Definitions
- the invention relates to a sound insulation mat for floor coverings, especially hard floors such as parquet floors or laminate flooring, which is both impact sound insulation as well as room sound insulation.
- EP 1 001 111 A2 discloses a mat for sound insulation with a thickness of 3-5 mm, a basis weight of 2-3.5 kg / m 2 , the mat consisting of an adhesive based on polyurethane (PU) and small rubber parts.
- PU polyurethane
- PE Polyethylene
- EP 0 864 712 A2 describes a mat consisting of a flexible, thermoplastic material with viscoelastic behavior with a thickness of 1-3 mm and a minimum density of 2 g / cm 3 .
- EVA ethylene vinyl acetate
- Fillers with a density greater than 2.5 g / cm 3 are provided to adjust the mat density.
- the mat consists of adhesive and fillers. Mineral components such as lime, heavy spar and barium sulfate are disclosed as fillers.
- the adhesive can be, for example, polyethylene (PE).
- the impact sound insulation is said to be one Sound transmission to the underlying substructure, e.g. Screed, and subsequently on the reduce the space below. That's the way it is understandable that for this purpose flexible mats with a low density are advantageous.
- polyethylene cushioning film e.g. with a thickness of 2 to 5 mm
- cork mats wood fiber insulation boards
- the Impact sound insulation is intended to prevent the flooring has direct contact with the substructure, thus forms a sound bridge.
- bumps should of the subsurface.
- Room sound is understood to be the emission or reverberation of sound energy into the room located above the floor covering.
- energy is transferred to the floor by walking on it, which can be passed on in the floor and can thus be radiated as sound from the entire floor area into the room.
- Energy can also act on the floor in the form of sound waves, such as music or conversations, which can be reflected back into the room by reflection.
- the damping effect of the floor covering determines the ratio of incident energy to sound energy.
- the aim of room sound insulation is now to influence this damping effect in a suitable combination of flooring and insulation mat.
- the density and the viscoelastic behavior of both are the main influencing factors.
- Hard floor coverings, such as a laminate floor have a density of approx. 1000 kg / m 3 and a covering thickness between 5 and 14 mm.
- the sound insulation mat should now have a density that is well above 1000 kg / m 3 and also has a low modulus of elasticity.
- the invention is therefore based on the technical problem a sound insulation mat and a process for its manufacture specify with which both the impact sound as room sound insulation can also be improved.
- the sound insulation mat has a mat layer, which has a mat top and a mat bottom, the mat layer of natural raw material fibers, at least has a binder and high density particles.
- the high-density particles are inside the mat layer arranged inhomogeneously distributed and generate one from the bottom of the mat to the top of the mat increasing density distribution. Because of the strongly inhomogeneous On the one hand, the density profile is good impact sound insulation and on the other hand achieves good room sound insulation.
- the mat can be a simple thermal or material disposal after their use. This ideally applies even to a common one Disposal with the floor covering even in the event that this is a wood-based floor covering, e.g. Parquet flooring or laminate flooring.
- the inhomogeneous density profile preferably corresponds to one continuous function, d. H. there are no leaps in density and the density increases with the exception of the edge areas steadily from the underside of the mat to the top of the mat.
- the inhomogeneous density profile is preferably characterized by the following values.
- the density of the mat layer is greater than 300 kg / m 3 on the underside of the mat and greater than 1500 kg / m 3 on the underside of the mat.
- a high material density suitable for room sound insulation is thus present on the top of the mat facing the floor covering.
- the sound insulation mat has a lower material density in the area of the underside of the mat, which faces the substructure, for example the screed, so that the impact sound insulation is improved.
- the natural raw material fibers consist of wood fibers, flax fibers, Hemp fibers, sisal fibers, coconut fibers or fibers from other natural raw materials.
- the properties of the wood fibers correspond to those such as those used in the manufacture of MDF boards (medium density fibreboard) or HDF boards (Hardboard) are known.
- the fibers can e.g. obtained from a thermo-mechanical digestion from wood become.
- a production from waste materials such as Chipboard, fiberboard, OSB (Oriented Strand Board) or other wood-based materials is also conceivable and a thermo-mechanical digestion for the Manufacturing the fibers is not mandatory.
- wood fiber can also be other natural fibers, e.g. of annual plants like Flax, hemp, sisal or coconut can be used.
- Flax, hemp, sisal or coconut can be used.
- the defibration for this is much easier, it is usually a purely mechanical one Process.
- Wood fibers are due to their fiber diameter and their The length of the fiber is only suitable to a limited extent Form soundproofing mat.
- the wood fibers after their production as a binder so-called binding fibers mixed in, which is a good one To ensure matting of the wood fibers.
- the binding fibers can e.g. made of synthetic fibers (e.g. polyester fibers), from natural fibers (e.g. cellulose fibers) or from natural fibers (cotton, sisal, hemp, flax, coconut) consist.
- the proportion of binding fibers is dependent on their fiber length and fiber diameter between 1 and 20 percent by weight based on dry wood pulp.
