Dispersion adhesives, a process for preparing them and use thereof |
| 摘要 |
The present claims relate to aqueous dispersion adhesives comprising at least one polyurethane dispersion and at least one carbodiimide having the general formula R′—(—N═C═N—R—)m—R″, in which m corresponds to an integer from 1 to 500, R=arylene and/or C7-C11 aralkylene, R′═R—NCO, and R″═—NCO, where in R′, independently of one another, R1 and R2 are identical or different and represent a C1-C6 alkyl, C6-C10 cycloalkyl or C7-C18 aralkyl radical. |

1. Aqueous dispersion adhesives comprising at least one polyurethane dispersion and at least one carbodiimide of the formulae (II), (III) and/or (IV) where R′″═C1-C18 alkylene, C5-C18 cycloalkylene, arylene and/or C7-C18 aralkylene and j within the molecule is identical or different and denotes 1 to 5, and p can be =0 to 500, where x=1 to 500. |
