The invention discloses a kind of water surface floating granule of self-diffusion type and preparation method thereof, belong to pesticide processing field.Component forms: pesticide activity component 0.5 70%, buoyancy auxiliary agent 0.5 60%, water surface spreading agent 0.2 30%, dispersant 0.05 10%, wetting agent 0.1 5%, disintegrating agent 5 20%, filler are supplied.Preparation method: 1) become water outstanding or oily outstanding pesticide activity component sand milling；2) by buoyancy auxiliary agent, water surface spreading agent, dispersant, wetting agent, disintegrating agent and filler mix homogeneously, then with 1) ground slurry mixs homogeneously, adds a certain amount of water and carry out mediating pelletize.The preparation method is that wet method sand milling, without dust in preparation process；The granule prepared enter water disintegrate after particle diameter is little, can form more continuous print film；Add the diffusant of excellent performance so that granule can spread automatically at the water surface, diffusion length and speed and the equal scalable of disintegration rate, and granule runs into barrier and can automatically dodge, and will not assemble, cause poisoning around barrier；It it is a kind of preferably self-diffusion type floating granule preparation.
Description
Technical field
The present invention relates to technical field of pesticide, be specifically related to a kind of floating granule of self-diffusion type and preparation method thereof.
Background technology
The problem that pesticide conventional dosage forms exists, such as the dust pollution in the wettable powder course of processing, the toluene of cream, two
The problems such as toluene gradually expose and are subject to people's attention, and some safety coefficients are high, good in economic efficiency, the formulations of pesticide of Labor-saving
Substituting the conventional dosage forms that those consumptions are big, toxicity is high, environmental pollution is serious, pesticidal preparations is just towards water baseization, granular, slow
Release, multi-functional and Labor-saving direction is developed.
Floating granule is the one of Labor-saving dosage form, and " Labor-saving " has become as the focus of pesticide research and development, big granule, water meter
Face dispersible granule (U granule), fumicants, bait formulation, high concentration granule, film-spreading oil solution etc. use throws the Labor-saving dosage form executed or spread fertilizer over the fields not
The most time saving and energy saving, significantly overcome the risk of environmental pollution that float of mist droplet causes, welcome by peasant household, be referred to as " lazy
People's technology ".
Floating granule be mainly used in paddy field prevent curing the disease, worm, crop smothering and in sewage, prevent and treat a kind of dosage form of the mosquito larva of a tapeworm or the cercaria of a schistosome, and
On preventing and treating rice grub and weeds, there is the performance excellent compared with other dosage form.The advantage of floating granule is similar to big granule, a side
Face, can mix fertilizer or mix soil, and every 667 square metres are directly spread fertilizer over the fields-30 place at 20, it is possible to be diffused into whole automatic uniform
Field, can deserve to be called " natatory intelligence herbicide ", so the agrochemical formulations of high-load effective ingredient is sprinkled into rice
Tanaka, and be that local applies, as effective ingredient can not promptly be spread by fruit granule from throwing the position spread, prevent activity one-tenth
Point release and be uniformly distributed, the effect of pesticide can become not enough, causes rice field phytotoxicity and Local residues, remains in field
Effective ingredient can there is potential danger, crop is produced detrimental effect, such as CN89107067, to disclose a kind of water floatable
Aggregation solid Agrotechnical formulation, the diffusibility being had on water surface only with carbamate pesticide, and do not add
Adding water surface spreading agent, scalability is far not by far up to the mark；CN200810103541 provides a kind of spherical spore of mosquito killing
Bacillus leafing agent, it is that mosquito eradication Bacillus sphaericus ferment filtrate is concentrated by employing membrane concentration method, then carries by porous
Body material adsorbs, then with slow releasing agent combination drying, finally wrap up water-repelling agent, utilize water-repelling agent reach diffusion effect,
It is obvious that diffusion effect is not directly added into diffusant；CN200810143587 provides and prepares floating granule by absorption, weight
Point research concentrates on solvent and uses above problem and cheap inorganic microporous substance adsorber, and water surface spreading agent is not launched phase
The research closed, it is impossible to prepare the floating granule of self-diffusion type of excellent performance.
And on the other hand, compared with conventional dosage forms, floating granule combines the good dispersion of cream, wettable powder storage
The advantage that fortune is convenient and dry suspending agent is easy to use, and there is handling ease, simple to operate when using, time and labour saving prominent excellent
Point.The preparation technology great majority of current domestic floating granule are to use gas flow crushing process, comminution by gas stream preparation process cost height,
Operation is complicated, energy consumption is high, can produce dust in preparation process, pollutes environment.As CN201310043145 describes a kind of performance
Stable, suspensibility is high, and the effective ingredient of reliable in quality is the floating particle agent of penoxsuam and pyrazosulfuron；
CN201310448663 discloses the floating granule that effective ingredient is oxadiargyl；CN201410670721 and
CN201310710822 provides the big granule of paddy field weed-killer float type that diffusion is good；CN201410056541(Sumitomo Chemical
Co., Ltd.) the Waterbourne granular insecticide of a kind of novelty is provided, use specific surfactant package；But they
Common ground is all that preparation technology uses first coarse pulverization comminution by gas stream again, during can produce substantial amounts of dust, pollute environment,
Complex process, energy consumption is high, and cost is high, and after entering water disintegrate, granule film thick, that formed is uneven, it is impossible to prepare the floating of environment-friendly type
Granule.
Summary of the invention
It is an object of the invention to provide a kind of water surface floating granule of self-diffusion type and preparation method thereof, without powder in preparation process
