preparation Embodiment 1

[0043] 1.6% Thiamdone Suspension

[0044] The content of each component (by weight) is 1.6% of the original drug of thiamycin, 10% of dispersant sodium lignosulfonate, 2% of thickener xanthan gum, 2% of stabilizer catechol, and defoamer silicone oil 1%, penetrant silicone 2%, antifreeze ethylene glycol 3%, Ph value 6, add deionized water to 100%. After mixing, ball mill in a ball mill for 2-3 hours, so that the diameter of the material is all below 5 μm.

preparation Embodiment 2

[0046] 20% thiamdone suspension

[0047] Each component by weight is 20% of the original drug of thiamydone, 10% of sodium lauryl polyoxyethylene sulfate as a dispersant, 3% of a thickener hydroxymethyl cellulose, and a stabilizer of 2.5% of butyl glycidyl ether, Defoamer II-ethylhexanol 1%, antifreeze glycerol 3%, pH adjuster appropriate amount to make the pH value of suspension agent 7, add deionized water to 100%. After mixing, ball mill in a ball mill for 2-3 hours, so that the diameter of the material is all below 5 μm.

Abstract

The invention relates to a benziothiazolinone water suspension and a preparation method thereof. The benziothiazolinone water suspension is prepared from the following components by weight percentage: 1.6-50% of benziothiazolinone, 0.3-5% of defoamer, 10-20% of wetting and dispersing agent, 0-5% of penetrating agent, 0.3-5% of thickener, 10-80% of water, 1-10% of anti-freezing agent and pH regulator which adjusts the pH value to 6.0-9.0.

Description

technical field [0001] The invention belongs to the technical field of bactericides, and more particularly relates to a novel thiamdone aqueous suspension agent and a preparation method thereof. Background technique [0002] Benziothiazolinone, other names are: bactericide, chlortrimazole, belongs to organic heterocyclic compounds, is a kind of high-efficiency, low-toxicity, broad-spectrum, systemic antiseptic, anti-mold fungicides, with bactericidal spectrum It has the characteristics of wide range, low recurrence rate, resistance to rain erosion, no toxic and side effects to humans and animals, and has a significant control effect on plant rot, root rot, anthracnose, downy mildew and other fungal diseases. Common formulations are 0.8%, 1.5% water emulsion. This is the earliest new variety of pesticides with independent intellectual property rights in my country. It was exclusively developed by Shaanxi Xi Dahuate Technology Industrial Co., Ltd. and officially registered in...
