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

Abstract

The invention discloses a production method of a nano cellulose composite polystyrene multipolymer cation exchange resin. The method comprises the following steps: preparing a water phase and an oil phase, preparing composite resin microspheres and synthesizing the ion exchange resin, wherein the resin microsphere framework is prepared by crosslinking styrene, methyl methacrylate and vinyltrimethoxysilane. The polystyrene multipolymer cation exchange resin has the advantages of favorable high-temperature resistance, favorable chemical resistance stability, wide applicability, high mechanical strength, favorable pore size uniformity and high ion exchange capacity, especially has favorable adsorbability for heavy metal pollutants, and is suitable for treatment of heavy metal 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 nano-cellulose composite polystyrene multi-component copolymerized cation exchange resin. 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 easy-to-obtain ra...
