The present invention relates to pesticide herbicide and preparation method thereof, refer to particularly a kind of 2, soluble granule of 4-D dimethylamine salt and preparation method thereof.
Background technology
2,4-D, claim again 2,4-D acid, (2,4-dichlorophenoxy) acetic acid, 2,4-drips, 2,4-dichlorophenoxyacetic acid, it is the interior absorption conduction hormone herbicide that a kind of selectivity is very strong, has toxic action, thereby be widely used in the gramineous crop Tanaka preventions such as paddy rice, corn, wheat, barley, oat, herbage, Chinese sorghum, sugarcane and remove 1 year and perennial broadleaf weed, nutgrass flatsedge and some malignant weed when high concentration is used.
At present, the main formulation of 2,4-D has ester class missible oil, amine salt aqua, sodium salt soluble powder.Wherein, 2,4-D dimethylamine salt aqua is produced and is used the most extensive.Yet, high-load 2,4-D dimethylamine salt aqua, as the aqua of 840g/l, 860g/l, 900g/l specification, during lower than 15 ℃, easily separates out mass crystallization at temperature; Can integrally curing during lower than 5 ℃ at temperature, cannot take out, give and produce and sell and use and bring many puzzlements.
Although have for many years a lot of personnel to carry out research of technique, fail effectively to solve a low temperature crystallization difficult problem always.The present invention is exactly for this situation, and has one's eyes on the future, and a kind of brand-new solution is provided, and adopts 2,4-D dimethylamine salt bulk drug to prepare 2,4-D dimethylamine salt soluble granule.Through fully investigation discovery, yet there are no at present the exploitation of 2,4-D dimethylamine salt soluble granule and the report of registration both at home and abroad.
Summary of the invention
The object of this invention is to provide a kind of 2, soluble granule of 4-D dimethylamine salt and preparation method thereof, this soluble granule has and uses and convenient transportation, stores the features such as safety and stability, can effectively avoid low temperature crystallization.
Technical scheme of the present invention: a kind of 2, the soluble granule of 4-D dimethylamine salt, its component and percentage by weight thereof are as follows: 2,4-D dimethylamine salt is 10%～98%, and binding agent is 0.1%～15%, and synergist is 0.1%～5%, and surplus is filler.
The good technical scheme of the present invention: 2,4-D dimethylamine salt is 30%～98%, binding agent is 1.5%～11%, and synergist is 0.7%～5%, and surplus is filler.
In such scheme, described binding agent is one or more in Magnesiumaluminumsilicate, polyvinyl alcohol, polyethylene glycol, sodium cellulose glycolate, gelatin, gum Arabic, xanthans, Sodium Polyacrylate, polyvinylpyrrolidone, soluble starch, polycarboxylate, polyethylene glycol ethers, fructose and glucose, preferably polyethylene glycol, sodium cellulose glycolate, polyvinylpyrrolidone, soluble starch or polycarboxylate; Described synergist is one or more in silicone based, azone, thiophene ketone, Tea Saponin and penetrant t, preferably azone, Tea Saponin or penetrant t; Described filler is one or more in ammonium sulfate, sodium sulphate, sodium chloride, ammonium chloride and urea.The raw material using in such scheme is buied by market.
The present invention relates to described 2, the preparation method of the soluble granule of 4-D dimethylamine salt, it comprises the steps: percentage by weight is 10%～98% 2, the filler of the binding agent that 4-D dimethylamine salt, percentage by weight are 0.1%～15%, the synergist that percentage by weight is 0.1%～5% and surplus carries out granulation after mixing, then gained granula after granulation is dry.Wherein, described prilling process comprises rotary table granulation method, screw extruding comminution granulation, high strength mixing granulation, rotary squeezing comminution granulation.
The better technical scheme of the present invention: it comprises the steps: percentage by weight is 30% 2, the ammonium sulfate that the penetrant t that 4-D dimethylamine salt, percentage by weight are 7%, percentage by weight are 52% is fully mixed to get 2,4-D dimethylamine salt soluble powder, to limit in the rotating disc tilting, add gained 2 again, it is that 11% the soluble starch aqueous solution carries out granulation that 4-D dimethylamine salt soluble powder limit sprays into percentage by weight, gained granula drying get final product 2,4-D dimethylamine salt soluble granule.
The invention has the advantages that: this preparation method is reliable, obtain 2, the soluble granule granule strength of 4-D dimethylamine salt is high, dissolution dispersity can be excellent, it and the comparison of 2,4-D dimethylamine salt aqua, have and use and convenient transportation, store safety and stability, can in high latitude area, sell, use and produce, be not subject to seasonal effect simultaneously.
