Abstract

A carbon nanometer tube ion exchange resin preparation method by utilizing the thermal stability and specific aperture structure of the carbon nano-tube for preparing microporous type thermostable carbon nano-tube ion exchange resin comprises the steps of, stirring and mixing the carbon nano-tube with polymer and initiating agent at specific temperature for a period of time before carrying out the polymerization reaction, employing a delay original position reset polymerization to increase the polymer molecular weight, and employing the method of improving degree of crosslinking to increase the mechanical strength of the ion exchange resin.

Description

technical field [0001] The invention relates to a method for preparing a carbon nanotube ion exchange resin, belonging to the technical field of ion exchange resin preparation. Background technique [0002] The preparation of ion-exchange resins with good thermal stability, reasonable skeleton and pore structure, and low expansion rate has always been the goal that people strive for. Due to material and structure reasons, ordinary acidic cation exchange resins cannot be used for a long time in reactions above 100°C, and ordinary basic anion exchange resins cannot be used in reactions above 50°C for a long time, and the swelling is severe to a large extent The scope of use of the resin is limited. [0003] At present, there are generally two methods for the preparation of high temperature resistant resins in the world: the first method is to improve the thermal stability of the material itself, such as NafionR, NafionXR, Nafion511, NafionXR-500 produced ...
