Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to solve the defects that the existing anti-caking agents are easy to cause pollution to the soil where the fertilizer is applied and the surrounding environment, and it is difficult to degrade or be absorbed by the crops after acting on the fertilizer, and it is difficult to achieve the use effect. A preparation method of an environment-friendly pasty anti-caking agent. In the invention, two kinds of natural fatty alcohols are mixed and heated, and then reacted with phosphorus pentoxide to prepare mixed fatty alcohol phosphate, and then mixed with soybean oil and stearic acid Zinc and other materials are compounded into a compound material liquid, and then the attapulgite is activated with sulfuric acid solution, and then it is mixed with talcum powder and dried, and then mixed with the compound material liquid to obtain an environmentally friendly paste anti-caking agent. A hydrophobic layer is formed on the surface of the fertilizer, and the attapulgite forms an isolation layer on the hydrophobic layer, which can also effectively absorb the moisture in the fertilizer, further reducing the frequency of the dissolution-crystallization process of the fertilizer salt solution, thereby reducing the agglomeration of the fertilizer. The present invention The prepared environmentally friendly paste anti-caking agent can effectively improve the anti-caking performance of fertilizers, significantly improve the utilization rate of fertilizers, and has good biodegradability, will not pollute the soil and its surrounding environment, and has a good use effect

Abstract

The invention discloses a preparation method of an environment-friendly pasty anti-blocking agent, which belongs to the technical field of preparation of agricultural materials. The preparation method comprises the following steps: firstly mixing and heating two natural fatty alcohol to obtain a mixture I, enabling the mixture I to react with phosphorus pentoxide to obtain mixed fatty alcohol phosphate, compounding the mixed fatty alcohol phosphate with soybean oil, zinc stearate and the like to obtain a material solution, activating attapulgite by using a sulfuric acid solution, mixing, grinding and drying the attapulgite and talcum powder, then mixing with the material solution, thus obtaining the environment-friendly pasty anti-blocking agent. A hydrophobic layer is formed by oil on the surface of fertilizer, the attapulgite forms an isolation layer on the hydrophobic layer, moisture in the fertilizer can also be effectively absorbed, and the frequency of the dissolving-crystallizing process of a fertilizer salt solution can be further reduced, so that the blocking performance of the fertilizer is reduced; and the environment-friendly pasty anti-blocking agent can effectively improve the anti-blocking performance of the fertilizer, can significantly increase the utilization rate of the fertilizer, and is good in biological degradability, free from polluting the soil and peripheral environment, and good in application effect.

Description

technical field [0001] The invention discloses a preparation method of an environment-friendly pasty anti-caking agent, which belongs to the technical field of agricultural material preparation. Background technique [0002] Chemical fertilizers, whether powdered or granular, will agglomerate and lose fluidity under certain conditions, and the phenomenon of forming hard lumps is called fertilizer agglomeration. Fertilizer caking usually occurs during material storage, loading and unloading, and transportation. The main reason for fertilizer agglomeration is water exchange between fertilizer particles, salt dissolution and recrystallization, and salt bridge formation. Fertilizer agglomeration not only affects the appearance of fertilizers, but also reduces its use efficiency. Not only that, serious agglomeration Chemical fertilizers are difficult to break, and some agglomerates are not good for mechanical fertilization. Small pieces are easy to block the nozzle and are not e...
