self crosslinked type polyacrylate salt super absorbent - Production method
P> put the organic solvent, acrylic monomer, emulsifier Span 60, sodium dodecyl sulfonate, 0.021% additive and diethylene glycol into the reactor, and stir to fully mix and emulsify them. In addition, take a separatory funnel, add potassium hydroxide and initiator potassium persulfate into it, shake and mix, put the reactor into a thermostatic tank, fill with nitrogen, stir the reaction liquid, and slowly add potassium persulfate Potassium hydroxide solution, react for 2-3h, after the reaction is over, rest, dump the upper organic solvent, take out the granular polymer, and remove the residual solvent and unreacted monomer under reduced pressure to obtain a water-absorbing resin.
