Definitions
- the invention relates to a sealing mat at least partially filled with bentonite or another highly swellable clay with a carrier sheet and a cover sheet which is connected to the carrier sheet by means of seams.
- the powdered bentonite is embedded in a loose aero fleece, which is arranged between the carrier sheet and the cover sheet.
- the object of the invention is to provide a sealing mat of the type mentioned, in which the occurrence of shrinkage cracks is largely prevented and rinsing of such cracks is avoided.
- the carrier sheet is an elastic sheet made of foam plastic with a closed outer skin and open cells in which the bentonite is embedded and the open side of the cells is covered by the cover sheet: Because the bentonite in the only On one side open cells of the foam plastic are stored, on the one hand the complete drying out of the absorption Bentonite swollen by water and the cell walls and the closed outer skin of the foam plastic sheet prevent cracks from rinsing out in the bentonite layer, so that erosion of the sealing mat is not to be feared.
- the open-cell foam layer with the closed outer skin is preferably soft and elastic and has a leathery-tough outer skin.
- This foam web can be 3 to 10 mm thick and is sewn after filling with bentonite with a cover layer, which is preferably formed from a nonwoven fabric or a ribbon fabric.
- the seams which connect the carrier web to the cover web expediently run in the longitudinal direction and are at a distance of 20 to 50 mm from one another.
- the closed outer skin of the foam plastic sheet is reinforced by a textile reinforcement sheet which is sewn to the cover sheet together with the at least partially filled with bentonite foam sheet.
- the foam plastic sheet can also be glued to a textile reinforcement sheet before being filled with bentonite, or it can be connected in a flat manner in some other way. This can be done in that, for example, the foam plastic sheet is foamed onto the reinforcing sheet and is thus intimately connected to the reinforcing sheet with its closed outer skin.
- the foam plastic sheet with cells open on one side and a closed outer skin is advantageously produced from a foam plastic sheet twice as thick, which has a closed outer skin on both sides and which is severed along its central plane.
- integral or structural foams have a closed outer skin on both sides and an open-cell core, with the cell diameter decreasing from the center to the edge. If this foam layer is severed in its central plane, then the relatively large cells in particular are completely open, so that the foam plastic web can easily be attached Fill bentonite. The degree of filling can be increased by shaking or kneading the foam plastic layer.
- FIG. 2 shows a plan view of a sealing mat in which the closed outer skin of the foam plastic sheet is reinforced by a reinforcing sheet made of fabrics
- Fig. 3 shows a schematic representation of the production of open cells
- Foam plastic sheet with closed outer skin Foam plastic sheet with closed outer skin.
- the carrier web 1 consists of an elastic foam plastic web with a closed outer skin 4 and open cells 5, in which the bentonite is embedded, and a cover web 2, which is sewn onto the foam plastic web filled with bentonite.
- the seams 3 run in the longitudinal direction of the sealing mat and have a distance of 20 or 30 mm. So that the outer skin 4 can also absorb larger local loads, the foam plastic sheet and in particular the outer skin 4 is fiber-reinforced.
- Polyethylene, polypropylene or polyamide are particularly suitable as the material for the elastic foam plastic sheet 1.
- a textile reinforcement sheet 6 can be provided, which is sewn to the cover sheet 2 together with the foam plastic sheet 1 filled with bentonite.
- the seams 3 are designed such that the closed outer skin 4 or the reinforcement sheet 6 maintains a distance from the cover sheet 2 which corresponds approximately to the thickness of the foam plastic sheet 1.
- a foam plastic sheet 10 twice as thick is first produced, which has a closed outer skin on both sides. After this foam plastic sheet 10 has hardened, it is severed along its central plane 11. The cutting can be done by cutting, sawing or even with a hot wire or done by laser beams. The foam plastic sheets 1 can then be wound up and fed to further processing.
