Abstract

The invention provides a magnetic oil suction high-molecular material possessing a host-guest identification function and its preparation method. The method comprises the following steps: uniformly mixing a functional monomer, a cyclodextrin monomer, a cross-linking agent and magnetic nanoparticles, performing an ultrasonic reaction for 0.5-4 hours, adding an initiator and a pore forming agent, reacting for 2-8 hours at 60-85 DEG C after uniformly mixing, heating to 100-150 DEG C and heating for 1-6 hours, and then cooling to the room temperature to obtain the magnetic oil suction high-molecular material possessing the host-guest identification function. The material has the advantages that the host-guest effect of the cyclodextrin performs preferential adsorption to various crude oil molecules, so that the oil suction rate is fast, and the saturation oil absorbency is high. The oil suction high-molecular material can be used in large scale treatment of offshore crude oil leakage accidents and oil-water separation in industrial waste water.

Description

technical field [0001] The invention relates to a magnetic oil-absorbing polymer material and a preparation method thereof, belonging to the field of functional polymer materials for oil and gas fields. Background technique [0002] Crude oil spills will cause a lot of pollution, especially oil spills from oil tankers during sea transportation, or oil spills caused by accidents on offshore drilling platforms, which will cause large-scale marine pollution and cause serious damage to the ecosystem. At present, the main treatment methods for crude oil spill accidents are: in-situ burning of leaked crude oil, setting up isolation belts to isolate crude oil, cultivating microorganisms to degrade leaked crude oil, and using polymer oil-absorbing resin to absorb leaked crude oil. Among them, oil-absorbing resin is currently the most effective treatment method. [0003] There are two main working principles of polymer oil-absorbing resins when dealing with spilled crude oil. The fi...
