The study is devoted to the issue of evaluating the effect of an emulsifier on the properties of the developed water-based alkyd emulsion intended for dust suppression. The goal was to establish a rational ratio of components in this system according to the following criteria: a decrease in the average droplet size, a decrease in relative viscosity, and an increase in sedimentation stability (emulsion life). The components of the basic composition of the emulsion were alkyd varnish (Resin GF-0123), surfactant (AMP-95), distilled water. To analyze the obtained compositions of the alkyd emulsion, dispersions were prepared containing: alkyd – 55-75% with a step of 5%; Surfactant – 0.1-0.5% in increments of 0.1% of the alkyd content (in-stead). The emulsion was obtained under the following technological parameters: emulsification temperature – 35°C, emulsification speed – 5000 rpm. The analyzed parameters were: dispersion (droplet size), viscosity, life (sedimentation stability) of the emulsion. It has been established that a rational composition, at which the minimum values of dispersion and viscosity are achieved, with a high lifetime at the maximum content of the polymer component, is a composition that includes: 59.7% alkyd, 40% water and 0.3% surfactant. The developed composition makes it possible to obtain an emulsion with a lifetime of more than 1 month, an av-erage dispersion value of 3 µm, and a viscosity of 40 mPa·s.
