Description
Technical Field
The invention relates to the field of pesticide spraying, in particular to a pesticide spraying agent.
Background
Pesticide sprays are a pesticide adjuvant that is used to help dissolve pesticides in water and form a more uniform coating on the surface of crops. The pesticide spraying agent can promote pesticide to be adsorbed on the surfaces of leaves and permeate into plants, and improves the utilization efficiency and control effect of the pesticide. Meanwhile, the use of the wetting agent can also reduce the dripping phenomenon during spraying and improve the spraying precision. However, when the existing wetting agent is used, the wetting effect on crops is poor, and the wettability of the crops needs to be ensured through a long-time reaction, so that the spraying efficiency of pesticides is low.
Disclosure of Invention
The invention provides a pesticide spraying agent, which solves the technical problems.
The scheme for solving the technical problems is as follows:
a pesticide spray comprises double-chain cationic surfactant, ammonium lauryl trimethyl methyl sulfate, sodium carboxymethyl cellulose, polyvinyl alcohol, defoaming agent, glycerol and water.
The beneficial effects of the invention are as follows:
the double-chain cationic surfactant has the main functions of improving the wettability of the surface of crops and promoting the contact between the surface of crops and pesticides, thereby improving the adhesion and uniformity of the pesticides. Double-chain cationic surfactant can be combined with the surface of crops through the electropositive ionic part of the double-chain cationic surfactant to form a colloid to increase wettability, so that the surface of crops is more easily coated by pesticides;
The dodecyl trimethyl ammonium methyl sulfate can form a micelle structure in water, so that the wettability is improved, the surface tension is reduced, the wetting agent is easier to contact and diffuse with pesticide molecules, and particularly, a molecular chain of KCMS in water can self-assemble to form a spherical micelle structure. These micelle structures are stabilized by electrostatic interactions of anionic species such as external carboxylic acids with KCMS cations. As KCMS molecular chains in the micelle structure play a role in dispersing pesticide molecules, the surface tension of liquid is reduced, and the wettability is improved. Meanwhile, the micelle structure has higher water retention, and a layer of film can be formed on the surface of the pesticide, so that the adhesive force of the pesticide is increased, and a better wetting effect is realized;
The defoamer molecule typically has a relatively hydrophilic head portion and a relatively lipophilic tail portion. In the presence of the liquid surface, the hydrophilic head of the defoamer molecule faces the liquid center, and the lipophilic tail faces the liquid surface. The molecular arrangement mode can effectively reduce the surface tension and interface energy of the surface of the liquid, so that bubbles or foam molecules are not easy to diffuse to the surface and are not easy to gather on the surface to form foam. In addition, the de-foaming agent can also affect the morphology and stability of the bubbles or foam. When bubbles or foam exist on the surface of the liquid, the molecules of the defoaming agent can form a film on the surface of the bubbles or foam, and the film is inserted into a lattice structure formed on the surface of the bubbles or foam to break or deform the lattice structure, so that the bubbles or foam are eliminated. Meanwhile, the film can also prevent liquid molecules on the surface of the liquid from diffusing to the surface of the bubbles or the foam, so that the bubbles or the foam are shorter in stability time and easier to disappear;
Glycerol is used as a cosolvent, and by utilizing good solubility and hydrophilic property of the glycerol, the glycerol and chemical substances which are not easily dissolved in water (such as certain pesticides, medicines and the like) form a mixture, so that the solubility of the chemical substances in water is improved, namely the dissolution of the chemical substances in water is promoted, and in a mixed solution, glycerol molecules can form hydrogen bonds with water molecules, and can also interact with molecules of other chemical substances which are not easily dissolved in water through electrostatic interaction. These interactions can make the mixture of glycerol and other chemicals as a whole more hydrophilic, thereby increasing the solubility of these chemicals in water. Meanwhile, the glycerol can improve wettability, so that the chemical substances are more easily and uniformly dispersed in water, and in addition, the glycerol can prevent evaporation of water and does not pollute the environment;
And the double-chain cationic surfactant and the dodecyl trimethyl ammonium methyl sulfate both have the function of improving the wettability of the surface of crops, and the combination of the double-chain cationic surfactant and the dodecyl trimethyl ammonium methyl sulfate can further increase the contact area between the surface of the crops and the pesticide; glycerol acts as a co-solvent and allows the chemical to be more easily and uniformly dispersed in water. Therefore, the components cooperate with each other when being matched for use, so that a good synergistic effect can be formed, the performance and the efficacy of the wetting agent are further improved, and the effects of promoting the adhesion and uniformity of pesticides through interaction of various components in the wetting agent are further achieved, so that the wetting time of the wetting agent to crops is shortened, the wetting effect of the crops is ensured, and the pesticide application effect of the crops is further ensured.
On the basis of the technical scheme, the invention can be improved as follows.
Further, the addition ratio of each raw material is as follows: double-stranded cationic surfactant: 2%, ammonium lauryl trimethyl sulfate: 25% sodium carboxymethylcellulose: 10%, polyvinyl alcohol: 5% of a defoaming agent: 5% of glycerol: 4% and the balance of water.
Further, the double-stranded cationic surfactant is dodecyl dimethyl tertiary amine.
Further, 3% -5% of antistatic agent is added during configuration, so that the electrostatic effect is effectively reduced, and the adsorption and conduction effects of the wetting agent are improved.
Further, the antistatic agent is polyacrylamide.
Further, each medicine is mixed according to a certain proportion, heated to a uniform liquid and packaged, and the mixture is diluted to a concentration of 0.3% -0.5% by using pure water when in use.
Further, the wettability of the surface of the crops is improved by the double-chain cationic surfactant, and the contact between the surface of the crops and the pesticide is promoted, so that the adhesion and uniformity of the pesticide are improved.
Further, a layer of positively charged film is formed on the surface of crops through the ammonium dodecyl trimethyl sulfate, so that the wettability of the surface of the crops is further improved.
Further, the polyvinyl alcohol and the polyacrylamide are used as antistatic agents to act together, so that the electrostatic effect is effectively reduced, and the adsorption and conduction effects of the wetting agent are improved.
Further, polyvinyl alcohol is used as a stabilizer, so that a stable colloid system can be formed in the wetting agent, and precipitation or precipitation of the colloid system can be prevented.
