Definitions
- the invention relates to a sound insulation mat for floor coverings, in particular hard floors such as e.g. Parquet floors or laminate flooring, which provides both impact sound insulation and 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.
- BESTATIGUNGSKOPIE DE 299 08 733 U1 describes a mat with a thickness of 1-6 mm and a weight per unit area between 0.8 and 1.95 kg / m 2 per mm of layer thickness.
- 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 intended to transmit sound to the substructure underneath, e.g. Screed, and subsequently reduce to the space below. So it is understandable that flexible mats with a low density are advantageous for this purpose.
- polyethylene padding films e.g. with a thickness of 2 to 5 mm
- cork mats e.g. with a thickness of 2 to 5 mm
- wood fiber insulation boards e.g. with a thickness of 2 to 5 mm
- mats consisting of textiles e.g. forming a sound bridge.
- unevenness in the subsurface should be compensated.
- Room sound is understood to be the emission or retroreflection of sound energy into the room located above the floor covering.
- energy is transferred to the soil by walking on it, which can be passed on in the soil and thus from the entire soil surface in the room as sound can be radiated.
- 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 the incident energy to the emitted sound energy.
- the aim of room sound insulation is 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 laminate floors 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 of specifying a sound insulation mat and a method for its production, by means of which both the impact sound insulation and the room sound insulation are improved.
- the technical problem indicated above is inventively achieved by a sound insulation mat for floor coverings, in particular for parquet floors and laminate floors with the features of claim 1. Further developments of the invention are specified in the subclaims.
- the soundproofing mat has a mat layer which has a mat top and a mat underside, the mat layer having natural raw material fibers, at least one binder and high-density particles.
- the high-density particles are arranged inhomogeneously distributed within the mat layer and produce a density distribution increasing from the mat underside to the mat top. Due to the strongly inhomogeneous density profile, good impact sound insulation is achieved on the one hand and good room sound insulation on the other hand.
- the mat can be easily disposed of thermally or material after it has been used. This ideally even applies to joint disposal with the floor covering itself, in the event that this corresponds to a wood-based floor covering, for example parquet flooring or laminate flooring.
- the inhomogeneous density profile preferably corresponds to a continuous function, i. H. there are no jumps in density and, with the exception of the edge areas, the density increases continuously 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 known, for example, from the production of MDF boards (medium density fiberboard) or HDF boards (hard fiberboard).
- the fibers can e.g. can be obtained from a thermo-mechanical digestion made of wood.
- a production from waste materials such as Chipboard, fiberboard, OSB (Oriented Strand Board) or other wood-based materials are also conceivable and a thermo-mechanical disruption for the production of the fibers is not absolutely necessary.
- binding fibers are added to the wood fibers after they have been produced as binders, which are intended to ensure good matting of the wood fibers.
- the binding fibers can e.g. consist of synthetic fibers (e.g. polyester fibers), natural fibers (e.g. cellulose fibers) or natural fibers (cotton, sisal, hemp, flax, coconut).
- synthetic fibers e.g. polyester fibers
- natural fibers e.g. cellulose fibers
- natural fibers cotton, sisal, hemp, flax, coconut
- the proportion of binding fibers is between 1 and 20 percent by weight based on the dry wood pulp.
- the binding fiber length can be between 0.5 and 10 cm
- the binding fiber diameter can be between 2 and 10 dtex.
- longer or shorter, thicker or thinner binding fibers can also be quite suitable.
- the unit 1 dtex corresponds to an average inside diameter that is established when the fiber with a weight of 1 gram has a length of 10,000 meters.
- the addition of a binder in the form of an adhesive may be necessary in the course of the production which is described below.
- Suitable adhesives are adhesives with thermosetting properties, such as aminoplasts, phenoplasts, acrylates, with thermoplastic properties, such as polyethylene, polyvinyl acetate, polypropylene, or else with elastomeric properties, such as, for example, based on polyurethane, rubber, silicone. Natural adhesives, for example based on starch, are also 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 and 30 percent by weight, depending on the adhesive.
- binding fibers adhesives or a combination thereof can be used as binders.
- adhesives there is no need to add any adhesive to the wood fibers if the required binding is done 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 can consist of metals, for example aluminum, iron or the like. A mixture of different high-density substances can also be used.
- the high-density particles are preferably in small pieces.
- the particles of high density should penetrate into the soundproofing mat during manufacture and, if at all, should only come to a small part directly on the mat surface.
- the ideal diameter or the grain size spectrum depends on the natural raw material fibers used (wood fibers, natural fibers, binding fibers), the binding fibers used and / or the adhesive or mixture of adhesives used.
- the penetration behavior of the high-density particles in the mat can also be influenced by a grain size spectrum that is specifically coordinated with it or by the elongated or spherical geometry of the small-sized particles.
- quartz sand as a high-density material 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.
- the proportion by weight is in the range between 30 to 300 percent by weight based on the dry matter of the natural raw material fibers.
