困難である。[Detailed Description of the Invention] In recent years, rubber materials such as those used in automobile tires have been required to have a high level of reinforcing performance (tensile strength, modulus, etc.) and dynamic performance (low light/thermal resistance, high rebound resilience, etc.). There is an increasing demand for simultaneous provision of these properties, but since these two properties are essentially contradictory, it is difficult to satisfy this demand from the viewpoint of rubber components.

The selective property with a Q measurement value of 120 or more contributes to the KTj effect of increasing both reinforcement and dynamic performance of the compounded rubber due to its unique effect based on its high surface activity, and it eliminates the dynamic performance regression phenomenon in the prior art. It serves the function of sufficiently supplementing the reinforcement performance and maintaining the reinforcing performance at a high level. Therefore, it is possible to expand the lower limit of the prime quantity to 25 q/li, which is equivalent to G PF (N660) class carbon black, so that it becomes a prerequisite characteristic, and dynamic performance can be improved from this aspect as well.

付与される。Carbon black having the characteristic requirements of the present invention has a combustion chamber equipped with a tangential air supply port in the furnace head, a combustion burner inserted in the axial direction of the furnace, and a convergent nozzle with a raw oil injection nozzle on the downstream side. It is produced in an oil furnace having a structure in which the reaction zone is converged and connected in a relatively short narrow diameter section, and the reaction zone is formed into a tapered shape that gradually widens from the narrow diameter section. Raw material oil such as creosote oil or ethylene bottom oil is ejected into high-temperature combustion gas flowing at high speed through a narrow diameter portion through a raw material oil injection nozzle. At this time, by controlling conditions such as the supply ratio of the total amount of air supplied to the total amount of raw material oil and fuel oil, the combustion rate of fuel oil, the initial jetting speed of raw material oil, and the flow rate of combustion gas, the prerequisite electron microscope average Particle diameter (dn) 3'1 mμ or more, iodine number 25-60q

The blending ratio of carbon blank is 25 to 250 parts by weight, preferably 40 to 80 parts by weight, per 100 parts by weight of the rubber component.
It is added and kneaded together with necessary components such as commonly used vulcanizing agents, vulcanization accelerators, anti-aging agents, vulcanization aids, softeners, plasticizers, etc. in parts by weight. During compounding, the Mooney viscosity of the composition is always kept low, and kneading and extrusion processes such as cross-crossing, extrusion, and molding proceed extremely smoothly.
