Embodiment 1
[0044] A kind of preparation method of pyraclostrobin and copper rosinate suspending agent, its steps are as follows:
[0045] (1) preparation of potassium hydroxide solution: get 40Kg potassium hydroxide and be dissolved in 400Kg water, obtain potassium hydroxide solution;
[0046] (2) Preparation of saponification solution: add 210Kg rosin to the potassium hydroxide solution obtained in step (1), and heat to 90° C., react for 60 minutes, until the reaction is complete, to obtain saponification solution;
[0047] (3) Melting of pyraclostrobin: Add 20.5Kg of pyraclostrobin technical substance (crystal form II, content 97.5%, melting point 63.7-64.1°C) to the saponified solution obtained in step (2), and keep the temperature At 90°C, the pyraclostrobin raw drug was melted, then 3Kg of commercially available polyvinyl alcohol was added as a stabilizer, and stirred for 30 minutes to obtain a stable pyraclostrobin soap mixture;
[0048] (4) Preparation of copper sulfate solution: 1...
Embodiment 1
[0053] According to the proportion of the formula, a sufficient amount of pyraclostrobin technical substance (crystal form II, content 97.5%, melting point 63.7-64.1°C) and copper rosinate technical substance (content 65%), wetting agent, dispersant, Thickener, antifreeze, etc. are mixed with water, subjected to high-speed shearing, wet sanding, and finally homogeneously filtered to obtain the product. The main equipment is batching kettle, colloid mill or homogeneous mixer, sand mill.
[0054] Formula: Accurately weigh 20.5Kg of commercially available pyraclostrobin (crystal form II, content 97.5%, melting point 63.7-64.1°C), 307.7Kg of commercially available copper rosinate (content 65%); dispersant is 40Kg commercially available Castor oil polyoxyethylene ether is sold; the wetting agent is 10Kg commercially available alkylnaphthalene sulfonate polycondensate; the thickener is 1Kg commercially available xanthan gum; the antifreeze is 30Kg commercially available ethylene gly...
Embodiment 2
[0064] A kind of preparation method of pyraclostrobin and copper rosinate suspending agent, its steps are as follows:
[0065] (1) preparation of potassium hydroxide solution: get 20Kg sodium hydroxide and be dissolved in 400Kg water, obtain sodium hydroxide solution;
[0066] (2) Preparation of saponification solution: add 105Kg rosin to the potassium hydroxide solution obtained in step (1), and heat to 90° C., react for 60 minutes, until the reaction is complete, to obtain saponification solution;
[0067] (3) Melting of pyraclostrobin: Add 208.4Kg pyraclostrobin technical material (crystal form I, content 96%, melting point 64.6-65.2°C) to the saponified solution obtained in step (2), and keep the temperature At 90°C, the pyraclostrobin raw drug was melted, then 1Kg of commercially available polyvinyl alcohol and 2Kg of commercially available polyacrylic acid resin were added as stabilizers, and stirred for 30 minutes to obtain a stable pyraclostrobin soap mixture;
