Definitions
- Flexible vibration damping track consisting of several layers as well as method and device for its production
- the invention relates to a flexible vibration damping sheet consisting of several layers, from which flat blanks for attachment to the inner surfaces of molded parts made of metal can be produced.
- the invention further relates to a method and an apparatus for producing such
- the vibration damping path in question is known in two different versions.
- the simplest version is referred to as a single-layer element or as a single-layer covering or as a deadening film.
- This vibration damping sheet consists of a binder based on plastic and / or bitumen, which are mixed with various fillers.
- the vibration damping sheet is coated to improve the adhesion on its underside, ie the surface contacting the inner surface of the molded part in the installed state with a hot melt or pressure sensitive adhesive with a basis weight between 0.01 and 0.13 kp / m 2 .
- the weight of the vibration damping track is between 2.3 and 11.0 kp / m 2. For a modern compact car, you need about 9 kp of this vibration damping track.
- the surface of the single-layer vibration damping sheet is coated with a thin one
- Antiblock layer from 0.003 to 0.03 kp / m 2 or an antiblock film equipped.
- this vibration damping layer which is to be viewed as a single layer, consists of three layers, the functional layer consisting of the plastic and the bitumen, however, containing more than 90% of the mass, generally even more than 97.5% of the mass.
- Such a vibration damping bar generally has the metal sheet to be damped, a viscoelastic intermediate layer and a cover layer. It is known to sandwich these sandwich elements from an adhesive layer made of elastomers, adhesive resins, waxes and partially of bitumen. men to manufacture.
- the cover layer should be as shear-resistant as possible and therefore preferably consists of a metal foil. Mainly aluminum foils or aluminum sheets, but also steel sheets are used. It is also known that a thermosetting plastic such as epoxy resin is used. It is also already known to use a film which has a magnetizable layer on the underside and a stiffening layer on the top.
- the basis weight of these materials is 4 kp / m 2 and more. Weight per unit area between 3 and 7 kp / m 2 is practical .
- the multilayer elements according to the prior art are several times more expensive than the single-layer elements.
- Multi-layer vibration damping sheets with a sandwich structure and a weight per unit area between 0.9 and 1.5 kp / m 2 are known in the laboratory, but due to the high price and the lack of recyclability in the laboratory
- the object of the invention is to design this vibration damping sheet in such a way that in particular the basis weight is reduced, and that these vibration damping sheets can be produced more cost-effectively than the previously known multilayer sheets, but the damping should in no way be worsened .
- the invention is also based on the object of demonstrating an inexpensive method which is simple to implement and a device which operates according to it in order to produce these multilayer vibration damping tracks.
- the object directed to the multilayer vibration damping path is achieved by forming the vibration damping path from at least three layers is that the outer layers are designed as a base layer and as a stiffening layer, and that a decoupling layer lies between the base layer and the stiffening layer.
- the basis weight now amounts to a maximum of 1.5 kp / m 2 and is thus approx. 35% lighter than the lightest vibration damping tracks used in automobile construction today. Due to the construction according to the invention, the need for the antiblocking layer and for the adhesive layer is furthermore significantly reduced or even unnecessary. Since the recipes mentioned above are based on bulk plastics, the significant weight reduction even leads to a cost reduction of this preferred embodiment compared to the lightest single-layer films or single-layer elements.
- the decoupling layer mainly contributes to the damping function, since it is subjected to high shear stress between the carrier plate and the stiffening layer.
- the vibration damping membranes in question are further processed as an anti-drone material for the interior cladding.
- Preferred areas of application are car bodies and housings for household dishwashers. These products are considered to be durable. It is therefore envisaged that the base layer, i.e. the
- Layer that directly contacts the inner surface of the component or possibly via an adhesive layer contains a share of at least 15% bitumen, and / or plastic, resins, oil and fillers, and that the remaining part is made of non-sorted recycling material, for example the lead frame when punching out the deadening parts.
- the manufacturer of the damping sheeting can manufacture or procure this non-sorted material himself, and it is put to use, so that either a time-consuming separation or disposal at a special waste landfill is not necessary.
- the non-sorted recycling material is therefore still used sensibly. So that the weight per unit area of the multilayer vibration damping path is kept as low as possible, but the damping effect is optimal, the weight per unit area of the base layer should be in the range of 0.63 kg / m 2 .
- the thickness of the base layer in the range of 0.5 mm. If necessary, the base layer can be filled with ferrite and magnetized.
