Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent, also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, has cost low, the features such as production, storing and use safety, and easily mixes with water, easy to use.
Summary of the invention
For solving the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of thiophanate-methyl and the composite agricultural chemicals suspension agent of Tebuconazole.Be achieved especially by following technical proposals:
Thiophanate-methyl and the composite agricultural chemicals suspension agent of Tebuconazole, comprise the raw material of following weight percentage: thiophanate-methyl 12-18%; Tebuconazole 12-18%.
Thiophanate-methyl and the composite agricultural chemicals suspension agent of Tebuconazole, be made up of following materials by weight percentage: thiophanate-methyl 12-18%; Tebuconazole 12-18%; Surfactant 5-9%; Dipropylene 5-7%; Magnesiumaluminumsilicate 0.05-0.15%; Polymethyl hydrogen siloxane 0.1-0.3%; Sodium salicylate 0.01-0.03%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of succinate sodium 2-ethylhexyl and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, is made up of 40-60 weight portion succinate sodium 2-ethylhexyl and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of 40-60 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

nc
27h
24o.Succinate sodium 2-ethylhexyl, also known as: Aerosol OT, No. CAS: 577-11-7.
PH adjusting agent can also be added according to actual needs in formula.
Thiophanate-methyl of the present invention and the composite agricultural chemicals suspension agent of Tebuconazole can adopt the general method in this area to be prepared, and one is ultramicro grinding method, and another kind is coacervation.
Concrete, described ultramicro grinding method:
(1) according to formula, thiophanate-methyl, Tebuconazole, surfactant, dipropylene, Magnesiumaluminumsilicate, polymethyl hydrogen siloxane, sodium salicylate and water are uniformly mixed pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Thiophanate-methyl of the present invention and the composite agricultural chemicals suspension agent of Tebuconazole have higher suspension rate, stable during long-term storage.Be mainly used in the water prevention rice sheath blight, promote that paddy rice stem is sturdy, resistant to lodging simultaneously; The tall and straight plumpness of blade, photosynthesis is strong, is beneficial to rice milking stage, and how result of the test shows to use paddy rice field of the present invention volume increase between 10%-17%.Field trial shows, has good behaviour in control fringe phase integrated disease false smut, rice kernel smut, brown stain fringe, oriental sesame leaf pinta etc.
Embodiment
Embodiment 1
(1) according to formula, thiophanate-methyl, Tebuconazole, surfactant, dipropylene, Magnesiumaluminumsilicate, polymethyl hydrogen siloxane, sodium salicylate and water are uniformly mixed pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Obtained suspending agent, the liquid of outward appearance thickness homogeneous phase, measure through Malvern laser fineness gage, its average grain diameter (D50) is 3.3 μm.
Table 1: thiophanate-methyl and the composite agricultural chemicals suspension agent formula table unit of Tebuconazole: kilogram
