Abstract

Modified fly ash and acrylic acid were used to synthesize fly ash/sodium polyacrylate superabsorbent polymer through aqueous solution polymerizationin in the study.On water-absorption and capability of the composite,the influences of neutralization degree,polymerization temperature,reaction time and not-treated by static stratification were mainly analyzed by single-factor method.The reaserch result show that: when neutralization degree is 50 %,polymerization temperature is 70 ℃,reaction time is 5 h and static stratification,SAC which is prepared has optimal water-absorption performance.
