Definitions
- the present invention relates to a method for thermal insulation and sound insulation and / or sound insulation of metallic components and / or plastic components.
- the device container is in these cases usually made of thin stainless steel sheet with a typical thickness of about 0.4 mm.
- the application of the heavy foil primarily serves to increase the mass of the container wall.
- This approach is commonly referred to as "mass damping” and usually improves the acoustic properties of the device
- the usually very thin-walled sheet would, for example, due to the sustained water jet pulses to the inside of the washing container, excited as a resonating body to vibrate and the device becomes a very disturbing noise source in the household.
- the acoustic behavior of such devices is one of the main distinguishing features of individual products on the market in addition to the energy consumption and the quality of the rinsing or washing properties.
- Bitumen-based materials as derivatives of heavy oil, are not among the preferred materials used in areas where food is stored and prepared, as is the case in a household kitchen. Nevertheless, the classic mass damping with asphalt heavy foils continues to be used due to lack of cost-effective alternatives. Another disadvantage of asphalt films is that such heavy films are very good heat conductors and thus lead to increased heat losses.
- insulating layers have several advantages over the previously used asphalt films. First, they are, as already mentioned, toxicologically safe. In addition, they provide thermal insulation that minimizes energy loss in addition to a mass loss comparable to that achievable with asphalt heavy foil. Finally, they also offer an improved flame retardancy. In addition, the adhesion of the mass damping to the component can be improved by the construction according to the invention.
- the invention relates to a method for sound insulation and / or sound insulation of metallic components and / or plastic components, wherein in the method in a first step, an insulating layer of a foamed thermoplastic polymer first material is applied to the components and then from a mass attenuation layer a second thermoplastic polymer material having a density of 1, 5 to 5 g / cm 3 is applied by direct extrusion at melting temperatures between 120 and 300 ° C on the insulating layer as a defined profile.
- Metallic components are preferably thin-walled sheets of steel, aluminum and in particular stainless steel.
- Plastic components can be made, for example, of thin-walled PVC, Polycarbonate, polypropylene, acrylonitrile-butadiene-styrene (ABS) polymers or glass fiber reinforced plastics (GRP) exist.
- components to be coated are preferably components of so-called "white goods", ie household appliances or household appliances such as dishwashers, washing machines or bathtubs, shower trays, shower trays or sinks, but they can also be part of data processing equipment (computers), pump housings, compressors, be agricultural vehicles and equipment, medical equipment or housing chimneys of wind turbines.
- the coated components are the housing or the rinsing body of a dishwashing or washing machine, in particular a dishwasher.
- Such housing or flushing usually consist of stainless steel or in some cases also of polypropylene.
- Thermoplastic polymer materials for the purposes of this invention are pure thermoplastic polymers to which additional fillers, optionally reinforcing agents and / or other additives have been added.

Alternatively, the application can only take place on parts of the component. Likewise, the application of the mass damping layer can be made on all surfaces of a component, in particular on all surfaces that are already coated with the insulating layer. Alternatively, however, the ground damping layer can be applied only to parts of the surfaces of the component, in particular parts of the surfaces of the component which are coated with an insulating layer. In certain embodiments, the insulating layer may be at locations where additional material for mass damping, ie. the mass damping layer is applied, compressed and flattened, for example by means of pressing elements, such as pressure rollers.
- a 4mm thick foam sheet may be compressed to 1mm at the locations where the bulk cushioning layer is applied, and then the 3mm thickness of the cushioning layer applied so that the component is completely coated with a 4mm thick coating.
- the total layer thickness on the component is in various embodiments 3-6 mm, preferably about 4 mm.
- the foam sheet may have the desired thickness of 3-6, preferably 4 mm, outside the area of the cover with the mass cushioning layer, and in areas where a mass cushioning layer is applied, the foam sheet is previously compressed to such a thickness that after application the mass damping layer, usually in a thickness of 2-5, preferably 3 mm, the desired total thickness of 3-6, preferably 4 mm is obtained, ie For example, compression can be made to a thickness of 1 mm.

- temperatures in the range of 180 to 250 ° C are used in the extrusion of the second thermoplastic polymer material.
- the thickness of the bulk cushioning layer of second thermoplastic polymer material is usually 1 to 10 mm, preferably about 2 to 5 mm.
- the highly filled polymer material is preferably used in the form of granules.
- the granules also called pellets
- the grain size can be z. B. be determined by sieve analysis.
- the grain has a spherical or lenticular shape, but it may also be elliptical or cylindrical.
- the granules are to be surface free of adhesive or block free, so that sticking together to larger aggregates during storage and promotion of the granules is avoided.
- the polymer materials used may additionally contain as such known auxiliaries.
- the mass loss layer is applied by direct extrusion (DEX). This increases the degree of freedom of the device manufacturer, since no prefabricated heavy foils must be used. Instead, the position and the layer thickness of the coating can be chosen and set freely programmable.
- DEX direct extrusion
- Feeding the operational thermoplastic material to the extruder may be by gravity or pneumatic conveying systems. Under pneumatic conveying systems are understood in this context suction and / or blow conveyor.

- the robot can carry the extruder - including the preheater - and perform the relative movements. Similar robots are described for example in the documents US5358397, EP0787576 B1, DE10137214 A1.
- the manipulator When both component and extruder die are moving, the manipulator is preferably located stationarily adjacent to a conveyor belt, the manipulator moving the extruder mounted thereon or the extruder die only along two mutually orthogonal axes.
- the component to be coated is guided horizontally past the manipulator station on a conveyor device, this conveyor device optionally being provided with guide devices transverse to the transport direction, controlling the beginning and end of the extrusion of the coating material.
- the component to be coated is passed by means of a suitable robot to the nozzle of the extruder.
- the robot has up to 6 rotational or displacement axes.
- the specific embodiment of both the conveyor and the coating station depends on the size and geometry of the components to be coated. If the component to be coated is, for example, a complete washing container of a washing machine, a dishwasher or a housing cockpit, the design of the conveying devices for feeding the components to the coating station must be adapted thereto. The manipulator or robot carrying out the coating must also be designed accordingly. Such devices are already known for example from the automotive industry.
