Abstract
The object of the present invention is to provide a golf ball having excellent durability and resilience. The present invention provides a golf ball which includes a core, and a cover covering the core. The cover contains an ionomer resin and an organically modified layered silicate. The organically modified layered silicate has an interlayer distance, measured by X-ray diffraction, in a range from 2.5 nm to 15 nm.
Claims14
A golf ball comprising a core and a cover covering the core, wherein
- the cover contains an ionomer resin and an organically modified layered silicate, and
- the organically modified layered silicate has an interlayer distance, measured by X-ray diffraction, in a range from 2.5 nm to 15 nm.
A golf ball comprising a core and a cover covering the core, wherein
- the cover contains
- an ionomer resin having a melt flow rate (190° C., 2.16 kg) in a range from 0.5 g/10 min to 15 g/10 min, and
- an organically modified layered silicate which is obtained by modifying a layered silicate selected from a smectite group consisting of montmorillonite, beidellite, nontronite, saponite, ferrous saponite, hectorite, sauconite, and stevensite by an organic ammonium ion and which has an interlayer distance, measured by X-ray diffraction, in a range from 2.5 nm to 15 nm.
A method for producing a golf ball, comprising the steps of:
- organically modifying a layered silicate by an organic cation to produce an organically modified layered silicate;
- and
- forming a cover such that the organically modified layered silicate in the cover has an interlayer distance, measured by X-ray diffraction, in a range from 2.5 nm to 15 nm, by using the organically modified layered silicate, an ionomer resin, and an additive.
