Problems solved by technology

[0005] In the prior art, waste oil or waste oil is used to prepare chemical fertilizer anti-coagulation agents. Most of them directly deposit the waste oil or waste oil to simply remove the impurities in the waste oil, or go through simple decolorization, deodorization, dewatering and other conventional methods. Process treatment without modifying the used oil, the unmodified oil has a low solid fat content, and there are certain deficiencies in antioxidant capacity, thermal stability, plasticity, etc., and it is easy to cause Poor use effect and unstable product quality

Embodiment 1

[0032] Embodiment 1 adopts the following steps to realize the present invention:

[0033] 1. Preparation of hydrogenated waste oil: take attapulgite as the carrier, add nickel and aluminum oxide, the ratio of nickel to aluminum is 6:1, mix evenly, put it in a high-temperature furnace and roast to 350 ° C, after roasting for 3 hours, cool to room temperature to obtain Catalyst: inject waste oil into the reaction kettle, vacuumize, add the prepared catalyst, carry out hydrogenation reaction at a reaction temperature of 190°C and a hydrogen pressure of 1.0Mpa, react for 6 hours, filter while it is hot, take the filtrate to cool and solidify into an oily paste, That is, hydrogenated waste oil is obtained; the filter residue is used as a catalyst for recycling;

[0034] 2. Preparation of pasty hydrogenated waste oil fertilizer anti-caking agent:

[0035] (1) Formula: 85% hydrogenated waste oil, 3% octadecylamine, 9% oleic acid amide, C 14 Alkyl carboxylic acid 2%, OP-10 emulsifie...

Embodiment 2

[0038] Embodiment 2 adopts the following steps to realize the present invention:

[0039] 1. Preparation of hydrogenated waste oil: take attapulgite as the carrier, add nickel and aluminum oxide, the ratio of nickel to aluminum is 6:1, mix evenly, put it in a high-temperature furnace and roast to 350 ° C, after roasting for 3 hours, cool to room temperature to obtain Catalyst: inject waste oil into the reaction kettle, vacuumize, add the prepared catalyst, carry out hydrogenation reaction at a reaction temperature of 180°C and a hydrogen pressure of 1.5Mpa, react for 7 hours, filter while it is hot, take the filtrate to cool and solidify into an oily paste, That is, hydrogenated waste oil is obtained; the filter residue is used as a catalyst for recycling;

[0040] 2. Preparation of pasty hydrogenated waste oil fertilizer anti-caking agent:

[0041] (1) Formula: 90% hydrogenated waste oil, 1.5% stearylamine, 5% oleic acid amide, C 15 Alkyl carboxylic acid 2%, OP-10 emulsifi...

Embodiment 3

[0044] Example 3 Using the hydrogenated waste oil obtained in Example 1 as one of the raw materials, a pasty hydrogenated waste oil fertilizer anti-caking agent was prepared as follows:

[0045] (1) Formula: 80% hydrogenated waste oil, 5% stearylamine, 10% oleic acid amide, C 20 Alkyl carboxylic acid 3%, OP-10 emulsifier 2%;

[0046] (2) Preparation method: heat and stir the solid raw materials in the raw materials until they melt to obtain a mixed liquid, then bring the temperature of the above mixed liquid to 70°C, slowly add the remaining liquid raw materials in the raw materials, and stir for 40 minutes to react, while stirring Cool down, stop stirring after the solution starts to thicken, and cool at room temperature to obtain the solution.

Abstract

The invention discloses a chemical fertilizer anti-caking agent prepared from hydrogenated drainage oil and belongs to the technical field of production of chemical fertilizer auxiliaries. The chemical fertilizer anti-caking agent is a pasty or powdered chemical fertilizer anti-caking agent which is prepared from hydrogenated drainage oil prepared by means of hydrogenation. The chemical fertilizer anti-caking agent disclosed by the invention is good in anti-caking performance, small in use amount and low in cost and simultaneously suitable for chlorine-based, nitro-based, urea-based and sulfenyl chemical fertilizers and the like. The oxidation resistance and thermal stability of the hydrogenated drainage oil are changed and the using effect of the chemical fertilizer anti-caking agent is improved, so that the quality of the product is stable; in addition, the raw material drainage oil is abundant and low in price and the product has high additional value and relatively high market competitiveness.

Description

technical field [0001] The invention relates to a chemical fertilizer additive, in particular to a hydrogenated waste oil fertilizer anti-caking agent, which belongs to the technical field of fertilizer additive production. Background technique [0002] The problem of chemical fertilizer caking is a problem that the chemical fertilizer industry has been committed to solving for a long time, especially ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium phosphate, urea and compound fertilizers are prone to caking. The agglomeration of chemical fertilizers seriously affects the fertilizer efficiency and brings many difficulties to storage, transportation and use. At present, the solution-type organic anti-caking agent with low viscosity is particularly promising. It is used as an external treatment of surface coating. Most of them use octadecyl primary amine as the main raw material and oil as the solvent. Mineral oil, palm oil, soybean oil, etc. However, with...
