Powdery compound fertilizer anti-caking agent and preparation method therefor

Abstract

The invention relates to a powdery compound fertilizer anti-caking agent and a preparation method therefor. The powdery compound fertilizer anti-caking agent comprises the following components in percentage by weight: 85-90% of inorganic powder and 10-15% of modifiers. The inorganic powder is nepheline powder, and the modifiers are sodium oleate. The preparation method for the compound fertilizer anti-caking agent comprises the following steps: adding inorganic powder of 600-1200 meshes and modifiers into powder modifying equipment, controlling the temperature to be 60-70 DEG C, stirring the mixture for 10-20 minutes, and cooling down the mixture to obtain the powdery compound fertilizer anti-caking agent. The powdery compound fertilizer anti-caking agent has the following advantages: low costs; convenient use and addition, thereby facilitating popularization and use; no pollution to human bodies and lands, thereby facilitating environmental protection; and good anti-caking effects, thereby ensuring that fertilizer will not be caked in 6-8 months.

Description

technical field [0001] The invention relates to an anti-caking agent, in particular to a powder compound fertilizer anti-caking agent and a preparation method thereof. Background technique [0002] At present, the main problem of compound fertilizer production in our country is that the product is easy to agglomerate, which makes it difficult for farmers to use it and seriously affects the product quality of production enterprises. Enterprises have to use various anti-caking agents to achieve the purpose of anti-caking. In order to solve the caking problem of compound fertilizers, various fertilizer companies and scientific research institutes have conducted in-depth research on this subject, and have developed targeted anti-caking agents for different types of fertilizers. Our country produces tens of millions of tons of compound fertilizers every year, most of which use oil-soluble anti-caking agents, which consume a large amount of mineral oil every year, with high usage ...

Problems solved by technology

Our country produces tens of millions of tons of compound fertilizers every year, most of which use oil-soluble anti-caking agents, which consume a large amount of mineral oil every year, with high usage costs and serious environmental pollution; although there are some powder anti-caking agents, most Use talc, diatomite as powder, alkylamine, alkyl sulfonate, etc. as powder, but there are several disadvantages: high cost, complicated adding operation process, poor anti-caking effect
