preparation example 1

[0043] Preparation Example 1: 30% Amphetamine · Chlorphenamide Suspension Concentrate (1:3) (7.5%+22.5%)

[0044] In terms of weight percentage, 7.5% of pyrafenone, 22.5% of chlorophenyl ether amide, 1% of fatty alcohol polyoxyethylene ether, 3% of styrylphenol polyoxyethylene ether phosphate salt, and 1% of polycarboxylate sodium salt , alkyl aryl polyoxyethylene polyoxypropylene ether 2%, magnesium aluminum silicate 1%, xanthan gum 0.2%, sodium sorbate 0.5%, silicone oil 0.5%, ethylene glycol 5%, deionized water to make up the balance .

[0045] Preparation method: Mix water, dispersant, and wetting agent evenly, then add defoamer and antifreeze successively under stirring state, and mix evenly by high-speed shearing, then add fenpyrafen and chlorphenamide, and continue shearing Cut and mix evenly, then grind in a horizontal sand mill, control 90% of the particle size of the material below 5 μm, finally add a thickener, and shear evenly to obtain the suspending agent of the...

preparation example 2

[0046] Preparation Example 2: 20% Amphetamine · Chlorphenamide Suspension Concentrate (3:1) (15%+5%)

[0047]In terms of weight percentage, fenflufen 15%, chlorophenyl ether amide 5%, isomerized tridecanol polyoxyethylene ether 1%, polycarboxylate sodium salt 1%, alkylaryl polyoxyethylene polyoxypropylene Ether 2%, alkylphenol polyoxyethylene ether phosphate 3%, silicone oil 0.4%, magnesium aluminum silicate 1%, isothiazolinone 0.1%, xanthan gum 0.3%, propylene glycol 5%, deionized water to make up the rest quantity.

[0048] Preparation method: same as preparation example 1.

preparation example 3

[0049] Preparation Example 3: 3% Amphetamine Chlorphenamide Microemulsion (1:1) (1.5%+1.5%)

[0050] In terms of weight percentage, 1.5% of fenflufen, 1.5% of chlorophenyl ether amide, 15% of xylene, 20% of cyclohexanone, 15% of styryl benzene polyoxyethylene ether, EO-PO block copolymer 3%, fatty alcohol polyoxyethylene ether sodium sulfate 1%, glycerol 4%, silicone defoamer 0.05%, and deionized water to make up the balance.

[0051] Preparation method: mix the active ingredient fenpyrafen with chlorophenyl ether amide, solvent, emulsifier, etc. to obtain an oil phase, mix the antifreeze with water evenly to obtain a water phase, add water to the oil phase under stirring Stir the phases evenly, continue to cut for 10 minutes, and then add the silicone oil defoamer and stir evenly to obtain small droplets of oil phase particles with a particle size of 0.01-0.1 microns, that is, the microemulsion of the present invention is obtained.
