Anti-blocking agent of fertilizer

Abstract

The invention relates to an anti-blocking agent of fertilizer. The anti-blocking agent of the fertilizer mainly comprises inorganic components and organic components, wherein the inorganic components comprise the following chemical components: 45%-65% of silicon dioxide (SiO2), 10%-25% of magnesium oxide (MgO), 10%-20% of calcium oxide (CaO), 8%-15% of aluminium sesquioxide (Al2O3) and 6%-12% of iron sesquioxide(Fe2O3); and the percentage content of each organic component in the formula is as follows: 1%-5% of plant animal oil, 1%-5% of C14-C20 alkyl primary amine, 0.5%-1% of C12-C20 alkane sulfonate, 2%-5% of magnesium fatty acid Mg(RCOO)2 and 2%-5% of zinc fatty acid Zn(RCOO)2. The anti-blocking agent of the fertilizer has the advantages of good anti-blocking performance, high added value, capability of solving the problems of macrotrichium and pulverization, less dosage, simple and convenient operation, easy degradation, no dust, environmental protection and wide usable range, and is abundant in necessary nutrient elements of calcium, magnesium, sulphur and the like for crop growth.

Description

technical field [0001] The invention relates to an anti-caking agent for chemical fertilizers, in particular to an anti-caking agent for chemical fertilizers suitable for preventing caking of chlorine-based, nitro-based, urea-based and sulfur-based compound fertilizers, and belongs to the technical field of fertilizer additive production. Background technique [0002] Chemical fertilizers are easy to absorb moisture in the air, and are easy to agglomerate during production and storage. The appearance and quality of chemical fertilizers are affected to a certain extent after agglomeration, and at the same time bring a lot of inconvenience to handling and use. It is necessary to smash the agglomerated fertilizer with hard things to facilitate the absorption of nutrients in the fertilizer. It is very inconvenient to use such fertilizer, and it takes time to break the agglomerated fertilizer, which is time-consuming and labor-intensive. And it is difficult to achieve the effect ...

Problems solved by technology

[0003] At present, the anti-caking agents used in China have the following problems: First, although the imported anti-caking agents are effective, their price is relatively high, which increases the cost of the product; The caking effect is not very good, the price is relatively cheap, and the anti-caking of some chemical fertilizer products cannot meet the production requirements
