Patent ID: 10208137

Abstract:
A first tire member manufacturing method includes an operation in which a pre-coagulation rubber latex containing carbon black, for which a ratio of specific surface area as determined by nitrogen adsorption N2SA (in units of m2/g) to an amount of iodine absorption IA (in units of mg/g) is not less than 1.00, is coagulated to obtain a coagulum; an operation in which a compound according to Formula (I), below, is added to the water-containing coagulum; and an operation in which the compound according to Formula (I), below, is dispersed within the coagulum.In Formula (I), R1 and R2 each indicates a hydrogen atom, an alkyl group having 1 to 20 carbons, an alkenyl group having 1 to 20 carbons, or an alkynyl group having 1 to 20 carbons, R1 and R2 may be the same or different, and M+ indicates sodium ion, potassium ion, or lithium ion.
