Abstract

DC60 This invention provides carbon black. For functional rubber elements that can provide tires with very good exact resistance. And the performance of the UHF vulcanization process at high frequency induced by heat, carbon black has a surface area The topical bioavailability of nitrogen (N2SA) is 15 to 30 m 2 / g, and DBP bioavailability is 100 to 135 cm, 3/100 g and satisfactory is the correlation of formulas (1) and (2) as follows, (1 ) 460-10.5xN2SA Greater than or equal to Dst (2) 2900 is greater than H, where N2SA represents the specific surface area where nitrogen is absorbed. (2 meters / g), Dst represents the random diameter (nm) of the diameter distribution, the stokes of the combined carbon black, and H represents the amount of hydrogen. (Micrograms / g) per 1 gram of carbon black

All claims which will not appear on the advertisement page: Revised 30 Apr 2020 No claims -------------------------------------------------------------------------- ------28/02/2018------(OCR) Page 1 of 1 page Claims 1. Functional carbon black for rubber components with a specific surface area for nitrogen adsorption (N2SA) of 15 to 30 m2/g and DBP (Dibutyl phthalate) adsorption of 100 to 135 cm3/100g, which is characterized by the carbon black for rubber components that conforms to the relationship of formulas (1) and (2) as follows, (1) 460-10.5xN2SA > Dst (2) 2900 > H where N2SA represents the specific surface area for nitrogen adsorption. (m²/g), Dst represents the patterned diameter (nm) of the Stokes diameter distribution of the combined carbon black, and H represents the amount of hydrogen (mcg/g) per 1 gram of carbon black. The carbon black is produced in a cylindrical reaction furnace in which a tangentially circular air delivery channel (1) at the end, a small diameter drum-shaped combustion channel (6) (7) and a large diameter reaction channel (8) are arranged axially, a rapid cooling section (10) including instantaneous water cooling (9) in the water stream area and a leading vertical cooling pipe (11) in which the combustion channel (6) includes a primary combustion device 2 mounted axially to the furnace and a dual-structured inlet nozzle (5) which is created by an external cylindrical raw material furnace (3) with a coated surface. It is cooled by water and can be exchanged in the direction on the axis of the furnace and the nozzle that is forced into the cylindrical axis of the telescopic (4) attached to the external cylindrical raw material combustion device (3) and the nozzle that is forced into the cylindrical axis of the device (4) is properly expanded/compressed to adjust the position of the material intake into the device. 1. Carbon black for rubber compounds exhibiting specific nitrogen-absorbing surface area (N2SA) of 15 to 30 m²/g and DBP of 100 to 135 cm³/100g, and which are satisfied by the relationship of formulas (1) and (2) as follows, (1) 460-10.5xN2SA(formula)Dst(2)2900(formula)H where N2SA represents the specific nitrogen-absorbing surface area (m²/g), Dst represents the standard diameter (nm) of the distribution of the Stokes diameters of the combined carbon black, and H represents the amount of hydrogen (mcg/g) per 1g of carbon black.
