Definitions
- Insulation materials for the absorption of sound waves and for thermal Insulation, especially for use in the automotive industry, is in the stand already known in technology.
- WO 97/45581 discloses an insulating fine fiber fleece produced using meltblown technology for damping sound waves for use in vehicle construction, which consists of homo- and copolymeric polypropylene and the one phenolic stabilizer to increase thermal resistance is added.
- the disadvantage is that the mechanical stability is due to low internal consolidation is not too high, so such a fine fiber fleece not easy to assemble, trade and assemble.
- the proportion of the stabilizing agent must be high so that the best possible Internal consolidation is achieved. This means that the variety is no longer guaranteed.
- sound absorbing and heat insulating components from the EP 0683280 known, predominantly from a composite of a nonwoven Plastic fibers - PET and PBT - with a laminated polyester film.
- DE 19821532 describes heat and sound-insulating cladding for covering the end wall of engine compartments or in the area of the transmission tunnel of motor vehicles. These are composed of an engine-side cover layer, which is formed from a fleece made of PES or glass or carbon or ceramic or mineral fibers, a thermosetting foam layer made of melamine resin, and an acoustically insulating layer made of plastic foam, composite particle foam or non-woven fabric made of native or synthetic fibers.
- the different material composition of such cladding enables no economic separation of raw materials and does not offer environmentally friendly Disposal after use.
- DE 4206411 deals with a sound-absorbing molded part for cladding Motor vehicles with a carrier layer made of open-celled flexible polyurethane foam, on which an open top layer of polyester nonwoven is laminated is, the flexible polyurethane foam with a thermosetting dispersion is impregnated.
- a disadvantage is the unpleasant odor nuisance caused by fogging for the occupants when using the parts in the interior of the passenger compartment due to the in the Chemicals contained in products, e.g. due to the contained flame retardants.
- DE 19708188 shows a soundproofing material made from nonwovens thermoplastic fibers, for example made of polyester fibers and in two Stages through a mechanical solidification process as well as one subsequent pressure / heat treatment is compressed. Through this Solidification a defined flow resistance range is reached.
- the soundproofing materials produced in this way have a thickness of only 0.3 to 3 mm and, in addition to having a rigid product character, therefore have a corresponding low thermal insulation.
- the invention has set itself the task, away from the known, rigid Insulation materials for the absorption of sound waves and for thermal Insulation to a flexible, soft sound and heat insulation material to get.
- the 2.2 dtex fiber that is used in the later thermal consolidation Binding fiber acts, has a significantly lower in the jacket area Melting point than the other two blend components that act as matrix fibers are provided.
- the homogeneously prepared mixture is fed to a card in the form of a fiber mat in order to form a fleece therefrom, which is paneled to the desired basis weight of, for example, 300 g / m 2 using a horizontal layer.
- the fleece passes through a needle machine for mechanical consolidation. In this case, needling is carried out on both sides. With the help of the method used and through the special selection of the needles used, which each have only one notch, the fleece is sufficiently internally consolidated, the softness and thickness of the material according to the invention not being adversely affected.
- the mechanical consolidation is followed directly by a thermal one Treatment in a dryer, so that the thus obtained inventive
- the end product has the properties of softness, heat insulation and sound absorption having.
- the fleece runs on a conveyor belt downstream of the needle machine a sieve drum dryer which heated and perforated two on the circumference Has sieve drums. During the dryer passage, hot air flows through a vacuum built up inside the sieve drums.
- the 2.2 dtex fiber softens superficial, becomes bindable and adhesive and forms binding sites on the Crossing points between binding and matrix fibers.
- the decisive factor for the production of the insulation material according to the invention is The fact that neither before nor during the cooling process no additional The nonwoven fabric is compressed or compressed. The fixation of the fleece happens only at the binding sites that are already during the Have trained dryer passage.
- this softness has a positive effect on the acoustic Properties, on the other hand based on the thermal insulation effect.
- the material adapts perfectly to three-dimensional contours, for example tools for the production of vehicle walls or covers on,
- the measured values for the weight-related bending stiffness in the longitudinal and transverse directions from Table 1 show the clear difference when comparing the insulation material according to the invention with a conventional insulation material. So it is much easier with the nonwoven according to the invention, a Contour adjustment to achieve because the nonwoven compared to the state of Technology has a smaller weight-related bending stiffness, less in itself is stiff.
- Table 1 shows the resulting weight-related bending stiffnesses for various basis weights, samples 1 to 3 of a nonwoven fabric produced according to the invention and sample 4 produced according to the prior art, which comprises 55% of a thermally bonded, needled nonwoven fabric made of 0.7 dtex PES matrix fiber and 2.2 dtex CoPES / PES bicomponent melt fiber describes 45%.
- the fleece For the further processing of the fleece according to the invention, it is important that, in addition to the softness, the fleece also has a structural strength. This Property is particularly critical when exposed to mechanical Stress, e.g. B. in handling, assembly and assembly. This is achieved in the nonwoven fabric according to the invention by the combination of needling on both sides and the subsequent thermal solidification by the hot melt adhesive fibers
- the strength measured which is a non-woven fabric split in the middle in its thickness of another Separation movement opposed.
- the sample holder Tear testing machine for example a Zwick 1425, clamped.
- the upper The sample holder is attached to the movable crossbar by means of a load cell appropriate. After the start of the test, the traverse settles at a constant speed Moving upwards, the nonwoven is separated, which on the Load cell applied force increases.
- DIN 54310 the mean measured force during a measuring path of 200 mm in N / 5cm specified.
- An essential factor for the thermal insulation ability of the insulation material according to the invention is the presence of numerous Cavities between the fibers.
- the air in the cavities significantly reduces the transport of Thermal energy from the side with the higher temperature to the side with the low temperature. This is of crucial importance Volume ratio between air and fiber in the nonwoven on the one hand and the Number of pores present, on the other hand, to cause cavitation enable.
- the proportion of air within the nonwoven is also for the insulation effect is important because the more air on the cavities, expressed in Volume ratio air to fiber is distributed, the better the thermal Insulating effect.
- the length and width are 100 mm, the height is the same as the thickness of the test specimen. It is important that the thickness is measured without compressing the test specimen. Depending on the thickness, this is done according to method B or C of EDANA 30.5-99.
- the specimen is dried to constant weight and weighed.
- 100% polyethylene terephthalate fibers were used, so that the density could be assumed to be 1.38 g / cm 3 .
- the acoustic effectiveness of the insulation material according to the invention in Comparison to a conventional insulation material is in the form of a Diagram.
- Airborne sound absorption depends on the angle of incidence, and in practice there is usually sound from all sides, which is also known as statistical sound incidence. In practice, the absorption over the reverberation time or determination of the equivalent absorption areas with and without the inserted insulation material. This results in the degree of absorption "Alpha”.
- the inventive Nonwoven fabric contain many voids, which reflect the sound waves within favor the nonwoven fabric of the invention.
- the sound is broken and optimally absorbed within the nonwoven fabric according to the invention.
