Abstract

The present invention provides adhesives, aqueous resorcinol-formaldehyde-latex dispersions, fibers with improved adhesion, methods for their production and uses thereof. In particular to novel carbodiimide-based binders, to aqueous resorcinol-formaldehyde-latex dispersions comprising binders, to fibers with improved adhesion, to a method for producing them, and It relates to their use for improving adhesion in tires. The adhesive according to the invention comprises at least one carbodiimide based on a compound of formula (I): R'-(-N=C=N-R-)m-R"(I), where m is from An integer from 1 to 500, R=C1-C18-alkylene, C5-C18-cycloalkylene, arylene and / or C7-C18-arylalkylene, R'=R-NCO, R -NHCONHR1, R-NHCONR1R2 or R-NHCOOR3, and R"=-NCO, -NHCONHR1, -NHCONR1R2 or -NHCOOR3, wherein these compounds have been surface deactivated by reaction with at least one amine.

Description

technical field [0001] The present invention relates to new adhesives based on carbodiimides, to aqueous resorcinol-formaldehyde-latex dispersions comprising adhesives, to fibers with improved adhesion, to methods for producing them, and to them Use for improving adhesion in tires. Background technique [0002] Carbodiimides are often used to treat tire cords, see US-A-3867181 and DE-A-1770495. The treatment is performed to improve the hydrolysis resistance of PET fibers. DE-A-2326540 describes polyisocyanates comprising polycarbodiimides. However, these methods are based on undesired organic solvents and are uneconomical. [0003] In the tire industry, resorcinol-formaldehyde-latex-dispersions (RFL impregnates) have been particularly well established because they improve the adhesion of synthetic fabrics (cords) to rubber. [0004] However, one disadvantage when polyester is used as cord material is that the tackifying properties of RFL dips are insufficient. [0005] ...
