  公开号：US10029151B2

  公开（公告）日：2018-07-24

  A golf ball includes a single core having an outer surface and a geometric center. The core is formed from a substantially homogenous rubber composition. An inner cover layer is disposed about the core, the inner cover including a high-acid ionomer and having a material hardness of about 66 to 75 Shore D. The high-acid ionomer has an acid content of about 16% or greater. An outer cover layer is disposed about the inner cover layer, the outer cover including a polyurethane and having a material hardness of about 38 Shore D to about 56 Shore D. The core surface hardness is from 0 Shore C to 15 Shore C lower than the geometric center hardness to define a hardness gradient.

  高尔夫球包括一个具有外表面和几何中心的球芯。球芯由基本均匀的橡胶成分形成。内包层围绕球芯设置，内包层包括高酸离子聚合物，材料硬度约为 66 至 75 邵氏硬度 D，高酸离子聚合物的酸含量约为 16% 或更高。核心表面硬度比几何中心硬度低 0 至 15 肖氏硬度，从而形成硬度梯度。

  Golf ball comprising a core having a hardness gradient and an outer cover layer having a microhardness gradient and being formed from a thermoset polyurethane material throughout, and having: i) a treated region that is contacted with a thermoset polyurethane microhardness-increasing solution consisting of an isocyanate portion and at least one non-aqueous solvent; and ii) an untreated region that is not contacted with the thermoset polyurethane microhardness-increasing solution. The treated region comprises the isocyanate portion, whereas the untreated region does not comprise the isocyanate portion. Treated region has a microhardness M1 that is greater than microhardness M2 of untreated region to define the outer cover layer positive microhardness gradient ΔM=M1−M2. The treated region may have a depth Dtr that extends inward from the cover outer surface and in some embodiments is less than a thickness of the untreated region. Treated region may alternatively extend from the inner surface toward outer surface.

  高尔夫球，包括一个具有硬度梯度的球芯和一个具有微硬度梯度的外包层，整个外包层由热固性聚氨酯材料形成，并具有：i) 与由异氰酸酯部分和至少一种非水溶剂组成的热固性聚氨酯微硬度增加溶液接触的处理区域；以及 ii) 未与热固性聚氨酯微硬度增加溶液接触的未处理区域。处理区包括异氰酸酯部分，而未处理区不包括异氰酸酯部分。处理区的显微硬度 M1 大于未处理区的显微硬度 M2，以确定外覆盖层的正显微硬度梯度 ΔM=M1-M2。处理区可具有从覆盖层外表面向内延伸的深度 Dtr，在某些实施例中小于未处理区的厚度。处理区也可以从内表面向外表面延伸。

  Golf ball having CoR of at least 0.700 and compression of at least 50 and comprising a layer of a mixture of thermoset or thermoplastic composition and a plurality of conductive nanoshelled structures such as conductive hollow nanoshells and/or nanorice particles. Conductive nanoshelled structures may be included in amount of from about 2 wt % to greater than 50 wt. % of total weight of mixture. Diameter of each conductive nano shelled structure at widest cross-section may be up to 1000 nm. Each conductive hollow nanoshell may have shell thickness to longitudinal diameter ratio of from about 1:3 to about 1:100. Each nanorice particle may have longitudinal diameter of up to 1000 nm. Shell thickness can be from 1 nm to 100 nm and may be controlled. A layer consisting of mixture may have specific gravity that differs from specific gravity of a layer consisting of the thermoset or thermoplastic composition portion of mixture.
