Definitions
- This invention relates to a coated sheet-like structure, comprising a coating carrier, a base or base layer made of a plastic mass applied thereon and a further, second layer provided thereon.
- This invention further relates to a method for producing such a flat structure and a particularly favorable use for this flat structure.
- a sheet with a single coating is known from US-A-4 602 057.
- This single coating consists of copolyamide and 0.3 to 15% by weight of behenic acid.
- a uniform mixture of behenic acid and copolyamide is produced; This is followed by a temperature treatment above the melting temperature of behenic acid, but below the melting temperature of copolyamide, whereby an even loading is achieved. The required amount of coating can be reduced by this individual coating.
- Flat structures are also known which are provided with a base layer made of a plastic mass, which is preferably applied in the form of an aqueous paste to the flat structure in the form of a grid.
- the fabric is then vibrated with a rapidly rotating beater roller.
- a hot melt adhesive powder is sprinkled on the paste print.
- the excess powder not adhering to this base layer is blown off and suctioned off, and the paste of the base layer with the powder adhering to it is then dried and sintered.
- the coating grid which is preferably in the form of a dot, thus consists of a base layer made of this dried and sintered paste.
- the sintered hot-melt adhesive powder represents the further plastic layer sitting on it.
- the coated fabrics are laminated in sheets or as blanks with other sheets or cut sheets under the action of pressure and comparatively mild temperature to form composites with particularly high resistance to washing and cleaning.
- DE-B-22 31 723 describes such flat structures which have two layers lying one above the other.
- a base layer is used which, after drying and sintering, has a higher melting point and a higher melt viscosity than the hot-melt adhesive layer scattered thereon.
- Double-layer coatings of this type result in improved adhesion, a softer grip and a reduced tendency to kickback when fixing, so that they are increasingly able to assert themselves over single coatings.
- copolyamides, copolyesters, low-pressure polyethylenes and polyurethanes are used as plastic masses for the base layer.
- Copolyamides and copolyesters are particularly suitable as materials for the hot-melt adhesive layer.
- suspending or dispersing agents are used, which are also used in single coatings, for example combinations of fatty acids, ammonia and water-soluble thickening agents.
- Suitable dispersants are, for example, in the publications DE-B-20 07 971, DE-B-22 29 308, DE-B-24 07 505, DE-B-25 07 504, EP-A-0 150 262 and DE-B -35 10 109.
- This invention is therefore based on the object of providing a flat structure of the type mentioned at the outset which does not have the disadvantages listed above.
- the tendency to penetrate into the carrier should be reduced to the required minimum and, when using hot-melt adhesive powder as the second layer, the tendency to suck should be reduced without the adhesive strength of the base layer to the carrier and the hot-melt adhesive scattering coating to the base layer suffering.
- the duration of exposure to temperature should ensure, even with the short throughput times customary in coating technology, that the base layer and the hot-melt adhesive sprinkling coating sitting thereon are anchored fully cleanable and washable.
- a coated sheet which has a coating carrier, a base layer applied thereon and a further layer provided thereon, the base layer which is no longer flowable under the action of temperature being applied in a grid pattern, at least partially crosslinked, and an aliphatic carboxylic acid with a carboxyl group and at least 18 Contains carbon atoms per molecule in an amount of 2 to 10% by weight and optionally salts of divalent or trivalent metals of this carboxylic acid in an amount of 0.1 to 2% by weight, the amounts given relating to the dry weight of the base layer.
- the at least partial crosslinking should extend to such an extent that the base layer does not flow at all temperatures to which the coated fabric is exposed in later laminations with other fabrics.
- this aliphatic carboxylic acid in a Amount of preferably 2 to 8 wt.%, Particularly preferably 4 to 7 wt.%, Based on the dry substance, is contained.
