Description

一种棒球棒用手柄胶料
技术领域
本发明涉及聚氨酯材料技术领域，尤其涉及一种棒球棒用手柄胶料。
背景技术
棒球棒是棒球比赛中击球员用来击球的棒子，呈圆柱形，棒面平滑无截面接头。目前，常用棒球棒以金属材料的棒球棒为主流，金属棒的两端必须密封，棒长不得超过1.07米，最粗处直径不得超过7厘米，握棒部分的棒帽末端可以直径不超过为2.45厘米。为便于握棒，在握棒的一端起至45.7厘米的长度内可用布条、胶布带或橡胶包缠。然而，以布条、胶布带或橡胶作为棒球棒手柄包缠料的耐磨、防滑、手感性能差，不能满足人们需求。
发明内容
基于背景技术存在的技术问题，本发明提出了一种棒球棒用手柄胶料，具有手感好、耐磨、防滑、可透气透湿的特点。
本发明提出一种棒球棒用手柄胶料，其原料按重量份包括：面层料20-40份，发泡底层料60-80份；其中，面层料原料按重量份包括：水性聚碳酸酯型聚氨酯树脂80-120份，聚氨酯增稠剂1.5-3.5份，消泡剂1-1.5份，润湿剂0.8-1.6份，手感剂0.5-2份；发泡底层料原料按重量份包括：水性聚醚型聚氨酯树脂80-120份，聚丙烯酸酯增稠剂2-4份，填料3-6份，发泡剂3-6份，交联剂1.5-4.5份。
优选地，水性聚碳酸酯型聚氨酯树脂的固含量为40-60％，水性聚醚型聚氨酯树脂的固含量为30-60％。

优选地，润湿剂为脂肪酸酯硫酸盐和/或聚氧乙烯烷基酚醚。
优选地，填料为纳米白炭黑和/或纳米硅藻土。
优选地，发泡剂为微球发泡粉，优选为松本微球发泡粉。
优选地，交联剂为碳化二亚胺和/或氮丙啶。
优选地，面层料原料按重量份包括：水性聚碳酸酯型聚氨酯树脂95-105份，聚氨酯增稠剂2-3份，消泡剂1.2-1.4份，润湿剂1.0-1.4份，手感剂1.0-1.5份；发泡底层料原料按重量份包括：水性聚醚型聚氨酯树脂90-110份，聚丙烯酸酯增稠剂2.5-3.5份，填料4-5份，发泡剂4-5份，交联剂2-3份。
本发明以水性聚碳酸酯型聚氨酯树脂为基料，配合聚氨酯增稠剂、消泡剂、润湿剂、手感剂制得手柄胶料面层料，以水性聚醚型聚氨酯树脂为基料，配合聚丙烯酸酯增稠剂、填料、发泡剂、交联剂制得手柄胶料发泡底层料，其中，水性聚碳酸酯型聚氨酯树脂的耐磨、抗氧化、抗撕裂性能优异，手感好、可透气透湿；水性聚醚型聚氨酯树脂的耐水性能好、手感柔软，发泡剂的发泡作用可显著提高底层料的透气透湿性能，填料具有很好的支撑作用，提高底层料的肉感，交联剂促进发泡过程中水性聚醚型聚氨酯树脂分子链的交联，提高底层料的强度；本发明以水性聚氨酯树脂为面底料原料，配合助剂制得手柄胶料，具有耐磨和透气透湿性能优异、手感好的特点，适合棒球棒使用。
