Water-soluble compound fertilizer anti-caking agent and method for preparing same

Abstract

The invention discloses a water-soluble compound fertilizer anti-caking agent and a method for preparing the same. The water-soluble compound fertilizer anti-caking agent comprises, by weight, 85-95 parts of polymeric surfactants, 10-15 parts of fatty acid derivatives and 0.5-5 parts of poly-carbon alcohol. The method includes adding the polymeric surfactants into reaction kettles and heating thepolymeric surfactants until the temperatures of the polymeric surfactants reach 110-120 DEG C; proportionally adding the poly-carbon alcohol into the reaction kettles and preserving heat for 20 minutes; adding the fatty acid derivatives into the reaction kettles and keeping the temperatures of 65-70 DEG C unchanged under the control; feeding products into high-speed stirring and emulsifying equipment, and stirring the products at the high speeds for 30 minutes; sufficiently emulsifying the products and then discharging the water-soluble compound fertilizer anti-caking agent which is a finishedproduct. The water-soluble compound fertilizer anti-caking agent and the method have the advantages that the water-soluble compound fertilizer anti-caking agent is high in water dissolution speed, isfree of residues after being dissolved, is convenient without being heated when used, is environmentally friendly and is free of pollution, and good anti-caking effects can be realized by the water-soluble compound fertilizer anti-caking agent.

Description

technical field [0001] The invention relates to a water-soluble composite fertilizer anticaking agent and a preparation method thereof. Background technique [0002] Fully water-soluble compound fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be applied to Facility agriculture such as drip irrigation realizes the integration of water and fertilizer, and achieves the efficiency of saving water, fertilizer and labor. Because the fully water-soluble compound fertilizer has the characteristics of simple use method and convenient use, it has developed rapidly in our country in recent years. However, in order to achieve high nitrogen, high potassium and full water solubility of fully water-soluble compound fertilizers, the raw materials generally include urea, ammonium phospha...

AI Technical Summary

Problems solved by technology

However, in order to achieve high nitrogen, high potassium and full water solubility of fully water-soluble compound fertilizers, the raw materials generally include urea, ammonium phosphate, ammonium nitrate, ammonium nitrate phosphorus, potassium chloride, potassium sulfate, etc. These raw materials have different degrees of hygroscopicity. The hygroscopicity will change after the raw materials are mixed. Improper selection of raw materials will reduce the hygroscopic point and enhance the hygroscopicity, which will cause the product to agglomerate easily during storage.

[0003] Although the traditional anti-coagulation agent can play an anti-coagulation effect, it will produce insoluble matter after the water-soluble compound fertilizer is dissolved, especially when the nozzle is blocked during drip irrigation, which affects the use of users.
