Technical Field

[0001] The invention relates to the technical field of barrel mix additives, in particular to a novel rainwater erosion-resistant, wetting-enhancing barrel mix additive. Background Art

[0002] With the increasing refinement of the agricultural industry and the excessive use of pesticides, tank mix efficiency enhancement has become a hot topic in the industry in recent years. The reasons are mainly due to the following points:

[0003] (1) The development of weed resistance and insect resistance has promoted the demand for synergistic tank-mix adjuvants;

[0004] (2) Zero growth policy for pesticides and fertilizers;

[0005] (3) Rural land transfer has promoted the development of large-scale agricultural and agricultural service companies. The next key to large-scale agricultural development is to increase production through planting and plant protection technology;

[0006] (4) Promotion of precision agriculture and new application technologies, such as the large-scale use of drones.

[0007] At present, the tank-mix additives on the market are mainly products containing silicon and non-ionic anionic surfactants. Although these products can improve the wetting and spreading ability to a certain extent, they inevitably bring a series of problems of pesticide damage. How to increase efficiency while greatly avoiding the problem of pesticide damage has always been a pain point in the industry. Summary of the invention

[0008] The purpose of the present invention is to provide a novel rain-resistant wetting and synergistic tank-mixing adjuvant, so as to solve the problem mentioned in the background technology that the tank-mixing adjuvants on the market are mainly products containing silicon and non-ionic anionic surfactants. Although such products can improve the wetting and spreading ability to a certain extent, they inevitably bring a series of problems of pesticide damage.

[0009] To achieve the above object, the present invention provides the following technical solution: a novel rainwater erosion resistant wetting synergistic tank mix adjuvant, comprising the following components in percentage by mass:

[0010] Fatty alcohol 40-50%, polyethylene glycol laurate 35-45%, LIQUITINT@Bright yellow 1.5-5% and ethyl lactate 5-10%, the balance is water. LIQUITINT@Bright yellow is a product of Miliken Company in the United States.

[0011] Preferably, the following components are included in percentage by weight:

[0012] Fatty alcohol 40%, polyethylene glycol laurate 45%, LIQUITINT@Bright yellow 1.5% and ethyl lactate 5.5%, and the balance is water.

[0013] Preferably, the following components are included in percentage by weight:

[0014] Fatty alcohol 45%, polyethylene glycol laurate 40%, LIQUITINT@Bright yellow 2% and ethyl lactate 8%, the balance is water.

[0015] Preferably, the following components are included in percentage by weight:

[0016] Fatty alcohol 50%, polyethylene glycol laurate 35%, LIQUITINT@Bright yellow 3% and ethyl lactate 5%, the balance is water.

[0017] Preferably, the carbon chain number of the fatty alcohol is C6-C18, preferably 8-12 straight carbon chains, and the molecular weight of polyethylene glycol laurate is preferably 350-450.

[0018] A method for preparing a novel rainwater erosion-resistant wetting synergistic tank mix additive comprises the following steps:

[0019] Step 1: Mix fatty alcohol, polyethylene glycol laurate, LIQUITINT@Bright yellow, ethyl lactate and water according to the ratio;

[0020] Step 2: heating during the mixing process, with the heating temperature controlled at 60-80 degrees Celsius to ensure that all components are fully dissolved and mixed evenly;

[0021] Step 3: After mixing evenly, cool the mixture to room temperature to obtain a novel rainwater erosion synergistic additive;

[0022] Step 4: Conduct performance tests on the final product, including spreadability, wettability and permeability, to ensure that all indicators meet the design requirements;

[0023] Step 5: Before product packaging, conduct quality control inspection to ensure that each batch of products meets uniform high standards.

[0024] Preferably, in step 1, the preparation method of LIQUITINT@Bright yellow comprises the following steps:

[0025] S1. dissolving a certain amount of fluorescent dye in an organic solvent, and then stirring at a certain temperature to fully dissolve the fluorescent dye;

[0026] S2, slowly dropping the dissolved fluorescent dye solution into the aqueous solution containing a surfactant, stirring while dropping, so that the fluorescent dye and the aqueous solution are fully mixed;

[0027] S3. The mixed solution is heated and evaporated to remove the organic solvent and excess water to obtain the LIQUITINT@Bright yellow.

[0028] LIQUITINT@Bright yellow is a high molecular polymer colorant developed by Milliken in the United States. It exhibits significant intermolecular forces by combining with fatty alcohols. In tank mix applications, it can significantly improve the adhesion of pesticide dilutions on leaves or pest surfaces, and enhance spreadability and wetting and spreading properties. The polyethylene glycol laurate in the formula acts as an emulsifying agent to ensure that the fatty alcohol can be evenly dispersed and remain stable in water during the dilution process; while ethyl lactate acts as an anti-low temperature agent to ensure that the entire solution is not easy to solidify in a low temperature environment, thereby improving the stability of the product under low temperature conditions.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] By adopting a binary compound solution of C10 fatty alcohol and LIQUITINT@Bright yellow, the wetting, spreading and penetration properties are significantly improved; compared with using C10 fatty alcohol alone, there are significant improvements in rapid wetting and spreading as well as resistance to rain erosion.
