Abstract

本发明提供了一种用于反光运动用球的层状材料，其中，层状材料包括基材层、反光材料层和硅胶颗粒层；基材层和硅胶颗粒层分别邻接于反光材料层的两侧，且硅胶颗粒层不完全覆盖反光材料层。本发明还提供了层状材料的制备方法，其包括以下步骤：1)将基材层与反光材料层接合；2)将硅胶颗粒层施加到反光材料层；3)在60‑100摄氏度下烘烤5‑15分钟；4)重复步骤2)和3)2‑12次。本发明还提供了层状材料在反光运动用球中的应用以及一种反光运动用球。由本发明提供的层状材料制成的运动用球，能够很轻松地被抓稳，不易滑落，这使得反光运动用球才能够正真地被使用。由本发明提供的反光运动用球弹性好、反光材料层也不容易被磨耗掉。

Description

用于反光运动用球的层状材料及其制备方法和反光运动用球
技术领域
本发明涉及一种反光运动用球的层状材料，该层状材料的制备方法，以及一种反光运动用球。
背景技术
随着物质生活水平的提高，锻炼身体也越来越受到重视。然而，当今的生活节奏越来越快，越来越多的人选择在晚上锻炼身体。
球类运动一直是人们最喜爱的运动项目之一。进行球类运动时，良好的照明是必备条件之一。然而，在室外的运动场地，许多地方照明明显不足，导致不能够容易看清运动的球，因此这大大限制了在晚上的打球活动。
发明内容
为此，本发明为了解决现有技术的缺陷，一方面提供了一种用于反光运动用球的层状材料，其特征在于，该层状材料包括基材层、反光材料层和硅胶颗粒层；其中所述基材层和所述硅胶颗粒层分别邻接于所述反光材料层的两侧，且所述硅胶颗粒层不完全覆盖所述反光材料层。
另一方面，本发明提供了一种用于反光运动用球的层状材料的制备方法，该方法包括以下步骤：
1)将基材层与反光材料层接合；
2)将硅胶颗粒层施加到反光材料层；
3)在60-100摄氏度下烘烤5-15分钟；
4)重复步骤2)和3)2-12次，优选为4-10次。
