Production method for polystyrene multi-component copolymerization ion exchange resin for treating phenolic wastewater

Abstract

The invention discloses a production method for polystyrene multi-component copolymerization ion exchange resin for treating phenolic wastewater. The method comprises the specific steps that a water phase and an oil phase are prepared, composite resin microspheres are prepared, and ion exchange resin is synthesized, wherein a resin microsphere framework is formed by cross-linking of styrene, methyl methacrylate and vinyl trimethoxy silane. The polystyrene multi-component copolymerization ion exchange resin has good high-temperature resistance and chemical-resistance stability, and is wide in application range, high in mechanical strength, good in aperture uniformity, high in ion exchange capacity, especially good in adsorption to phenolic pollutants and suitable for treating phenolic wastewater.

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 treating phenol-containing wastewater. 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 basis. 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 ...

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
