Benefits of technology

This patented technology allows us to create highly concentrated liquid solutions that are easy to store over time at room temperature while maintain their effectiveness through diluting them into smaller sizes. These liquids may contain active ingredients like pigments or other substances needed during agricultural applications such as herbicidal agents. They will stay consistently evenly when stored under different conditions from those they were made beforehand due to factors like weather changes or equipment wear out.

Problems solved by technology

This patented technical problem addressed in this patent relates to reducing the content of potentially dangerous chemical substances called organochlorine compounds during pesticidial compositions containing these agents without causing negative health effects associated with exposure thereto.

Abstract

The invention discloses a hyperdispersant for pesticide. In a general formula, an M part comprises styrene, vinyltoluene, ethyl styrene, methoxy styrene and phenoxy styrene; an N part comprises various kinds of acrylic polyether ester and methacrylic polyether ester; an O part comprises acrylic acid ester containing tertiary amino group; and a P part comprises acyclic acid, methacrylic acid, butenedioic acid and maleic anhydride. The invention also provides a preparation method and application of the hyperdispersant. The hyperdispersant provided by the invention is applied to a pesticide suspension agent (SC) and is low in price, so that the cost of a sub-nano pesticide preparation is low. Therefore, the demand on original pesticide can be greatly reduced, and the pollution to environment and poison brought by production of original pesticide of the pesticide are greatly reduced; and in addition, poisonous residue for soil due to use of pesticide can be greatly reduced, and pesticide residue of crops can be reduced.
