Technology process investigation of superabsorbent resin by inverse suspension polymerization
摘要
Abstract
To solve the problem of low repeatability and absorbing rate in the inverse suspension polymerization, the poly (acrylic acid-acrylamide) superabsorbent copolymer was synthesized through inverse suspension polymerizationt using cyclohexane as the continuous phase, span80 as the suspension stabilizer, N,N-methylene bis-acrylamide and persulfate as the corss-linking agent and the initiator, respectively. The effects of cross-linking agent, dispersing agent, the agitation speed and reaction temperature on the water absorbency and particle size of super absorbent resin were studied. The results show that the maximum absorbency of sodium acrylate-acrylamide copolymer reaches 584 g/g and 148 g/g in distilled water and in NaCl (0. 9%) aqueous solution respectively when the concentrations of crosslinker is 0. 105% of the monomer's, the concentrations of dispersant is 6 % of the monomer's, the neutralization degree is 70%, the ratio of oil and water is 2. 0:1, the reaction temperature is 70 - 74 ℃ , and the particle size of the resin is 0. 1 mm.关键词
