Problems solved by technology

Because this moisture absorption or caking is caused by the hydrophilicity of the fertilizer itself, it is difficult to completely prevent this phenomenon
[0003] In the past, in order to eliminate caking, the first prerequisite was to prevent moisture absorption. The method used was to mix chemical fertilizers with low hygroscopicity into fertilizers with high hygroscopicity to make mixed fertilizers or chemical fertilizers, or to mix powdered fertilizer granules chemical, or stick non-hygroscopic powdery stabilizers (such as diatomaceous earth, kaolin, talc, etc.) It is impossible to completely prevent moisture absorption and caking

Embodiment 1

[0022] Preparation of Modified Xanthan Gum Polysaccharide

[0023] (1) Esterification of xanthan gum polysaccharides: dissolving xanthan gum in a sodium hydroxide solution with a pH of 8-10 (the molar ratio of xanthan gum to sodium hydroxide solution is 1:25-50), at a temperature of 20 Carry out swelling at -50°C for 1-3h, then add acetic acid (the molar ratio of xanthan gum to acetic acid is 1:1.2-2), and wait for the reaction to complete;

[0024] (2) separating the xanthan gum polysaccharide after the esterification: cooling the reaction system after the reaction in step (1) at room temperature, then separating crystals, suction filtration, and finally drying to obtain the xanthan gum polysaccharide after the esterification;

[0025] (3) preparation of modified xanthan gum polysaccharide: xanthan gum polysaccharide after the esterification of step (2) and ammonium cerium nitrate are made modified xanthan gum polysaccharide (xanthan gum polysaccharide after esterification) u...

Embodiment 2

[0027] Preparation of anti-caking agent

[0028] 10 parts of sodium lauryl sulfate, 10 parts of paraffin, 23 parts of modified xanthan polysaccharide and 20 parts of polyglutamic acid.

[0029] Weigh the surfactant, paraffin wax, modified xanthan gum polysaccharide and polyglutamic acid in parts by weight, heat to 50° C. to 75° C., and mix uniformly to obtain the anti-caking agent.

Embodiment 3

Abstract

The invention discloses a synergistic biological polysaccharide anti-hardening agent, and relates to the technical field of anti-hardening agents. The synergistic biological polysaccharide anti-hardening agent disclosed by the invention is prepared from the following components in parts by weight: 10 to 40 parts of a surfactant, 10 to 20 parts of paraffin, 23 to 27 parts of modified xanthan gum polysaccharide and 20 to 30 parts of polyglutamic acid. According to the invention, the modified xanthan gum polysaccharide prepared by performing molecular modification on xanthan gum can prevent moisture transfer and recrystallization among inorganic salt particles in a compound fertilizer, and the anti-hardening agent prepared by combining the modified xanthan gum polysaccharide with a surfactant, paraffin and polyglutamic acid has the advantage of good anti-hardening effect; and the preparation method of the anti-hardening agent is simple.

Description

technical field [0001] The invention relates to an anti-caking agent, in particular to a synergistic biological polysaccharide anti-caking agent and a preparation method thereof. Background technique [0002] With the development of modern agricultural technology, the area of ​​economic crops is too large, and the demand for quick-acting chemical fertilizers is increasing. At present, compound fertilizers made of potassium sulfate, ammonium phosphate, and ammonium nitrate have high hydrophilicity and are used in storage. Agglomeration may occur during transportation. Since this moisture absorption or caking is caused by the hydrophilicity of the fertilizer itself, it is difficult to completely prevent this phenomenon. [0003] In the past, in order to eliminate agglomeration, the first prerequisite was to prevent moisture absorption. The method used was to mix chemical fertilizers with low hygroscopicity into fertilizers with high hygroscopicity to make mixed fertilizers or...