- the wood fibers and binding fibers are therefore combined in a first processing step into a, preferably homogeneous, mixture in the desired ratio and formed into a loose mat.
- the mat can be laid either mechanically or in the airlay process. The latter method is used inter alia. also used for the mat formation of non-woven mats and has also proven itself for the production of the mat according to the invention.
- the adhesive can be added during the manufacture of the mat.
- 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. If suitable adhesives are used, curing by the action of ionizing radiation (for example electron radiation) is also conceivable. 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 particles are sprinkled in. These are sprinkled on the mat surface and inserted into the depth of the mat, for example by shaking from the top. Excess particles remaining on the surface can, if necessary, be removed, for example by suction or other mechanisms. Then the mat is actually solidified by the action of heat and pressure.
- the temperature on the top of the mat will generally be between 100 and 200 ° C, on the underside of the mat usually below 100 ° C.
- the individual manufacturing steps can be carried out in immediate succession. However, it is also conceivable to carry out the individual production steps separately, in terms of time and location.
- the production of an endless mat up to the pressing is certainly desirable, but a cyclical production is also possible.
- the pressing can either take place cyclically 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 thus achieved on the one hand by the one-sided scattering of the high density substances.
- the unequal action of heat on the mat top and the mat underside even the inhomogeneous distribution of the high-density particles can be achieved.
- the natural raw material fibers in particular the wood fibers, can already be provided with an adhesive using the blow-line method during fiber production. Subsequent exposure to adhesives after fiber drying is also conceivable and can be done before or during the formation of the mat.
- a necessary application of adhesives in particular a gluing of the flax fibers, hemp fibers, sisal fibers, coconut fibers or fibers from other natural raw materials can also take place during the 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, to which fibers to be applied are applied.
- the adhesive can also be applied either to the wood fiber and / or to the binding fiber in the course of the mat formation.
- the overall task of the adhesive is to strengthen the fiber composite so that after the manufacturing process There is a defined thickness of the sound insulation mat and the high-density particles embedded in the fibers are fixed in such a way that the particles cannot detach from the mat during further processing and laying of the mat or during use.
- Fig. 2 is a graphical representation of the density profile of the soundproofing mat shown in Fig. 1.
- FIG. 1 shows a schematic representation of the structural structure of a sound insulation mat 2 according to the invention.
- 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 bottom 8.
- the floor covering (not shown) lies on the mat top 6 and the substructure of the floor (not shown) lies on the mat underside 8.
- the mat layer 4 essentially comprises natural raw material fibers 10, a binder 12 (not shown in a structured manner) and high-density particles 14 as components.
- the particles 14 are within the mat Tichticht 4 arranged inhomogeneously distributed and produce a density distribution increasing from the mat bottom 8 to the mat top 6. 1 shows that the frequency distribution of the occurrence of the particles 14 in the area of the mat top 6 is significantly greater than in the middle area of the mat layer 4 and than in the area of the mat underside 8. Otherwise the natural raw material fibers 10 and the binder 12 are arranged essentially homogeneously are 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 the impact sound insulation can be very well fulfilled.
- the mat is still selectively deformable to a certain extent, which helps to compensate 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.
- Example 1 The production of such an insulation mat is described in Example 1 below.
- 100 parts by weight of glue-free wood fibers are mixed homogeneously with 10 parts 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 approximately 1500 g / m 2 and a thickness of approximately 12 mm.
- Thickness-controlled driving style (target thickness 3 mm) A soundproofing mat with a thickness of approximately 3 mm is obtained, which is very flexible and has a density profile corresponding to FIG. 1. The entire surface of the mat, glued to the underside of a laminate flooring, effectively reduces the impact and ambient 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 pairs of calibration rollers.
- the result is an intermediate product with a weight per unit area of approx. 2500 g / m 2 .
- quartz sand is sprinkled in and the mat is compacted using 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 glue-free binding fibers based on cellulose fibers.
- an adhesive based on acrylate is applied to the wood fiber to the extent of approx. 10 parts by weight based on the wood mass.
- 100 parts by weight of the glued wood fibers are mixed homogeneously with 10 parts by weight of cellulose fibers and formed into a mat in the airlay process.
- the cellulose fibers have one Stack length of approx. 60 mm and have a fiber diameter of approx. 7 dtex.
- the mat is needled for consolidation.
- Thickness-controlled driving style target thickness 5 mm
- An insulating mat with a thickness of approximately 5 mm is obtained, which is very flexible and has a density profile similar to that of FIG.
- the entire surface of the mat on the underside of a laminate floorboard results in an effective subjective reduction of the impact and room noise level.
- Example 4 describes the production of a mat without the use of an adhesive.
- 30 parts by weight of hemp fibers (average length approx. 20mm) are mixed with 70 parts by weight wood fibers and 10 parts by weight of a binding fiber (cellulose fiber, length approx. 50mm, fiber diameter approx. 7 dtex) and a loose mat in the airlay process with a basis weight of 3000g / m 2 produced 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 shaken into the depth introduced the mat.
- 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 .
