Example Embodiment

[0025] Example 1: 50% difenoconazole·thiophanate methyl: the content of each component (by weight) contains 30% difenoconazole, thiophanate methyl 20%, wetting and dispersing agent dodecane Base polyoxyethylene ether phosphate 5%, open powder 1%, thickener xanthan gum 0.2%, stabilizer dinaphthol 0.5%, defoamer silicone defoamer 0.2%, antifreeze ethylene glycol 4 %, add deionized water to make up 100%.

[0026] Preparation process: firstly mix difenoconazole and thiophanate methyl, then add the wetting and dispersing agent according to the proportion and stir well, then add the defoamer, thickener, stabilizer, antifreeze and deionization in sequence Add water while stirring, and mill it in a ball mill for 2-5 hours to make the particle size of difenoconazole and thiophanate methyl all below 5um.

[0027] The preparation process of the following examples is similar to this.

Example Embodiment

[0028] Example 2: 50% difenoconazole·thiophanate methyl: the content of each component (by weight) contains 20% difenoconazole, 30% thiophanate methyl, wetting and dispersing agent alkyl naphthalene Formaldehyde condensate sulfonate 7%, thickener sodium carboxymethyl cellulose 0.2%, stabilizer sodium benzoate 0.5%, defoamer n-octanol 0.2%, antifreeze glycerol 4%, plus deionized water to make up 100%.

Example Embodiment

[0029] Example 3: 60% difenoconazole·thiophanate methyl: the content of each component (by weight) contains 10% difenoconazole, thiophanate methyl 60%, wetting and dispersing agent lauryl alcohol poly Sodium oxyethylene ether sulfate 8%, sodium dodecylbenzene sulfonate 3%, thickener polyethylene glycol 0.2%, stabilizer BHT 0.5%, defoamer silicone defoamer 0.2%, antifreeze propylene glycol 4 %, add deionized water to make up 100%.

Abstract

The invention relates to the technical field of pesticide compound fungicidal suspension manufacturing, and in particular to a difenoconazole and thiophanate methyl compound suspension and a preparation method thereof. The difenoconazole and thiophanate methyl compound suspension is prepared from the following componentsin percentage by weight: 5 to 30 percent of difenoconazole, 5 to 70 percent of thiophanate methyl, 0.2 to 2 percent of defoaming agent, 3 to 15 percent of wetting dispersant, 2 to 8 percent of antifreezing agent, 0.2 to 2 percent of thickening agent, 0.5 to 5 percent of stabilizer and the balance of water. Because the difenoconazole and thiophanate methyl are dispersed in a form of fine particles into the water, the difenoconazole and thiophanate methyl compound suspension has a high flash point, does not burn and explode, and is safe to produce, store and use; dust and environmental pollution are less, so the difenoconazole and thiophanate methyl compound suspension is safe for producers, users and the environment; the water is adopted as a matrix, resources are rich, the product cost is low, and the difenoconazole and thiophanate methyl compound suspension is easy to package. For the better understanding of the essence of the invention, the technical content of the invention is elaborated below by using an example, but the content of the invention is not limited thereto.

Description

technical field [0001] The invention relates to the technical field of manufacturing a pesticide compound bactericidal suspension, in particular to a suspension of difenoconazole and thiophanate-methyl and a preparation method thereof. Background technique [0002] Pesticide suspension concentrate is a dosage form developed in the 1970s, and has now become one of the basic processing dosage forms. Suspending agent (SC), also known as water suspending agent, colloidal suspending agent, concentrated suspending agent, is to disperse the original drug which is insoluble or hardly soluble in water into water under the action of surfactant and other additives to form a uniform and stable Coarse suspension system. Since its dispersion medium is water, the suspending agent has the characteristics of low cost, safe production, storage and use, and is easy to mix with water and convenient to use. Compared with the pesticide dosage forms using organic solvents as the medium, it has t...
