| titleOfInvention | Preparation method of porous sodium acrylate super absorbent resin |
| abstract | The invention relates to a preparation method of a porous sodium acrylate super absorbent resin. The preparation method comprises the following steps: an aqueous solution containing 30 to 45 wt% of acrylic acid monomers with a neutralization rate of 60 to 90 mole%, a cross linking agent, a porogenic agent, and a polymerization initiator are polymerized together under nitrogen protection; and porous particles are prepared through preparing granulums with diameters of 2 to 10 mm from hydrogel prepared through polymerization, and adding the surface cross linking agent and an inorganic filler to carry out surface processing. The preparation method of the invention allows continuous production to be realized, productivity to be improved, manpower to be decreased, a problem of slow imbibition to be solved, drying period to be substantially decreased, product performances to be substantially improved, the qualified rate of products to be high, reaction to be mild, and three wastes to be less. |
