本发明涉及一种海绵的制备方法，具体涉及一种含有石墨烯的海绵及其制备方法。
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，三羟甲基丙烷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三羟甲基丙烷聚醚多元醇通常采用石油类三羟甲基丙烷聚醚多元醇，然而石油类三羟甲基丙烷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含有石墨烯的海绵及其制备方法。
为了实现上述目的本发明采用如下技术方案：
一种含有石墨烯的海绵，其特征在于其组成原料的重量份为：三羟甲基丙烷聚醚60-80、醋酸纤维10-15、丙三醇4.5-6.5、1,6-己二异氰酸酯（HDI）20-25、硅灰石粉5-6、石墨烯5-6、尿素2.5-3.0、4,4’- 氧代双苯磺酰肼0.5-0.6、二氯甲烷2.3-2.8、2,4,6- 三( 二甲氨基甲基) 苯酚0.5-0.9、乙二醇单丁醚6.5-7.5、改性剂4-5和水10-15；
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。
所述的含有石墨烯的海绵的制备方法，其特征在于先将上述配方量的三羟甲基丙烷聚醚、1,6-己二异氰酸酯（HDI）、丙三醇、乙二醇单丁醚、改性剂投入混合器中混合，搅拌均匀，并加热至35 -40 ℃，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，得到含有石墨烯的海绵。
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，而且硅灰石粉吸水性好，提高了海绵的吸水性，本发明的石墨烯具有超强的憎水性，对有机溶剂和油脂具有吸附能力强、吸附速度快的特点，从而增强了海绵对有机溶剂和油脂的吸附。
