Problems solved by technology

The current research on super oil-absorbing resins for jet fuel is not deep enough
There is no report of porous superabsorbent resin developed for jet fuel in the prior art
In addition, the usual extraction methods such as leaching and Soxhlet extraction are mainly used in the post-polymerization extraction process. These methods often have problems such as long time consumption, high energy consumption, and large extraction dosage.
[0004] However, the porous high oil-absorbing resins in the prior art mostly have problems such as complex formula, high cost, low oil absorption ratio, poor oil retention, poor oil absorption reversibility, slow oil absorption rate, etc., so it is difficult to meet the requirements of jet fuel treatment.

preparation Embodiment 1

[0045] Add 3 g of the dispersant methylcellulose into 450 g of hot water at about 80°C, stir until completely dissolved, and cool to room temperature. Then it was added into a four-neck flask equipped with a stirrer, a reflux condenser and a thermometer. Then polymerize monomer styrene and lauryl acrylate (molar ratio is 1: 4) altogether 100g, total 1g of initiator sodium persulfate, total 3g of crosslinking agent divinylbenzene and porogen butyl acetate 157 g was added therein and stirred evenly, and nitrogen gas was passed for about 15 minutes at the same time, and the air in the reactor was removed to ensure that the suspension polymerization reaction was carried out under a nitrogen atmosphere. Under stirring, the reaction system was heated to 77.5° C. for suspension polymerization for 6.5 hours, and then the reaction system was heated to 95° C. for 1 hour of aging reaction. With stirring, the product was cooled to room temperature and filtered. The obtained product was ...

Abstract

The invention relates to a porous high oil absorption resin and a preparation method thereof. The preparation method reasonably proportions raw materials and performs suspension polymerization on the proportioned raw materials to prepare the porous high oil absorption resin, and comprises steps of dispersing, mixing, charging, suspension polymerization, extracting and conventional post-processing. The porous high oil absorption resin has high oil absorptivity, particularly for jet fuel.

Description

technical field [0001] The invention belongs to the field of macromolecule synthesis, and in particular relates to a porous super oil-absorbing resin prepared by suspension polymerization using styrene and alkyl acrylate as polymerization monomers and a preparation method thereof. Background technique [0002] In recent years, with the deepening of oil exploration and other developments, the environmental pollution caused by oil leakage and the damage to water resources caused by oily wastewater and waste liquid have become increasingly serious, which has seriously affected human life. Therefore, it is urgent to develop excellent oil-absorbing materials to deal with the severe oil pollution problem. [0003] Super oil-absorbing resin is a low-crosslinked polymer composed of lipophilic monomers. The molecules have a three-dimensional cross-linked network structure, and there are certain micropores inside, which can swell dozens of times of oil. It can be mainly divided into...
