Definitions
- the present invention relates to solutions for improving materials in the automotive and construction industries.
- the sound aspect is an important aspect because it allows the materials to filter out exterior noise in order to provide hearing comfort.
- An essential physical parameter for evaluating the acoustic performance of elastic panels is the sound transmission loss (STL) which is becoming an industrial design factor explored and studied in the field of acoustic materials.
- STL sound transmission loss
- the traditional design concept for low frequencies consists of increasing the acoustic surface mass and finding the compromise between weight and sound transmission loss (STL) for the lightness requirements demanded in practice.
- STL sound transmission loss
- STL can be greatly degraded by the well-known coincidence effect caused by the interaction of sound waves in the fluid-solid interface.
- An object of the present invention is to provide a material which makes it possible to have attenuation of sound transmission loss (STL) over the largest possible frequency band.
- the invention relates to a sound interlayer comprising a first layer made of a first material and a second layer, characterized in that the second layer comprises damping means comprising comprises at least one pellet made of a second material different from the first .
- the first layer comprises a sheet or a sheet of sheets.
- said first layer comprises at least one hole allowing said pellet to be inserted therein.
- the hole is through for a first layer comprising a sheet or a sheet of sheets, or blind for a first layer comprising a sheet of sheets.
- the second layer comprises a plurality of pellets, said first layer comprising a number of holes equal to the number of pellets so that each pellet fits into a hole.
- the pellets forming the second layer are connected to each other by clips to form a network.
- the pellets are heterogeneous in dimensions with a diameter varying from 10 to 50mm.
- the pellets are spaced from each other by a length of 0 to 40mm.
- the pellets represent at least 30% of the surface of the interlayer.
- the second material is chosen from the list comprising: metals or one of their alloy or oxide, ceramics, organic materials such as wood, materials of the mineral type such as glass, rock.
- the first material is a plastic of the polymer type, preferably a polyvinyl butyral (PVB) or a woven or nonwoven fabric based on natural or synthetic fibers such as hemp or flax or a textile based on glass fibers.
- PVB polyvinyl butyral
- the invention further relates to an insulation panel comprising at least a first substrate, characterized in that it further comprises an insert according to the invention arranged on said substrate.
- the panel comprises a second substrate, the first and the second substrate forming said panel.
- the panel comprises a second substrate, said interlayer being arranged to make the first substrate integral with the second substrate.
- each substrate is a sheet of glass.
- each substrate is a plate of the plaster or plywood type.
- FIG. 3 shows schematically an insert according to the invention in which the support comprises a sheet of sheets
- FIG. 5 shows schematically an insert according to the invention provided with a plurality of pellets
- FIG. 7 shows a diagram of the performance of different inserts including the insert according to the invention.
- FIG. 8 shows schematically an improved version of the arrangement of the tablets for the interlayer according to the invention
- FIG. 9 shows schematically a variant of the tablets of the insert according to the invention.
- the invention is shown.
- the invention is in the form of an interlayer I.
- This interlayer comprises a first layer 1.
- This first layer 1 is in the form of a support made of a first material.
- This support 1 comprises at least one sheet 10 as visible in FIG. 2.
- This sheet can be replaced by a sheet of sheets 11, that is to say that the support 1 can comprise several sheets assembled together as visible from FIG. 3.
- This interlayer I is used to be associated with at least one substrate S in order to form an acoustic insulation panel.
- the insert according to the invention further comprises a second layer 2.
- This second layer comprises damping means 20.
- damping means 20 are means for damping noise, comprise at least one pellet 21 or mass.
- This pellet 21 is made of a second material.
- This pellet 21 can take various shapes and comprises a lower face, an upper face and a wafer. The shape of this pellet is circular or oval or square or in a rhombus, rectangle, triangle or any regular shape as visible in FIG. 4.
- the profile of the pellet 21 is flat, that is to say that the lower face and the upper face are flat.
- At least the upper face or even the lower face can be curved, the curvature of the upper face and the curvature of the lower face are parallel or not, concave or convex.
- the curvatures are identical or reversed or different.
- This pellet 21 is then brought into contact with the support 1, that is to say with the sheet or the sheet of sheets.
- This combination of a support 1 and at least one pad 21 improves the sound performance of this insert I.
- the support 1 has mechanical properties, in particular an elasticity such that the sound waves of a certain frequency band are absorbed by said support.
- the first material of the support is a pastic like a polymer of the polyvinyl butyral (PVB) type or a woven or non-woven textile based on natural or synthetic fibers such as hemp or flax or a textile based on glass fibers.
- pellets 21 also act to improve the sound properties. This mass effect comes from the law of mass. Thus, each pellet 21 is able to enter into resonance along a dedicated frequency band as a function of its mass. This entry into resonance is due to the sound vibrations coming into contact with the pad 21.
