Embodiment 1

[0018] Weigh 10kg of dioctyldimethylammonium chloride, 1kg of nonylphenol polyoxyethylene ether (TX-10), and 89kg of methyl oleate in a mixing tank, and stir at room temperature for 1 hour to obtain a uniform and stable 100 kg liquid anti-caking agent.

[0019] Apply this anti-caking agent to 15-15-15 (N-P 2 o 5 -K 2 O) Compound fertilizer, the addition amount is 1 kg / t, the test method is shown in ZL201310532859.2, and the measured relative caking rate is 13%.

Embodiment 2

[0021] Weigh 2 kg of dioctadecyl dimethyl ammonium chloride, 5 kg of octylphenol polyoxyethylene ether (OP-3), and 93 kg of methyl oleate in a mixing tank, and stir at room temperature for 1 hour to obtain Uniform and stable 100 kg liquid anti-caking agent.

[0022] Apply this anti-caking agent to 25-13-7 (N-P 2 o 5 -K 2 O) Compound fertilizer, the addition amount is 2 kg / t, the test method is shown in ZL201310532859.2, and the measured relative caking rate is 12%.

Embodiment 3

[0024] Weigh 2 kg of dihexadecyl diethylammonium bromide, 3 kg of nonylphenol polyoxyethylene ether (OP-7), and 95 kg of methyl oleate, respectively, and place them in a mixing tank, and stir at room temperature for 1 hour to obtain Uniform and stable 100 kg liquid anti-caking agent.

[0025] The anti-caking agent was applied to 15-15-15 (N-P2O5-K2O) compound fertilizer, the addition amount was 1 kg / t, the test method was shown in ZL201310532859.2, and the relative caking rate was measured to be 15%.

Abstract

The invention discloses a liquid anti-caking agent for compound fertilizer and belongs to the field of chemical fertilizer additives. The liquid anti-caking agent is mainly prepared from dialkyl quaternary ammonium salt, alkylphenol polyoxyethylene ether and methyl oleate, wherein a general chemical formula of the dialkyl quaternary ammonium salt is [RR'NR1R2]<+>X<->; alkylphenol polyoxyethylene ether is octylphenol polyoxyethylene ether or nonylphenol polyoxyethylene ether, and the number of EO (ethylene oxide) is 3-10. A test proves that heating is not required or any solvent is not required to be added in a use process of the anti-caking agent, the anti-caking agent can be directly sprayed on the surfaces of chemical fertilizer particles, and a relative caking rate is 15% or lower. A heating and heat-insulating device can be omitted during production, energy consumption can be reduced remarkably, and benefits are increased.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer additives. Background technique [0002] Compound fertilizer occupies a very important position in the fertilizer industry because it integrates multiple nutrients. However, due to temperature fluctuations in the process of transportation and storage, compound fertilizers exchange water with the environment, dissolve and crystallize salt, and produce salt bridges. Glue fertilizer granules together. In addition, fertilizer granules are squeezed during stacking, which leads to plastic deformation and promotes the agglomeration of fertilizers. The caking problem not only brings troubles to the storage and transportation of chemical fertilizer production enterprises, but also causes great inconvenience to users. The fertilizer loses fluidity and forms hard lumps. This kind of caking is the most unfavorable to mechanical fertilization. . In order to avoid the caking of compound fertilizers, the mo...
