Embodiment 1

[0011] Dissolve 0.0030 g of anhydrous ferric chloride, 0.0150 g of iminodiacetic acid into 21 ml of N,N-dimethylformamide, 0.075 g of modified silica gel macroinitiator, 0.01 g of ascorbic acid, and 0.5 ml of pentaerythritol tetra Acrylic acid ester is dissolved in the monomer (5.3 milliliters of butyl methacrylate, 3.8 milliliters of methyl methacrylate), successively add in the reaction bottle and repeatedly fill nitrogen and remove oxygen twice, put the reaction bottle into a constant temperature oil bath of 80 degrees Celsius Polymerization. After reacting for 12 hours, the product was precipitated, 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 adsorption material.

[0012] The obtained high oil-absorbing resin adsorption material has an oil absorption ratio of 23 times to toluene.

Embodiment 2

[0014] Dissolve 0.0030 g of anhydrous ferric chloride, 0.0349 g of iminodiacetic acid into 19 ml of N,N-dimethylformamide, 0.0675 g of modified silica gel macroinitiator, 0.0100 g of ascorbic acid, and 1.7 ml of pentaerythritol tetra Dissolve acrylate in the monomer (5.3 ml of butyl methacrylate, 3.8 ml of methyl methacrylate), sequentially add to the reaction bottle, fill with nitrogen and deoxygenate once, and put the reaction bottle into a constant temperature oil bath at 80 degrees Celsius polymerization. After reacting for 15 hours, the product was precipitated, washed with concentrated hydrochloric acid, filtered with suction, dried, extracted with a Soxhlet extractor for 16 hours, and dried in vacuum to obtain a high oil-absorbing resin adsorption material.

[0015] The obtained high oil-absorbing resin adsorption material has an oil absorption rate of 19 times for toluene.

Embodiment 3

[0017] 0.0052 g of anhydrous ferric chloride, 0.0479 g of iminodiacetic acid were dissolved in 18 ml of N, N-dimethylformamide, 0.0900 g of modified silica gel macroinitiator, 0.0159 g of ascorbic acid, 0.7 ml of pentaerythritol tetra Acrylate is dissolved in the monomer (6.4 milliliters of butyl methacrylate, 4.5 milliliters of methyl methacrylate), successively added to the reaction bottle and repeatedly filled with nitrogen and deoxygenated twice, and put the reaction bottle into a constant temperature oil bath at 85 degrees Celsius Polymerization. After reacting for 12 hours, the product was precipitated, washed with concentrated hydrochloric acid, filtered with suction, dried, extracted with a Soxhlet extractor for 24 hours, and dried in vacuum to obtain a high oil-absorbing resin adsorption material.

[0018] The obtained high oil-absorbing resin adsorption material has an oil absorption rate of 17 times for toluene.

Abstract

The invention discloses a method for preparing a high oil absorption resin adsorption material, which is characterized by comprising the following steps of: synthesizing a silica gel macroinitiator modified by a silane coupling agent; dissolving a catalyst and a ligand in a solvent, dissolving the modified silica gel macroinitiator, a reducing agent and a cross-linking agent in a monomer, introducing nitrogen to remove oxygen, and performing atom transfer radical polymerization initiated by an electron transfer regenerated catalyst at certain temperature for a certain period; and precipitating products, washing with concentrated hydrochloric acid, suction filtering, drying, extracting by using a Soxhlet extractor, and performing vacuum drying to obtain the adsorption material. The high oil absorption resin adsorption material with a three-dimensional structure can be prepared by the method, and can be applied in the fields such as environmental protection and the like.

Description

technical field [0001] The invention relates to a preparation method of a high oil-absorbing resin adsorption material, which belongs to the field of functional polymer materials. Background technique [0002] High oil-absorbing resin adsorption materials have been extensively researched, developed and applied in recent years because of their ability to adsorb a variety of oil products, their large oil absorption ratio and fast oil absorption rate, and their prospects are very broad. There are many substances for preparing super oil-absorbing resin adsorption materials, and the traditional adsorption materials are mostly porous materials, such as activated carbon, silica gel, cellulose, etc. However, the oil absorption rate of this kind of material is low, and the oil retention capacity is poor. [0003] Graft modification of polymers is a simple and effective method to improve the properties of polymer materials, which expands the application fields of polymers. By modify...