- the second material of the pads is different from the first material of the first layer 1. This second material is chosen from the list comprising: metals or one of their alloy or oxide, ceramics, organic materials such as wood, materials of the mineral type such as glass, rock.
- the support 1 or the pads 21 each have their effect on the sound performance, the two elements combined also have an effect on the sound performance. This effect is the consequence of an inhomogeneity between the support and the pads, which reduces the coincidence effect and improves sound insulation performance.
- the sheet or sheets, making it possible to form said support 1 are made of a first material of the polymer or plastic or elastic type.
- the sheets may be made of the same material or be made of a different material in order to have different properties.
- the first material therefore exhibits acoustic properties, that is to say mechanical properties allowing sound vibrations to be absorbed.
- pellet 21 locally makes it possible to have an effect on the sound performance, for a larger surface, a single pellet is ineffective. For this, it is necessary to use a greater number of tablets 21.
- the pellets 21 are distributed over the surface of the support 1 to obtain an effect on the sound performance over the entire surface of the support as visible in FIG. 5.
- the positioning of the pellets is random or, preferably, regular. This regularity in the positioning of the pellets allows consistent acoustic performance to be obtained over the entire surface of the support.
- the density depends on the number of pellets per unit area and therefore therefore on the size of the pellets and their spacing.
- This density also affects the mass (kg) of the interlayer so that the higher the density, the heavier the interlayer will be. This heaviness can be disabling for the use of said interlayer.
- the spacing between the different pellets forming the second layer is between 0.5 and 5cm, preferably between 1 and 3 cm.
- the second layer 2 comprises a plurality of pellets 21 which are, preferably, all spaced from each other by the same interval. This spacing makes it possible to have pellets 21 positioned to form a grid or pellets arranged staggered as shown in Figure 6.
- the density also depends on the dimensions of said pellets 21.
- the shape of this pellet is circular or oval or square or in a rhombus, rectangle, triangle or any regular shape.
- the pellets have a diameter or a length or a width or a side length of between 5 and 20, preferably between 5 and 10mm.
- the diameter will be between 5 and 10mm while for a square pellet, the length of the sides is between 5 and 10mm, the same for a triangle or a rectangle or trapezoid.
- the shape and dimensions of the pellets are important, it is because, by the law of masses, the pellets are able to enter into resonance through sound vibrations, this resonance allowing an attenuation of external noise.
- the resonance does not take place at the same frequency or at the same frequency bands.
- a plurality of circular pellets with a diameter of 7mm do not have the same frequency or frequency bands as a plurality of pellets with a diameter of 18mm.
- the pellets are arranged to cover at least 30% of the surface of the support, preferably 40%. This minimum value of 30% makes it possible to have a sufficient mass to allow said pellets to enter into resonance when sound vibrations reach the insert according to the invention.
- the second layer 2 is arranged to allow acoustic filtration in a wider frequency band.
- the second layer is formed by a first series of pellets having a first shape of a first mass M1, a second series of pellets having a second shape and of a second mass M2 and so on.
- the law of masses allows a resonance of the pellets according to the sound waves. This resonance depends on the mass of said pellet 21.
- the operating range of the second layer is widened.
- Fig. 7 a diagram showing the level of sound transmission loss as a function of the frequency range is shown.
- This diagram shows that an interlayer whose pellets 21 are identical performs better than a conventional polymer interlayer film (here PVB) from 0 to 1000 Hz and around 2000 Hz but less efficient after 2500 Hz. Moreover, in this diagram of FIG. 7, it can be seen that for an optimized spacer, that is to say with pellets 21 of different shapes, the performance beyond 2500 Hz is better.
- PVB polymer interlayer film
- one possible arrangement is to have an alternation of lines made with the pads 21 of the first series and the pads 21 of the second series.
- Another example consists in having, for each row, an alternation of a patch 21 of the first series and a patch 21 of the second series.
- the pellets 21 of the first series and the pellets 21 of the second series are offset in order to have a staggered shape.
- the pellets 21 are arranged in the following form.
- the interlayer I is thus divided into a multitude of units, each unit being in the form of a square with a side 100mm.
- the total thickness is 0.8mm.
- This square is subdivided into four squares of 50mm side. These squares of 50mm side are named, from left to right and top to bottom, A, B, C D.
- Each square of 50mm side includes a pellet which is centered there. According to this preferred embodiment, the pellets of the different squares are not all identical.
- the unit is such that a first pair of pads positioned diagonally to each other are identical and that the other two pads, forming the second pair, arranged diagonally are different from each other and different from the pellets of the first pair.
- This arrangement thus makes it possible to have a unit therefore the acoustic performance covers a wide band.
- the performance of the pellets depends on the mass and therefore on the dimensions.
- the pellet of square A has a diameter of from 35 to 45mm, preferably 40mm.
- the pellets of squares B and C have a diameter of 25 to 35mm, preferably 30mm.
