▎ 摘  要

NOVELTY - Golf ball 10 comprises core comprising 40-90 wt.% polybutadiene, 10-50 wt.% zinc diacrylate, 1-30 wt.% zinc oxide, 1-20 wt.% zinc stearate, 0.1-10 wt.% peroxide initiator and 0.1-5.0 wt.% graphene material. The inner mantle layer is set over core. The inner mantle 14a layer has thickness of 0.03-0.09 inch. The outer mantle layer is set over inner mantle layer. The outer mantle 14b layer has thickness of 0.025-0.050 inch. The cover 16 layer is set over outer mantle layer. USE - Golf ball. ADVANTAGE - The golf ball improves thermal stability, impact strength and aging properties, and enhances durability. DESCRIPTION OF DRAWING(S) - The drawing shows exploded partial cut-away view of golf ball. Inner core (12a) Golf ball (10) Inner mantle (14a) Outer mantle (14b) Cover (16)
