preparation example Construction

[0028] Correspondingly, the embodiment of the present invention also provides a preparation method of the above special adjuvant for aviation plant protection. The preparation method of the special auxiliary agent for aviation plant protection of the embodiment of the present invention comprises the following steps:

[0029] Step S01: Weigh the raw materials of each component according to the following component ratios in mass percentages:

[0030] 1%-30% hydrophilic solvent, 1%-30% viscosity regulator, 1%-30% anti-evaporation agent and 0-50% water;

[0031] Step S02: After mixing the hydrophilic solvent and water, adding a viscosity modifier and an anti-evaporation agent in sequence, and performing mixing again.

[0032] Specifically, the type and content of each component raw material measured in the above step S01 are the same as the type and content of each component described in the above-mentioned embodiment of the special auxiliaries for aviation plant protection. In o...

Embodiment 1

[0038] This example provides a special adjuvant for aviation plant protection and its preparation method. The special auxiliary agent for aviation plant protection consists of the following components:

[0039] Glycerin formal 10%, polysaccharide gum 20%, sodium polyacrylate 20%, water 50%.

[0040] The preparation method of the special auxiliary agent for aviation plant protection:

[0041] According to the formula of special additives for aviation spray in Example 1, weigh glycerin formal and water and add them to the reaction kettle to stir evenly, then weigh the polysaccharide gum and sodium polyacrylate with accurate mass and add them in turn, using stirring or homogenizer method Mixing is carried out until a homogeneous and transparent mixed solution is formed.

Embodiment 2

[0043] This example provides a special adjuvant for aviation plant protection and its preparation method. The special auxiliary agent for aviation plant protection consists of the following components:

Abstract

The invention provides an additive specially used for aviation plant protection, and a preparation method and an application of same. The additive is composed of, by mass, 1-30% of a hydrophilic solvent, 1-30% of a viscosity modifier, 1-30% of an anti-evaporation agent, and 0-50% of water. Through synergistic effect of the components in the additive, the additive is larger than 1 in specific gravity and has high boiling point. An aviation plant protection spray has high stability, and is free of problems of precipitation, crystallization, flocculation and spray nozzle plugging in 1 h, and also has moisturizing effect, is anti-volatilization and anti-drifting, accelerates settlement and has good stability. The preparation method guarantees the stability of the additive and is low in production cost; the additive is free of aromatic hydrocarbon solvents, so that the additive is low in toxicity on human and animals, and is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the field of pesticide adjuvants and plant protection, and in particular relates to a special adjuvant for aviation plant protection and its preparation method and application. Background technique [0002] In the current and future agricultural production in my country, labor shortage has become one of the key factors restricting agricultural development. The use of drones for plant protection spraying has significant advantages such as accurate spraying, high operating efficiency, wide application range, less labor, water saving and chemical saving. [0003] With the rapid development of the agricultural plant protection UAV flying defense business, nearly ten million acres of farmland have been sprayed with plant protection UAVs every year. The mechanization and automation of pesticide application has played an important role, which can effectively save agricultural costs and improve the efficiency of prevention and control...
