deck Dressing Coating Co., Ltd to produce, this layer thickness is 45mm.
With reference to GB/T19889.10-2006 standard, the compound type making denoising structure peculiar to vessel to be tested, sound insulation weighted index is 46dB.
embodiment 2
Compound type denoising structure peculiar to vessel is identical with embodiment 1, difference is, on steel deck 01, directly lay SPUA layer as damping layer 02, select the flame-retardant spraying polyurea elastic water-reducible finish of the commercially available trade mark for " rain rainbow " SPUA-352, thickness is 5mm.The graft copolymer of methyl methacrylate (MMA) and poly-chloroprene rubber (CR), while applying steel disc or steel plate, gluing 3 times, bondline thickness is 0.1mm.Lay dressing layer 04, the Ultralight dressing of selecting Taicang City Lanyan Deck Dressing Coating Co., Ltd to produce, this layer thickness is 40mm.
With reference to GB/T19889.10-2006 standard, the compound type making denoising structure peculiar to vessel to be tested, sound insulation weighted index is 45dB.
