Process for the elastic bonding of two substrate surfaces

Abstract Two substrate surfaces, at least one of which is porous, axe bonded with aqueous dispersions of adhesive. A rubber-containing first dispersion containing an acrylic acid ester polymer and a colloidal second disper-sion of a chloroprene polymer are applied to at least one of the substrate surfaces after prior or with simul-taneous thorough mixing. Immediately thereafter or somewhat later, the substrate surfaces to be bonded are placed on top of one another with adhesive emulsion in the wet state and pressed together. The two substrate surfaces adhere to one another with a high initial force. The water evaporates through the porous substrate surface(s). The process can be used particularly advantageously for the bonding of foams.

Process for preparing an aqueous undertread adhesive composition

A process for preparing an aqueous adhesive composition which comprises preparing a solvent dispersion by mixing rubber, carbon black, vulcanizing agent, tackifying resin and accelerator with sufficient organic solvent to form a solvent dispersion and thereafter emulsifying the solvent dispersion in the presence of water to form an aqueous emulsion. The aqueous emulsion may be used to bond unvulcanized rubber compounds, such as a tread stock to the carcass portion during the formation of a tire.
