Production method of polystyrene multi-component copolymerization ion exchange resin for removing anionic dye

Abstract

The invention discloses a production method of polystyrene multi-component copolymerization ion exchange resin for removing anionic dye. The method comprises the specific steps of preparation of a water phase and an oil phase, preparation of composite resin microspheres and synthesis of the ion exchange resin, wherein a resin microsphere framework is prepared by crosslinking styrene, methyl methacrylate and vinyl trimethoxy silane. The polystyrene multi-component copolymerization ion exchange resin has the good high temperature resistance and chemical stability resistance and is wide in application range, high in mechanical strength, good in pore size uniformity, high in ion exchange capacity, especially good in adsorptive property on anionic dye contaminants and suitable for treatment of wastewater containing the anionic dye.

Description

technical field [0001] The invention relates to a production method of an ion exchange resin, in particular to a production method of a polystyrene multi-component copolymerization ion exchange resin for removing anionic dyes. Background technique [0002] Ion exchange resin is an important class of adsorption and separation materials. It is a porous spongy solid polymer substance in structure. Each resin particle is composed of a cross-linked network skeleton with a three-dimensional three-dimensional structure, and many movable particles are connected to the skeleton. functional base. It is insoluble in general acid-base solutions and organic solvents, and can be used in various fields such as water treatment, food, pharmaceutical, petrochemical and environmental protection, and is playing an increasingly important role in modern industry. [0003] At present, the most widely used ion exchange resin is polystyrene-based resin, which has the advantages of easy-to-obtain ra...

Problems solved by technology

However, this type of resin has low thermal stability and is greatly affected by the use temperature, which limits its application range. It also has poor chemical stability, poor mechanical strength, and especially poor compression resistance, which also affects its service life. , so it is necessary to improve its comprehensive performance

CN201310172597 introduces the copolymerization of long-chain flexible monomer octadecyl methacrylate and styrene, thereby improving the compressive strength of ion exchange resin microspheres, but this method can only improve the compressive performance of polystyrene resin, and cannot comprehensively improve Its uniformity, thermal stability, chemical stability and other comprehensive properties are difficult to meet the current demand for higher quality ion exchange resins, and its application range is limited
