Description

一种棒球用合成革
技术领域
本发明涉及合成革技术领域，尤其涉及一种棒球用合成革。
背景技术
棒球运动是一种以棒打球为主要特点，集体性、对抗性很强的球类运动项目。它在国际上开展较为广泛，影响较大，被誉为“竞技与智慧的结合”。在美国、日本尤为盛行，被称为“国球”。
棒球是圆形软木、橡胶或类似物质作球心，绕以麻线，再以两块白色马皮或牛皮包紧平线密缝而成。由于人口的膨胀、社会需求的不断增加，马皮、牛皮资源日益显得不足，价格昂贵，并且马皮、牛皮的机械性能和耐磨性不能满足棒球表面覆盖层的要求。
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用合成革，本发明具有良好的机械性能和耐磨性。
本发明提出的一种棒球用合成革，包括基布和聚氨酯组合物，其中，聚氨酯组合物的原料按重量份包括：改性聚氨酯乳液100-150份，水10-20份，竹炭粉10-15份，改性硅藻土25-35份，聚四氟乙烯4-6份，消泡剂0.5-1份，白色颜料2-8份，防霉剂0.5-1份，磺基琥珀酸双十三烷基酯钠1-2份。
优选地，聚氨酯组合物的原料按重量份包括：改性聚氨酯乳液120-130份，水13-17份，竹炭粉11-13份，改性硅藻土28-32份，聚四氟乙烯4.5-5.5份，消泡剂0.7-0.9份，白色颜料4-6份，防霉剂0.6-0.8份，磺基琥珀酸双十三烷基酯钠1.2-1.8份。
优选地，竹炭粉为800-1000目，聚四氟乙烯为1000-2000目。
优选地，改性硅藻土为γ-氨丙基三乙氧基硅烷改性硅藻土，其为400-600目。
优选地，消泡剂为乳化硅油和聚氧乙烯聚氧丙烯季戊四醇醚的混合物。
优选地，在改性聚氨酯乳液的制备过程中，在氮气氛围中，将4,4’-二苯甲烷二异氰酸酯、聚乙二醇1000、二羟甲基丙酸、丙酮、二月桂酸二丁锡混匀，升温，保温搅拌，加入改性碳化硅，继续搅拌，然后加入1,4-丁二醇，继续搅拌，接着加入季戊四醇三丙烯酸酯，继续搅拌得到聚氨酯预聚体溶液；向聚氨酯预聚体溶液中加入甲基丙烯酸丁酯和偶氮二异丁腈，搅拌，加入三乙胺中和，加水剪切乳化，减压蒸发除去丙酮得到改性聚氨酯乳液。
优选地，在改性聚氨酯乳液的制备过程中，在氮气氛围中，将4,4’-二苯甲烷二异氰酸酯、聚乙二醇1000、二羟甲基丙酸、丙酮、二月桂酸二丁锡混匀，升温至48-52℃，保温搅拌1-2h，加入改性碳化硅，继续搅拌2-3h，然后加入1,4-丁二醇，继续搅拌60-90min，接着加入季戊四醇三丙烯酸酯，继续搅拌40-60min得到聚氨酯预聚体溶液；向聚氨酯预聚体溶液中加入甲基丙烯酸丁酯和偶氮二异丁腈，搅拌1-2h，加入三乙胺中和，加水剪切乳化，减压蒸发除去丙酮得到改性聚氨酯乳液。
优选地，在改性聚氨酯乳液的制备过程中，改性碳化硅为γ-氨丙基三乙氧基硅烷改性碳化硅。
优选地，在改性聚氨酯乳液的制备过程中，4,4’-二苯甲烷二异氰酸酯、聚乙二醇1000、二羟甲基丙酸、二月桂酸二丁锡、改性碳化硅、1,4-丁二醇、季戊四醇三丙烯酸酯、甲基丙烯酸丁酯、偶氮二异丁腈和水的重量比为20-30：40-60：1.6-2.4：0.04-0.06：1.2-1.8：1-1.5：0.6-0.9：1.6-2.4：0.06-0.09：50-60。
上述改性聚氨酯乳液的制备过程中，丙酮是反应溶剂，不规定其用量，根据具体操作确定其用量。
本发明的制备方法为：将改性聚氨酯乳液、水、竹炭粉、改性硅藻土、聚四氟乙烯、消泡剂、白色颜料、防霉剂、磺基琥珀酸双十三烷基酯钠混匀得到聚氨酯组合物；将聚氨酯组合物均匀涂覆在基布上，烘干得到棒球用合成革。
本发明选用的竹炭粉、改性硅藻土、聚四氟乙烯具有良好的耐磨性和抗冲击性，三者相互配合，可以大大增加聚氨酯组合物的耐磨性和抗冲击性；不同粒径的竹炭粉、改性硅藻土、聚四氟乙烯相互配合，可以进一步增加聚氨酯组合物的机械性能；碳化硅具有优异的耐磨性，质量较轻且强度高，γ-氨丙基三乙氧基硅烷改性碳化硅可以与4,4’-二苯甲烷二异氰酸酯、聚乙二醇1000、二羟甲基丙酸、丙酮均匀分散，并通过氨基与异氰酸酯基反应，将碳化硅接枝到聚氨酯预聚体中，大大增加聚氨酯耐磨性和强度；然后通过季戊四醇三丙烯酸酯与异氰酸酯基反应，将碳碳双键接枝到聚氨酯两端，再与甲基丙烯酸丁酯在引发剂偶氮二异丁腈作用下发生双键缩合，从而将甲基丙烯酸丁酯接枝到聚氨酯中，形成交联网络，大大增加聚氨酯的机械性能和粘结性，且可以使得本发明的颜色保持不变，不泛黄；碳化硅、甲基丙烯酸丁酯和聚氨酯在分子内相互配合，并结合竹炭粉、改性硅藻土、聚四氟乙烯的外在配合，从而大大增加本发明的耐磨性和机械性能，并且使得聚氨酯组合物具有良好的粘度，与基布紧密粘结，从而进一步增加本发明的韧性和强度；竹炭粉、硅藻土与防霉剂相互配合，可以增加本发明的防霉性能；磺基琥珀酸双十三烷基酯钠可以促进聚氨酯组合物凝固干燥；聚氨酯组合物未用到有机溶剂，可以减少对环境的污染；上述各物质相互配合，使得本发明具有良好的机械性能和耐磨性。
