[0047] The preparation method of above-mentioned anti-hardening oil comprises the following steps:

[0048] Step S110, mixing and dissolving the polymer with water to obtain an aqueous solution of the polymer.

[0049] In one of the embodiments, the high molecular polymer is added into water at 90° C. and fully stirred to dissolve.

[0050] Step S120, heating palm oil to 60°C-70°C, adding paraffin, oleic acid, surfactant and sorbitan fatty acid ester and stirring evenly to obtain a mixture; and

[0051] In one of the examples, the palm oil is heated to 70°C.

[0052] In one embodiment, the stirring speed is 100r / min-300r / min, preferably 300r / min.

[0053] In one embodiment, the palm oil is heated to 60° C. to 70° C., paraffin wax and oleic acid are added, stirring is started, a surfactant is added and sorbitan fatty acid ester is mixed to obtain an emulsifier to obtain a mixture.

[0054] Step S130, mixing and stirring the aqueous solution of the high molecular polymer and ...

Embodiment 1

[0072] The preparation of the anti-compaction fertilizer of embodiment 1 comprises:

[0073] PEG-2000 is mixed with water and fully dissolved to obtain an aqueous solution of high molecular polymer.

[0074] Heat 85 parts of palm oil to 70°C, add 5 parts of paraffin, 4 parts of oleic acid, 1 part of sodium lauryl sulfate (surfactant), 2 parts of Span-60, start stirring at 300r / min, add 4 parts of high molecular polymer aqueous solution, stirred for 2 hours to obtain anti-hardening oil.

[0075] The nitro compound fertilizer and the anti-hardening oil are evenly mixed according to the mass ratio of 1000:1.8, so that the anti-hardening oil is attached to the surface of the fertilizer particles to obtain the anti-hardening fertilizer 1-1.

[0076] The urea-based compound fertilizer and the anti-hardening oil are evenly mixed according to the mass ratio of 1000:1.8, so that the anti-hardening oil is attached to the surface of the fertilizer particles to obtain the anti-hardening ...

Abstract

The present invention involves a kind of anti -board oil and oil, its preparation methods and anti -board fertilizers.A kind of anti -board oil, according to the number of quality portions, including: 80 to 90 copies of palm oil; 2 to 5 parts of paraffin; 1 to 2 parts of the surfactant; 2 parts of sorge glycol fatty acid ester, 2 parts to 5 copies to 5 parts; 2 to 5 copies of oleic acid; 1 to 2 parts of polymer polymers; and 2 to 5 parts; of which, at least one of the polymer polymers is selected from polyethylene glycol and polyethylene glycols and polyethylene glycols and polyethylene glycols.EssenceThe above -mentioned anti -board oil does not need to be coordinated with the anti -plate powder, no heating and can prevent powder when used.

Description

technical field [0001] The invention relates to an anti-hardening oil, a preparation method thereof and an anti-hardening fertilizer. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization, and is the best way to organically combine irrigation and fertilization. According to the calculation of China's 900 million mu of irrigated area, the current proportion of integrated application of water and fertilizer is only 2.87%, so the development prospect is broad. In Israel, the United States and other agricultural developed countries, the use of water and fertilizer integration technology is very common, and liquid fertilizers or fast-dissolving powdered multi-element fertilizers are mainly used. However, liquid fertilizers require supporting pipelines extending in all directions and need to be transported over long distances. In contrast, powdered multi-element fertilizers that can ...
