Problems solved by technology

[0005] However, during the production and storage of water-soluble fertilizers, due to the characteristics of their raw materials, water-soluble fertilizers are more likely to absorb moisture and agglomerate, which brings difficulties to sales and use.
The currently used anti-caking method is to spray mineral oil or a mixture of mineral oil and vegetable oil on the outer surface of the water-soluble fertilizer; the disadvantage of this method is that the mineral oil has strong hydrophobicity when the water-soluble fertilizer is dissolved. Water immiscibility slows down the disintegration and dissolution of water-soluble fertilizers, and these mineral oils float on the water surface and are difficult to degrade in the field after spraying, which has adverse effects from the perspective of use and environmental protection; in addition , Some mineral oils have a high freezing point and form a solid oil block in water, which will block the nozzle during drip irrigation and spraying, which will bring trouble to the use

Abstract

The invention discloses a microemulsion type water-soluble fertilizer anti-blocking agent and a preparation method thereof. The anti-blocking agent comprises the raw materials of a surfactant and anti-blocking oil, wherein the surfactant comprises one or a plurality of anionic surfactant, nonionic surfactant and zwitterionic surfactant; the HLB of the surfactant is 7-14; the anti-blocking oil comprises one or a plurality of vegetable oil, modified vegetable oil, vegetable wax and aliphatic ester. The preparation method of the anti-blocking agent comprises the step of preparing basic anti-blocking oil and the step of preparing an anti-blocking agent. The prepared microemulsion type water-soluble fertilizer anti-blocking agent is good in anti-blocking effect; after a water-soluble fertilizerwrapped with the prepared microemulsion type water-soluble fertilizer anti-blocking agent is dissolved in water, the microemulsion type water-soluble fertilizer anti-blocking agent can be completelydissolved in water together with the water-soluble fertilizer; floating oil and precipitate are avoided; the solution is uniform in phase and is smoothly and uniformly sprayed during use; pollution precipitating in a farmland is avoided; and the soil and the soil texture cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of anti-caking of compound water-soluble fertilizers, in particular to a microemulsion anti-caking agent for water-soluble fertilizers and a preparation method thereof. Background technique [0002] Water-soluble fertilizers refer to compound fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid and alginic acid that can be completely dissolved in water. There are solid water-soluble fertilizers and liquid water-soluble fertilizers in terms of form. Two types; in terms of nutrient content, there are water-soluble fertilizers with large elements, water-soluble fertilizers with medium elements, water-soluble fertilizers with trace elements, water-soluble fertilizers containing amino acids, water-soluble fertilizers containing humic acids, organic water-soluble fertilizers, etc. Although water-soluble fertilizer has just started in China, people in t...
