Abstract

A method for forming a golf ball core with a nanofiller masterbatch is disclosed herein. The method includes mixing the nanofiller masterbatch, a graphene masterbatch material with other materials to form a core mixture, wherein the masterbatch preferably comprises 1-80% by weight of nanofillers and 20-99% by weight of a carrier polymer.

Claims (5)

1. A golf ball comprising:

a core formed from a reaction of core mixture comprising a first masterbatch ranging from 50 to 90 weight percent of the core mixture, a graphene masterbatch ranging 1 to 10 weight percent of the core mixture, barium sulfate ranging 1 to 5 weight percent of the core mixture, a peroxide ranging 0.2 to 1 weight percent of the core mixture, and zinc bis(pentachlorothiophenolate) ranging 0.2 to 1 weight percent of the core mixture; and

a cover disposed over the core.

2. The golf ball according to claim 1 wherein the first masterbatch comprises 5.9% Zinc oxide, 37.1% ZDA, 57.0% polybutadiene.

3. The golf ball according to claim 1 wherein the first masterbatch comprises 1-10 weight percent zinc oxide, 30 to 50 weight percent zinc diacrylate, and 40 to 80 weight percent polybutadiene.
