Examples
Embodiment 1
[0024] Example 1: 42% emulsifiable concentrate
[0025] The formula is composed of: 35% of active ingredient A, 7% of active ingredient B, 4% of emulsifier styrylphenol polyoxyethylene ether, 5% of emulsifier sorbitan ester salt, and 100% of solvent xylene.
[0026] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.
Embodiment 2
[0027] Embodiment 2: 35% suspending agent
[0028] The formulation consists of: 7% active ingredient A, 28% active ingredient B, 4% wetting agent alkyl succinate sulfonate, 4% dispersing agent polycarboxylate, 5% antifreeze propylene glycol, thickener Magnesium aluminum silicate 0.2%, water to make up to 100%.
[0029] The preparation method is: put the active ingredient, wetting agent, dispersant, antifreeze and water into the stirring tank, after fully stirring, pump the material into the sand mill for full grinding, after the grinding is completed, pump it into the high-speed shearing machine In the process, after adding the thickener, high-speed shearing is carried out, and the suspending agent is obtained after the shearing is completed.
Embodiment 3
[0030] Example 3: 65% water dispersible granules
[0031] The formula is composed of: 52% active ingredient A, 13% active ingredient B, 7% sodium lauryl sulfate as a wetting agent, 5% alkylphenol polyoxyethylene ether phosphate as a dispersant, and 4% ammonium sulfate as a disintegrating agent %, binder carboxymethyl cellulose 0.2%, filler diatomaceous earth to make up to 100%.
[0032] The preparation method is as follows: after all the materials are mixed uniformly, pulverized by an airflow mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain the water-dispersible granules.
