titleOfInvention | Method for manufacturing spherical core and golf ball |
abstract | An object of the present invention is to improve the production efficiency of a method for producing a spherical core having a small hardness difference between the surface hardness and the central hardness. SOLUTION: The method for producing a spherical core of the present invention comprises (a) a base rubber, (b) a co-crosslinking agent, an α, β-unsaturated carboxylic acid having 3 to 8 carbon atoms and / or a metal salt thereof, A rubber composition for a core containing (c) a crosslinking initiator and (d) a terpene-based resin is pressed under the conditions of a press temperature of 125 ° C. to 180 ° C., a press pressure of 1 MPa to 25 MPa, and a press time of 15 minutes to 40 minutes. It is characterized by comprising a step of cross-linking the rubber composition for core by pressurizing to form a spherical core. [Selection diagram] None |
