Definitions
- the invention relates to a sealing element made of soft, flexible foam.
- sealing elements are already known in various configurations and are used for sealing against water, moisture, air and sound or for vibration damping in a wide variety of technical industrial areas, the sealing elements usually being produced in the form of strips or molded parts.
- so-called open-cell foams which have a relatively high air permeability
- so-called closed-cell foams are also known, which have a low air permeability.
- soaked soft foams are divided into various stress groups within the scope of DIN 18542.
- sealing elements are known, for example, from FR 1 544 724, DE 1 000 946, EP 317 833 A2 and EP 688 382 B1.
- the present invention is therefore based on the object of providing a sealing element made of soft foam which is easy to handle for use in sealing joints and which achieves extremely good sealing values even when it is almost completely restored and meets the relevant DIN standards.
- the sealing element consists of a soft foam with an air permeability of at most 50 l / m 2 s and is designed in such a way that after compression it performs a delay which is homogeneous, essentially homogeneous over its entire length and width. This ensures that the sealing element is versatile and flexible in use and has an extremely high level of driving rain tightness even when it is almost completely reset.
- the sealing element is preferably designed in such a way that, after compression, it is delayed to about 80-95% of the original thickness, which ensures that the desired standards are also met in the final state.
- the sealing element is preferably designed in such a way that it performs a reliable reset from -10 ° C.
- the sealing element is designed to be flame-retardant, as a result of which the DIN ISO EN 4102 B1 is also fulfilled in the reset state with regard to fire behavior.
- the sealing element is UV-resistant.
- the sealing element according to the invention consists of a soft, flexible foam, preferably of a polyurethane foam. However, it is also conceivable, for example, to use a melamine resin foam or a silicone foam.
- the sealing element according to the invention has a network-shaped basic structure, in which a dense cell structure is implemented.
- the foam is designed as a closed-cell foam that 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 an immersion bath and then rolling, and then dried, preferably heat-dried.
- the impregnate preferably has a viscosity of at most 500 mPas, more preferably at most 400 mPas 20 revolutions per minute (determined with a Brookfield rheometer) and a solids content of at most 40% (determined with a Sartorius dry measuring device), preferably at most 30%.
- the particle size of the solids is a maximum of 0.1 mm.
- Hydrophilic and hydrophobic components based on an aqueous binder solution preferably an acrylate solution
- Hydrophilic and hydrophobic components based on an aqueous binder solution are preferably added to the impregnate, and homogeneous impregnation is achieved with an impregnation weight of less than 20 kg / m 3 dry matter.
- an impregnation weight of less than 20 kg / m 3 dry matter.
- the sealing element according to the invention can, for example, have a density of approximately 80 kg / m 3 and, after compression, is delayed over its entire length and width until it has expanded again to 80-95%, preferably approximately 90% of the original thickness.
- the reset properties also depend on environmental conditions such as temperature, humidity and storage time. It is particularly important here that the provision is essentially homogeneous over the entire length and width of the sealing element, which is ensured by the homogeneous impregnation of the sealing element.
- the homogeneous delayed reset ensures flexible use, for example as a joint sealing tape. After compression, a resetting of the sealing element according to the invention is reliably ensured from a material temperature of -10 ° C.
- the closed-cell foam used here has smaller inlet and outlet cross-sections than an open-cell foam and is therefore only extremely permeable to air. This ensures that the DIN standard 18542 BG1 with regard to watertightness is already fulfilled with a foam that has been restored to approx. 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 preferably has UV-resistant substances which slow down the aging process of the foam and make it more resistant to direct sunlight. It is also advantageous that the impregnate contains flame retardants so that DIN ISO EN 4102 B1 is also fulfilled with regard to fire behavior. Other DIN standards regarding temperature stability, compatibility with other building materials, etc. can also be met with this sealing element.
- the sealing element according to the invention is thus outstandingly suitable for use as a joint sealing tape, flat gasket, molded part etc. and can be used both for sealing against water, moisture, air and sound, for thermal decoupling and for vibration insulation. The sealing of movement joints in the interior and exterior is particularly preferred.
- the sealing element according to the invention can also be equipped with one or more self-adhesive layers.
- the sealing element can also be manufactured as pre-compressed roll goods.
- a combination (e.g. by means of gluing or lamination) of this material with other materials is also conceivable, e.g. with any kind of open-cell and closed-cell soft foams (PE, PVC, cellular rubber, cellular rubber, PU) or with various foils, nonwovens etc. (such as PP, PE, PVC) that are already laminated onto standard foams.
- PE open-cell and closed-cell soft foams
- PVC cellular rubber
- cellular rubber cellular rubber
- PU various foils, nonwovens etc.
- Possible areas of application for the sealing elements according to the invention are, above all, expansion joints in the construction industry, joints between components in the motor vehicle sector and other industrial applications, such as Refrigerated counters, control cabinets etc.
- the area of application of the invention is very universal and is not limited to this.
