The Synthesis of Graft Copolymer of Starch with Acrylic Acid and Acrylamide and its Application in Sand-Fixing
An Environmental friendly sand-fixing agent of water-borne polymer(graft copolymer of starch with acrylic acid and acrylamide)was synthesized. The influences of monomer dosage ratio, initiator dosage , the temperature and reaction time on the properties were discussed. The structure, thermal stability and morphology was characterized by IR spectra, TG-DTA and SEM, respectively. With the sand soil as research object, the tolerance of high temperature and compressive strength of the sand-fixing agent were studied preliminarily. The results show that when the mass ratio of acrylic acid to acrylamide is 15:10, the mass content of initiator is 4%, the reaction temperature is 50°C and time is 6h, the product has a good sand fixation performance for practical application.
