Abstract

The invention discloses a production method of a strong-acid triallyl isocyanurate cation exchange resin. Based on the traditional production process, through reasonable matching of a suspending protective agent, a dispersing agent, a pore-foaming agent and a complexing agent, and optimizing processing parameters, the anion exchange resin prepared by the method has the effects of uniform pore distribution and improved exchange capacity. According to the preparation method, the specific surface area of the prepared ion exchange resin is more than 70m<2> / g, the proportion of mesopores larger than 2nm is greater than 50%, the complete exchange capacity reaches 5.5 mmol / g, and the water ratio is 48%.

Description

Technical field [0001] The invention belongs to a method for preparing ion exchange resins, in particular to a method for preparing strong acid triallyl isocyanurate cation exchange resin. Background technique [0002] Anion and cation exchange resins are widely used in water treatment, material purification, concentration, separation, transformation of material ion composition, material decolorization, and catalysts. Although the exchange capacity of the current anion and cation exchange resins has been effectively improved, the pore size distribution is uneven, the proportion of small pores is too large, and the exchange rate is low. Problems such as insufficient exchange capacity cannot meet customer requirements. Summary of the invention [0003] The purpose of the present invention is to provide a method for producing strong acid triallyl isocyanurate-based cation exchange resin. The present invention improves the dispersibility and suspension by improving the water phase, t...
