Example Embodiment

[0029] Example 1:

[0030] Take the following substances by weight: mix 10% erucic acid PKO, namely erucamide propyl dimethyl tertiary amine, 15% cocamidopropyl betaine, and mix them into the reactor, stir well and add the weighed 8% Lauryl glucoside, stir at 50℃ for 5 minutes, then add 2% polyhexamethylene guanidine and water into it, stir to dissolve, add quantitative 5% tallow amine polyoxyethylene ether, 5% indole butyl Potassium acid, stir and disperse for 15 minutes, finally add 2% polyethylene glycol to the product, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain the special auxiliary for thickening glyphosate and glufosinate-ammonium Agent.

[0031] Determine the viscosity of the prepared thickening glyphosate and glufosinate-ammonium compound water agent special additives:

[0032] Instrument: NDJ-79 rotary viscometer (Jiangsu Tongjun Technology Instrument Co., Ltd.);

[0033] Test temperature: room temperature;

Example Embodiment

[0044] Example 2:

[0045] Mix 12% erucic acid PKO that is erucamide propyl dimethyl tertiary amine and 18% cocamidopropyl betaine into the reaction kettle, stir well and add 7% dodecyl glucoside. ,Stir at 50℃ for 5 minutes, then add 3% polyhexamethylene guanidine and water into it, stir to dissolve, add quantitative 6% tallow amine polyoxyethylene ether, 7% potassium indole butyrate, stir and disperse 15 Minutes later, finally add 3% polyethylene glycol to the product, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain the thickening glyphosate and glufosinate-ammonium compound water agent special additives.

[0046] According to the test method of Example 1, the thickening glyphosate and glufosinate-ammonium compound water agent special additives prepared by this formula have a pH value of 5.7, a viscosity of 320 mPa.s, a surface tension of 16.9 mN / m, and a foam height of 18 mL.

Example Embodiment

[0047] Example 3:

[0048] Mix 8% erucic acid PKO, namely erucamide propyl dimethyl tertiary amine and 20% cocamidopropyl betaine, into the reaction kettle, stir well, and add 6% dodecyl glucoside. , Stir at 50℃ for 5 minutes, then add 2% polyhexamethylene guanidine and water into it, stir to dissolve, add quantitative 8% tallow amine polyoxyethylene ether, 6% potassium indole butyrate, stir and disperse 15 Minutes, finally add 3% polyethylene glycol to the product, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain the special auxiliary agent for thickening glyphosate and glufosinate-ammonium compound water.

[0049] According to the test method of Example 1, the thickening glyphosate and glufosinate-ammonium compound water agent special additives prepared by this formula have a pH value of 5.4, a viscosity of 300 mPa.s, a surface tension of 15.5 mN / m, and a foam height of 19 mL.

Abstract

The invention relates to a thickened type glyphosate and glufosinate compound aqueous auxiliary agent and a preparation technology thereof. The thickened type glyphosate and glufosinate compound aqueous auxiliary agent is prepared from erucic acid KO, cocamidopropyl betaine, tallow amine ethoxylated, indole-3-butyric acid potassium, dodecyl polyglucoside, polyhexamethylene guanidine, polyethyleneglycol and de-ionized water. By adopting the thickened type glyphosate and glufosinate compound aqueous auxiliary agent, a surfactant has a very good weeding effect and also has good insecticidal andsterilization effects; the thickening type glyphosate and glufosinate compound aqueous auxiliary agent has the advantages of environment friendliness, no caking, convenience for utilization; the technology is simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pesticide preparation, in particular to a thickened glyphosate and glufosinate-ammonium compound water adjuvant and a preparation process thereof. Background technique [0002] Glyphosate, the pure product is a non-volatile white solid, insoluble in water and common organic solvents, mainly ammonium or sodium salt, and its salt is completely soluble in water. Glyphosate is a post-emergence systemic non-selective, high-efficiency, broad-spectrum herbicide that kills weeds. By dissolving the waxy layer on the leaf diameter surface of weeds, the drug effect quickly enters the plant conduction system to cause weeds to dry up and die. It has a broad-spectrum , low toxicity, no residue, systemic conduction and excellent killing properties, non-selective to plants, all green plants, including crops. Glufosinate-ammonium was developed in the 1980s. In addition to its herbicidal activity, it also has insecticidal and fungi...
