Abstract
This invention relates to an oil-absorbent polymer and the preparation method thereof, and disclosed a preparation method of quick oil absorbent material, which comprises: (1) Mixing and stirring well monomer A, vinyl monomer, initiator and vesicant to form a copolymerization system, wherein the amount of monomer A is in the range of approximately 10-50 wt %, the amount of vinyl monomer is in the range of approximately 48-88 wt %, the amount of initiator is in the range of approximately 0.01-5 wt %, the amount of vesicant is in the range of approximately 1-5 wt %; (2) And then immersing fiber carriers into the liquid of above-said copolymerization system to adsorb the liquid on the fiber carriers, then heating the fiber carriers under a temperature between 60˜80° C. for 1˜4 hours to synthesize polymers on the fiber carriers. The quick oil absent material is less dense than water, and has both high adsorption capacity and high adsorption rate, meanwhile it can be repeatedly used and the absorbed valuable oils can be regenerated to reduce cost effectively.
