Abstract:
1. A preparation method of an oil absorbent material, which comprises: (1) mixing and stirring well a monomer A, a vinyl monomer, an initiator and a vesicant to form a copolymerization system, wherein the amount of the monomer A is in the range of approximately 10-50 wt %, the amount of the vinyl monomer is in the range of approximately 48-88 wt %, the amount of the initiator is in the range of approximately 0.01-5 wt %, the amount of the vesicant is in the range of approximately 1-5 wt %; wherein, the monomer A is selected from the group consisting of: Acrylamide, Hydroxyethyl acrylate, Hydroxypropyl acrylate, Tri(ethylene glycol) divinyl ether, functional monomer T-1168, functional monomer TM-200 and Acrylic ester; wherein, the vinyl monomer is selected from the group consisting of: α-methylstyrene, Pentaerythritol tetramethyacrylate, Tri(propylene glycol) diacrylate or Diethylene glycol diacrylate, wherein R (2) immersing a fiber carrier into the copolymerization system to adsorb the copolymerization system on the fiber carrier, and then heating the fiber carrier and the copolymerization system at a temperature between 60˜80° C. for 1˜4 hours to initiate a polymerization reaction and to synthesize porous sponge-like oil absorbent polymers on the fiber carrier; wherein the fiber carrier is selected from the group consisting of: polypropylene fiber, acrylic fiber, polyacrylonitrile fiber, sponge, aramid fiber, and non-woven fabrics.