- the binding fiber length Depending on the fiber properties, the Finished mat thickness and the possibilities of the mat forming system are in the range between 0.5 and 10 cm, the Binding fiber diameter can be between 2 and 10 dtex. However, longer or shorter, thicker ones can also be used or thinner binder fibers may be suitable.
- the unit 1 dtex corresponds to an average inside diameter, which adjusts itself when the fiber is weighing of 1 gram has a length of 10,000 meters.
- Adhesives are suitable as adhesives with thermosetting properties, e.g. amino resins, Phenoplasts, acrylates, with thermoplastic Properties such as Polyethylene, polyvinyl acetate, polypropylene, or with elastomeric properties, such as e.g. based on polyurethane, rubber, silicone. Natural adhesives, e.g. based on starch equally conceivable. A mixture of different adhesives to optimize the mat properties is also possible.
- the proportion of adhesive based on the dry wood mass is between 0.5 depending on the adhesive and 30 weight percent.
- Binding fibers adhesives or a combination thereof can be used. For example, adding an adhesive the wood fibers are completely dispensed with, if the required binding is made via the binding fiber.
- the high-density particles have a specific weight of greater than 2000 kg / m 3 .
- the particles can consist of a mineral substance such as chalk, quartz sand, barium sulfate, heavy spar, wood ash or the like.
- the high-density particles made of metals e.g. Aluminum, iron or the like exist.
- metals e.g. Aluminum, iron or the like.
- the high density particles are said to be during manufacture the sound insulation mat penetrate into it and, if at all, only to a small extent directly on the Mat surface come to rest.
- the ideal diameter or the grain size spectrum depends on the used Natural raw material fibers (wood fibers, natural fibers, binding fibers), the binding fibers used and / or the used Adhesives or the mixture of adhesives used from.
- the penetration behavior of the high-density particles in the mat can also be coordinated with a specific one Grain size spectrum or also over the elongated or spherical geometry of the small particles influenced become.
- quartz sand as a high density fabric e.g. an average grain size between 0.1 and 0.5, in particular 0.2 to 0.4 mm, was found to be particularly favorable.
- Weight fraction in the range between 30 to 300 weight percent based on the dry matter of the natural raw material fibers.
- the wood fibers and binding fibers are therefore in one first processing step into a, preferably homogeneous, Mix in the desired ratio and add a loose mat.
- the mat laying can either mechanically or in the Airlay process. The the latter procedure is used also for mat formation of non-woven mats and has also been used for Proven production of the mat according to the invention.
- the supply of the adhesive - if necessary - can be done during mat production. application techniques depending on the nature of the adhesive (solid or liquid) spray systems, litter box systems, Disc systems etc.
- the mat can then be solidified mechanically (for example by needling) or, if a thermoplastic adhesive is used, by the action of heat to a predetermined degree, with or without prior needling.
- the mat flows through an oven in which hot air flows through the mat between wire grids and is passed through pairs of calibration rollers.
- the mat is cooled with cold air under the melting area of the thermoplastic adhesive in order to bring the mat into a dimensionally stable state.
- the mat can also be heated, for example, by infrared radiation, microwave energy or high-frequency energy.
- ionizing radiation eg electron radiation
- Mats produced in this way have a density between 70 and 200 kg / m 3 and a basis weight between 500 and 3000 g / m 2 .
- the high density is sprinkled in Particle. These are sprinkled on the mat surface and e.g. by shaking from the top into the Depth of the mat introduced. Remaining on the surface Excess particles can, if necessary, e.g. removed by suction or other mechanisms become.
- the mat is actually solidified through the action of heat and pressure.
- it is advantageous to acting temperature clearly on the mat top to choose higher than on the mat underside.
- the press plate on the underside of the mat can also be advantageous, the press plate on the underside of the mat to cool.
- the acting temperature and the Press time must be chosen so that the used Adhesives can react.
- the acting temperature on the mat top is usually between 100 and 200 ° C, usually on the underside of the mat below 100 ° C.
- the individual manufacturing steps can be carried out immediately in a row. But it is also conceivable that separate manufacturing steps, temporally and locally, perform.
- the production of an endless mat up to the pressing is certainly to be aimed for, but one cyclical production is also possible.
- the pressing can either be cyclical for given mat formats or in a continuous manufacturing process e.g. with a double belt press or a calender system.
- the inhomogeneous density profile is therefore on the one hand by the one-sided scattering of high-density fabrics achieved.
- the last step in the process solidification taking place due to the unequal action from warmth to the top and bottom of the mat even the inhomogeneous distribution of the high-density particles can be achieved.
- the natural raw material fibers especially the wood fibers, can already during the fiber production with an adhesive in the blow-line process.
- An afterthought Application of adhesives after fiber drying is also conceivable and can be in front of or in In the course of mat formation.
- a required application of adhesives in particular glueing of the flax fibers, hemp fibers, Sisal fibers, coconut fibers or fibers from other natural raw materials can also during mat formation or beforehand in suitable gluing units.
