Anti-caking agent for fertilizer and preparation method thereof

Abstract

The invention relates to an anti-caking agent for fertilizer and a preparation method thereof. The anti-caking agent comprises the following components in percentage by weight: 5-10% of hydrogenized bovine fatty amine, 15-25% of solid paraffin, 5-15% of stearic acid and 50-75% of oil. The method comprises the following steps: adding the hydrogenized bovine fatty amine, the solid paraffin and the stearic acid to a pulverizer according to the percentage by weight for pulverizing to 80-100 meshes; and then, dispersing the pulverized particles into the oil while being stirred to prepare the anti-caking agent for the fertilizer. The invention has the advantages that high melting-point matters such as the paraffin, the hydrogenized bovine fatty amine, the stearic acid and the like need not to be molten into a liquid state; after the high melting-point matters such as the paraffin, the hydrogenized bovine fatty amine, the stearic acid and the like are uniformly dispersed in the oil, the high melting-point matters have good flowability, heating again for melting in the canning process and in the using process are omitted; and all the steps of the invention are carried out at normal temperature.

Description

technical field [0001] The invention relates to an anti-caking agent for chemical fertilizers and a preparation method thereof. Background technique [0002] The current method for preparing the fertilizer anti-caking agent is to incorporate high melting point substances such as paraffin and fatty amine into the oil body. The fluidity of the paste is very poor, and it needs to be heated again to increase its fluidity during canning. In use, it needs to be further heated and melted, that is, it has to go through three melting processes, resulting in a waste of resources and energy. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a chemical fertilizer anti-caking agent and a preparation method thereof. The production process of the method is simple, does not require a heating and melting process, and the produced chemical fertilizer anti-caking agent has good fluidity, can be easily used, and does not require heating and melting. It can...

Problems solved by technology

The fluidity of the paste is very poor, and it needs to be heated again to increase its fluidity when filling the can.

When in use, it needs to be further heated and melted, that is, it has to go through three melting processes, resulting in a waste of resources and energy.
