Embodiment 1

[0025] Dissolve 3.129 grams of poly-n-butyl methacrylate in 3.129 grams of n-butyl methacrylate, then add 1.252 grams of Span 80 and 0.275 grams of divinylbenzene into n-butyl methacrylate, stir evenly, and pass Nitrogen for 40 minutes to obtain an oily phase. Take 32 grams of deionized water as the water phase, and add the water phase to the oil phase dropwise at a constant speed at a stirring speed of 1000 rpm. After the dropwise addition, 0.082 g of ammonium persulfate (0.36 mmol) and 0.037 g of sodium bisulfite (0.356 mmol) were weighed to prepare an aqueous solution, added to the above emulsion, and continued to stir for 20 minutes until the emulsion was stable. React at 40 degrees Celsius for 24 hours, extract the product through a Soxhlet extractor for more than 12 hours, and dry it in vacuum to obtain a fast high oil-absorbing resin.

Abstract

The invention relates to a method for preparing a rapid high oil absorption resin by using a macromolecule pore-foaming agent. The method comprises the following steps: 1) firstly, dissolving the macromolecule pore-foaming agent in a monomer, adding an emulsifier and a cross-linking agent in the monomer, stirring uniformly, introducing nitrogen to obtain an oil phase; 2) taking a certain amount of deionized water as a water phase, dropwise adding the water phase to the oil phase at a constant speed to obtain emulsion after dropwise adding, adding the configured oxidation reduction initiation system in the emulsion, stirring continuously until the emulsion is stable, and finally polymerizing the emulsion to obtain oil absorption resin; and 3) extracting the oil absorption resin through a soxhlet extractor and carrying out vacuum drying to obtain rapid high oil absorption resin. In comparison with the prior art, the resin has higher oil absorption volume and oil absorption rate, so that the resin has good effect when an emergent oil product pollution event needs to be handled urgently. The resin has good reuse performance, so that the cost is lowered.

Description

technical field [0001] The invention relates to a method for preparing a rapid high oil-absorbing resin by using a macromolecule porogen, and belongs to the field of functional polymer materials. Background technique [0002] With the rapid development of my country's economy, sudden oil pollution incidents are increasing day by day. Such incidents often require rapid emergency treatment in a short period of time, so it is particularly important to have fast and efficient oil-absorbing resins. [0003] Super oil-absorbing resin is a resin with three-dimensional network chemical crosslinking structure, which has developed rapidly in recent years. Most of the oil-absorbing resins reported so far have a very slow oil absorption rate, and it usually takes several hours to reach the saturated oil absorption. For some porosity fast oil-absorbing resins, it also takes one or two hours to reach the saturated oil absorption. Most of these resins use organic solvents such as ethyl ac...