- the adhesives can be in solid form, e.g. as a powder, or in liquid form, e.g. as a solution, dispersion or Emulsion applied to the fibers to be loaded become.
- Binding fibers and adhesive is an application of the adhesive on the binding fiber itself before the mat is formed possible.
- the adhesive can also be used in the course of mat formation either on the wood fiber and / or on the binding fiber be applied.
- the overall task of the adhesive is the fiber composite to solidify in such a way that a defined thickness of the sound insulation mat and the particles of high density embedded in the fibers are thus fixed are that during further processing and Laying the mat or during use Can’t remove particles from the mat.
- Fig. 1 shows a schematic representation of the Structural structure of a sound insulation mat according to the invention 2.
- This has a mat layer 4, which represents the actual material of the sound insulation mat 2.
- the Mat layer 4 has a mat top 6 and a Mat underside 8 on.
- When used as a sound insulation mat 2 is on the mat top 6 of the flooring (not shown) and on the mat bottom 8 the substructure of the floor (not shown).
- the mat layer 4 essentially has components Natural raw material fibers 10, a binder 12 (not shown structured) and high-density particles 14.
- the particles 14 are within the mat layer 4 arranged inhomogeneously distributed and generate one rising from the mat bottom 8 to the mat top 6 Density distribution on. 1 shows that the frequency distribution of the occurrence of the particles 14 in the area of the mat top 6 significantly larger than in middle area of the mat layer 4 and as in the area the underside of the mat 8. Otherwise the natural raw material fibers 10 and the binder 12 substantially homogeneous are distributed, results within the mat layer 4 the inhomogeneous density distribution.
- Fig. 2 shows an example of such a density profile of such an insulation mat.
- the density in the area of the underside of the mat - i.e. the side facing the substructure when installed - is around 300 kg / m 3 .
- Wood fibers or natural fibers with such a density are hardly consolidated with each other, so that the function of impact sound insulation can be very well fulfilled.
- the mat can still be deformed to a certain extent, which compensates for unevenness in the substructure.
- the density of the mat then increases steadily towards the top of the mat - in the exemplary case up to a density of approx. 2400 kg / m 3 just below the top of the mat.
- the increase in density is achieved on the one hand by the one-sided incorporation of high-density substances in the fiber matrix, and on the other hand by the production parameters of pressure and temperature.
- Example 1 The production of such an insulation mat is described in Example 1 below.
- 100 parts by weight of unglued wood fibers are mixed homogeneously with 1.0 part by weight of polyester fiber.
- the polyester fiber consists of a core fiber with a melting point above 160 ° C and a sheathing made of polyester with a melting range between 110 and 130 ° C.
- the polyester fiber has a staple length of approx. 50mm and a fiber diameter of approx. 5 dtex.
- the fiber mixture of wood fiber and binder fiber is formed into an endless mat in the airlay process and then needled to stabilize it.
- the intermediate product thus obtained has a weight per unit area of approx. 1500 g / m 2 and a thickness of approx. 12 mm.
- a soundproofing mat with a thickness of approx. 3 mm is obtained is very flexible and has a density profile corresponding to that Figure 1 has.
- the mat results in the full area on the Glued underside of a laminate floor board effective reduction of impact and room noise levels.
- a sound insulation mat is produced as in example 1.
- the mat is thermally consolidated, so-called thermobonding.
- Hot air at a temperature of around 180 ° C is passed through the mat in an oven and the thickness is set using calibration roller pairs.
- the result is an intermediate product with a basis weight of approx. 2500 g / m 2 .
- quartz sand is sprinkled in as described in Example 1 and the mat is compacted with analog press parameters.
- the density profile of the mat is almost identical, as are the acoustic properties.
- Example 3 describes the production of a sound insulation mat consisting of glued wood fibers and unglued Binding fibers based on cellulose fibers.
- 100 parts by weight the glued wood fibers are with 10 parts by weight Cellulose fibers mixed homogeneously and in the air-lay process shaped into a mat.
- the cellulose fibers have one Stack length of approx. 60 mm and have a fiber diameter of approx. 7 dtex.
- the mat becomes a solidification needled.
- Example 4 describes the production of a mat without the use of an adhesive.
- 30 parts by weight of hemp fibers (average length approx. 20 mm) are mixed with 70 parts by weight of wood fibers and 10 parts by weight of a binding fiber (cellulose fiber, length approx. 50 mm, fiber diameter approx. 7 dtex) and a loose mat is produced using the airlay process with a basis weight of 3000 g / m 2 100 parts by weight of quartz sand with a grain diameter between 0.2 and 0.4 mm are evenly distributed on the top of the mat and introduced into the depth of the mat by shaking.
- a fine fiber fleece based on cellulose fiber is placed on the top side, which prevents the quartz particles from loosening too much when needling.
- the mat produced in this way is then solidified by intensive needling.
- the thickness of the mat is approx. 8 mm.
- the density in the upper area of the mat is approx. 1600 kg / m 3 .
