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 Vibration damping used in various technical industrial sectors, where the sealing elements usually made in the form of bands or moldings become.
- so-called open-celled foams which have a relatively high air permeability
- So-called closed-cell foams are also known have a low air permeability.
- For sealing in the construction industry will be impregnated flexible foams in the context of DIN 18542 in different stress groups divided.
- sealing elements are known from FR 1 544 724, for example DE 1 000 946, EP 317 833 A2 and EP 688 382 B1.
- the present invention is therefore based on the object, a sealing element soft foam, which is easy for use to seal joints is manageable and even with almost fully restored state extremely good sealing values achieved and complies with the relevant DIN standards.
- the sealing element is made of a soft 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 after compression delayed recovery to about 80-95% of its original thickness, thereby it is ensured that the desired standards are met even in the final state.
- the sealing element is preferably designed such that it performs a reliable reset from -10 ° C.
- the sealing element is flame-retardant, whereby the DIN ISO EN 4102 B1 with regard to the fire behavior also in the recovered Condition is fulfilled.
- the sealing element UV-resistant is.
- the sealing element according to the invention consists of a soft, flexible foam, preferably of a polyurethane foam. Likewise, however, the use of a melamine resin foam or a silicone foam is conceivable, for example.
- 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 more closed-cell the foam is, the more and the smaller cells it has.
- 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 dimensions Inlet and outlet cross sections as an open-pored foam and is therefore only in extreme limited permeable to air. This will ensure that the DIN standard 18542 BG1 with regard to driving rain already at about 90% of the original Thickness deferred foam is met, while previous soft foams at least 60% of the original thickness had to be compressed to the same Deliver values.
- the impregnate has UV-resistant substances that enhance the aging process slow down the foam and make it more resistant to direct sunlight do. It is also advantageous that the impregnate contains flame retardant, so that also the DIN ISO EN 4102 B1 regarding the fire behavior is fulfilled. Others too DIN standards regarding temperature stability, compatibility with other building materials etc. can be fulfilled by the present sealing element.
- the sealing element according to the invention is therefore ideal for use in the application as a joint sealing tape, flat gasket, molding, etc. and can both for Waterproofing against water, moisture, air and sound, for thermal decoupling and used for vibration insulation. Particularly preferred is the sealing of Movement joints in the interior and exterior.
- the sealing element according to the invention can also with be equipped one or more self-adhesive layers.
- the sealing element can also be used as pre-compressed roll goods getting produced.
- a sealing element is provided, compared to the previously known sealing elements provides significant benefits, is flexible and especially the requirements in the construction sector is excellently adjusted.
