AI Technical Summary

Technical Problem

Existing methods for preventing caking in granular fertilizers are either costly or compromise economic and commercial advantages, and there is a need for an effective anti-caking solution that maintains storage stability without significant manufacturing process changes.

Method used

An anti-caking agent composition comprising an anionic surfactant, a copolymer of styrene and acrylic ester or polyvinyl acetate, and dimethylalkylamine or polyhydric alcohol, which coats fertilizer particles to prevent moisture interaction and caking, exhibiting a synergistic effect.

Benefits of technology

The composition effectively prevents caking of fertilizer components by making the surface hydrophobic and reducing moisture contact, ensuring good storage stability and reduced caking properties while maintaining low manufacturing costs.
