    • PROBLEM TO BE SOLVED: To provide a golf ball cover having an excellent mechanical strength and cut/shearing resistance and furthermore light stability. SOLUTION: A golf ball 20 including a cover material made of a polyurea composition is provided. In one version, the golf ball 20 includes a polybutadiene core 22 and a coating cover layer 24 made of the polyurea composition. In another version, the golf ball 20 includes the polybutadiene core 22, an intermediate casing layer made of an ionomer resin and an outer cover layer 24 made of the polyurea composition. The polyurea composition is the reaction product of alycyclic isocyanate and amine compound. Diisocyanate is selected from 1,3-bis(isocyanatomethyl)cyclohexane, 1,4-bis(isocyanatomethl)cyclohexane and the mixture thereof. The resulting cover material has many advantageous characteristics including improved durability, toughness and light stability. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供具有优异的机械强度和切割/剪切阻力以及光稳定性的高尔夫球罩。 解决方案:提供一种包括由聚脲组合物制成的覆盖材料的高尔夫球20。 在一个版本中,高尔夫球20包括聚丁二烯芯22和由聚脲组合物制成的涂层覆盖层24。 在另一种形式中,高尔夫球20包括聚丁二烯芯22,由离聚物树脂制成的中间壳体层和由聚脲组合物制成的外覆盖层24。 聚脲组合物是亚环异氰酸酯和胺化合物的反应产物。 二异氰酸酯选自1,3-双(异氰酸根合甲基)环己烷,1,4-双(异氰酸甲酯)环己烷及其混合物。 所得的覆盖材料具有许多有利的特性,包括改进的耐久性,韧性和光稳定性。 版权所有(C)2011,JPO&INPIT
