Abstract
A rubber composition containing 20 parts by weight-200 parts by weight of hydrogenated styrene thermoplastic elastomer and poly-olefin for 100 parts by weight of rubber which is dynamically vulcanized with a resin vulcanizing agent to disperse the rubber in a mixture of the hydrogenated styrene thermoplastic elastomer and the poly-olefin.
Claims15
A rubber composition containing 20 parts by weight-200 parts by weight of hydrogenated styrene thermoplastic elastomer and poly-olefin for 100 parts by weight of rubber, wherein said rubber is dynamically vulcanized with a resin vulcanizing agent to disperse in a mixture of said hydrogenated styrene thermoplastic elastomer and said poly-olefin, and wherein the friction coefficient of the hydrogenated styrene thermoplastic elastomer is 1.6-1.9.
A rubber composition containing 20 parts by weight-300 parts by weight of hydrogenated styrene thermoplastic elastomer, poly-olefin, and softener for 100 parts by weight of rubber, wherein said softener is 10 parts by weight-200 parts by weight for 100 parts by weight of said rubber, and said rubber is dynamically vulcanized with a resin vulcanizing agent to disperse in a mixture of said hydrogenated styrene thermoplastic elastomer, said poly-olefin and said softener, and wherein the friction coefficient of the hydrogenated styrene thermoplastic elastomer is 1.6-1.9.
A method of manufacturing a rubber composition containing 20 parts by weight-300 parts by weight of hydrogenated styrene thermoplastic elastomer, poly-olefin, and softener for 100 parts by weight of rubber, wherein the softener is 10 parts by weight-200 parts by weight for 100 parts by weight of said rubber, said method comprising the steps of:
- preparing a kneaded material of said hydrogenated styrene thermoplastic elastomer, said poly-olefin, and said softener;
- kneading and heating said kneaded material, said rubber, and resin vulcanizing agent so that said rubber is dynamically vulcanized to disperse fine particles of said vulcanized rubber in said kneaded material of said hydrogenated styrene thermoplastic elastomer, said poly-olefin, and said softener.
