Description
Technical field
The present invention relates to a kind of agriculture chemical compounding suspending agent.
Background technology
Thiacloprid, chemical name: (3-((6-chloro-3-pyridyl base) methyl)-1,3-thiazoles quinoline-2-subunit) cyanamide, No. CAS]: 111988-49-9.Thiacloprid (Thiacloprid) former medicine is developed cooperatively by Bayer Bitterfeld GmbH agro-chemical companies and Japanese Bayer agro-chemical companies, is novel chloro nicotinic insecticide.The mechanism of action of thiacloprid and other conventional pesticides different.It mainly acts on insect nerve and engages caudacoria, by being combined with nAChR, and interference insect nervous system normal conduction, cause the obstruction of neural channel, cause a large amount of accumulation of acetylcholine, thus make insect exaltation, general spasticity, paralysis and dead.There is stronger interior suction, tag and stomach poison function, there is no cross resistance with common insecticides as pyrethroid, organic phosphates and carbamates, thus can be used for resistance management.
Pyridaben, chemical name: the 2-tert-butyl group-5-(4-tert-butyl group benzylthio)-4-chlorine pyridazine-3-(2H) ketone, No. CAS: 96489-71-3.Efficiently, broad spectrum acaricides, without interior absorption, tetranychid, Panonychus citri, unguiculus mite are closed to planting property of the food evil mites such as goitre mite and all have obvious control efficiency, and if to ovum mite, become mite all effective, to becoming, the mobile phase of mite is also effective.Be applicable to citrus, apple, pears, hawthorn, cotton, tobacco, vegetables (except eggplant) and ornamental plants.As during for preventing and treating the blister mite such as citrus and European red mite, pears and hawthorn, all can use (for using when improving control efficiency preferably at average every 2 ~ 3, leaf) in the evil mite emergence period, 20% wetting powder or 15% missible oil are diluted to 50 ~ 70mg/L (2300 ~ 3000 times) spraying to water.Safety interval is 15 days, namely within first 15 days, discontinues medication in results.
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 agriculture chemical compounding suspending agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Agriculture chemical compounding suspending agent, comprises the raw material of following weight percentage: thiacloprid 10-20%; Pyridaben 10-20%.
Agriculture chemical compounding suspending agent, is made up of following materials by weight percentage: thiacloprid 10-20%; Pyridaben 10-20%; Ethylene glycol 4-8%; Xanthans 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: Sodium Lauryl Diphenyl EtherDisulfonate, 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

24o.English name: .alpha.-[tris (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.
Agriculture chemical compounding suspending 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, thiacloprid, pyridaben, ethylene glycol, xanthans, 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.
Agriculture chemical compounding suspending agent of the present invention has higher suspension rate, stable during long-term storage, can prevent and treat pest, as tea lesser leafhopper and Aleurocanthus spiniferus.
