Fertilizer anti-caking wrapping agent and preparation method thereof

Abstract

The invention discloses a fertilizer anti-caking wrapping agent which comprises the following components in parts by weight: 25-45 parts of liquid wax oil, 10-20 parts of temperature-resistant black,28-48 parts of fatty acid derivatives, 6-11 parts of multi-carbon alcohol, 5-10 parts of a surfactant, 0.5-1 part of a defoaming agent, 5-10 parts of a phosphate, 20-30 parts of water-soluble macromolecules and 30-40 parts of water. The invention has the beneficial effects that the vegetable fat raw material is used as a basic raw material, is fully degradable, environment-friendly and pollution-free, and has a good anti-caking effect; hydrophilic water-soluble polymer substances are spread on the surface of a fertilizer, so that the activity of water molecules is reduced, the "dissolution-crystallization process" among fertilizer particles is hindered, and the anti-caking purpose of the fertilizer is achieved; the surfactant is used for improving the spreadability of the water-based fertilizer polymer substances on the surface of the chemical fertilizer; low-carbon alcohol and water are mainly used as carriers of the anti-caking agent; and the temperature-resistant black coats the fertilizer by the fertilizer anti-caking agent, so that the fertilizer is black and has strong temperature resistance and covering performance.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a fertilizer anti-caking coating agent and a preparation method thereof. Background technique [0002] There are three main forms of nitrogen fertilizers currently used in my country: ammonium nitrogen, nitrate nitrogen, and amide nitrogen. Nitro fertilizer is a high-concentration compound fertilizer containing ammonium nitrogen and nitrate nitrogen. Compared with urea, the nitrate nitrogen in nitro fertilizer can be directly absorbed by the roots of crops without secondary conversion, with fast absorption and less loss. High utilization rate. [0003] Nitro compound fertilizer is an important agricultural fertilizer. It is mainly suitable for economic crops such as tobacco, corn, melons and fruits, vegetables, and fruit trees, as well as alkaline soil and karst landform areas. The application effect in alkaline soil and karst landform areas is better than urea. ...

Problems solved by technology

[0006] The traditional anti-caking agent has complicated manufacturing process and high cost, and the obtained anti-caking agent has poor performance, and long-term use will cause certain pollution to the soil

[0007] Traditional oil-soluble anti-caking agents and inert powder anti-caking agents only have a certain anti-caking effect on granular chemical fertilizers, while powdered or crystalline fertilizers have serious caking due to their small particle size and large specific surface area. The above method of wrapping oil powder and other methods can no longer achieve the ideal anti-caking effect, and the above-mentioned traditional oil and powder-coated fertilizers will produce slick oil and dust during production and use, which are not easy to degrade under natural conditions, thus causing environmental pollution.
