Bio-based polymers aeroge oil absorption material disclosed by the invention is first to be crosslinked to obtain precursor liquid to bio-based polymers with crosslinking agent, then precursor liquid is freeze-dried and obtains aeroge, hydrophobic bio-based polymers aeroge oil absorption material finally is obtained in aeroge surface grafting silane, density is 3.8~23.1kg/m 3 Water contact angle is at least 117.8 °, adsorption capacity to gasoline, paraffin oil, chloroform and crude oil is respectively 30.5~109.0g/g, 33.2 131.2g/g, 58.2 163.0g/g, 24.7 95.8g/g, and the material, after 50 adsorbed gasoline extrusion cycles, the conservation rate of adsorption capacity is 43~99%.Not only absorbency capacity is big for aeroge oil absorption material disclosed by the invention, oil suction is efficient, and the conservation rate of higher adsorption capacity can be repeatedly circulated and kept by simple extruding, the raw material sources for preparing use simultaneously are extensive, cheap and easy to get, it prepares simple, it is ripe, it is environmentally friendly, meet the needs of sustainable development. |
