Abstract

The invention belongs to the field of dispersants, and particularly relates to a pesticide dispersant, which comprises, by weight, 10-35% of a polycarboxylic acid dispersant, 4-8% of polyether modified polysiloxane, 20-30% of ethyl acetate, 10-20% of benzenesulfonic acid, 6-10% of CMC and the balance of water, wherein the polycarboxylic acid dispersant is acrylic acid-(methyl) acrylic acid copolyester, and has the molecular weight distribution of 10000-100000. According to the invention, the pesticide dispersant has characteristics of no toxicity, no harm, low sensitivity to pH value, temperature and the like, high dispersion stability and less settling and flocculating; and the polycarboxylic acid dispersant improves the content of solid particles, significantly reduces the viscosity of the dispersion system, has good fluidity under high solid content, reduces the raw material cost, and reduces the equipment wear.

Description

technical field [0001] The invention belongs to the field of dispersants, in particular to a pesticide dispersant. Background technique [0002] Dispersants mainly refer to chemical agents that reduce the viscosity of cement slurry, which are generally surfactants. It can be roughly divided into anionic, cationic and nonionic. In order to reduce the force of mixing solids into liquids, dispersants have been widely used in systems such as paints, molding compositions, coatings, plastic compositions, printing inks, synthetic resins, and pesticides. Solids to be mixed into the liquid medium include, for example, colorants, fillers and fibers. [0003] Prior patents disclosing different structures of phosphate ester dispersants found that certain structures were of limited utility as dispersants over a wide range of applications. If a compound and the system are not fully used, there will be insufficient dispersion due to insufficient interaction with the ambient medium and t...
