Description

一种耐老化体育训练用胶管及其制备方法 技术领域
本发明属于体育训练器材技术领域，具体涉及一种耐老化体育训练用胶管及其制备方法。
 背景技术
随着人类生存质量的改善和生活水平的提高，对环境健康和空气质量的要求也越来越高。在满足基本的居住和生活要求之外，人们要求我们的生活用品、健身器材具备更多有利于清洁健康和改善微观环境的功能，使其具有环境协调和健康作用。
负离子是指带一个或多个负电荷的离子，亦称“阴离子”。空气中的负离子不仅能促成人体合成和储存维生素，强化和激活人体的生理活动；还具有杀灭病菌、净化空气，促进人体新陈代谢，提高人体免疫能力，增强人体肌能，调节肌体功能平衡的作用。电气石(Tourmaline, 也叫托玛琳) 是一种独特的天然负离子功能矿物材料, 其成分和结构极为复杂。电气石的晶体沿纵轴方向的两个端面分别带有自然生成的电气正、负极性, 具有压电和热释电功能, 在受热、受压或者受到其它能量激发时都会产生电荷, 释放出负离子。
 技术问题
弹性阻力训练系列包括弹力带、弹力管及弹性阻力配件。目前市场上有不同规格的应用于体育训练的胶管，但是没有发现有释放负离子的胶管。同时，在使用过程中，由于经常性的剧烈伸缩，而且由于结构和制备工艺的限制，胶管的使用寿命也不长。
