Description
Technical field
The present invention relates to formulations of pesticide manufacture field, is related to the formulations of pesticide containing MTI-446, and in particular to a kind of agricultural chemicals suspension agent containing MTI-446 and preparation method thereof.
Background technology
21st century, the use of pesticide are still one of Main Means that the mankind struggle with disease pest and weed in agricultural production.With a large amount of uses of pesticide, substantial amounts of organic solvent causes pollution to environment, with the continuous enhancing of people's environmental consciousness and security knowledge, direction of the formulations of pesticide towards water baseization, spheroidizing, slow-releasing, multi-functional, Labor-saving and environment-friendly type is developed, and particularly the dosage form of suspended emulsion is increasingly by favour and the attention of people.Agricultural chemicals suspension agent (SC) is a kind of environment amenable environment-protection pesticide dosage form with water as medium, is the higher suspension shape system disperseed homogenizing in aqueous medium and formed by a kind of water-fast solid-state active compound and a kind of oily liquids active compound and various auxiliary agents.Suspending agent is a three-phase mixture, and discontinuous phase is scattered in water phase, i.e. oil/water row Emulsion and is thoroughly dispersed in the solid phase of water phase.There is suspending agent, emulsifiable concentrates for agricultural chemicals and wettable powder pollution and murder by poisoning because of organic solvent and dust to environment and operator is such as avoided, storing safety, with higher biological activity etc., is shown one's talent in water-based aerosol.
The physicochemical property of MTI-446：Appearance white powder, without special odor, molecular formula C7H14N4O3
Structural formula is：
Relative molecular mass：202.21 (based on calendar year 2001 world relative atomic masses)
Biological activity：Parasite killing
Fusing point (DEG C)：107.5
Dissolubility (g/L, room temperature)：Water 40, is insoluble in the organic solvents such as hexamethylene, dimethylbenzene.
Density：1.425g/cm3
Stability：It is chronically exposed to perishable under sky air and heat and wet environment
MTI-446 have tag, stomach toxicity and root absorbability is strong, quick-acting high, lasting period long 3-4 are all（Theoretical lasting effect 43 days）, the features such as insecticidal spectrum is wide, and have excellent preventive effect to sucking insect, and show very high insecticidal activity in very low dosage.It is mainly used in preventing and treating aphid in Semen Tritici aestivi, Oryza sativa L., Cotton Gossypii, vegetable, fruit tree, the various crop such as Nicotiana tabacum L., leafhopper, plant hopper, thrips, aleyrodid and its resistant strain, simultaneously coleoptera, Diptera and Lepidoptera, Diptera, beetle mesh and total wing mesh insect are had efficiently, and the sanitary insect pests such as cockroach, Coptotermes formosanus Shtrari., housefly are had efficiently.Which, was registered in the countries in Asia with Korea as representative, this country and European Countries in Japan's introduction later in 1993.
Suspending agent is the higher suspension shape system disperseed homogenizing in aqueous medium and formed by a kind of various auxiliary agents of water-fast solid-state active compound.The dispersion effect of the suspension emulsion of foreign study exploitation is substantially better than the country, but price is high, and the country technically needs to be broken through.
The main Hefei Xingyu Chemical Co., Ltd at home of the domestic research with regard to MTI-446 at present has made with regard to a kind of guadipyr and dinotefuran and its preparation and applied research, and has applied for patent, and number of patent application is 201210499882；A kind of imidaclothiz and MTI-446 compounded pesticides, number of patent application 201310166119 are reported in patent；Report that the dinotefuran insecticide of compounding has good potentiation in this two parts of patents.
It is an advantage of the current invention that：MTI-446 is prepared into environment-friendly pesticide novel form suspending agent as efficient pesticides of new generation（SC）, reduce the organic solvent used by traditional cream preparation, it is possible to reduce environmental pollution, reduce the toxicity to operator.
The technical problem to be solved in the present invention is to provide the MTI-446 suspending agent that a kind of stable in properties, crystal is not grown up, the invention solves the problems that another technical problem be to provide the preparation method of MTI-446 suspending agent.The present invention has screened a kind phosphate ester class dispersant, improves adhesive force of the effective ingredient MTI-446 to Target crops, while preparing stable suspension system.The even particle size distribution of the MTI-446 suspending agent of the present invention, between 3-5um, suspending agent has good stability mean diameter, and suspensibility all reaches more than 96%, medicine show on crop blade face it is high open up and cohesiveness, anti-rain drop erosion；Good fluidity, hot/cold storage have good stability, and after heat storage, suspensibility is more than 95%；Easily topple over, do not stick bottle wall, room temperature topples over rear residue<0.8%, residue is toppled in heat storage<1.0%.And obtained MTI-446 suspending agent keeps stable in production and product storage period and does not separate out crystal.
The present invention innovative point be：
1st, with the suspension emulsion that new dispersant and active compound combination forming properties are more prominent.Flash-point is high, and suspensibility is high, reaches more than 96% suspensibility, and nonflammable explosive, environmentally friendly, product stability is good, and crystal is not separated out during storing.
2nd, phosphate ester surfactant has protective effect to MTI-446, and obtained suspending agent is good to the selectivity of crop target, and killing rate is high.3rd, the polyoxyethylene ether glycidyl ether phosphoric acid salt dispersant is hydrophilic high polymers, there is between polymer and plant leaf surface certain cementation, so that the anti-rain drop erosion of pesticide, while extend the time of staying of the effective ingredient MTI-446 on crop, so as to notable potentiation.
4th, the polyoxyethylene ether glycidyl ether phosphoric acid salt dispersant is water miscible, so good penetrability, product cost is low, and easy to package, the market competitiveness is strong.
5th, it is inclusion property colloidal suspending agent that the phosphate terpolymer is formed, so pesticide animal migration in soil is little, subsoil water is not polluted, production and application safety, without dust, environmentally friendly.
6th, application of the invention will bring good economic benefit to enterprise.
