A three-dimensional porous oil-absorbing hydrogel and its preparation method and application |
| abstract |
The invention discloses a three-dimensional porous oil-absorbing hydrogel and its preparation method and application. It is made of components comprising the following proportions: acrylamide monomer: sheet-like hydrophilic nanoclay: persulfide: deionized water: N, N, N, N Tetramethylethylenediamine = 1-3g: 2-6g: 60-100mg: 20-25mL: 100-200μL. The surface of the hydrogel of the present invention is rough and the interior is porous. At the same time, because of the hydrophobic group of the acrylamide monomer, the dried hydrogel can absorb a large amount of oil substances. In terms of preparing loose and porous oil-absorbing hydrogel materials has far-reaching significance. Utilizing the hydrogel prepared by the invention to absorb slick oil has remarkable effect and complete separation. |
