Description: The influence of new modifiers of adhesion on the technologi cal properties of the unfilled elastomer compositions based on synthetic isoprene rubber SKI-3 is investigated. Synthesized adhesion promoters constitute silica acid fillers modified with cobalt, nickel, and a combination of cobalt and nickel. This fillers contain are duced number (compared with industrial cobalt stearate) of ions of metals of variable valence on the surface. The samples were investigated by roentgenofluorescsence analysis on wave x-ray fluorescence spectrometer Axios (PANalytical, Netherlands) to establish the quantitative composition of the adhesion modifiers. Tests are carried out to determine the dependency of the change of Mooney viscosity of rubber mixtures, relaxation processes, occurring in volume of an elastomer matrix, and the time to reach the optimal degree of vulcanization of the investigated dosages of the adhesion promoters and amounts of metal ions on their surface. The type and dosage of the synthesized promoters of adhesion of rubber to the brass plated steel cord are established that improve the technological properties of the unfilled elastomer compositions. It is revealed that the introduction of rubber mixt ures based on SKI-3 cobalt-containing modified silica acid fillers with 7.3 and 9.3 wt % allows obtaining elastomeric compositions with similar properties to the compositions containing industrial cobalt stearate.
