Abstract
Official abstract text for this publication.
The present invention is directed to a rubber composition comprising a diene based elastomer comprising a functional group selected from the group consisting of hydroxyl, primary amine, and secondary amine; and a binding agent selected from the group consisting of water-dispersible resin, polyelectrolytes, and polypeptides. The invention is further directed to a pneumatic tire including the rubber composition, and a method of increasing the green strength in a rubber composition.
First claim
Opening claim text (preview).
What is claimed is: 1 - 11 . (canceled) 12 . A method of increasing the green strength of a rubber composition, comprising the steps of: mixing a diene based elastomer latex with an aqueous dispersion of a binding agent selected from the group consisting of water-dispersible resin, polyelectrolytes, and polypeptides, to form a mixture comprising solids and liquid, wherein the diene based elastomer comprises a functional group selected from the group consisting of hydroxyl, primary amine, and secondary amine; and separating the solids from the liquid to obtain a solid composite. 13 . The method of claim 12 , where the diene based elastomer is selected from synthetic polyisoprene, natural polyisoprene, and polybutadiene. 14 . The method of claim 12 , wherein the diene based elastomer is a hydroxyl functionalized polyisoprene. 15 . The method of claim 12 , wherein the binding agent is a water-dispersible resin selected from the group consisting of resorcinol-formaldehyde resins and resorcinolmelamine resins. 16 . The method of claim 15 , wherein the water-dispersible resin is a resorcinol formaldehyde resin. 17 . The method of claim 14 , wherein the hydroxyl-functionalized polyisoprene has a number average molecular weight ranging from 50000 to 2000000. 18 . The method of claim 14 , wherein the hydroxyl-functionalized polyisoprene is derived from a synthetic polyisoprene or a natural polyisoprene. 19 . The method of claim 14 , wherein the weight ratio of the water-dispersible resin to elastomer ranges from 0.005 to 0.2. 20 . The method of claim 14 , wherein the hydroxyl-functionalized polyisoprene is a guayule rubber.
