Problems solved by technology

[0002] Compound fertilizer plays an increasingly important role in the fertilizer industry because it integrates multiple nutrients. However, compound fertilizer is more likely to agglomerate than single fertilizer during transportation and storage, which will cause its free flow to gradually disappear and make its quality For a long time, it has seriously affected the sales of manufacturers and the use of users

Embodiment 1

[0024] A preparation method of an environmental protection synergistic compound fertilizer anti-caking agent, it comprises the steps:

[0025] Step One, Ingredients

[0026] Take respectively the polyaspartic acid of 8.6% in mass parts, the polyacrylamide of 5.4%, the sodium lauryl sulfate of 12.5%, the Span-80 of 8.5%, the deionized water of 65%; The sum of the masses is 100%;

[0027] In the second step, add deionized water to the reaction kettle, heat to 50°C, add polyaspartic acid, polyacrylamide and sodium lauryl sulfate in turn under stirring, stir until dissolved, then add Span-80, Then heat-preserve and stir for 40 minutes to obtain an anti-caking agent for environment-friendly synergistic compound fertilizer.

Embodiment 2

[0029] A preparation method of an environmental protection synergistic compound fertilizer anti-caking agent, it comprises the steps:

[0030] Step One, Ingredients

[0031] Take respectively 5% polyaspartic acid, 5% polyacrylamide, 10% sodium dodecylbenzenesulfonate, 5% Tween-60, and 75% deionized water in parts by mass; The sum of the mass of the components is 100%;

[0032] In the second step, add deionized water to the reaction kettle, heat to 55°C, add polyaspartic acid, polyacrylamide and sodium dodecylbenzenesulfonate in turn under stirring, stir until dissolved, then add Tween- 60, then insulated and stirred for 40 minutes to obtain an anti-caking agent for environmentally friendly and synergistic compound fertilizers.

Embodiment 3

[0034] A preparation method of an environmental protection synergistic compound fertilizer anti-caking agent, it comprises the steps:

[0035] Step One, Ingredients

[0036] Take respectively the polyaspartic acid of 15% in mass parts, the polyacrylamide of 10%, the sodium butyl naphthalene sulfonate of 20%, the Tween-85 of 10%, the deionized water of 45%; The sum of the masses is 100%;

[0037] In the second step, add deionized water to the reaction kettle, heat to 60°C, add polyaspartic acid, polyacrylamide and sodium butyl naphthalene sulfonate in turn under stirring, stir until dissolved, then add Tween-85, Then heat-preserve and stir for 60 minutes to obtain an anti-caking agent for environment-friendly synergistic compound fertilizer.

Abstract

The invention discloses an environment-friendly synergistic anti-caking agent for a compound fertilizer. The anti-caking agent is prepared from the following components in percentage by mass: 5-15% of polyaspartic acid, 5-10% of polyacrylamide, 10-20% of an anionic surfactant, 5-10% of a non-ionic surfactant and the balance of deionized water, wherein the sum of contents of the above components is100%. The invention also discloses a preparation method of the anti-caking agent. The preparation method comprises the steps of blending raw materials, mixing, heating and stirring. Since the environment-friendly synergistic anti-caking agent for the compound fertilizer is prepared from biodegradable materials, the anti-caking agent can be completely degraded in a natural environment, and degraded products can also be used as a fertilizer for crops; polyaspartic acid has a chelating effect on metal ions, polyaspartic acid having a certain molecular weight can enrich nitrogen, phosphorus, potassium and trace elements and supply the elements to plants so that the fertilizer is efficiently utilized by plants and the yield and quality of plants are increased.

Description

technical field [0001] The invention belongs to the technical field of preparation of fertilizer anti-caking agents, in particular to an environment-friendly synergistic compound fertilizer anti-caking agent, and also relates to a preparation method of the above-mentioned anti-caking agent. Background technique [0002] Compound fertilizer plays an increasingly important role in the fertilizer industry because it integrates multiple nutrients. However, compound fertilizer is more likely to agglomerate than single fertilizer during transportation and storage, which will cause its free flow to gradually disappear and make its quality For a long time, it has seriously affected the sales of manufacturers and the use of users. In order to prevent caking, the measures that can be taken are: adopt new granulation equipment and drying process; apply various anti-caking agents to reduce the moisture content of the product and improve the strength, uniformity, anti-caking and loosenes...
