In this work an analysis of influence of process parameters on a process of making of modifiers for road marking materials based on carbon nanotubes was performed. A possibility of creation of a wide concentration range of the carbon nanotubes im polymer-CNT masterbatchesby a coagulation precipitation method was shown.An effect of various precipitants on quality of the modifiers and actual nanocarbon content of the nanotubes were researched. Concentration limits of a creation of the modifiers are based on petroleum resin were substantiated. Identified in this work, it is necessary to consider a partial solubility of wax in most precipitants, and mainly in a mix of xylene and a precipitant when predicting an actual concentration of carbon nanotubes in the resulting composite. An influence of a nature of the different modifiers on a road marking materials resistance to abrasion was studied. It is shown that the highest wear resistance can be achieved by a direct introduction of carbon nanotubes in a polymer film-forming of the road marking. The choice of the most technologically and operationally suitable nanocarbon modifier was described.
