GOLF BALL AND METHOD FOR MANUFACTURING THE SAME

摘要

A method for manufacturing a golf ball showing a great flight distance on driver shots for includes the steps of: preparing a rubber composition containing a base rubber, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a metal salt thereof as a co-crosslinking agent, a crosslinking initiator and a carboxylic acid and/or a salt thereof; heat pressing the rubber composition at a press temperature ranging from t-40° C. to t-15° C. to mold a spherical core, wherein t ° C. is a one-minute half-life temperature of the crosslinking initiator; and forming at least one cover layer covering the spherical core.

1. A method for manufacturing a golf ball that comprises a spherical core and at least one cover layer covering the spherical core, comprising the steps of:
preparing a rubber composition containing a base rubber, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a metal salt thereof as a co-crosslinking agent, a crosslinking initiator and a carboxylic acid and/or a salt thereof, provided that the rubber composition further contains a metal compound in the case of containing only the α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms as the co-crosslinking agent; heat pressing the rubber composition at a press temperature ranging from t-40° C. to t-15° C. to mold the spherical core, wherein t ° C. is a one-minute half-life temperature of the crosslinking initiator; and forming at least one cover layer covering the spherical core.
