MECHANISTIC STUDY OF THE ROLE OF ONE-COMPONENT RESINS IN RUBBER-TO-BRASS BONDING

by PATIL, PANKAJ YADAV

Abstract (Summary)
It is known that the adhesion between rubber and brass-coated steel cords is enhanced by using resins as adhesion promoters. Experiments were carried out using a squalene liquid rubber modeling approach in the laboratory to study the effect of resins on the chemistry of the vulcanization reaction. The formation of new intermediates during vulcanization and changes in chemical concentrations with reaction time was studied by analyzing the squalene reaction mixtures using Gel Permeation Chromatography (GPC). Also, the effect of resins on the surface of sulfidized brass cords was studied by analyzing the adhesion layer’s elemental composition using the Energy Dispersive X-ray Spectroscopy (EDS) and Secondary Ion Mass Spectrometry (SIMS) characterization techniques. The changes in surface morphology of the adhesion layer with reaction time were monitored by Scanning Electron Microscopy (SEM). In this work, a new mechanism is proposed for the role of resins in the improvement of initial and aged adhesion performance between rubber and brass-coated steel tire cords.
