Description

一种增强海绵及其制备方法
技术领域
本发明涉及一种海绵的制备方法，具体涉及一种增强海绵及其制备方法。
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，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增强海绵及其制备方法。
为了实现上述目的本发明采用如下技术方案：
一种增强海绵，其特征在于其组成原料的重量份为：聚四氢呋喃醚二醇85-90、异佛尔酮二异氰酸酯50-55、二茂铁13-17、玻璃纤维10-15、N,N-二甲氨基乙基-N-甲基氨基乙醇3-5、氰尿酸锌0.8-0.9、三聚磷酸钠1.0-1.5、松香酸聚氧乙烯酯1.0-1.2、改性剂5-6和水8.0-9.0。
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。
所述的增强海绵的制备方法，其特征在于先将上述配方量的聚四氢呋喃醚二醇、异佛尔酮二异氰酸酯、二茂铁、改性剂投入混合器中混合，搅拌均匀，并加热至30-35℃，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3-5分钟钟后倒入模具发泡并固化后，得到增强海绵。
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、高弹性、耐水性的特点，而且纳米海泡石粉具有抗拉强度大、耐热性好、优良的电绝缘性、无机酸和有机酸的耐腐蚀性很强等特性，海绵的抗冲击性、抗疲劳性、柔韧性和高抗撕裂强度得到很大的提高。
具体实施方式
实施例1：增强海绵，其组成原料的重量份（kg）为：聚四氢呋喃醚二醇85、异佛尔酮二异氰酸酯55、二茂铁13、玻璃纤维15、N,N-二甲氨基乙基-N-甲基氨基乙醇5、氰尿酸锌0.8、三聚磷酸钠1.5、松香酸聚氧乙烯酯1.0、改性剂5和水9.0。
所述的改性剂的制备方法为：将25重量份水加入反应容器，加热到80-90℃；取羧甲基纤维素2重量份加入水中，搅拌溶解，再加入0.1重量份纳米碳粉、1.2重量份吗啉、1重量份聚氧乙烯醚、1重量份丙烯酸，搅拌均匀，降温至20-30℃，加入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重量份儿茶酚、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。