- the pellet of square D has a diameter of 15 to 25mm, preferably 20mm.
- the pellet in square A is 2.5 grams
- the pellets in squares B and C are 1.4 grams
- the pellet in square D is 0.6 g.
- the pellets 21 of a series are integral with one another. This securing of the pellets 21 is achieved by fasteners 22 between each pellet 21. These fasteners are preferably made of the same material as the pellets 21 so that the pellets and the fasteners 22 are in one piece. Thus the fasteners and the pellets are such that the pellets positioned to form the desired network.
- each series of pellets is in the form of an R network in which the pellets 21 are integral as shown in Figure 9.
- the arrangement of the different series between them is done by superimposing them on top of each other.
- To fix the networks R of pellets to each other they can be glued or mechanically fixed by staples.
- Another fixing solution consists in inserting the networks of pellets 21 between two sheets 10 or sheets 11 forming the support.
- the insert I is designed to be more compact. Indeed, if the acoustic performance is important, it is also desirable that the insert according to the invention is also the least restrictive. A constraint that can appear is that of the thickness which increases what deteriorates the compactness of the soundproofing panel.
- the support 1 is locally drilled as shown in Figures 10a and 10b.
- This local drilling consists in locally making at least one hole 12 on the support.
- This hole 12 is through or blind.
- the hole 12 is through when the support comprises a single sheet or a sheet of sheets.
- the hole is blind in the case of a support 1 comprising a sheet of sheets 11.
- hole 12 consists of cutting and removing layers, each layer being one of the sheets of sheet 11.
- the number of holes 12 is equal to the number of pellets 21.
- the total thickness of the insert I is the addition of the thickness of the support 1 and the thickness of the pellets 21 (zone A), the thickness of the thickest pellets 21 in the case of different series pellets 21 not necessarily having the same thickness.
- this variant cleverly allows not, locally, to accumulate the thickness of the pellets 21, the thickest in the case of several series of pellets 21, and the entire thickness of the support 1, especially in the case of a sheet of sheets 11.
- the total thickness of the interlayer is therefore reduced by the total thickness of the support (zone B) or by the thickness of at least one sheet of the sheet (zone C).
- pellets 21 integral with one another to form a network several configurations are possible.
- the support 10 is drilled over the entire surface of said network, that is to say at the level of the pellets 21 and the clips 22.
- the support 1 is drilled on the surface of said network at the level of the pads 21 or the clips 22 depending on whether the pads are thicker. as fasteners or vice versa.
- the thickness is reduced by interlocking means 23 as shown in Figure 15.
- the pads 21 of the two networks are arranged to form a grid, the pellets of the second network being arranged to be staggered with respect to the pellets of the first series.
- the clips 22 of the first series and the clips 22 of the second series overlap so that a clip of the first series and a clip of the second series one above the other form a cross.
- the interlocking means consist of a plurality of notches 24 arranged on the clips of at least the first series or the second series. These notches are, in particular, arranged on the faces of the fasteners of the first series or of the second series facing the fasteners of the other series.
- notches 24 arranged on the fasteners of the first series allow the fasteners of the second series to fit there.
- insertion is forced and requires high elasticity fastener material.
- the notches are not adjusted to each other, that is to say that a clearance exists between the two, then the insertion is done just by laying one network on the other, without strength.
- the notches are arranged on the fasteners of the two series.
- the first series includes notches only on the face of the fasteners facing the second series.
- the following series may include notches only on the face of the fasteners facing the posterior series. It will thus be understood that the fasteners of the second series include notches on the facing face of the third series and so on. However, it is possible that the series after the first series have notches on each side of the clips next to another series.
- This interlayer is then used to be associated with at least one substrate S to form an acoustic insulation panel P as shown in Figure 11.
- the interlayer according to the invention is used for a glazing application.
- the first material of the first layer 1 and the second material of the second layer 2 are preferably transparent.
- the Sound insulation panel comprises at least one sheet of glass used as a substrate.
- the spacer is associated with a single sheet of glass.
- the spacer is attached to the substrate by known means of attaching a polymer film to a sheet of glass.
- This sheet of glass is used alone as a sound insulation panel or it is used with a second sheet of glass.
- These two sheets of glass, one of which includes the insert, are associated in a frame so that an air space is present between the two sheets as shown in Figure 12. This association creates a so-called double glazing.
- the sound insulation panel comprises a first sheet of glass and a second sheet of glass.
- the insert according to the invention is then used to secure the two sheets of glass together. Laminated glazing is therefore created as shown in Figure 13.
- thickness control is important.
- the insulation board can be used in the construction industry for sound insulation of wall panels, floors and other surfaces.
- the substrate used is a plaster or plywood type plate with a thickness of at least 10mm.
- the insulation panel comprises at least one plate on which said insert according to the invention is placed. This insert can be placed between two plates.
