Embodiment 1

[0012] 0.0168 gram of copper bromide, 0.0748 gram of isophthalic acid are dissolved in 20 milliliters of N,N-dimethylformamide, 0.035 gram of polystyrene microsphere macromolecular initiator, 0.0165 gram of ascorbic acid, 0.5 milliliter of pentaerythritol tetraacrylate Add it to the monomer (5.0 ml of butyl methacrylate, 4.0 ml of methyl methacrylate), and then add it to the reaction bottle repeatedly for nitrogen and deoxygenation twice, and put the reaction bottle into a constant temperature oil bath at 80 degrees Celsius for polymerization . After reacting for 18 hours, the product was washed with hydrobromic acid, filtered with suction, dried, extracted with a Soxhlet extractor for 12 hours, and dried in vacuum to obtain a super oil-absorbing resin.

[0013] The oil absorption ratio of the obtained high oil-absorbing resin to toluene was 21 times.

Embodiment 2

[0015] 0.0061 gram of anhydrous ferric chloride, 0.0299 gram of iminodiacetic acid are dissolved in 20.5 milliliters of N,N-dimethylformamide, 0.075 gram of polystyrene microsphere macromolecular initiator, 0.0180 gram of ascorbic acid, 0.35 milliliter of pentaerythritol Tetraacrylates were added to the monomers (6 ml of butyl methacrylate, 3.8 ml of methyl methacrylate), added to the reaction flask in turn, filled with nitrogen and deoxygenated once, and put the reaction flask into a constant temperature oil bath at 80 degrees Celsius Polymerization. After reacting for 20 hours, the product was washed with concentrated hydrochloric acid, filtered with suction, dried, extracted with a Soxhlet extractor for 18 hours, and dried in vacuum to obtain a high oil-absorbing resin.

[0016] The oil absorption ratio of the obtained high oil-absorbing resin to toluene was 18 times.

Embodiment 3

[0018] 0.0070 gram of anhydrous ferric chloride, 0.0255 gram of iminodiacetic acid are dissolved in 21 milliliters of N,N-dimethylformamide, 0.035 gram of polystyrene microsphere macromolecular initiator, 0.0159 gram of ascorbic acid, 0.45 milliliter of pentaerythritol Tetraacrylates were added to the monomers (6.0 ml butyl methacrylate, 3.8 ml methyl acrylate), added to the reaction bottle in turn, filled with nitrogen and deoxygenated repeatedly for 2 times, and put the reaction bottle into a constant temperature oil bath at 85 degrees Celsius polymerization. After reacting for 15 hours, the product was washed with concentrated hydrochloric acid, filtered with suction, dried, extracted with a Soxhlet extractor for 12 hours, and dried in vacuum to obtain a high oil-absorbing resin.

[0019] The oil absorption ratio of the obtained high oil-absorbing resin to toluene was 12 times.

Abstract

The invention discloses a method for preparing high oil absorption resin, which is characterized by comprising the following steps of: firstly, preparing a polystyrene microsphere macroinitiator modified by chlorosulfonic acid, n-propylamine and sodium hypochlorite; then dissolving a catalyst and a ligand into N,N-dimethylformamide as a solvent; adding the polystyrene microsphere macroinitiator, ascorbic acid as a reductant and tetramethylol methane tetraacrylate as a cross-linking agent into an acrylic monomer; charging nitrogen for deoxidizing; undergoing polymerization reaction for a period of timeat a certain temperature; washing, filtering, drying, extracting by a Soxhlet extractor and vacuum drying to obtain the high oil absorption resin. By dint of the method disclosed by the invention, high oil absorption resin with three-dimensional structure can be obtained, and therefore, the invention has a favorable environment-protection application value.

Description

technical field [0001] The invention relates to a method for preparing a high oil-absorbing resin, in particular to a method for preparing a high oil-absorbing resin based on styrene microspheres, and belongs to the field of functional polymer materials. Background technique [0002] With the development of the industrial economy in today's world, human beings' dependence on energy, especially oil, is becoming more and more important. Oil pollution has seriously affected the ecological environment, especially the recent frequent oil spills. A large amount of leaked crude oil not only caused huge economic losses and a great waste of scarce energy, but also caused unpredictable ecological environmental pollution. [0003] In order to control oil pollution, the most researched at present is the preparation of high oil-absorbing resin containing chemical crosslinking. The traditional preparation methods are suspension polymerization and emulsion polymerization. There are few re...
