AI Technical Summary

Problems solved by technology

The anti-flying additives of water suspensions are prone to poor hard water resistance, flocculation and precipitation at low temperature during the spraying process of anti-flying agents, and similar problems will also occur when using different pesticide formulations, especially in the spraying of anti-flying agents. When the spray concentration is high, the flocculation and sedimentation phenomenon is more obvious

preparation example Construction

[0027] The preparation method comprises the following steps: batching according to the mass percentage of each component, and stirring evenly at 40-60°C to obtain the anti-flying additive.

[0028] When in use, the anti-flying additive is mixed with Thididiuron Diuron aqueous suspension and used for anti-flying spray.

Embodiment 1

[0030] At a temperature of 55°C, 4 parts of fatty alcohol polyoxyethylene ether, 2 parts of silicone polyoxyethylene ether, 5 parts of phenylethylphenol polyoxyethylene ether, 2 parts of calcium alkylbenzenesulfonate, N- 2 parts of cetyl amido betaine, 1 part of tetradecyl dihydroxyethyl amine oxide, 5 parts of alkyl glucoside 1214, 6 parts of sodium dodecylbenzenesulfonate, 5 parts of alkyl ethyl sulfonate, 4 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 2 parts of fatty alcohol polyoxyethylene ether sulfonate, 2 parts of isooctyl alcohol polyoxyethylene ether phosphate and 60 parts of water are mixed and stirred evenly to obtain the anti-flying additive. The anti-fly additive is light yellow or yellow transparent liquid.

Embodiment 2～8

[0032] Embodiments 2-8 are the same as Embodiment 1, the difference is the selection of raw material composition and process parameters, as shown in Table 1 below.

Abstract

The invention discloses a low-temperature-resistant and hard-water-resistant antifly additive, which belongs to the field of pesticide additives. The raw materials include phosphate surfactants, sulfonate surfactants, sulfate surfactants, betaine and water. The present invention can improve the stability of the anti-flying agent, prevent the aggregation and precipitation of the agent, has excellent permeability and dispersibility, and is suitable for use in environments with low temperature and high water hardness.

Description

technical field [0001] The invention relates to an anti-flying auxiliary agent, in particular to an anti-flying auxiliary agent resistant to low temperature and hard water, and belongs to the field of agricultural chemical auxiliary agents. Background technique [0002] Aerial control is an effective method of spraying pesticides on a large area and in a short period of time to reduce the population density of insects by aircraft. Aerial control requires professional chemicals and auxiliaries that are compatible with aircraft. As far as aerial defense additives are concerned, emulsifiable concentrates, suspension concentrates, and dry and wet powders have been studied more at present, but research on aerial defense additives for water suspension concentrates is less. The anti-flying additives of water suspensions are prone to poor hard water resistance, flocculation and precipitation at low temperature during the spraying process of anti-flying agents, and similar problems w...
