Embodiment 1

[0026] 20g of octadecyl mercaptan is surface-treated to 75g of zinc oxide powder, and the particle size range of zinc oxide is 50nm to obtain a solvent-free nanoparticle fluid of zinc oxide; In the zinc oxide solvent-free nanoparticle fluid, the ultrasonic stirring time is 1h, the ultrasonic power is 2000W, and the stirring rate is 1200r / min, and the zinc oxide solvent-free fluid coating agent is prepared. The prepared zinc oxide solvent-free fluid coating agent has good fluidity under low temperature conditions, and will not delaminate or sink to the bottom after being stored at normal temperature (25° C.) for 6 months. Coating the granular fertilizer has a good anti-knot effect, and its anti-knot pressure test data shows that it is less than 20N.

Embodiment 2

[0028] 18g of octadecyl mercaptan is used for surface treatment of 77g of zinc oxide powder, the particle size range of zinc oxide is 55nm, and a solvent-free nanoparticle fluid of zinc oxide is obtained. Then add 5g of ester-based quaternary ammonium salt to 95g of zinc oxide solvent-free nanoparticle fluid prepared above, ultrasonically stir for 1h, ultrasonic power 2000W, stirring speed 1200r / min, to prepare zinc oxide solvent-free fluid coating agent. The prepared zinc oxide solvent-free fluid coating agent has good fluidity under low temperature conditions, and will not delaminate or sink to the bottom after being stored at normal temperature (25° C.) for 6 months. Coating the granular fertilizer has a good anti-knot effect, and the anti-knot pressure test data shows that it is less than 25N.

Embodiment 3

[0030] 20g of octadecyl mercaptan is used for surface treatment of 75g of copper oxide powder, the particle size range of copper oxide is 50nm, and a solvent-free nanoparticle fluid of copper oxide is obtained. Then add 5g of ester quaternary ammonium salt to 95g of copper oxide solvent-free nanoparticle fluid prepared above, ultrasonically stir for 1h, ultrasonic power 2000W, stirring speed 1200r / min, to prepare copper oxide solvent-free fluid coating agent. The prepared copper oxide solvent-free fluid coating agent has good fluidity under low temperature conditions, and will not delaminate or sink to the bottom when stored at normal temperature (25° C.) for 6 months. Coating the granular fertilizer has a good anti-caking effect, and its anti-caking pressure test data shows that it is less than 27N.

Abstract

The invention relates to a solvent-free fluid wrapping agent and a preparation method thereof, the solvent-free fluid wrapping agent is composed of 73.5-93.5% of medium trace element-containing nutrient substance, 0.5-5% of ester quaternary ammonium salt and 5.5-24.5% of treating agent, and the medium trace element-containing nutrient substance is solvent-free fluid containing medium trace elementsubstance. The preparation method comprises the following steps: firstly, carrying out surface treatment on medium trace element-containing nutrient substance nanoparticles by using a treatment agentto obtain medium trace element-containing solvent-free nanofluid; and then adding the ester quaternary ammonium salt into the solvent-free nanofluid containing the medium trace element nutrient substances for ultrasonic dispersion, and carrying out ultrasonic stirring for 1-2h at the ultrasonic power of 2000-2500W and the stirring speed of 1200-1600r/min to obtain the solvent-free fluid wrappingagent. Nutrient components in the fluid wrapping agent meet medium and trace elements required by crops in the whole growth period, the crop yield is increased, the crop quality is improved, and meanwhile the product has good anti-caking and dust-proof effects; the low-temperature fluidity is good, and the phenomena of layering and sinking to the bottom are avoided in the long-term storage process.

Description

technical field [0001] The invention relates to a solvent-free fluid coating agent and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] For Chinese people, the quality of agricultural products has seriously declined, and even has a toxic effect on people, which is a great risk to human health. According to the long-term research of the International Sulfur-Zinc Association, the key factor that can affect food production and quality is not the use of macronutrients, but the lack of medium and trace elements. Micronutrient fertilizers, but these fertilizers either cannot solve the problem of uniform distribution of nutrient elements in the soil, or the production process is complicated and the cost is high; [0003] Dust is formed during storage and transport of fertilizer granules. Dust formation is mainly caused by mechanical abrasion caused by the movement of fertilizer particles. Other processes that lead to th...