- the decoupling layer can contain a relatively large proportion of bitumen. However, this is preferably between 0 and 30%. In addition, it contains a share of 2 to 8% of Oppanol, preferably Oppanol 50 and a share of Pangel which is between 2 and 8%.
- the decoupling layer also contains a proportion of a plasticizer that is between 3 and 15%. It also contains resins, the proportions of which are between 1 and 7%.
- the proportion of a wax is preferably between 2 and 6%.
- the proportion of an antioxidant should be less than 2%. However, the above proportions in their entirety result in a maximum value of 100%, so that the respective proportions can be varied accordingly. However, it is preferably provided that the proportions mentioned above are below 100% and that the remaining fraction is formed from a lime filler.
- the sum of the proportions of Oppanol and the plasticizer will be between 20 and 30%. It is also envisaged that the sum of the bitumen, oppanol and pangel fractions will be between 45 and 50% of the total. Finally, the sum of the proportions of plasticizers, resins and waxes is a maximum of 15%. It is also provided that the decoupling layer has a thickness in the range from 0.1 to 0.2 mm.
- the stiffening layer also consists of several substances. In a preferred one
- Design is provided that it consists of a mica, a recycled polystyrene, a fresh polystyrene ie polystyrene produced by polymerization, a plasticizer, resins, pangel and an antioxidant.
- the proportion of mica is preferably 15 to 30% of fresh polystyrene 40 to 70%, a resin proportion of 0 to 5%, a proportion of pangel of ⁇ 10% and finally a proportion of an antioxidant ⁇ 1%.
- the fresh polystyrene can be substituted up to 100% by recycling qualities. With the latter composition, a plasticizer can be dispensed with.
- the thickness of the stiffening layer should be a little bit less than that of the base layer and should be, for example, in the range of 0.40 mm.
- the vibration damping track is used especially for car bodies and housings in dishwashers.
- the base layer is provided with an adhesive coating on the side facing away from the stiffening layer.
- This adhesive coating is expediently formed from a hot melt adhesive, since plasticization by the action of heat is then possible. It is also advantageous that such adhesives have no solvents. The thickness of this
- Adhesive layer should be in the range of 0.02 mm.
- the stiffening layer can be provided with an antiblock layer on the outer side facing away from the base layer.
- the thickness of this antiblock layer is preferably in the range below 0.02 mm. This anti-blocking layer protects the stiffening layer from damage.
- the stiffening layer can also be produced according to another recipe.
- a thermosetting epoxy resin is used instead of thermoplastic polystyrene.
- This version is 10% lighter, although the acoustic properties can be regarded as equivalent.
- the higher manufacturing costs are disadvantageous, since the materials used are more expensive, as in the previously mentioned embodiments.
- the stiffening layer contains a proportion of Rütapox 0164 in the amount of 10 to 20%, a proportion of Rütapox VE 5156 IR in the amount of 15 to 30%, a proportion of mica in the amount of 20 to 40% Share of glass rovings in the amount of 5 to 20% and share of Pangel in the amount of ⁇ 10%.
- the total sum can of course also be only 100% in this embodiment, the proportions being compensated for by fluctuations within the stated values.
- the object directed to the method is achieved in that for producing a multilayer vibration damping web, in particular according to claim 1, the material mixture required for the production of the layers for each layer Vibration damping path is brought into a viscous state, so that this material mixture is conveyed through a line to a wide distributor and a flat layer is formed from each by means of a feed pump, and that the layers are brought together by means of a roller system.
- this multilayer structure can be produced even though the base layer and the stiffening layer are additionally filled with abrasive fillers.
- the viscosity of the stiffening layer is also higher than that of the decoupling layer.
- the wide distributor must be designed so that it can be adapted to different working widths, recipes and thicknesses.
- the volume flow for the respective layer is constant. This compensates for changes in the temperatures of the material mixtures, fluctuations in viscosity or density to the extent that the delivery volume via the drives of the delivery pumps remains stable in the event of pressure fluctuations. It is further provided that the thickness of the respective layer can be changed by changing the operating speed of the respective feed pump. The relation of the individual layers can be determined by the relation of the
- the object directed to the device is achieved in that the wide distributor for the stiffening layer is designed as a wide slot, the opening of which is directed onto the nip of two rolls which can be driven in opposite directions.
- the device is also designed so that the decoupling layer and the base layer can be driven by means of a further pair of rollers which can be driven in opposite directions. Layer can be generated.

- the pressure chamber could also be referred to as a cross-distributor, the volume of which is relatively large.
- a compression zone is created in which the materials are brought together.
