Abstract

PURPOSE:A rubber composition having a high resilience and high hardness and tensile strength as well, containing furnace carbon black having specified selected properties. CONSTITUTION:Use is made of furnace carbon black having an electron-microscopic mean particle diameter (dn)>=31mmu, an iodine adsorption of 40-60mg/ g, a DBP absorption >=170ml/100g and a tinting strength >=131%. Namely, 100pts.wt. rubber component is mixed with 25-250pts.wt. above furnace carbon black. The effect is more marked especially when a synthetic rubber such as styrene/butadiene, ethylene/propylene, or polybutadiene rubber is used as the rubber component.

The present invention relates to a rubber composition blended with furnace carbon black having selective properties, which combines high impact repulsion with relatively high levels of hardness and tensile strength. The applicant confirmed the fact that the appearance interaction of the rubber component and the coupon black blended therein depends on the coloring power, which is a characteristic element other than the particle size and strafia, and the (gate) 31 mμ or more, iodine adsorption amount 4
0~6Qri/P, DBP oil absorption 90'-'13'Om
By adding the selective property of tinting strength of 175 or more to soft carbon black in the low waste heat imparting region of Q/100 f, we are developing a rubber composition that simultaneously has low heat build-up and high reinforcing performance. Success (Patent No. 1012175, Japanese Patent Publication No. 54'-'13461') L. The technology of the prior application allows the rubber component to have both high impact resilience and high reinforcing properties, which were conventionally achieved by controlling only the particle size and strafia of the blended carbon black. It has an excellent medicinal effect, but it is especially hard □
Because of the insufficiency in increasing the stiffness, tensile stress, and tensile strength, these materials have not been able to provide sufficient satisfaction for rubber applications that require these stiffness properties. □ ``The present invention is the result of multifaceted research with the aim of revising the above point; while maintaining high rebound elasticity L4, it has an even higher rebound than the prior art. The present invention proposes a rubber composition having a hardness of □ and □ tensile strength.

A carbon blank V having the above characteristics, a combustion chamber with a directional air supply port not in contact with the head, a combustion burner inserted in the axial direction of the furnace, and a raw material injection nozzle is connected to a wide diameter through a narrow diameter aperture. It is produced by a method in which feedstock oil is rapidly atomized and injected into the upstream region of a narrow diameter constriction section using a stepped cylindrical oil furnace connected to the rear chamber of 1.

These are essential requirements for obtaining carbon black that satisfies the characteristic items of 70 mQ/I OOt or more and tinting strength of 131% or more. . In addition, conditions such as the ratio of the total amount of air supplied to the total amount of feedstock oil and fuel oil introduced, the combustion rate of natural oil, and the flow rate of combustion gas at the feedstock introduction position are adjusted as appropriate, and the generated gas flow remains in the furnace. 200-280 hours
Carbon black having all the properties specified in the present invention is produced by controlling the temperature within the millisecond range.

I decided. The rubber composition according to the present invention (f(un slow 1~'() is city, i, microscopically sharp, average particle diameter (dn), and ↓) □hfyj: ItfJ, etc. level K
Compared to the soft carbon silicon compound rubber sold by Huru 71 (conventional example Run Nu 7 + 8), the LK hard IIj and pull sheet 1 (Su'ji!
Reinforcements such as I, modulus, etc. have ablated, and L (Improvement 3) is noticeable as F value. On the other hand, in the comparative example Run Nα4, the coloring power of the applied carbon black satisfies the minimum requirements of the present invention and the tensile strength cannot be increased, and in the same Run Nχ5, the DBP oil absorption is 170 mff1/
Since it is less than 100 da, no improvement effect is observed in both hardness and tensile strength. Comparative example Run N116 is a rubber composition according to the prior art (Patent No. 1032175), which has high impact resilience and relatively high reinforcing performance, but in the present example, hardness and tensile strength are In this way, we have taken this to an even higher level.
