Study on Synthesis of Superabsorbent and Water Absorbency

Abstract:

Article Preview

A technical condition for the reaction of preparing superabsorbent by orthogonal test was investigated. Test results were as follows: reaction temperature was 30 °C, reaction time was 2 h, monomer ratio is 0.045, monomer was 12 g, neutralization degree was 90%, initiator concentration was 0.167 wt% and crosslinker concentration was 0.0125 wt%. The maximum of distilled water absorbency was 699 times, the maximum of 0.9% saline water absorbency was 70 times. Analysis from FTIR and SEM showed that starch grafting with acrylic acid and acrylamide was successful, while a three-dimensional network structure was formed in superabsorbent.
