Clay sponge material as well as preparation method and application thereof
The invention discloses a clay sponge material as well as a preparation method and application thereof. The invention relates to the technical field of adsorption materials. The preparation method of the clay sponge material comprises the following steps: S1, polymerizing dopamine on a melamine sponge to prepare a polydopamine/melamine sponge; s2, weighing clay, dissolving the clay in deionized water, adding alkylsilane, putting the polydopamine/melamine sponge, stirring, washing and drying to obtain the hydrophobic clay sponge. According to the invention, dopamine is polymerized to adhere clay to melamine sponge, and then silicon dioxide particles hydrolyzed by silane are grafted, so that the obtained clay sponge material not only has enough hydrophobicity, but also has the antibacterial property of clay, can be directly placed on a polluted water surface to work, and can remove crude oil by physical extrusion after adsorbing the crude oil; and repeated use can be realized.
本发明公开了一种黏土海绵材料及其制备方法和应用。本发明涉及吸附材料技术领域。本发明的一种黏土海绵材料的制备方法，包括如下步骤：S1.将多巴胺聚合在三聚氰胺海绵上，制得聚多巴胺/三聚氰胺海绵；S2.称取黏土溶解于去离子水中，加入烷基硅烷，放入聚多巴胺/三聚氰胺海绵，搅拌，洗涤干燥后得到疏水型黏土海绵。本发明采用多巴胺聚合在三聚氰胺海绵上黏附黏土后接枝硅烷水解的二氧化硅颗粒，得到的黏土海绵材料既能够有足够的疏水性，也具有黏土自身的抗菌性，可直接放置于污染水面上进行工作，吸附原油后物理挤压即可将原油脱除，可重复使用。
