The physical chemical properties such as the content of carboxyl,viscosity and storage period are investigated under different conditions.The main factors are studied which effect the stability of oxidized lazybed starch adhesive.A tentative mechanism of its metamporphose is thus gived.Result shows it is the coordinated effect between oxidized-link and water evaporation that cause the decline of the product's stability,according which an adhesive product with high stability is obtained by adding certain anti-oxidation agent.
