背景技术
海绵制品已经在人们生活中逐渐普及，其中有海绵制作的座椅、沙发、床垫等家居物品，聚醚多元醇是生产聚氨酯海绵的主要原料，现有的聚氨酯海绵生产一般采用的聚醚多元醇通常采用石油类聚醚多元醇，然而石油类聚醚多元醇制成的聚氨酯稳定性高，自然状态下难以分解；使之不具有可降解性，不利于环境保护和可持续发展，随着海绵制品的应用领域的扩大，市场需要大量的海绵供给，由于现行的海绵存在很多性能缺陷，使用海绵就存在安全隐患。
发明内容
本发明的目的在于提供一种绿色环保海绵及其制备方法。
为了实现上述目的本发明采用如下技术方案：
一种绿色环保海绵，其特征在于其组成原料的重量份为：聚氧化丙烯二醇70-80、四氢呋喃-氧化丙烯共聚二醇30-40、异佛尔酮二异氰酸酯18-25、纳米级二氧化钛3-4、氧化锆10-15、双（二甲基胺基乙基）醚1.5-2.0、二硫醇二丁基锡0.35-0.45、耐火无机胶泥3.0-5.0、改性剂6.0-8.0、聚乙烯吡咯烷酮1.5-2.0和水4.0-6.0；
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。
所述的绿色环保海绵的制备方法，其特征在于先将上述配方量的聚氧化丙烯二醇、四氢呋喃-氧化丙烯共聚二醇、异佛尔酮二异氰酸酯、耐火无机胶泥、改性剂投入混合器中混合，搅拌均匀，并加热至40-45℃，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1-3分钟后倒入模具发泡并固化后，得到绿色环保海绵。
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：
本发明具有优良的柔软性、弹性、防静电、耐水性的特点，本发明不添加有机溶剂和甲苯二异氰酸酯，从而避免有机溶剂和甲苯二异氰酸酯高挥发性造成的危害，对环境无污染，对人体无损害，绿色环保。
