Abstract
The invention relates to a slow release agent for pesticide granules. The slow release agent comprises the following raw materials in percentage by weight: 1%-20% of urea-formaldehyde resin, 1%-30% of starch, 1%-30% of a polyvinyl acetate emulsion and the balance of water. 1%-10% by weight of the slow release agent is added into the granules. The invention further discloses a preparation method of the compound slow release agent and a way of adding the slow release agent into the granules; the preparation method and the addition way comprise the following steps: mixing the urea-formaldehyde resin, the starch, the polyvinyl acetate emulsion and the water, shearing to prepare a colloidal flowable fluid for later use, slowly adding the compound slow release agent after shearing and mixing into coating equipment with granules for uniform coating, and finally drying to obtain the granules with slow release performance. The slow release agent can remarkably prolong the duration of the pesticide granules, reduce the pesticide applying frequency and lower the labor intensity.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of sustained release agent for granular pesticide.
Background technology
Crops are in process of growth, often can be subject to various disease pest and weeds, in order to alleviate, control or the generation of prevention disease pest and weed, people often can give crops use of insecticide, bactericide or weed killer herbicide, enhancing along with people's environmental consciousness, the share of the green pesticide forms such as granule has replaced in the past traditional missible oil gradually, the formulations such as wetting powder, yet often there is drug effect deviation in conventional pesticide granule, lasting period is not long, need the repeatedly shortcoming of dispenser, so just, make agricultural chemicals access times increase, consumption increases, so repeatedly, a large amount of use agricultural chemicals, not only can increase drug cost, and also can affect to environment.
In order to solve short problem of granular pesticide lasting period, it is physics or chemical method that people adopt pesticide slow-release technology, agricultural chemicals is stored in pesticide processing product, agricultural chemicals can slowly be discharged, and reach the object that extends the agricultural chemicals lasting period, as microcapsule granule now etc., yet the current technology content of these formulations is higher, working condition is difficult to be controlled, and equipment is complicated, production cost is also very high, unsuitable spread.
Summary of the invention
The object of the present invention is to provide a kind of stable performance, the granule sustained release agent of reliable in quality.
Another object of the present invention is to provide the using method of above-mentioned composite sustained release agent in granule.
Technical scheme: a kind of sustained release agent for granule, it is comprised of the component of following percentage by weight: Lauxite 1%-20%, starch 1%-30%, polyvinyl acetate emulsion 1%-30%, water surplus.
Wherein, described urea-formaldehyde resin is urea and the 37% formalin linear urea aldehyde oligomer that polycondensation obtains under the catalysis of acid or alkali.
Described starch is one or more the combination in Rhizoma Nelumbinis starch, corn starch, glutinous rice starch, sweet potato starch, wheaten starch, potato starch.
Described polyvinyl acetate emulsion is vinyl acetate one ethylene copolymerization emulsions, the combination of one or more in vinyl acetate one acrylate copolymer emulsion, vinyl acetate one maleic anhydride copolymer emulsion, vinyl acetate one NMA copolymer emulsion.
The using method of sustained release agent of the present invention in granule is: first by proportioning, Lauxite, starch, polyvinyl acetate emulsion and water are mixed to do agglutination can streaming flow standby through shearing, again the good composite sustained release agent of this shear-mixed is slowly joined in the coating equipment in sugar production line that granule is housed and carry out even dressing, last again through being drying to obtain the granule with sustained release performance.
Sustained release agent of the present invention is applied to, in granule, have the following advantages.
1, product cost is low, and technique is simply easy to implement.
2, each composition safety, the low toxicity of composite sustained release agent, meet environmental requirement.
3, be applied in granule, slowly discharge, can significantly improve the lasting period of granular agricultural chemical, reduce spraying times, reduce labour intensity.
Embodiment
Below in conjunction with embodiment, content of the present invention is described in further detail, in embodiment, mentioned content is not limitation of the invention, material prescription select to suit measures to local conditions and on result without substantial impact.In these embodiments, unless otherwise indicated, all percentage is all weight percentage.
