Description
Technical field
The present invention relates to formulations of pesticide manufacture field, relate to the formulations of pesticide containing tmtd, be specifically related to organic sulfur series bactericidal agent tmtd and prepare the suspension system of former medicine particulate and oil-like emulsions component mixture forms stable suspended emulsion, with and preparation method thereof.
Background technology
21st century, the use of agricultural chemicals is still one of Main Means that the mankind struggle with disease pest and weed in agricultural production.Along with a large amount of uses of agricultural chemicals, a large amount of organic solvents causes pollution to environment, along with the continuous enhancing of people's environmental consciousness and security knowledge, the formulations of pesticide are more and more subject to making a pet of of people towards the formulation of the future development, particularly suspended emulsion of water baseization, spheroidizing, slow release, multi-functional, Labor-saving and environment-friendly type and pay attention to.Agricultural-chemical suspension emulsion (Suspoemulsion, the environment amenable environment-protection pesticide formulation of SE) to be a kind of with water be medium is the higher suspension emulsus system of being disperseed homogenizing by a kind of water-fast solid-state former medicine and the former medicine of a kind of oily liquids and various auxiliary agent and formed in aqueous medium.Suspended emulsion is a three-phase mixture, and discontinuous phase is scattered in aqueous phase, i.e. oil/water row emulsion and be dispersed in the solid phase of aqueous phase completely.Have the advantage of suspension emulsion and aqueous emulsion, as avoided emulsifiable concentrates for agricultural chemicals and wetting powder because organic solvent and dust are to the pollution of environment and operator and murder by poisoning, storing safety, has higher biologically active etc., shows one's talent in water-based aerosol.
The physicochemical property of tmtd: appearance white powder, without special odor, molecular formula C

Structural formula is:
Relative molecular mass: 240.4 (by calendar year 2001 international relative atomic masses)
Biologically active: sterilization
Fusing point (DEG C): 146
Solvability (g/L, room temperature): acetone 80, chloroform 230, ethanol < 10
Relative density: (d204) 1.29
Stability: perishable under being chronically exposed to air, heat and wet environment
Tmtd is a kind of efficient, bactericide that broad spectrum activity has protective effect, be mainly used in the powdery mildew of the crops such as fruit tree, wheat, grape, pseudo-ginseng, tobacco, cucumber, head blight, downy mildew, root rot, epidemic disease, anthracnose, Cereal smut, seedling stage yellow blight etc.Paddy rice seed dressing is better to rice blast, oriental sesame leaf pinta, Tobacco Root maize ear rot effect.
Suspension emulsion is the higher suspension emulsus system of being disperseed homogenizing by a kind of water-fast solid-state former medicine and the former medicine of a kind of oily liquids and various auxiliary agent and formed in aqueous medium.
The dispersion effect of the suspension emulsion of foreign study exploitation is obviously better than domestic, but price is high, and domestic needing technically is broken through.
The main Nantong Baoye Chemicals Co., Ltd. at home of the domestic research about tmtd has at present done the research about thiram wettable powder, and has applied for patent, and number of patent application is 201010157460.7; Report in patent that the mass percent of tmtd is 50% of described thiram wettable powder; Qingdao tension force application is about the patent of thiram tebuconazole compound bactericide, and its number of patent application is 201210564210.4, it is characterized by and is mixed by tmtd and tebuconazole solution, the volumetric ratio of the two is 5-25:1; Within 2013, tension force has applied for thiram carboxin compound bactericide again, the patent No. 201310111679.7, it is characterized in that being mixed into carboxin solution by tmtd solution, and the volumetric ratio of tmtd solution and carboxin solution is 1-2:1.Report that composite Arasan has good synergistic effect in these two parts of patents, have better bactericidal effect than tmtd, Tebuconazole (carboxin) one-pack type.
The invention has the advantages that: tmtd is prepared into environment-friendly pesticide novel form suspending agent (SE) as a kind of organic sulfur series bactericidal agent, reduces the organic solvent that traditional cream preparation uses, and can reduce environmental pollution, reduces the toxicity to operator.Tmtd is a kind of efficient non-internal-absorting leaf surface treatment miticide, tool action of contace poison, and does not have interior absorption, intends finding a kind of germicidal efficiency improving active ingredient tmtd in the present invention by formulation optimization.
The tmtd suspending agent that the technical problem to be solved in the present invention is to provide a kind of stable in properties, crystal is not grown up, another technical problem that the present invention will solve is to provide the preparation method of tmtd suspending agent.The present invention has screened a kind phosphate ester class dispersant, improves the adhesive force of active ingredient tmtd to Target crops, prepares stable emulsion system simultaneously.The even particle size distribution of tmtd suspension emulsion of the present invention, average grain diameter between 3-5um, having good stability of suspension emulsion, suspensibility all reaches more than 96%, and medicine shows high exhibition and adhesivity on crop blade face, anti-rain drop erosion; Good fluidity, hot/cold storage has good stability, and after heat storage, suspensibility is more than 95%; Easily topple over, not glutinous bottle wall, normal temperature topples over rear residue <0.8%, and residue <1.0% is toppled in heat storage.And obtained tmtd suspending agent keeps stable not crystallize out in production and product duration of storage.
Innovative point of the present invention is:
1, the outstanding breast using new dispersant and former medicine to be combined to form performance more outstanding floats agent.Flash-point is high, and suspensibility is high, reaches the suspensibility of more than 96%, nonflammable explosive, environmentally friendly, and product stability is good, at lay up period not crystallize out;
2, phosphate ester surfactant has protective effect to tmtd, and obtained suspending agent is good to the selectivity of crop target, and sterilizing rate is high;
3, this APEO glycidol ether phosphoric acid salt dispersant is hydrophilic high polymers, there is between polymer and plant leaf surface certain cementation, thus make the anti-rain drop erosion of agricultural chemicals, extend the active ingredient time of staying of tmtd on crop simultaneously, thus significantly synergy;
4, this APEO glycidol ether phosphoric acid salt dispersant is water miscible, so good penetrability, product cost is low, easily packs, and the market competitiveness is strong;
5, this phosphate terpolymer is formed is inclusion colloidal suspending agent, so agricultural chemicals animal migration in soil is little, does not pollute underground water, production and application safety, without dust, environmentally friendly;
6, application of the present invention will bring good economic benefit to enterprise.
