Abstract: The oil swelling rubber (OSR) was prepared by home made resin modified styrene butadiene rubber,and reinforced by aramid fiber.The morphology,the rheological properties,the mechanical and oil absorption properties of rubber,as well as the reinforcement of the aramid fiber on OSR before and after oil absorption were studied.The results showed:with the increase of the amount of aramid fiber,the mechanical properties of OSR were improved,while the oil absorption performance was decreased.When the amount of fiber was 4 phr,the oil absorption rate of p-xylene and gasoline were 211.50% and 159.91% respectively,and the oil retention rate was 93.5% and 86.7% respectively.The tensile strength was 1.84MPa,the elongation at break was 63.18%,and the hardness reached 38.00MPa.The addition of resin and aramid fiber ensured that the absorbed oil-expanded styrene-butadiene rubber was not easily broken by external force.
