本发明具有以下有益效果：
通过选用超低分子量的AS树脂，提高了材料的流动性，降低了成型过程中产生的内应力，引入全氟烷基的丙烯酸系添加剂作为耐化学品改性剂，该添加剂的迁移效率极高，在成型的过程中即可完全迁移到表面形成一种保护膜，这层保护膜和水不相容且具有较强的耐酸碱的性能，从而添加了该类添加剂的外皮层在遇到外饰漆等较强腐蚀漆时，表面会存在巨大的表面张力，阻止了强腐蚀漆进入到材料内部；采用红外反射钛白粉，可以大幅度反射太阳光的可见光和红外部分能量，加之导热填料的热释放的协同贡献，可以使较大幅度地降低外皮层的表面温度，长期耐候性佳；所得的海绵具有超柔软，手感好，不易撕破，不易变形，抗菌防臭等优点。本发明通过合理的原料的配比和结构构造，获得了一种超软的合成皮革健身足球，具有很好的柔软性、韧性、耐候性、阻燃性、热稳定性和耐腐蚀性，表面平整光滑，可光脚使用。
