Problems solved by technology

[0003] CN106380321B discloses an anti-caking agent for compound fertilizer and its preparation and use method. An anti-caking agent for compound fertilizer consists of vegetable oil, paraffin, stearic acid, surfactant, octadecylamine, vinyl acetate, peroxide The composition of benzoyl, the mass percentage of each component is as follows: vegetable oil: 40.0-70.0%; paraffin: 10.0-30.0%; stearic acid: 1.0-10.0%; octadecylamine: 1.0-10.0%; 10.0%; surfactant: 1.0-10.0%; benzoyl peroxide: 0.02-0.20%, the sum of the above components is 100%, although it can achieve better moisture-proof and waterproof, but dibenzoyl peroxide is A strong oxidizing agent, flammable
The nature is extremely unstable, friction, impact, exposure to bright light, high temperature, sulfur and reducing agents, etc., all have the danger of causing fire and explosion, and can also cause combustion when sulfuric acid is added, so there is a great safety hazard for production

Abstract

The invention discloses a compound fertilizer anti-caking agent and a preparation process thereof. The compound fertilizer anti-caking agent is prepared from vegetable oil, calcium stearate, polylactide, a rare earth catalyst, a surfactant, a lubricant, viscous oil and stearic acid. The preparation process of the compound fertilizer anti-caking agent mainly comprises the following steps: 1, preparing a high-temperature-resistant material; 2, fusing; and 3, melting. The calcium stearate and polylactide form a calcium stearate and polylactide mixed film with an interpenetrating network structureunder the catalytic action of the rare earth catalyst, so that the synergistic moisture-proof and water-proof effects are achieved, and the moisture-proof and water-proof capacity is improved; and the calcium stearate and the polylactide are non-toxic products, and the polylactide also has a degradation effect, so that the environmental protection property of the anti-caking agent is improved.

Description

technical field [0001] The invention relates to the field of chemical fertilizer additives, in particular to a compound fertilizer anti-caking agent and a preparation process thereof. Background technique [0002] At present, the main raw materials for compound fertilizer production are: urea, ammonium chloride, ammonium nitrate, ammonium sulfate, monoammonium phosphate, diammonium phosphate, superphosphate, heavy calcium, potassium chloride, potassium sulfate, etc. These fertilizers have large Solubility and low moisture absorption point, and the moisture absorption point of the compound fertilizer made of them is lower than that of a single fertilizer, which also causes the compound fertilizer made of these fertilizers to agglomerate more easily during storage and transportation, and the agglomeration Fertilizers need to be broken in the process of use and testing, which not only increases the labor load but also has potential unsafe factors, which brings inconvenience to ...
