Description
Technical field
The present invention relates to a kind of pesticide herbicide and preparation method thereof, specifically relate to a kind of 2, water-soluble granule of 4-D choline (being water-soluble granular formulation) and preparation method thereof.
Background technology
2, the 4-D choline belongs to inhales the conduction hormone herbicide in selectivity, mainly be used in cereal crop, coniferous tree, uncultivated area, herbage, lawn, prevent and kill off annual and perennial broad leaved weed, as amaranth, lamb's-quarters, Siberian cocklebur, field bindweed, kitchen garden, common vetch, Persian Veronica, broadcast ma wormwood artemisia etc.Most of broad leaf crops, particularly cotton, very sensitive to this class weed killer herbicide, also can make processing soil treatment agent, preemergence application after soybean is broadcast.2,4-D choline has the effect identical with 2,4-D and environment-friendly advantage, but also have more other advantages, and such as low volatility, the diffusion drift is less, and peculiar smell is lighter, easy operating and being mixed, and application is more extensive opportunity.
Present 2, the main formulation of 4-D choline is its aqua, although aqua belongs to environmentally friendly formulation, and, packing and cost of transportation are higher.Nowadays the market demand becomes increasingly abundant, and today that product competition is day by day violent, develops its better formulation and is determined to win.It is reported that the report of at present relevant 2,4-D choline water-soluble granule yet there are no all documents.
Summary of the invention
The purpose of this invention is to provide a kind of 2,4-D choline water-soluble granule, this water-soluble granule composition is simple, medicament contg is high, and is environmentally friendly, compares packing and cost of transportation with existing formulation lower, the transportation and using of being more convenient for.
Another object of the present invention is to provide the preparation method of this water-soluble granule, can easily 2,4-D choline be made water-soluble granule by this preparation technology, and granulating is simple, and auxiliary material adds few, convenient operation.
The present invention is achieved through the following technical solutions:
A kind of 2,4-D choline water-soluble granule, comprise the composition of following percetage by weight: 2,4-D choline 5-99.5%, water soluble filler is mended to 100%.
Preferably, the consumption of 2,4-D choline is 20-99.5wt%, and water soluble filler is mended to 100%.
Further preferred, the consumption of 2,4-D choline is 70-99.5wt%, and water soluble filler is mended to 100%.
Preferred, the consumption of 2,4-D choline is 85-99.5wt%, and water soluble filler is mended to 100%.
Most preferred, the consumption of 2,4-D choline is 99.5%, and water soluble filler is mended to 100%.
Above-mentioned 2, in 4-D choline water-soluble granule, do not need to add any surfactant and binding agent, only need water soluble filler can make water-soluble granular, water soluble filler used is water-soluble inorganic salt, and described water-soluble inorganic salt is selected from sulphate, nitrate, hydrochloride, carbonate, bicarbonate, phosphate, phosphoric acid hydrogen disalt, dihydric phosphate, borate and silicate one or more.
Above-mentioned 2, in 4-D choline water-soluble granule, water-soluble inorganic salt used can mix according to arbitrary proportion.
Generally, 2,4-D salt need to add binding agent or just can make water-soluble granule with the surfactant of cementation, otherwise granulating is difficult, but the product medicament contg that adds after binding agent or surfactant will reduce, and can not prepare the water-soluble granule of high medicament contg.Find during research, 2,4-D choline has certain viscosity under higher temperature, in the situation that there is water to exist viscosity stronger, can satisfy the granulation requirement.According to this discovery, the present invention improves technique, makes material self have cohesive, and granulation is convenient and easy, and granulating is good, does not use adhesive and surfactant, thereby can obtain the aqueous solvent granula of high medicament contg.
Preparation method of the present invention is: with 2,4-D choline and water soluble filler, in kneader after full and uniform mixing, add 2, the water of the 0-30wt% of 4-D choline and water soluble filler total amount is mediated, mediate complete after 40-110 ℃ of granulation, under 20-90 ℃ of condition the oven dry and get final product.
In above-mentioned preparation method, do not need during granulation with adding any binding agent and surfactant, only need guarantee that compound adds water and mediates, then carry out granulation at 40-110 ℃ and get final product.
Compared with prior art, of the present invention 2,4-D choline water-soluble granule has following advantage:
1, simple and easy, the economy of the method technique, safety, whole production process is not used the dangerization product, need not organic solvent, and the feature of environmental protection is good, is easy to control and operation, and safety coefficient is high.
2, the present invention makes water-soluble granule with 2,4-D choline, has overcome the deficiency that aqua exists, and is more convenient on using.There is no the adjunct ingredients such as surfactant, adhesive in water-soluble granule of the present invention, composition is simpler, make water-soluble granule only add a small amount of water soluble filler by the improvement to technique and get final product granulating and forming, namely improved the content of medicine, avoid again the use of adhesive and surfactant, reduced cost.
3, a process for preparing 2,4-D choline water-soluble granule content is high, active constituent content can reach 99.5%, only reach 86% and active ingredient is the highest in aqua, active constituent content is higher, during product forms except the auxiliary agent of necessity, almost do not affect the impurity of product quality and follow-up use, if transport the goods of active ingredient identical weight in transportation, aqua has more 16% weight than water-soluble granule, and same freight charges also will exceed 16%.
4, a process for preparing 2,4-D choline water-soluble granule not only physico-chemical property is stable, pellet hardness is also larger, can bear certain pressure and indeformable, for storage and transportation, obvious advantage is arranged.
5, a process for preparing 2, without dust, environmental pollution is less in processing, production and use procedure for 4-D choline water-soluble granule, and is also less to the producer and user's harm.Just do not have because the harm to other crops of drifting about and causing without dust during simultaneously because of use yet.
6, a process for preparing 2,4-D choline water-soluble granule good fluidity, bulk density is large, sticking wall has reduced environmental pollution, good fluidity is easy to packing and metering.
7, a process for preparing 2,4-D choline water-soluble granule requires simple to packing material, aqua generally all needs the harder and corrosion resistant PE bucket of quality as packaging material, these packing material prices are higher, and the storage after being finished and process great difficulty is all arranged.And 2,4-D choline water-soluble granule only needs more common aluminium foil bag or two-in-one plastic woven bag packing, and then sealing just can, the packaging bag price is relatively cheap, packaging bag simultaneously is easy to process, and only needs centralized collection to there being the qualification processed in units to get final product, so relatively low at the packing material cost.
