Abstract

The invention belongs to the technical field of agricultural chemical fertilizer production, and particularly relates to an anti-caking agent for a compound fertilizer (blended fertilizer) and a preparation method thereof. The full-biodegradable anti-caking agent for the compound fertilizer / blended fertilizer is characterized by comprising the following components in percentage by mass: 84.5 to 90 percent of fatty acid, 2 to 3 percent of anionic surfactant, 0.2 to 1 percent of cationic surfactant, 0.5 to 1.5 percent of polyether macromolecular surfactant and 5 to 10 percent of aliphatic ester. The prepared anti-caking agent can be fully degraded under a natural environment, and has good anti-caking effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizer production, and in particular relates to an anti-caking agent for compound fertilizer (compound fertilizer) and a preparation method thereof. Background technique [0002] The caking problem of compound fertilizer (compound fertilizer) is a problem that the chemical fertilizer industry has been committed to solving for a long time. Agglomeration seriously affects fertilizer efficiency, and brings many difficulties to storage, transportation and use. Compound fertilizer (compound fertilizer) is mainly based on moisture absorption, liquid on the surface of particles, water evaporation and crystallization, particles to bridging circulating water, and agglomeration after a certain period of time. It is generally believed that particle size, particle strength, hygroscopicity, water content, and external environment are the main factors affecting caking. [0003] In order to p...
