Attapulgite clay /xanthan gum-g-acrylic organic-inorganic composite super absorbent resin was prepared by solution polymerisation. The influence factors of synthesising composite super absorbent resin such as the monomer concentration of acrylic acid, initiator amount, degree of neutralization of acrylic acid, amount of AC, amount of crosslinking agent and polymerization temperature were studied .Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were used on characterization of the compound super absorbent resin. The results showed that: The poly-acrylic acid molecules linked to the molecular chain of xanthan gum through graft co-polymerisation, AC and the copolymer occurred organic-inorganic composite, the preparation of attapulgite clay/xanthan gum-g-acrylic acid super absorbent absorbent resin has good properties of water absorption and salt resistance,the retention performance was inproved in high temperature, percent grafting up to 137.2%grafting efficiency up to 83.6%,and the highest water absorption up to 896ｇ/ｇ-1, normal saline is up to 126.3ｇ/ｇ-1.
