Definitions
- the present invention relates to a soundproofing assembly, essentially intended for the soundproofing of substantially enclosed spaces, such as the passenger compartment of an automobile. the application of a plastic foam of high tortuosity to such soundproofing, and a method of manufacturing such a soundproofing assembly.
- the invention relates to acoustic problems that arise in a substantially enclosed space, such as the passenger compartment of an automobile, in the vicinity of noise sources such as a motor, the contact of tires with a road, etc.
- the acoustic waves are "damped" by materials in the form of single or double sheets (sandwich) or by a porosity and elasticity effect of a mass-spring system, in particular with vis ⁇ oelastic foam.
- a soundproofing system provides "insulation" when it prevents the entry of mid- and high-frequency sound waves into the soundproofed space, mainly by reflecting waves to sources of noise or the outside of the space soundproofed.
- a soundproofing system works by "sound absorption” (in the medium and high frequency range) when the energy of the acoustic waves dissipates in an absorbing material.
- the invention essentially relates to soundproofing in the range of medium and high frequencies.
- it is relatively simple to obtain good soundproofing at high frequencies with simple means, but in the field of medium frequencies (especially between 400 and 1000 Hz), the problem of soundproofing is all the more acute that the human ear is very sensitive in this frequency range.
- medium frequencies especially between 400 and 1000 Hz
- the noise in an enclosed space containing no noise sources is the result of the contributions of all acoustic sources, including the motor of an automobile, and the filtering due to the different actions of the soundproofing materials present.
- the soundproofing of a closed space is the result of numerous effects, and it is desirable to obtain a good compromise between the soundproofing obtained and the various means used to obtain this soundproofing. For example, it is not necessary to ensure a significant absorption of certain waves in the confined space if they have already been practically eliminated by the insulation.
- FIG. 1 shows an example of a mass-spring system conventionally used to provide insulation, particularly at the deck separating the passenger compartment from the engine compartment of an automobile.
- Reference numeral 10 denotes a support plate.
- a layer 12 of a spring-effect material such as a foam optionally having viscoelastic properties, carries a layer 14 of a "heavy mass" material, that is to say the layer representing the mass of the material. mass-spring system.
- a mass-spring system is known for the good insulation it provides.
- Reference 16 simply designates a decorative layer which has no functional effect in the case under consideration.
- GB-2 163 388 discloses such a mass-spring system whose heavy mass part comprises two layers.
- FIG. 1 The problem with the system shown in FIG. 1 is that, due to its low absorption, the heavy mass layer 14 must have a significant weight. Thus, layers having a density of about 3 to 7 kg / m 2 are commonly used. In addition, such a system is not very effective in the field of medium frequencies. As one seeks to lighten the cars for reasons of reduction of consumption, pollution, etc., a system as shown in FIG. 2 has been proposed, for example in the document WO 98/18657. In this system ⁇ to double permeability ", a porous decoupling layer 18 is in contact with the support sheet 10, preferably with partial interposition of air, and is surmounted by a microporous layer of reinforcement 20 and another porous layer 22, possibly with a decorative layer 16.
- the "heaviest" of the layers is a compressed phenolic felt, and the other a non-compressed flexible felt, the action of this system is due to its double permeability, that is to say, the difference in permeability between the porous layers.Its advantage is that it is light, but its disadvantage is that it ensures practically no insulation: it is therefore not suitable when such insulation is necessary re, for example for the apron of an automobile.
- a second group 24 of mass-spring type comprises a layer 28 of the heavy mass type associated with a layer
- This second group constitutes a conventional mass-spring system, but the mass of the heavy layer 28 and the thickness of the spring layer 26 are reduced, for example by one third to one half, with respect to
- the heavy mass type layer instead of having a density of 6.5 kg / m 2 , can have a mass per unit area of only 4 kg / m 2 . This reduction is possible thanks to the presence of the first group of layers 30.
- the first group comprises a porous layer 32, of the acoustic spring type, and an outer layer 34 which has a high resistance to the passage of air, and can also possibly be used as an active decoration layer for soundproofing.
- This outer layer 34 may be formed of a felt having a resistivity to the passage of air of the order of 3 to 20 times greater than that of the other layer 32.
- This system is therefore a kind of combination of the two systems described with reference to Figures 1 and 2, but with a significantly reduced weight compared to the first system through the lightening of the layer 28 of the heavy mass type, and a significantly increased efficiency compared to the second system thanks to the presence of the mass-spring system.
- the system shown in Figure 3 has excellent soundproofing properties because the group of layers 30, by its absorption effect especially at medium frequencies, offsets the weakest insulation effect provided by the system of the group of layers 24 .
- the invention therefore relates to the application of such a material to the soundproofing of confined spaces, and the application of this material to a soundproofing assembly having an operation similar to that described with reference to FIG. 3, and in which a mass-spring system is associated with a layer of high tortuosity foam.
