Embodiment 1

[0015] The total weight of each component of the present embodiment is 10kg, and the weight percent of each component is:

[0016] Tebuthiauron technical 20%,

[0017] Wetting agent: Isotridecanyl ethoxylate 0.5%,

[0018] Dispersant: triphenylethylphenol polyoxyethylene ether phosphate triethanolamine salt 2%, sodium styrene acrylate 2%,

[0019] Thickener: sodium carboxymethylcellulose 0.2%,

[0020] Defoamer: Simethicone 0.2%,

[0021] Antifreeze: Propylene Glycol 4%,

[0022] Preservatives: Polyoxymethylene 0.1%,

[0023] Water 71%.

[0024] The preparation method is:

[0025] ①First mix sodium carboxymethyl cellulose and polyformaldehyde with half of the water to form a liquid mixture of sodium carboxymethyl cellulose and polyformaldehyde.

[0026] ② After mixing the rest of the raw materials with the other half of the water, use a sand mill to carry out multiple cycles of wet crushing until the fineness of the particles is 1 micron to 5 microns, so as to obtain a ...

Abstract

The invention discloses a suspending agent of tebuthiuron. The suspending agent of tebuthiuron comprises the following components in percentage by weight: 20 to 50 percent of raw medicament of tebuthiuron, 0.5 to 5 percent of wetting agent, 1 to 10 percent of dispersing agent, 0.1 to 5 percent of thickening agent, 0.1 to 2 percent of defoaming agent, 1 to 10 percent of preservative, and the balance of water, wherein the dispersing agent is one or two of triphenyl ethylphenol polyethenoxy ether phosphate ester triethoxide, alkylphenol polyethenoxy ether sodium sulfonate, triphenylethylene phenol polyethenoxy ether, triphenylethylene phenol polyoxyethylene polyoxy propylene ether; and the wetting agent is fatty alcohol polyethenoxy ether and / or alkylphenol polyoxyethylene succinate sulfonate. The suspending agent is good in dispersibility and fluidity and high in suspension rate and can be directly sprayed or mixed with water in any ratio and then sprayed, so that the suspending agent is conveniently used and does not pollute the environment.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a tebuthiauron suspension and a preparation method thereof. Background technique [0002] Pesticide suspension concentrate is a pesticide dosage form prepared by wet ultrafine pulverization of water-insoluble solid drug, pesticide adjuvant and water. Its advantage is that it can be uniformly mixed and dispersed with water in any proportion, not affected by water quality and water temperature, easy to use, not easy to pollute the environment, and can be sprayed directly or after dilution. It is currently recognized as an environmentally friendly dosage form. [0003] Tebuthiauron (i.e. N-(5-tert-butyl-1,3,4,-thiadiazol-2-yl)-N,N'-dimethylurea) is an indestructible urea Herbicides have good control effects on annual and perennial grasses and broad-leaved weeds, and can be used to control weeds in non-arable land, shrubs in pastures, and grasses and broad-...
