preparation Embodiment 1

[0021] At room temperature, add styrene and lauryl acrylate (molar ratio is 1: 4) altogether 100g in the four-necked flask that agitator, reflux condenser, thermometer are equipped with, totally 5g of emulsifying agent Tween 60, initiator A total of 0.6g of sodium persulfate and 350g of deionized water. Stir rapidly for about 5 to 30 minutes to form a stable emulsion.

[0022] Nitrogen was passed into the reaction flask for about 5 to 15 minutes to remove the air therein so that the reaction was carried out under the protection of nitrogen. Under stirring, the reaction system was heated to 68° C. for emulsion polymerization for 6.5 hours, and then the reaction system was heated to 90° C. for aging reaction for 2 hours. With stirring, the product was cooled to room temperature and filtered to obtain the product.

preparation Embodiment 2 to 8

[0024] The oil-absorbing resin was prepared in the same manner as in Example 1, except that the test conditions listed in Table 1 below were adjusted accordingly.

Abstract

The invention relates to a preparation method of high oil-absorption resin, comprising the following steps of: (a) adding a polymer monomer mixture, water, an emulsifier and an initiator in a reactor, and stirring quickly to form a stable emulsion; (b) introducing nitrogen for protection; (c) heating a reaction system to 50 to 78 DEG C while stirring so as to perform emulsion polymerization reaction for 3.5 to 7.5 hours, and then continuing to heat the reaction system to 80 to 100 DEG C so as to perform curing reaction for 0.5 to 2.5 hours; and (d) carrying out conventional post-processing, cooling and filtering to obtain the product. The high oil-absorption resin prepared by the method has high oil-absorption ratio in allusion to jet fuel.

Description

technical field [0001] The invention belongs to the field of macromolecule synthesis, and in particular relates to a method for preparing super oil-absorbing resin through emulsion polymerization by using styrene and alkyl acrylate as polymerization monomers. 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. Through the solvation of the intramolecular lipophilic segment and the oil molecule, the pol...