- "Tortuosity” is a parameter commonly used for the characterization of porous materials.
- Acoustic absorption in porous media by D. Lafarge, Y. Auregan et al., Communication to the ONERA Congress , January 16, 2003. This document notably describes the effects of viscous friction, inertial mass effects, heat exchanges, and solid losses, and it refers to various parameters such as Darcy's permeability, tortuosity and characteristic length. viscous.
- tortuosity can be measured by determining the slope of the curve representing the variation of the square of the refractive index for the acoustic wavelength used as a function of the inverse of the square root of the frequency.
- tortuosity is related to the shape of the circulation paths in a porous material. Pores crossing rectilinearly a sheet with parallel faces in a direction perpendicular to these faces have a tortuosity equal to 1. Open cell foams commonly used have a tortuosity of between 1 and 1.35.
- a single layer of a foam having a tortuosity greater than 1.4, which can reach 3 is used. and preferably of the order of 2. It is the combination of high porosity (at least 0.9 and preferably 0.95) and high tortuosity (greater than 1.4) which gives these high sound absorption properties to this material.
- the invention relates to the application of an open-cell plastic foam with tortuosity greater than 1.4 to the soundproofing of substantially closed spaces.
- this foam advantageously forms a layer associated with a group of layers of type spring-mass comprising a layer having a viscoelastic heavy mass function and a spring layer.
- the invention also relates to a soundproofing assembly comprising superimposed layers, of the type which comprises a first group of layers having a good resistance to the passage of air, and a second group of layers with mass-spring function, the second group having a layer having a viscoelastic heavy mass function and a spring-like layer;
- the first group of layers comprises a layer of an open-cell foam of high porosity, high tortuosity and good resistance to the passage of air, this layer having, thanks to its high tortuosity, excellent sound absorption properties at medium and high frequencies.
- the first group of layers comprises only the layer of high tortuosity foam.
- the high tortuosity foam layer is elastic.
- the high tortuosity layer has an air flow resistivity of between 10 000 and 90 000 N. s / m 4 , and preferably of the order of 30 000 N. s / m 4 .
- the foam of the high tortuosity layer is formed of a plastic material selected from polyurethanes and melamine resins.
- the viscoelastic heavy mass layer has a mass at least one-third less than the mass of a heavy mass layer of a conventional heavy-mass, spring-loaded insulation system.
- the spring-like layer of the second group of layers has a tortuosity of at most 1, 4, and the high tortuosity layer has a tortuosity of between 1, 4 and 3, preferably of the order of 2.
- the spring type layer a vis ⁇ oelastic foam (for example with partially closed cells) which has the advantage of giving a structural damping in the low frequency range between 200 and 400 Hz and whose loss factor is of the order of 0.2 to 0.45, then that that of the high tortuosity layer is of the order of 0.1 to 0.2.
- the reduction of the insulation slope, ie the transmission losses, of this viscoelastic layer is compensated by the good insulation slope of the high tortuosity layer. It is advantageous for the soundproofing assembly to have a thickness greater than 20 mm.
- the soundproofing assembly may further comprise a decorative layer on the side of the high tortuosity layer.
- the invention also relates to a method of manufacturing a soundproofing assembly comprising superposed layers, the assembly being of the type which comprises a first group of layers having a good resistance to the passage of air and excellent properties of medium- and high-frequency acoustic absorption, and a second group of spring-mass-function layers, the second group comprising a layer having a viscoelastic heavy-mass function and a spring-like layer; the method comprises forming an initial assembly comprising at least one layer of each of the two groups, and heating the resulting assembly, heating at least one other layer than the initial assembly, stacking the initial assembly and the other layer, the arrangement of the stack in a pressing mold, and the association of the layers by pressing the stack.
- heating at least one other layer comprises heating a spring type layer.
- heating a spring-like layer comprises heating a felt.
- the first group of layers comprises a single layer, and the formation of the initial set comprises selecting, as a layer of the first group, a layer of an open cell foam of high porosity and tortuosity.
- FIGS. 1 to 3 already described, represent the structures of FIG. three known soundproofing systems; and
- Figure 4 is a schematic section of a soundproofing assembly according to the invention, disposed on a support plate.
- the reference 10 designates, as in the other figures, a sheet for carrying the soundproofing assembly according to the invention, for example an apron separating a motor compartment of a passenger compartment.
- This first comprises a second group 24 of layers comprising, as the system of Figure 3, a first layer 26 forming a spring and a second layer 28 forming a heavy mass.
- the first spring layer 26 is an open-cell flexible foam, for example of thermoplastic material, having good absorption and mechanical decoupling properties.
