An aqueous polymer dispersion adhesive which comprises:A) 10 to 98% by weight of at least one aqueous dispersion of a (co)polymer comprising residues of at least styrene and optionally at least one member selected from the group consisting of alkyl acrylate and alkyl methacrylate containing 1 to 12 carbon atoms in the alkyl group, the solids content of the dispersion being in the range from 30 to 80% by weight; B) a thickener comprising a combination of a) 0.4 to 6% by weight, based on the weight of the adhesive, of an inorganic thickener, and b) 1 to 10% by weight, based on the weight of the adhesive, of an aqueous system comprising a polymer comprising residues of at least acrylic acid and acrylamide with a solids content of 10 to 40% by weight, wherein up to 90% by weight of the aqueous system being replaceable by at least one polymer dispersion selected from the group consisting of polymer dispersions containing acrylate residues, copolymer dispersions containing at least acrylic acid residues and methacrylic acid residues and polyurethanes the aqueous system having a solids content of 20 to 40% by weight; C) 0 to 88% by weight of fillers; D) 0to 2% by weight of pigments; E) 0 to 3% by weight of auxiliaries; F) 0 to 40% by weight of plasticizers; and G) water.
- 2. The adhesive as claimed in claim 1 comprising:A) 51 to 98% by weight of the styrene/acrylate (co) polymer dispersion; B) a) 1 to 3% by weight of highly disperse silica, c) 1 to 5% by weight of an acrylic acid/acrylamide copolymer w/o emulsion.
- 3. The adhesive as claimed in claim 1, having a pH value greater than 7.
- 4. The process for the production of the adhesive of claim 2 which comprises: forming a mixture of A) with the inorganic thickener and any of C) through G) to be included in the composition, and as a final step admixing the aqueous system of the copolymer comprising at least acrylic acid and acrylamide residues with the mixture.
- 5. The method of applying the adhesive of claim 2 wherein the adhesive is applied from a cartridge.
- 6. The method of claim 5 wherein the adhesive is applied to the substrate in a layer thickness of up to 30 mm.
- 7. The adhesive of claim 1 having a pH value in a range of 7-10.
- 8. The adhesive of claim 2 having a pH value of greater than 7.
- 9. The adhesive of claim 2 having a pH value in a range of 7-10.
- 10. The process for the production of the adhesive of claim 8 which comprises: forming a mixture of A) with the inorganic thickener and any of C) through G) to be included in the composition, and as a final step admixing the aqueous system of the copolymer comprising at least acrylic acid and acrylamide residues with the mixture.
- 11. The method for applying the adhesive of claim 2 wherein the adhesive is applied from a cartridge.
- 12. The method for applying the adhesive of claim 3 wherein the adhesive is applied from a cartridge.
- 13. The method of claim 11 wherein the adhesive is applied to the substrate in a layer thickness of up to 30 mm.
- 14. The method of claim 12 wherein the adhesive is applied to the substrate in a layer thickness of up to 30 mm.
- 15. The adhesive of claim 1 wherein the (co)polymer of styrene contains 30% to 100% by weight of styrene residues.
- 16. The adhesive of claim 2 wherein the (co)polymer of styrene contain from 30% to 100% by weight of styrene residues.
- 17. The adhesive of claim 3 wherein the (co)polymer of styrene contains from 30% to 100% by weight of styrene residues.
