Oil-resistant porous adsorption resin and preparation method thereof

The invention discloses oil-resistant porous adsorption resin and a preparation method thereof, the resin comprises an oil phase and a water phase, an oil-soluble organic polymer and resin are added into the water phase for suspension polymerization reaction, finally, the temperature is increased, and Friedel-Crafts alkylation reaction is performed under the catalytic action to obtain the adsorption resin. The cyano resin, the chlorinated polyether polymer, the acrylic monomer with the phosphate group and the unsaturated monomer with the sulfonic acid group are copolymerized, and the catalyst is subsequently added to carry out alkylation reaction for further crosslinking, so that the obtained adsorption resin is tough and has high strength, and therefore, the adsorption resin has the characteristics of oil resistance, high mechanical strength and the like; and compared with the existing adsorption material, the adopted raw materials and process are greatly different. According to the invention, except for the
