Definitions

  • the invention relates to a base, in particular a soundproofing device for floor coverings, in particular for laminate, veneer and / or wooden floors, with an element which is formed from a binder and fillers and can be connected to the back of the floor covering.
  • Floor coverings in particular wooden floors, have numerous advantages, they create a cozy feeling of comfort, are easy to maintain and have a long service life.
  • Wooden floors, in particular laminate and / or veneer floors, or the like from high-density fiber / chipboard. are produced and have a coating and / or a veneer at least on the upper side, but have the disadvantage that relatively loud noises are produced when they are walked on. The reason is that these floor elements are light and very stiff and hard because of their compact structure. If such floors are stimulated, especially when walking on hard heels, they generate a high sound level that propagates in the floors, ceilings and walls of a building and is transmitted to the air.
  • EP-0 864 712-A2 has already proposed sound-absorbing mats, which are glued to the entire surface on the underside of a laminate floor and made of a flexible, thermoplastic material with visco-elastic behavior, a thickness between 1 and 3 mm and one Density of at least 2 g / m 3 exist.
  • EVA ethylene / vinyl acetate copolymer
  • DE-298 20 016-U1 also proposes a soundproofing layer with a weight per unit area between 0.5 kg / m 2 and 10 kg / m 2 , which has a specific weight between 0.4 kg and is fixed over the entire surface with a floor board on the underside thereof / dm 3 and 1.5 kg / dm 3 and should consist of a composite material with rubber granules bound by polyurethane (PU).
  • PU polyurethane
  • the object of the invention is therefore to provide an inexpensive solution by which the excitation of such hard floor coverings is reduced to such an extent that the impact sound generated when walking on is not perceived as disturbing. Another task is to create a new, simple and inexpensive installation option without the need for a permanent bond to the substrate.
  • the element which can be connected or connected at least in regions to the back of the floor covering has a layer thickness of 1 to 6 mm and a weight of 0.8 to 2.80 kg / m according to the preamble of claim 1 2 per mm layer thickness depending on the chosen fillers and their grain sizes.
  • Such a soundproofing element is fundamentally inexpensive to produce, depending on the binders and fillers selected, and achieves sufficient impact sound insulation after the tests carried out by the applicant.
  • the floor covering With weights of 0.8 to 2.80 kg / m 2 per mm of layer thickness, there is sufficient sound absorption on the one hand to reduce the resulting impact sound by at least 3 to 5 dB even when stimulated by walking on hard coverings, on the other hand, the floor covering remains manageable, that is, it does not become so heavy that it can no longer be easily transported and relocated. On the other hand, it can be fixed with sufficient stability without additional gluing to the substrate.
  • the binder is polyurethane (PU).
  • PU polyurethane
  • Such a PU binder is quickly cured thermally and after passing through this kiln section and a cooling section can then be immediately wrapped as a covering.
  • the chemical start reaction is only permitted from certain furnace run-through temperatures. In both cases, the oven hardening starts a very fast hardening process, instead of a hardening reaction that would otherwise take days only at room temperature.
  • a PUR binder polyurethane base
  • no separate leveling agents or the like are required. more necessary, since the PU portion is specially matched to the flow properties in connection with the mineral filler grain distribution. Depending on the filler type and grain size selected, this PU content is between 5 and 45%.
  • the recipe for the production of the sheet goods with PU binders and mineral fillers is naturally very stable. Due to the high mineral content, there is no need to add fungicidal or biocidal additives to prevent the product from rotting.
  • the product produced in this way is completely emission-free, since it is produced without the addition of solvent and polyurethane reacts in the curing reaction shown according to the polyaddition mechanism, without Spin-off of by-products.
  • other stabilizers, such as antioxidants can also be dispensed with.
  • the binder is a compact or a foamed 2-component polyurethane (PU) or else a 1-component polyurethane formulation or a 1-component prepolymer formulation.
  • PU 2-component polyurethane
  • polyethylene PE
  • latex polyvinyl chloride
  • PVC polyvinyl chloride
  • Mineral fillers are provided as fillers, lime, chalk, glass, quartz powder, quartz sand, slag, ceramic particles, heavy spar (barium sulfate) are particularly advantageous. These materials can be sprinkled particularly well in a two-component polyurethane (PU). Depending on the choice of mineral aggregate and the associated particle size distribution, insulation elements with a density of 0.8 to 2.80 kg / m 2 per mm can be used Reach layer thickness. The same applies when using organic fillers, in particular corn flour and / or coconut shell granulate. The filler content can increase up to 98%. A two-component polyurethane binder with appropriate mineral or organic additives is particularly advantageous since the manufacturing process is very simple and, moreover, relatively little of the polyurethane binder has to be used. Depending on the choice of PU system used, the elastic properties and the associated damping properties of the element can be set from very hard / brittle to soft / highly elastic.
  • the soundproofing element can be designed both as a sheet material and as a partial element matched to one or more floor covering elements. When laying, it is therefore possible to first design a sound insulation device as a sheet and then only then lay the actual floor covering, in which case a firm connection between the floor covering and the sheet must then preferably be created so that sound absorption when the floor covering is excited by hard Shoe soles is reached.
  • the element is advantageously designed as a sub-element that is matched to one or more floor covering elements so that a firm connection, either at the factory or by the user, is made between the soundproofing element and the floor covering, ie the individual floor board or the individual laminate laying board, before installation.
  • This has the further advantage that a relatively heavy dimensionally stable installation product is created.
  • resulting changes in length, for example of laminate flooring elements, and the resulting tension due to alternating growth and / or shrinking tendencies can be absorbed by the horizontal deformability and the effective transverse forces in the sound insulation device designed as a base, so that it no longer leads to the known damage to the Laminate products, especially edge swellings or thickness growth in the edge area, comes.
  • the soundproofing element can be combined with a vapor-retardant layer to be applied on site to the laying substrate. This is particularly useful for screeds with a corresponding moisture content.
  • the binder in the soundproofing element is a polyurethane (PU) mixture with a recipe-related "adhesive tack".
  • the sound element acts like a slip brake on the old floor covering or screed underneath after it has been installed, thus preventing the sound insulation element from moving.
  • changes in length can be compensated and transverse and / or shear forces that occur can be absorbed.
  • the invention also provides that a fleece and / or a fabric is laminated onto the element on the underside and / or on the top, and a vapor barrier or barrier can also be laminated on the underside and / or on the top.
  • a fleece and / or fabric improves the visual appearance of the element and can improve its integrity, and it can also be used to conceal slight unevenness in the floor.
  • the fleece takes on the task of a positive, appealing surface appearance and thereby enables a lower requirement profile for the surface properties of the web material itself. This can save costs.
  • the fleece is visually appealing and can be printed, for example with product identifiers, brands, manufacturer's instructions, laying instructions, product arguments and the like. the like
  • the fleece and / or the vapor barrier / barrier can be adjusted to the respective specific requirements, for example as a gluing aid if the entire product is to be glued flat to the subfloor, or as a slip aid if the entire product is to be laid floating and not glued.
  • hot lamination processes with lamination foils or the like are used for the lamination of such materials. used. It is also possible to laminate the nonwoven fabric or the like with the aid of the recipe-related adhesive tack.
  • the invention also provides that the soundproofing element springs back on the edge relative to the respective floor covering element and / or has a chamfer. This avoids that when pushing and joining individual floor elements, for example in the case of elements equipped with tongue and groove, disabilities occur.
  • the invention also provides a floor covering that is provided on the back with a sound insulation device according to at least one of the configurations described above.
