Hydrophobic modifier composition and hydrophobic sponge material as well as preparation method and application thereof

The invention relates to the field of removal of organic pollutants in water, in particular to a hydrophobic modifier composition and a hydrophobic sponge material as well as a preparation method and application thereof. The hydrophobic modifier composition comprises polyvinyl chloride, nano silicon dioxide and liquid siloxane; wherein the mass ratio of the polyvinyl chloride to the nano silicon dioxide to the liquid siloxane is (800-1200): (200-4800): 1. The hydrophobic sponge material obtained by using the hydrophobic modifier composition can quickly and effectively separate oil from water, can still keep higher adsorption capacity after being recycled for multiple times, and can be used for emergency treatment of oil leakage on water. 本发明涉及水中有机污染物去除领域，特别涉及疏水改性剂组合物和疏水海绵材料及其制备方法和应用。所述疏水改性剂组合物包含聚氯乙烯、纳米二氧化硅和液态硅氧烷；其中，聚氯乙烯、纳米二氧化硅和液态硅氧烷的质量比为(800-1200)：(200-4800)：1。使用本发明所述疏水改性剂组合物得到的疏水海绵材料能够快速有效的对油/水进行分离，并且经多次循环使用后仍可保持较高的吸附容量，可用于水上油品泄漏应急处理。
