Abstract: A novel polyer attapulgite superabsorbent composite was synthesized by aqueous solution polymerization,using acidified attapuigite micropowder and acrylamide as raw materials,N-N'methylene-bisacrylamide as a crosslinker and potassium persulphate as an initiator.Attapulgite was based on polymer materials was treated by H2SO4 aqueous solution,water absorption,water retention,the pH value,XRD and SEM analysis were studied,the results show that the attapulgite is based on polymer materials have the better water absorption,water retention,adsorption performance and the change of the pH value has a better influence which is modified by 4 mol/L H2SO4,XRD and SEM show polymer sand-fixation material base on attapulgite that 3 mol/L and 4 mol/L H2SO4 aqueous solution treated have better adsorption properties.The results show that it is necessary to strengthen the research of acid activation attapulgite based on polymer materials,so it is expected to prepare a new type of environmentally friendly composite superabsorbent sand-fixation material based on attapulgite.
