Abstract

The invention provides an anti-drift agent. The anti-drift agent is prepared from one or more of rosin-modified phenolic resin, an acrylic acid polymer, modified alkide resin, hydroxy acrylic resin, oil-soluble phenolic resin and alcohol-soluble phenolic resin. The invention further discloses a spray additive, which is prepared from a solvent and the anti-drift agent. By adopting the spray additive disclosed by the invention, the gasification of fog drops can be effectively retarded, evaporation of the fog drops is restrained, rapid reduction in the sizes of the fog drops can be prevented, and the drifting effect of the fog drops is effectively restrained.

Description

technical field [0001] The invention belongs to the technical field of pesticide adjuvants, and in particular relates to an anti-drift agent for suppressing droplet drift, a spray adjuvant prepared by the adjuvant, and a preparation method and application of the adjuvant. Background technique [0002] As the degree of agricultural mechanization continues to increase, the technology of using aircraft to spray pesticides, herbicides, insecticides and fertilizers on crops has become more and more popular. It can not only achieve rapid and large-scale application of pesticides and fertilizers, but also save a lot of manpower and reduce costs. In the process of aircraft spraying, the drift and surface tension of the droplets are the most important factors affecting the spray effect. Among them, the drift of the droplets is due to the vaporization of the droplets and the evaporation of the solvent, resulting in a smaller volume and lighter weight, which makes the trajectory of th...
