The third is that amiloride has excellent performance, but is expensive. At present, the price of amiloride is about 10 times that of glyphosate, and its output cannot meet the market demand. Mixing the two can reduce the cost of medi...

Abstract

A special auxiliary agent for glyphosate-picloram compound water aqua is composed of the following substances (by weight): linear alkylbenzene sulfonates (LAS), fatty alcohol polyoxyethylene ether, N-lauroyl-L-glutamic acid, alkyl sulfonate, glyceryl monostearate, alkyl polyether, a dispersing agent NNO and deionized water. A preparation method of the auxiliary agent comprises the following steps:firstly mixing LAS and fatty alcohol polyoxyethylene ether, uniformly stirring and then adding glyceryl monostearate to obtain a material a; then adding alkyl polyether into deionized water, stirringand dissolving and then adding N-lauroyl-L-glutamic acid and alkyl sulfonate, and adding the above material a to obtain a material b; and finally adding the dispersing agent NNO into the material b to obtain efficient special auxiliary agent for glyphosate-picloram compound water aqua. The auxiliary agent of the invention has a good weeding effect, also has insecticidal and sterilization efficacy, is environmentally-friendly, will not be agglomerated, is convenient to use, has a simple process, and is suitable for industrial production.

Example Embodiment

[0017] A preparation method of a special auxiliary agent for glyphosate and familial acid compound water agent, which is characterized in that it comprises the following steps:

[0018] Step 1: Mix LAS and fatty alcohol polyoxyethylene ether, stir evenly, add stearic acid monoglyceride, stir at 20-60°C for 4-6 minutes to obtain material a;

[0019] Step 2: Add the alkyl polyether to deionized water, stir to dissolve, add lauroyl glutamic acid and alkyl sulfonate, stir evenly, add the above material a, stir and disperse for 15 minutes to obtain material b;

[0020] Step 3: Add the diffusing agent NNO to the material b, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain the special auxiliary agent for the high-efficiency glyphosate and amlpicolinic acid compound water agent.

Example Embodiment

[0021] Specific implementation of the present invention: Example 1:

[0022] Take the following weight material: mix 5% LAS that is linear sodium alkylbenzene sulfonate and 15% fatty alcohol polyoxyethylene ether into the reaction kettle, stir well and add 1% stearic acid glycerin Ester, stir at 50℃ for 5 minutes, then add 5% alkyl polyether and water to it, stir to dissolve, add quantitative 5% lauroyl glutamic acid, 5% alkyl sulfonate, stir and disperse for 15 minutes, Finally, add 2% diffusing agent NNO to the product, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain a special additive for high-efficiency glyphosate and amlpicolinic acid compound water.

[0023] Viscosity determination of the prepared high-efficiency glyphosate and pyridine acid compound water special additives:

[0024] Instrument: NDJ-79 rotary viscometer (Jiangsu Tongjun Technology Instrument Co., Ltd.);

[0025] Test temperature: room temperature;

[0026] Rotor: No. 1 rotor, speed: 12 rpm;

[0027] Using a rotary viscometer, the viscosity of the special additives for high-efficiency glyphosate and pyridine acid compound water agent was 270mPa.s.

[0028] Surface tension measurement:

[0029] Instrument: Contact angle/surface interfacial tension tester (Shanghai Xuanyi Chuangxi Industrial Equipment Co., Ltd.)

[0030] Test temperature: room temperature -45℃

[0031] Measurement method: platinum ring method

[0032] The contact angle/surface interfacial tension tester was used to measure the surface tension of the special additives for high-efficiency glyphosate and pyridine acid compound water agent, which was 18.2mN/m.

[0033] pH measurement:

[0034] Weigh 1.0g of high-efficiency glyphosate and pyridine acid compound water agent special additives into a beaker, add deionized water to 100g, stir evenly, measure the pH value with a pH meter, and measure high-efficiency glyphosate and ammonia The pH value of the special additive for clopyralic acid compound water agent is 5.6.

[0035] Foaming test: Use a 250mL volumetric flask to weigh 200g of tap water, add 1g of glyphosate and aclopyridine acid compound water agent special auxiliary product, turn it upside down 30 times, place it on a horizontal table, and observe the foam height after 1 minute , The foam height of the special auxiliary agent for high-efficiency glyphosate and amlpicolinic acid compound water agent was measured to be 18mL.

Example Embodiment

[0036] Example 2:

[0037] Mix 12% LAS that is linear sodium alkyl benzene sulfonate and 18% fatty alcohol polyoxyethylene ether into the reaction kettle, stir well, and add 3% glycerol monostearate, at 50℃ Stir for 5 minutes, then add 8% alkyl polyether and water to it, stir to dissolve, add quantitative 8% lauroyl glutamic acid, 7% alkyl sulfonate, stir and disperse for 15 minutes, and finally diffuse 3% Add NNO to the product, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain a special additive for high-efficiency glyphosate and apicolinic acid compound water.

[0038] According to the test method of Example 1, the high-efficiency glyphosate and pyridine acid 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.
