Abstract
An aqueous binder dispersion for use in the production of composite bodies by vulcanizing a vulcanizable rubber composition on a substrate which is stable under vulcanization conditions comprising water and at least one emulsifier and a solids content of from 20% to 50% by weight of a solids composition of, PA0 (a) per 1000 parts by weight of a polymer selected from the group consisting of polyvinylidene chloride, vinylidene chloride/alkyl acrylate copolymers, butadiene/acrylonitrile copolymers and mixtures thereof, PA0 (b) from 100 to 500 parts by weight of at least one aromatic poly-C-nitroso compound, PA0 (c) from 50 to 300 parts by weight of masked polyfunctional isocyanates, PA0 (d) from 20 to 100 parts by weight of a water-soluble polymer selected from the group consisting of polyvinyl pyrrolidone and water-soluble copolymers of vinyl pyrrolidone, and PA0 (e) from 5 to 500 parts by weight of customary fillers and pigments, adhesion-improving resins based on formaldehyde condensation products, adhesion-improving condensation products based on epichlorohydrin condensation products; emulsifiers and antifoam agents; as well as the method of bonding rubbers to solid substrates emp…
