Anti-volatile spray additive as well as preparation method and application thereof

Abstract

The invention provides an anti-volatile spray additive. The anti-volatile spray additive is prepared from the following components in percentage by mass: 20 to 48 percent of vegetable oil, 8 to 40 percent of surfactant, 8 to 40 percent of anti-volatile agent, 3 to 15 percent of sedimentation promoting agent and 0 to 61 percent of solvent. According to the anti-volatile spray additive disclosed bythe invention, the problems that medicinal liquid is easily volatilized in processes of plant protection of unmanned aerial vehicles and spray fog droplet sedimentation of large-sized machines and absorption of the medicinal liquid are solved, and the problems that the sedimentation velocity is low in a spraying process and the sprayed medicinal liquid are easily drifted are improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a drone spraying aid or a large mechanical spraying agent and a preparation and use method thereof. Background technique [0002] With the gradual acceleration of my country's agricultural modernization process, the rural labor force has gradually decreased, and labor costs have continued to rise. Traditional artificial plant protection methods can no longer adapt to the gradual intensification of large-scale agricultural production. In contrast, drones with advantages such as high efficiency and low cost Or large-scale mechanical plant protection has attracted more and more attention, especially in the fields of paddy field pesticide application, special terrain pesticide application, and centralized control and unified control of pesticide application. However, since the water consumption of modern mechanical spraying equipment is 50% to 10% or less of that of traditional me...

Problems solved by technology

[0005] In 2015, Noposion Corporation announced in CN 105010314 A a preparation method of a pesticide diluent mainly composed of a hydrophilic solvent and water, and the remaining components are surfactants and humectants to solve the problem of low-capacity or ultra-low-capacity pesticide diluents. Problems such as precipitation, flocculation, crystallization, volatility, drift, etc., improve the toxicity of existing pesticide diluents and the instability of the diluted pesticide solution system
