Abstract
A method of bonding fabric to rubber in forming a composite having adhesive strength therebetween. The method includes pretreating the fabric by subjecting it to a solvent selected from the group consisting of isocyanate solvent, epoxy solvent, and liquid mixtures thereof, subjecting the pretreated fabric to a liquid containing acrylonitrile-butadiene-latex and a resorcinol-formalin mixture wherein the solid weight ratio of the acrylonitrile-butadiene-latex to the resorcinol-formalin is in the range of from approximately 10 to 1 to approximately 2 to 1, the mol ratio of resorcinol to formalin is in the range of from approximately 1 to 3 to approximately 3 to 1, and the acrylonitrile-butadiene-latex contains at least approximately 3% carboxyl groups, heat treating the fabric, and vulcanizing unvulcanized high temperature resistant hydronitrile rubber in association with said fabric. A rubber/fabric composite manufacture embodying the invention utilizing a rubber composite having an isocyanurate organic peroxide vulcanizing agent is disclosed.
