Definitions

  • the invention relates to a sealing element made of soft, flexible foam.
  • sealing elements have already become known in various embodiments and are used to seal against water, moisture, air and sound or for vibration damping in various technical industrial areas, the sealing elements are usually made in the form of ribbons or moldings.
  • so-called open-cell foams which have a relatively high air permeability
  • so-called closed-cell foams which have a low air permeability.
  • impregnated flexible foams are divided into different stress groups within the scope of DIN 18542.
  • sealing elements are approximately from the FR 1 544 724 , of the DE 1 000 946 , of the EP 317 833 A2 .
  • a disadvantage of the previous sealing elements was that certain requirements such as driving rain tightness either only with strong compression of the sealing elements were fulfilled or that the sealing elements were difficult to handle.
  • the present invention is therefore an object of the invention to provide a sealing element made of soft foam, which is easy to handle for use in sealing joints and also achieved in almost fully restored state extremely good sealing values and meets the relevant DIN standards.
  • the sealing element is made of a soft polyurethane foam with an air permeability of at most 50 l / m 2 s and is designed such that, after compression, it undergoes a homogeneous, delayed recovery over substantially its entire length and width. This ensures that the sealing element is versatile and flexible in use and even in almost fully recovered state has an enormously high driving rain.
  • the sealing element is designed such that it performs a delayed recovery to about 80-95% of the original thickness after compression, thereby ensuring that even in the final state, the desired standards are met.
  • the sealing element is preferably designed such that it performs a reliable reset from -10 ° C.
  • the sealing element is formed flame-retardant, whereby the DIN ISO EN 4102 B1 is met in terms of fire behavior even in the recovered state.
  • the sealing element is UV-resistant.
  • the sealing element according to the invention consists of a soft, flexible polyurethane foam.
  • the sealing element according to the invention has a net-like skeleton in which a dense cell skeleton is implemented.
  • the foam is designed as a closed-cell foam, which has an air permeability of at most 50 l / m 2 s (measured according to DIN 53887 with a so-called Frank device), preferably at most 40 l / m 2 s, more preferably at most 25 l / m 2 s having.
  • the air permeability is therefore also correlated with the number and size of the cells.
  • an air permeability of 40 l / m 2 s corresponds approximately to a cell density of 25 ppi (pores per inch) and a cell diameter of 700 ⁇ m. "Pors per inch" is a common indication of the amount of cells contained in a foam.
  • the sealing element is impregnated with a suitable impregnate, preferably by introducing the sealing element into a dipping bath and subsequent rolling, and then dried, preferably heat-dried.
  • the impregnate here preferably has a viscosity of at most 500 mPas, more preferably at most 400 mPas, at 20 revolutions per minute (determined with a Brookfield Rheometer) and a solids content of at most 40% (determined with a Sartorius drier), preferably at most 30%, on.
  • the particle size of the solids is not more than 0.1 mm.
  • the impregnate based on an aqueous binder solution preferably an acrylate solution, hydrophilic and hydrophobic components are added, and it is already achieved with a impregnating weight of less than 20 kg / m 3 dry mass homogeneous impregnation.
  • aqueous binder solution preferably an acrylate solution, hydrophilic and hydrophobic components
  • hydrophilic and hydrophobic components are added, and it is already achieved with a impregnating weight of less than 20 kg / m 3 dry mass homogeneous impregnation.
  • the impregnation not only an external wetting of the cell walls, but a penetration of the almost closed cell membranes, so that an internal wetting is achieved with the impregnation medium.
  • the sealing element of the invention may for example have a density of about 80 kg / m 3 and is delayed after compression over its entire length and width back until it has expanded again to 80-95%, preferably about 90% of the original thickness.
  • the reset properties are also dependent on ambient conditions such as temperature, humidity and storage time. It is particularly important here that the provision of substantially uniform over the entire length and width of the sealing element, which is ensured by the homogeneous impregnation of the sealing element. Due to the homogeneous delayed reset, a flexible use, eg as a joint sealing tape, is guaranteed. After compression of a provision of the sealing element according to the invention is already guaranteed from a material temperature of -10 ° C.
  • the closed-cell foam used here has smaller inlet and outlet cross-sections than an open-pore foam and is therefore permeable to air only to a very limited extent. This ensures that the DIN 18542 BG1 standard regarding watertightness is already met with a foam restored to approximately 90% of the original thickness, whereas previous soft foams had to be compressed to at least 60% of the original thickness in order to provide the same values.
  • the impregnate has UV-resistant substances that slow down the aging process of the foam and make it more resistant to direct sunlight.
  • the impregnate contains flame retardant, so that the DIN ISO EN 4102 B1 is met with respect to the fire behavior.
  • Other DIN standards with regard to temperature stability, compatibility with other building materials, etc. can be met by the present sealing element.
  • the sealing element according to the invention is therefore ideal for use in the application as a joint sealing strip, flat gasket, molded part, etc. and can be used both for sealing against water, moisture, air and sound, for thermal decoupling and vibration insulation. Particularly preferred is the sealing of Bewegüngsfugen indoor and outdoor.
  • the sealing element according to the invention can also be equipped with one or more self-adhesive layers.
  • the sealing element can also be produced as pre-compressed roll goods.
  • a sealing element which provides significant advantages over the previously known sealing elements, is flexible in use and is particularly well adapted to the requirements in the construction sector.
