Thus, more and more scholars hydrogels was studied more and more attention, especially for the preparation process in different conditions on the final product properties for hydrogel new product development more and more important. Ontology is to starch (st), acrylic acid (AA) and acrylamide (AM) as raw materials, N, n - methylene bis acrylamide (MBA) as crosslinking agent, potassium persulfate as initiator, the traditional mixing of preparing starch (st) acrylate (AA) / acrylamide (AM) semi interpenetrating network hydrogel as an example, which starch content, preparation of AA in the process of neutralization degree, crosslinking agent content and AA / am pre poly body in AA and am ratio for the four of starch based hydrogels water absorption, water retention effect. According to the experimental group, the composite water absorption rate of the sample is 210g/g-1, the best water absorption rate is acrylic / acrylamide ratio is 1:1, and the heat stable environment is the crosslinking agent 0.0182g. At the same time, with the same
