Abstract
The object of the present invention is to provide a golf ball with superior abrasion resistance and resilience. The present invention provides a golf ball of the present invention comprises a core and a cover that covers the core. The cover contains a polyurethane resin and an organically modified layered silicate, and an interlayer distance of the organically modified layered silicate measured by X-ray diffraction is in a range from 2.5 nm to 15 nm.
Claims14
A golf ball comprising a core and a cover that covers the core, wherein
- the cover contains a polyurethane resin and an organically modified layered silicate, and
- an interlayer distance of the organically modified layered silicate measured by X-ray diffraction is in a range from 2.5 nm to 15 nm.
A golf ball comprising a core and a cover that covers the core, wherein the cover contains
- a polyurethane resin having a melt viscosity (210° C.) ranging from 1,500 P to 30,000 P, 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
- an interlayer distance of the organically modified layered silicate measured by X-ray diffraction is in a range from 2.5 nm to 15 nm.
A golf ball manufacturing method for manufacturing a golf ball, comprising the steps of:
- organically modifying a layered silicate by using an organic cation to prepare 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, a polyurethane resin, and an additive.
