Abstract

The invention discloses a preparation method of an anti-caking agent for fertilizer, belonging to the technical field of chemical fertilizer production. The preparation method comprises the steps of sequentially weighing 30-40 parts by weight of modified paraffin, 20-30 parts of additives, 8-15 parts of humic acid and 5-10 parts of an adhesive; mixing the modified paraffin with the additives in amixer, adding the humic acid and the adhesive into the mixer, stirring and mixing for 50-60min under the conditions that the temperature is 30-40 DEG C and the rotating speed is 280-380r / min, then carrying out vacuum drying to obtain the anti-caking agent for the fertilizer. The anti-caking agent for the fertilizer has excellent anti-caking property.

Description

technical field [0001] The invention discloses a preparation method of an anti-caking agent for fertilizer, which belongs to the technical field of fertilizer production. Background technique [0002] With the rapid development of economy and urbanization and the increase of population, people's demand for crops is increasing, so it is required that crops have a higher yield to meet people's growing needs. The addition of chemical fertilizers has attracted increasing attention as a way to increase crop yields. Chemical fertilizers are mostly made into granular fertilizers, which can reduce the hygroscopicity of fertilizers, reduce environmental pollution, and facilitate application. [0003] However, all fertilizers have agglomeration to varying degrees, which will affect their properties and performance. Agglomeration not only destroys the free-flowing state of the product, but also often needs to be crushed during use. Therefore, whether the fertilizer is agglomerated or ...
