preparation example Construction

[0031] A kind of preparation method of the mixture of modified calcium chloride and attapulgite powder provided by the embodiment of the present invention comprises the following steps:

[0032] S1, you can take 15-23 parts of calcium chloride powder (by mass, the same below), 70-90 parts of attapulgite powder, 0.2-0.7 parts of octadecylamine and 0.2-0.7 parts of ammonium dodecylsulfonate are mixed and added Pour into a container to form a powdery mixture. When preparing in small quantities, the container can be a beaker; when producing in large quantities, the container can be a large stainless steel reaction vessel.

[0033] S2. The powdery mixture can be acid-treated, and then the powdery mixture can be neutralized.

[0034] S3. The powdery mixture can be dried to obtain a modified calcium chloride and attapulgite powder mixture with a nanoporous (microporous) structure. The prepared mixture can be sealed for future use.

[0035] Understandably, calcium chloride can be u...

Embodiment 1

[0060] Experimental parameters:

[0061] Case 1:

[0062] ①Choose 65 parts of modified calcium chloride and attapulgite powder, 15 parts of calcium propionate, 15 parts of chitosan, and 5 parts of dimethylpyrazole phosphate to prepare powdery nano synergist; Add 0.2 parts of the prepared powdery nano synergist (N, P and K content ratio is 18:8:18, the following cases are the same) to the fertilizer to make a new nitro compound fertilizer finished product.

Abstract

The invention is applicable to the technical field of compound fertilizer preparation, and discloses preparation methods of a mixture, a powder nano synergist, and a nitro-compounded fertilizer. The preparation method of the mixture of the modified calcium chloride and the attapulgite powder comprises the following steps: S1, preparing 15-23 parts of calcium chloride powder, 70-90 parts of attapulgite powder, 0.2-0.7 part of octadecylamine and 0.2-0.7 part of ammonium dodecyl sulfate, mixing the components and adding the mixture into a container to form a powdery mixture; S2, carrying out acidtreatment on the powdery mixture, and then carrying out neutralization treatment on the powdery mixture; and S3, drying the powdery mixture to obtain a modified calcium chloride and attapulgite powder mixture with a nano-porous structure. According to the preparation methods of the mixture, powder nano synergist, and nitro-compounded fertilizer, the problems that the nano synergist prepared at the present stage is single in structure and single in function are solved, the liquid and the powder are moderate, the preparation process is simple, the cost is low, and the nano synergistic effect can meet the requirement for diversity of the compound fertilizer at the present stage.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer preparation, and in particular relates to a mixture, a powdery nano synergist and a preparation method of nitro compound fertilizer. Background technique [0002] At present, the nano-synergist has a single structure and a single function, more liquid and less powder, the preparation process is more complicated, and the cost is higher. The nano-synergist effect cannot fully meet the current situation of the diverse needs of compound fertilizers. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems, and provides a preparation method of a mixture, a powdery nano-synergist and a nitro compound fertilizer, which solves the problem of single structure and single function of preparing a nano-synergist at the present stage. The problem is that the liquid and powder are moderate, the preparation process is simple, the c...
