The present invention relates to an acrylic water-soluble polymer emulsion composition for granular urea fertilizer coating, a slow-release granular urea fertilizer coated with the same, and a method for preparing the same, and more specifically, an emulsion polymerization reaction using an acrylic monomer to improve the dissolution rate of the coating fertilizer in an aqueous solution. Acryl-based water-soluble polymer emulsion, which is added to the acryl-based functional cross-linking monomer and silane-based cross-linking agent or mixtures thereof, prepared by coating and heat-treating the emulsion on the granular urea fertilizer, the appropriate crosslinking of the polymer and the water resistance of the polymer is enhanced, The present invention relates to a slow-release granular urea fertilizer having excellent dissolution rate of fertilizer in aqueous solution and a method for producing the same. |
