Description

一种棒球用耐磨防脱落合成革
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耐磨防脱落合成革。
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耐磨防脱落合成革，本发明耐磨性好，重量轻，机械性能好，聚氨酯组合物与基布粘结性好，不易脱落。
本发明提出的一种棒球用耐磨防脱落合成革，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100-120份，丙烯酸酯乳液10-30份，水10-15份，陶土8-12份，轻质碳酸钙20-30份，竹炭粉15-20份，聚二甲基硅氧烷0.2-0.4份，聚氧丙烯甘油醚0.3-0.5份，颜料4-6份，防霉剂0.2-0.8份，十二烷基硫酸钠1-2份。

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、丙烯酸酯乳液、水、陶土、轻质碳酸钙、竹炭粉、聚二甲基硅氧烷、聚氧丙烯甘油醚、颜料、防霉剂、十二烷基硫酸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，烘干得到棒球用耐磨防脱落合成革。
本发明选用的陶土、轻质碳酸钙、竹炭粉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；不同粒径的陶土、轻质碳酸钙、竹炭粉相互配合，可以进一步增加聚氨酯组合物的机械性能；二氧化硅具有很好的耐磨性、抗冲击性和耐高温性，γ-氨丙基三乙氧基硅烷改性二氧化硅可以与异佛尔酮二异氰酸酯、聚四氢呋喃醚二醇1000、二羟甲基丁酸、丙酮均匀分散，并通过氨基与异氰酸酯基反应，将二氧化硅接枝到聚氨酯预聚体中，大大增加聚氨酯耐磨性、抗冲击性和耐高温性；然后通过甲基丙烯酸羟乙酯与异氰酸酯基反应，将碳碳双键接枝到聚氨酯两端，再与丙烯酸甲酯在引发剂过氧化苯甲酰作用下发生双键缩合，从而将丙烯酸甲酯接枝到聚氨酯中，形成交联网络，大大增加聚氨酯的机械性能和粘结性；二氧化硅、丙烯酸甲酯和聚氨酯在分子内相互配合，并结合陶土、轻质碳酸钙、竹炭粉的外在配合，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耐高温性和粘度，与丙烯酸酯乳液相互配合，大大增加聚氨酯乳液的粘度，使其与基布紧密粘结，从而进一步增加本发明的韧性和强度，且可以使得本发明的颜色保持不变，不容易泛黄；竹炭粉与防霉剂相互配合，可以增加本发明的防霉性能；十二烷基硫酸钠可以促进各物质均匀分散；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耐磨性、机械性能和粘结性，聚氨酯组合物与基布粘结性好，不易脱落。
