Description

一种棒球用抗冲击耐紫外线合成革
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抗冲击耐紫外线合成革。
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，因此人们选用合成皮革代替马皮、牛皮。但是在温度底下的环境中，对合成皮革的耐低温性、机械性能要求更高，另外由于棒球训练频繁，长期暴露于日光下，因此要求棒球具有良好的耐老化、抗紫外线性能，但是现有合成革在耐低温、机械性能和抗老化性能方面还不能兼具。
