Embodiment 1

[0022] The water-based fertilizer anticaking agent comprises polyacrylamide: 10-50%, fatty alcohol polyoxyethylene ether: 5-20%, methanol: 10-20% and water: 10-75%. Its preparation method comprises the following steps:

[0023] S1. Add 10-75% water by mass percentage to the reaction vessel with a stirring device and a heating device, and heat it;

[0024] S2. When the heating temperature reaches 35-40°C, add 5-20% fatty alcohol polyoxyethylene ether and 10-20% methanol by mass percentage, and continue stirring and heating during the addition process;

[0025] S3. When the heating temperature is stabilized at about 60°C, add 10-50% polyacrylamide by mass percentage, and continue to stir until each component is dissolved and dispersed completely, thus making the water-based anti-caking fertilizer agent (referred to as Fubon water agent, the same below).

[0026] In this embodiment, the fatty alcohol polyoxyethylene ether can be linear or branched, and the number of carbon atom...

Embodiment 2

[0033] The water-based fertilizer anticaking agent comprises polyvinylpyrrolidone: 20-30%, fatty alcohol polyoxyethylene ether sodium carboxylate: 10-15%, ethanol: 12-18% and water: 40-50%. Its preparation method comprises the following steps:

[0034] S1. Add 40-50% water by mass percentage to the reaction vessel with a stirring device and a heating device, and heat it;

[0035] S2. When the heating temperature reaches 35-40°C, add 10-15% by mass percentage of fatty alcohol polyoxyethylene ether sodium carboxylate and 12-18% by mass percentage of ethanol, and keep stirring and heating;

[0036] S3. When the heating temperature is stabilized at about 60°C, add 20-30% polyvinylpyrrolidone by mass percentage, and continue to stir until each component is dissolved and dispersed completely, thus obtaining the anti-caking water-based fertilizer agent.

[0037] In this embodiment, the sodium fatty alcohol polyoxyethylene ether carboxylate can be linear or branched, and the number...

Embodiment 3

[0044] The water-based fertilizer anticaking agent includes a mixture of polyvinylpyrrolidone and polymethacrylic acid: 10%, a mixture of fatty alcohol polyoxyethylene ether sodium carboxylate and fatty alcohol polyoxyethylene ether sodium sulfonate: 5%, a mixture of methanol and ethanol: 10% and water: 75%. Its preparation method comprises the following steps:

[0045] S1, add 75% water by mass percentage in the reaction container with stirring device and heating device, and heat;

[0046] S2. When the heating temperature reaches 35°C, add 5% by mass percentage of fatty alcohol polyoxyethylene ether sodium carboxylate and fatty alcohol polyoxyethylene ether sodium sulfonate mixture and 10% by mass percentage of methanol and ethanol mixture, And continue to stir and heat during the addition process;

[0047] S3. When the heating temperature is stabilized at about 60°C, add 10% by mass percentage of polyvinylpyrrolidone and polymethacrylic acid mixture, and continue to stir u...

Abstract

The invention relates to a water-based fertilizer anticaking agent and a preparation method thereof. The water-based fertilizer anticaking agent comprises the following components in percentage by mass: 10-50% of water-soluble high polymer, 5-20% of surfactant, 10-20% of low-carbon alcohol and 10-75% of water. The invention is applicable to preparation and application of the powdery or crystalline chemical fertilizer anticaking agent. Compared with the traditional process based on oil/power coating, the water-based fertilizer anticaking agent prepared by the method has the advantages of low consumption and better anticaking effect, and well solves the problem that the powdery or crystalline chemical fertilizer can not prevent caking by oil/power coating. Meanwhile, the production and preparation technique of the anticaking agent is simple to operate and easy to implement, and is free of pollution and convenient for industrial production.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a water-based fertilizer anti-caking agent and a preparation method thereof, and is especially suitable for the preparation and application of powdery or crystalline fertilizer anti-caking agents. Background technique [0002] Chemical fertilizers, whether they are powdered or granular, will agglomerate under certain conditions and lose their fluidity, forming hard lumps. This phenomenon is called fertilizer agglomeration. Fertilizer agglomeration usually occurs during the storage, loading and unloading and transportation of fertilizers. Fertilizer agglomeration is mainly caused by factors such as water exchange between fertilizer particles, salt dissolution and recrystallization, and formation of salt bridges. It not only affects the appearance of fertilizers, but also reduces their use efficiency. Currently commonly used fertilizer anti-caking agents are oil-soluble anti-c...
