Embodiment 1
[0032] Preparation of additives:
[0033] Described auxiliary agent consists of the following components in parts by weight:
[0034] Ethylene oxide: 25, KOH: 0.3, acetic acid: 0.4,
[0035] Dodecylamine: 16, octadecylamine: 15, tallowamine: 5,
[0036] Polypropylene: 16, fatty acid methyl ester: 25.
[0037] The preparation method of the auxiliary agent is as follows: put dodecylamine, octadecylamine, tallow amine, fatty acid methyl ester and KOH into a 1L reaction kettle equipped with a thermometer, a stirrer and a jacket. Dehydration under vacuum for 1.5 hours; then replaced with N2 for 3 times, and after the water content is qualified, feed polypropylene into the reaction kettle at 115°C; when the temperature in the kettle rises and the pressure drops, continuously feed ethylene oxide; After passing through, heat preservation and aging at 120°C for 1.5 hours to normal pressure, vacuumize, discharge, and add acetic acid to neutralize to get the finished product.
Embodiment 2
[0039] A kind of glyphosate ammonium salt soluble granule additive, in parts by weight, consists of the following components:
[0040] Ammonium glyphosate: 793, ammonium sulfate: 97, additives: 100, water: 8.
[0041] According to the ratio, add ammonium glyphosate and ammonium sulfate into the mixer and mix; the mixed material is pulverized by a pulverizer, and slowly add additives and evenly into the mixed material, then add water, continue Knead into a wet material without obvious lumps; move the above kneaded material to a granulator for granulation. Dry the obtained soluble granules at no higher than 50°C (for 2 hours), and sieve through a sieve with an appropriate diameter to obtain the finished glyphosate soluble granules.
