所述的改性剂的制备方法为：将25-30重量份水加入反应容器，加热到80-90℃；取羧甲基纤维素2-3重量份加入水中，搅拌溶解，再加入0.1-0.15重量份纳米碳粉、1.2-1.3重量份吗啉、1-1.2重量份聚氧乙烯醚、1-2重量份丙烯酸，搅拌均匀，降温至20-30℃，加入0.2-0.3重量份的过硫酸钠，搅拌均匀，反应30-45分钟，然后，再加入1-2重量份儿茶酚、0.1-0.2重量份2-正辛基-4-异噻唑啉-3-酮，继续搅拌反应45-60分钟，即得。
所述的高抗聚氨酯海绵的制备方法，其特征在于包括以下步骤：先将上述配方量的聚乙二醇单甲醚、异佛尔酮二异氰酸酯、聚氨酯树脂、改性剂投入混合器中混合，搅拌均匀，并加热至25-35℃，再将上述配方量的其它剩余成分投入混合器中混合，高速搅拌10-30秒钟后倒入模具发泡并固化后，得到高抗聚氨酯海绵。
本发明的改性剂能增加海绵的耐腐蚀、霉变生菌性能及柔软性与回弹性。
本发明的有益效果：
本发明具有优秀的抗氧化、抗光照和抗老化的特点，聚氨酯树脂是具有高强度、抗撕裂、耐磨等特性的高分子材料，大大提高海绵的抗性。
