▎ 摘  要

NOVELTY - Strongly basic graphene composite ion exchange resin material comprises matrix and graphene in the composite ion exchange resin, which are combined in the form of a covalent bond. USE - Strongly basic graphene composite ion exchange resin material. ADVANTAGE - The strongly basic graphene composite ion exchange resin material improves the thermal decomposition temperature and anti-swelling performance of the composite ion exchange resin very well, and used in the industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing strongly basic graphene composite ion exchange resin material, which involves: (A) obtaining graphene carboxylate; (B) adding graphene carboxylate solution to the phase transfer catalyst and using styrene derivative to carry out the reaction; washing, filtering, and drying to obtain graphene-styrene derivative compound, where graphene-styrene derivative compound is a polymerization monomer, comonomer, initiator, and polymerization agent are mixed to perform a polymerization reaction, washed, filtered, dried, and sieved, to collect composite resin microspheres; and (C) subjecting compound resin microspheres to chloromethylation, amination, and transformation to obtain the strongly basic graphene composite ion exchange resin material.
