Beschreibung
Zusammenfassung:	The invention belongs to the technical field of adhesive and particularly discloses a method for preparing starch adhesive for granulation of a carbon-based slow release compound fertilizer. The method comprises successively adding an appropriate amount of 10% of sodium hydroxide, 30% of hydrogen peroxide and 6% of ferrous sulfate in starch slurry to oxidize the starch slurry into orange starch slurry, adding an appropriate amount of 10% of sodium hydroxide in the orange starch slurry to perform gelatinization, finally adding borax to perform cross-linking and adding stabilizer, and performing dilution to obtain the starch adhesive. An appropriate amount of sodium hydroxide is respectively added at the oxidation stage and the gelatinization stage; by changing the adding sequence of sodium hydroxide, hydrogen peroxide and ferrous sulfate in the oxidization process, the starch slurry is oxidized more quickly and better, and the viscosity and stability of the starch slurry are improved.
