Abstract

The invention relates to a preparation method of an efficient oil absorption material. According to the method, (perfluorobutyl)ethylene is introduced into polymerization as a comonomer, a long--carbon-chain fluorine-containing monomer is introduced on the basis of isobutyl acrylate and divinylbenzene, and the hydrophobic performance of the long-carbon-chain fluorine-containing monomer allows compatibility of the resin to oil to be improved and allows the oil adsorption and keeping capability to be enhanced. The soft component isobutyl acrylate is introduced into polymerization so as to provide a long-carbon-chain branch structure, thus optimizing the three-dimensional space structure of the resin molecule, enhancing oil molecule capturing capability of the three-dimensional space structure of the resin molecule, and significantly enhancing the comprehensive oil adsorption performance of the resin. Therefore, an acrylic acid series resin with high oil adsorption and high performances is developed. The introduction of the fluorine-containing group enhances the corrosion resistance of the resin skeleton and protects the sphere surface, thus prolongs the service lifetime.

Description

technical field [0001] The invention relates to a method for preparing a resin adsorbent, in particular to a method for preparing an efficient oil-absorbing material. Background technique [0002] Super oil-absorbing resin is a functional polymer material developed rapidly in recent years. These materials have a network structure similar to super-absorbent resin, which can absorb various oily substances. They have fast oil absorption speed, high oil absorption ratio, strong oil retention capacity and Good heat resistance, cold resistance, not easy to age and easy to handle after oil absorption. With the advantages of wide source of raw materials, simple synthesis method and excellent performance, it is a new type of functional polymer material with a prospect of popularization and application. [0003] High oil-absorbing resin is a polymer with a low degree of cross-linking made from lipophilic monomers. It has a three-dimensional cross-linked network structure with certain...