- the material of the layer 28, which is impermeable contains dense materials, such as waste bitumen, chalk, barium sulfate, linked by a thermoplastic material, for example a polyolefin such as polyethylene.
- Binder may also be an ethylene-vinyl acetate copolymer, or an ethylene-propylene-diene monomer terpolymer. This set may be similar to that shown in Figure 3.
- This second group of layers carries a layer 36, constituting alone a first group of layers and formed of a high tortuosity foam, such as a flexible foam polyurethane of porosity greater than 0.9 and tortuosity of 2.
- the high porosity foam and high tortuosity used according to the invention is preferably a polyurethane foam or melamine resin. It can be practically rigid, but it is preferably flexible.
- such a high tortuosity foam is prepared by making the polyurethane with an isocyanate / polyol ratio significantly higher than the commonly used values. These values depend on each isocyanate-polyol pair.
- the resulting foam has pores of irregular distribution, shapes and complex bonds. Its porosity is high, that is to say greater than 0.9, and preferably 0.95, this porosity being determined simply by the ratio of the weight of the foam and the weight of the corresponding non-porous material. Its resistivity to the flow of air is high, between 10 000 and 90 000 N. s / m 4 , and usually of the order of 30 000 N. s / m 4 .
- the system as represented in FIG. 1 (without the decorative layer 16) included a layer of polyurethane foam 12 having a thickness of 20 mm and having a basis weight of 1.2 kg / cm 2. m 2 .
- the heavy mass layer 14 had a basis weight of 6.5 kg / m 2 .
- the weight of a soundproofing element of 1 m 2 was therefore 7.7 kg.
- the layer 26 of spring-like foam of the same quality as in the system of Figure 1, had a thickness of 15 mm, and a basis weight of 0.9 kg / m 2 .
- the heavy-mass layer 28 had a surface mass reduced to 4 kg / m 2 . The reduction of the mass of this layer was thus accompanied by a reduction in the thickness of the spring foam layer.
- the third layer 32 consisted of a thermoplastic foam identical to that of layer 26, but with a lower thickness equal to 7 mm, and a surface density of 0.49 kg / m 2 .
- the outer layer 34 was formed of a felt 5 mm thick. The mass per unit area formed was 5.5 kg.
- the layers 26 and 28 were the same as in the preceding example, and the layer 36 was formed of a tortuosity polyurethane foam of 2, having a surface mass of 0.6 kg / m 2 and having a thickness of 10 mm. The mass per unit area achieved was also 5.5 kg / m 2 .
- the foams of the layers 12, 26 and 32 were the same layer of polyurethane foam with a density of 60 kg / m 3 .
- the known system described with reference to FIG. 1 had a weight of 1.1 kg / m 2
- the systems represented on the one hand in FIG. 3 and FIG. on the other hand in FIG. 4 had a weight of 5.5 kg / m 2 , a reduction of weight of 28% compared to the system of FIG.
- the assembly shown in FIG. 4 (excluding the sheet 10) can be manufactured in a single operation when the foam has been prepared and has only be associated, or in a single installation in two related operations, less expensive than two separate operations, when the high tortuosity foam is prepared at the same time.
- Figures 5 to 8 are sections illustrating the various phases of the method
- Figure 9 is a plan view of an installation for performing the following operations.
- the heavy mass layer 28 is laid on the high tortuosity foam layer 36 to form an initial assembly 42.
- the layer 28 comprises, on the opposite side to the foam layer 36, a hot melt material.
- the assembly 42 thus obtained is subjected to infrared heating in an infrared oven 44.
- a spring felt forming the layer 26 is heated in a hot air circulating oven 46, and is transmitted to form, together with the initial assembly leaving the oven 44, a sandwich assembly.
- preheated 48 comprises the two layers 28, 36 heated in the oven 44 surmounted by the spring layer 26 which has been heated.
- the preheated sandwich assembly 48 is transmitted to the mold 38, 40 of a press 50 which is under the control of an operator 52.
- the press 50 comprises, as indicated in FIG. 8, a lower mold 38, advantageously having channels vacuum transmission, and an upper mold 40.
- the mold 38, 40 used in the press 50 comprises an incorporated cutting device
- the parts of desired shape are directly obtained.
- the pieces leaving the press 50 are transmitted to a cutting apparatus 54.
- the method is also very advantageous when the first layer consists of a simple felt.
- the described method thus makes it possible to take advantage of the reduction in weight indicated above. It allows to make flat or shaped pieces.
- the installation used for its implementation can also be used in the case of the application of the method to four-layer soundproofing assemblies described above with reference to the aforementioned WO 03/069 596, and it allows or not the integration of the cutting system with the installation.
- the soundproofing assemblies according to the invention can be manufactured at a much lower cost than the assemblies shown in FIG. 3, and even a little less than or at least comparable to that of the assemblies shown in FIG.
