Abstract
A rubber composition having high adhesiveness to a metal, high modulus, high set resistance and high heat resistance, comprising raw material rubber, 2,4-dimercapto-6-substituted-1,3,5-triazine and a polymer having epoxy groups crosslinkable with the raw material rubber; a process for producing the rubber composition exhibiting adhesion stability, by controlling temperature of mixing step when crosslinking the rubber composition with an organic crosslinking agent; and a hose having excellent heat resistance and sufficient modulus and compression set resistance, wherein an inner tube and/or outer cover comprise the rubber composition and a reinforcing layer comprises brass-plated steel wires. Further, a compounding agent having good handling property comprising triallyl isocyanurate or the like supported on silica (solidified product), obtained by heat treating a mixture of triallyl isocyanurate or the like and silica, and a rubber composition having high modulus while maintaining high heat resistance, containing the same.
