Abstract
The utility model relates to a kind of underwater sound isolation baffle, comprise sound absorption baffle and the Antisoundbaffle being connected to the sound absorption baffle back side, the baffle that wherein absorbs sound is porosint, Antisoundbaffle is made up of the epoxy package of hard polyurethane foams sandwich layer and coated hard polyurethane foams sandwich layer, and described epoxy package has good water-fast and sound translative performance.When using in water, water can enter in the hole of porosint fully, and can be absorbed well by porosint foamed aluminium during sound wave incident, acoustic energy will well be converted into thermal effect and be predominantly absorbed.Take into account acoustic absorbant and reverse sound material performance separately, use rich aeriferous, light-duty, low-impedance rigid polyurethane foam as reverse sound material, can high water pressure resistant.There is good sound isolation effect.
Description
Technical field
The utility model relates to a kind of underwater sound sound insulating material goods, is specifically related to a kind of underwater sound isolation baffle.
Background technology
Underwater acoustic materials refers to the acoustical material used in facility under water, along with the appearance of nuclear-powered submarine and the development of Underwater Battery, undersea detection technology plays a part abnormal important, the quantity of nuclear submarine, capital ship, supertanker and combination vessel increases increasingly in recent years, thus also more and more higher to the requirement of underwater acoustic system and underwater noise control.Meanwhile, the kind of kuppe, sound transmitting window, baffle, reverberator, anechoic coatings and volume sound absorber is also on the increase, and this facilitates the development of underwater acoustic materials greatly.
Use under being in the condition of external pressure effect in the usual environment under water of underwater acoustic materials, therefore certain compressive resistance must be had.Current underwater acoustic materials relates generally to foamed material and elastomeric material etc., and compared with close material, the most outstanding feature of foamed material is that characteristic impedance is low, and this is that they obtain the main cause of application in underwater acoustic system.And elastomeric material is widely used in the underwater acoustic system being representative with submarine sound eliminating tile.Polyurethane underwater acoustic materials is the new polymers class underwater acoustic materials that development in recent years is got up, and the application in underwater acoustic system such as the foamed material of polyurethane and elastomeric material has good development prospect.
Underwater acoustic materials relates generally to the aspects such as underwater acoustic absorption material, underwater acoustic transmission material and underwater acoustic reflection material.But be only do single research for the material of a certain kind in the application of current underwater acoustic materials, it also only plays the effect of sound absorption, entrant sound or anti-sound in the application.
For this reason, deviser of the present utility model is because above-mentioned technological deficiency, by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of composite damping sound insulationg board, be compounded with the technique effect of sound absorption, entrant sound and anti-sound, to overcome above-mentioned technological deficiency.
Utility model content
The technical problems to be solved in the utility model is: design a kind of underwater sound isolation baffle, to solve the technological deficiency that underwater acoustic materials of the prior art can not meet request for utilization comprehensively.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of underwater sound isolation baffle, it is characterized in that: comprise sound absorption baffle and the Antisoundbaffle being connected to the sound absorption baffle back side, the baffle that wherein absorbs sound is porosint, Antisoundbaffle is made up of the epoxy package of hard polyurethane foams sandwich layer and coated hard polyurethane foams sandwich layer, and described epoxy package has good water-fast and sound translative performance.
Underwater sound isolation baffle as above, is characterized in that: described porosint is foamed aluminium.
Underwater sound isolation baffle as above, is characterized in that: the density of described hard polyurethane foams sandwich layer is 150-200Kg/cm
3.
Underwater sound isolation baffle as above, is characterized in that: described epoxy package material is epoxy vingl ester resin.
Underwater sound isolation baffle as above, is characterized in that: the thickness of described epoxy package is 3-8mm.
Known by technique scheme, a kind of underwater sound isolation baffle of the present utility model has following technique effect:
1. when using in water, water can enter in the hole of porosint fully, and can be absorbed well by porosint foamed aluminium during sound wave incident, acoustic energy will well be converted into thermal effect and be predominantly absorbed.
2. take into account acoustic absorbant and reverse sound material performance separately, use rich aeriferous, light-duty, low-impedance rigid polyurethane foam as reverse sound material, can high water pressure resistant.There is good sound isolation effect.
Detailed content of the present utility model obtains by following detailed description and Figure of description.
