Problems solved by technology

However, the characteristics of the kneaded product are greatly affected by the content of pesticide active ingredients, especially the following disadvantages: the granulation ability of granular wettable agents with high content of pesticide active ingredients is significantly reduced
However, in the method of blending bentonite, the alkalinity of bentonite can easily cause the decomposition of the active ingredient of the pesticide. Therefore, the scope of the active ingredient of the pesticide is obviously limited.
In addition, the granulation method of the above-mentioned conventional granular composition is greatly affected by the content, type, and characteristics of the pesticide active ingredient, and does not always have sufficient granulation properties.

Embodiment 1

[0041] A mixture of 4 parts of butylbencarb adsorbed to 5 parts of white carbon ink, 3.5 parts of badan hydrochloride, 2 parts of polyvinyl alcohol, and 85.5 parts of high-purity quartz powder (medium volume diameter 7.2 μm) will be heated and melted at 60 ° C. After being pulverized by a type pulverizer, put it into a desktop double-screw mixer (manufactured by Ikeda Chemical Co., Ltd.), add about 15% of distilled water, mix for 5 minutes, and install a sieve with an aperture of 1.0 mm. RG-5M manufactured by the company) was granulated. After drying at 60°C, sieve with a 12-24 mesh sieve to obtain granules.

Embodiment 2

[0043] A mixture of 4 parts of butylfencarb adsorbed to 5 parts of white carbon ink that will be heated and melted at 60°C, 3.5 parts of albutan hydrochloride, and 0.5 parts of sodium alkyl sulfate (trade name of Takemoto Oil & Fat Co., Ltd.: New Calgen WG-6) , 2 parts of polyvinyl alcohol, 85.5 parts of high-purity quartz powder (equal volume diameter 7.2 μ m) pulverized with an impact mill, put into a desktop double-screw mixer (manufactured by Ikeda Physical and Chemical Company), add about 15% of distilled water, Mix for 5 minutes, install a sieve with a hole diameter of 1.2 mm, and granulate with an extrusion granulator (RG-5M, manufactured by Kikusui Seisakusho Co., Ltd.). After drying at 60°C, sieve with a 12-24 mesh sieve to obtain granules.

Embodiment 3

[0045] A mixture of 16 parts of butylbencarb adsorbed to 15 parts of white carbon ink, 14 parts of badan hydrochloride, 2 parts of α-starch, and 53 parts of high-purity quartz powder (medium volume diameter 7.2 μm) will be absorbed by impact at 60 ° C. After being pulverized by a type pulverizer, put it into a desktop double-screw mixer (manufactured by Ikeda Physical and Chemical Co.), add about 20% of distilled water, and mix for 5 minutes. RG-5M manufactured by the company) was granulated. After drying at 60°C, sieve with a 12-24 mesh sieve to obtain granules.

Abstract

A granulation composition having the granulation properties improved without being affected by the content, type or nature of a pesticidal active ingredient, and a process for its production, are provided. <??>A granular composition which comprises a pesticidal active ingredient and a highly pure quartz powder as essential components and which is obtained by an extrusion granulation method. A process for producing the granular composition, which comprises blending a pesticidal active ingredient and a highly pure quartz powder as essential components, and granulation by an extrusion granulation method. As compared with conventional ones, the granulation properties can be improved without being affected by the content, type and nature of the pesticidal active ingredient or the prescribed grain diameter of the granular composition.

Description

technical field [0001] The present invention relates to novel granular compositions having excellent granulation properties. Background technique [0002] In most cases, pesticides can be processed into powder, granule, wettable powder, emulsion, SC, EW, etc. before application. Among them, the powder and granule are applied directly or with a spreader, while the emulsion, wettable powder, SC, and EW are mainly diluted with water according to the specified concentration and then spread. [0003] The powder is obtained by pulverizing the active ingredient of the pesticide, or absorbing it by a highly oil-absorbing powder to form a powder, and adding a physical property enhancer as needed, and processing it into a powder. In order to spread directly with the spreader, when filling the spreader with chemicals and further spreading the chemicals, the powder is flying, and there is a problem that affects the health of the operator. [0004] For this reason, in recent years, att...
