Description
Technical field
The present invention relates to a kind of agricultural chemicals suspension agent.
Background technology
Acibenzolar, benzo (1,2,3) thiadiazoles-7-carbothioic acid-S-methyl esters, english common name: acibenzolar, be a kind of plant disease-resistant activator, suitable for crop has paddy rice, wheat, vegetables, banana, tobacco etc.Under recommended dose to crop safety, without poisoning.Powdery mildew, rust, downy mildew etc. can be prevented.
Tridemorph, English common name: Tridemorph, No. CAS: 81412-43-3.Chemical name: 2,6-dimethyl-4-tridecyl morpholine.Tridemorph is mainly used in preventing and treating powdery mildem of cereals and sigatoka, to other fungal disease, as: white, red, brown root rot, powdery mildew, the coffee eye spot of bamboo grows; The cake disease that tealeaves is right; The electricity such as melon powdery mildew and the powdery mildew of flowers and trees has good preventive effect.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent (Suspensionconcentrates, be called for short SC) also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, be under surfactant and other promoter effects, the former medicine being insoluble to or being insoluble in water be distributed in water, form uniform and stable thick suspension system.Because its dispersion medium is water, thus suspending agent to have cost low, to produce, the feature such as storing and use safety, and easily mix with water, easy to use.Compared with taking organic solvent as the formulations of pesticide of medium, there is the advantages such as little to environmental influence of poisoning be light.
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 agricultural chemicals suspension agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Agricultural chemicals suspension agent, comprises the raw material of following weight percentage: Acibenzolar 15-25%; Tridemorph 15-25%.
Agricultural chemicals suspension agent, is made up of following materials by weight percentage: Acibenzolar 15-25%; Tridemorph 15-25%; Butyl glycol ether 4-8%; Attapulgite 0.05-0.15%; Surfactant 4-8%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, is made up of 70-90 weight portion disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of 10-30 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate, English name: SodiumLaurylDiphenylEtherDisulfonate, No. CAS: 7575-62-4.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

(Phenylmethyl)phenyl]-.omega.-hydroxy-poly(oxy-1,2-ethanediyl)Nonionicsurfactant。
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, former being mainly used in suppresses the corrosion in linear cutter and galvano-cautery, sludge in softening working groove, is used as rust-inhibiting additive in low-speed WEDM production process.In prior art, do not have and this raw material is used for any technology enlightenment that agricultural chemicals reagent plays dispersion moistening effect.
Agricultural chemicals suspension agent easily produces a large amount of bubble in process, may affect metering and the packaging of preparation.Therefore, the defoamer of 0.1-0.7wt% can be added in formula, the method such as ultrasonic, vacuum defoamation can certainly be adopted in process of production to carry out froth breaking, and not need to add defoamer.Mould inhibitor or pH adjusting agent can also be added according to actual needs in formula.
Agricultural chemicals suspension agent of the present invention can adopt the general method in this area to be prepared, and one is ultramicro grinding method (also known as wet grinding), and another kind is coacervation (also known as hot melt-dispersion method).
Ultramicro grinding method:
(1) according to formula, Acibenzolar, tridemorph, butyl glycol ether, attapulgite, surfactant 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≤4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Suspension refers to that former powder of dispersion keeps the ability of suspension time length in suspension, usually represents with suspensibility.A good suspending agent, should have good storage stability, namely higher suspensibility.
Agricultural chemicals suspension agent of the present invention has higher suspension rate, stable during long-term storage, for preventing and treating plurality of plant diseases especially powdery mildew, the rust in cereal, vegetables, fruit tree, flowers and other crops.
Embodiment
