TH75865B - Carbon black for functional rubber elements. - Google Patents

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

Carbon black for functional rubber components with a specific surface area of nitrogen absorption (N2SA) of 15 to 30 m2/g and absorption of DBP (Dibutyl phthalate (chibutyl phthalate) is 100 to 135 cm3/100 g, characterized by that carbon black for The functional rubber components conform 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 absorbed nitrogen. (m2/g), Dst represents the patterned diameter (nm) of the diameter distribution of the stokes of the combined carbon black, and H represents the amount of hydrogen. Carbon black is produced by cylindrical reaction furnaces in which circular tangent air channels (1) at the tip, channels. The combustion chamber (6), one drum-shaped part of small diameter (7) and the reaction cavity. of large diameter (8) prepared with a common core, rapid cooling (10) including instantaneous cooled by water (9) at the tidal area and pipes. Heat dissipation (11) leading straight vertically where the combustion chamber (6) includes primary combustion apparatus 2 trapped in the direction on the axis of the furnace and the nozzles being injected into the apparatus (5) with a structure that in pairs which is formed by an external cylindrical raw material furnace (3) in which the glaze is made. cool with water and can be exchanged in the direction that is on the axis of the furnace and the nozzles that are fed into The cylindrical machine that forms the axis of the telescopic (4) is attached to the raw material combustion device. The external cylindrical nozzle (3) and the nozzles injected into the cylindrical axis (4) are properly expanded/compressed. to adjust the position of the import of the substance that is fed into the machine ------------ 1. Carbon black, for the tire composition showing a specific surface area, nitrogen absorption (N2SA) is 15 to 30 m2/g and DBP absorption is 100 to 135 cm3/100 g, and satisfactorily will be The relationship of formulas (1) and (2) is as follows, (1) 460-10.5xN2SA (formula) Dst, (2) 2900(formula)H, where N2SA represents the nitrogen-absorbed specific surface area. (m2/g), Dst represents the conventional 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
