| titleOfInvention | Contamination-resistant large-capacity macroporous weak-acid resin synthesis method |
| abstract | The invention discloses a contamination-resistant large-capacity macroporous weak-acid resin synthesis method. The synthesis method comprises the steps that an acrylonitrile monomer, a divinyl benzene crosslinking agent, a pore-foaming agent and an initiator are adopted according to a certain proportion to prepare an oil phase, and water, a dispersing agent and NaCI are adopted to prepare a water phase in a polymerization kettle, then the oil phase is added to the water phase, heat release reaction occurs in the polymerization kettle, and the temperature of released heat is as high as 95 DEG C; cooling is performed with prepared saturated salt water, the temperature of the polymerization kettle is kept at 95 DEG C, then heating is performed to reach 100 DEG C, and heat-preservation distillation is performed; after temperature reduction, discharging, washing, drying, screening and cooling, contamination-resistant large-capacity acrylic acid type cation exchange resin white balls are obtained, the white balls are subjected to dissolving and swelling and then are mixed with 60 wt% sulphuric acid to perform hydrolysis reaction, heat preservation is performed for 10 hours, then discharging is performed, the discharge is washed with water to be neutral, alkali regulation is performed to reach pH = 12, and standing is performed for 2 hours; then, the discharge is washed with water to be neutral, acid regulation is performed to reach pH = 2, and standing is performed for 2 hours; the discharge is washed with pure water to be neutral and then is converted into sodium resin by using NaOH with the concentration of 30%, namely the contamination-resistant large-capacity macroporous weak-acid resin is obtained. |
