Embodiment 1
[0092] Example 1 A 1% environment-friendly acetamiprid aqueous solution
[0093] Raw material ratio:
[0094]
[0095] Prepared by:
[0096] I. prepare various raw materials for preparing 1kg target product according to formula weight ratio;
[0097] II. Add castor oil polyoxyethylene ether (EL-40), fatty alcohol polyoxyethylene ether (AEO-09), sodium dodecylsulfonate and glycerin into the stirring tank, and inject 2 / 3 of deionized water , stirred at room temperature to dissolve to obtain solution A;
[0098] III. Add acetamiprid to the solution A, stir, and dissolve to obtain solution B;
[0099] IV. Add the remaining deionized water into solution B, stir at room temperature, then add tributyl phosphate, stir gently, let it stand still, and filter to obtain the target product with clear and transparent appearance.
Embodiment 2
[0100] Example 2 A 2% environment-friendly acetamiprid aqueous solution
[0101] Raw material ratio:
[0102]
[0103] Prepared by:
[0104] I. prepare various raw materials for preparing 1kg target product according to formula weight ratio;
[0105] II. Add castor oil polyoxyethylene ether (EL-40), fatty alcohol polyoxyethylene ether (AEO-09), sodium dodecylsulfonate and glycerin into the stirring tank, and inject 2 / 3 of deionized water , stirred at room temperature to dissolve to obtain solution A;
[0106] III. Add acetamiprid to the solution A, stir, and dissolve to obtain solution B;
[0107] IV. Dissolve hydroxyethyl cellulose in the remaining deionized water, add this solution to solution B, stir at room temperature to dissolve; then add tributyl phosphate, stir slightly, stand still, and filter to obtain the appearance of 1kg Clarified, transparent target product.
Embodiment 3
[0108] Example 3 A 3% environment-friendly acetamiprid aqueous solution
[0109] Raw material ratio:
[0110]
[0111] Adopt similar preparation method and steps with embodiment 2, difference is:
[0112] Step IV Dissolve guar gum in the remaining deionized water, add this solution to solution B, stir at room temperature to dissolve; then add silicone defoamer, stir slightly, stand still, and filter to obtain the appearance of 1kg Clarified, transparent target product.

Abstract
The invention provides an environmental-friendly acetamiprid aqua. The environmental-friendly acetamiprid aqua contains the following ingredients in percentage by weight: 1-5% of acetamiprid and 1-10% of action agent A, wherein the action agent A is one or more selected from sulfonic acid group containing anionic surfactant, sulfuric acid group containing anionic surfactant and carboxyl group containing anionic surfactant; preferably, the acetamiprid aqua provided by the invention can also contain an action agent B which is 1-5% the total weight of the environmental-friendly acetamiprid aqua; the action agent B is selected from non-ionic surfactant and / or natural macromolecular surfactant. The invention further provides a method for preparing the preparation. The environmental-friendly acetamiprid aqua provided by the invention does not contain any organic or corrosive solvent, is of a uniform clarified solution in appearance and is stable in long-term placement, and the indoor insecticidal activity of the environmental-friendly acetamiprid aqua is equivalent to that of an emulsified oil preparation with concentration which is the same as that of the environmental-friendly acetamiprid aqua, so that the environmental-friendly acetamiprid aqua provided by the invention is obviously better than emulsified oil preparations and other water-based preparation forms.
Description
technical field [0001] The invention belongs to the field of new formulations of pesticides, in particular to a novel environment-friendly acetamiprid water formulation and a preparation method thereof. Background technique [0002] With the improvement of environmental protection awareness, the requirements for high efficiency and environmental friendliness of pesticide formulations are put forward. Studies have found that for the same pesticide technical, the effectiveness of the pesticide formulation depends on its formulation type and the dispersion state and size of the pesticide particles. Scientific common sense tells us that when other conditions are the same, the smaller the particle size of the pesticide original drug is, the larger its surface area is, and the wider the contact area with plant leaves and pests is, the more fully the drug effect will be, and the amount of pesticide used will be lower. reduce accordingly. [0003] Whether a pesticide dosage form i...
