Abstract
The invention discloses a glyphosate water-soluble tablet and a preparation method thereof and belongs to the technical field of pesticides. The glyphosate water-soluble tablet is characterized by comprising, by weight, 10% to 80% of glyphosate acids and/or glyphosate salts, 5% to 40% of disintegrating agents, 5% to 20% of surface active agents, 0% to 60% of fillers and 0% to 5% of adhesion agents. Compared with various novel glyphosate granules in a current market, the glyphosate water-soluble tablet has the advantages that the processing is simple, the moisture content is extremely low, the energy consumption of a drying process is reduced, the equipment investment is small, drifted dusts in processes of processing and packaging the glyphosate granules are reduced by the aid of one-time forming of the glyphosate water-soluble tablet, the problem of difficult absorption of tail gases and dusts is solved, the screening process is omitted, the reworking rate is reduced, the environment-friendly safety is improved, the glyphosate water-soluble tablet belongs to a novel glyphosate preparation, and simultaneously the packaging, transporting and storing costs are greatly lowered.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of glyphosate water-soluble tablets and preparation method thereof.
Background technology
Glyphosate is the maximum and the fastest interior Assimilation and conductivity type weed killer herbicide of growth rate of global sales, and be accompanied by glyphosate genetically modified crops succeed in developing and promote the use of and energy shortage causes sowing and the popularization of biofuel crop, for the production of glyphosate provides new opportunity.
The glyphosate formulation of generally using now is 41% glyphosate isopropylamine salt water solution, 30% ammonium salt aqua and soluble powder.Because the aqua effective component content is low, bad metering, packing, storage, cost of transportation height, uneconomical.Number of patent application is a kind of soluble solid dosage typed salt of glyphosate of 02119480.7 disclosure of the Invention, solved the problems referred to above, but because reaction time is long in the soluble solid medicament form production process, dust is large, contaminated environment, also harmful to operating personnel's health.
