Influència de l'activitat superficial dels diferents components d'una formulació de cautxú en la reacció de vulcanització

by Vidal Escales, Eduard

Abstract (Summary)
SUMMARY: The study of the vulcanization in the presence of fillers shows the carbon black surface influence on the vulcanization reaction and specially its surface activity component. These studies have been opened to other parameters like the microstructure of the carbon black surface. Results show the activation effect of the vulcanization reaction at higher surface activity and specially at higher polar component. To improve the following of vulcanization reaction it has been developed a new analytical HPLC methodology. The same process on the carbon black surface has been studied by ToF-SIMS, and it has been demonstrated to be a useful technique to follow the vulcanization reaction. Taking in account the significance of surface activity, surface activity of some components like the accelerator and sulfur has been modified by cold plasma polymerization in order to study the effect on the vulcanization and the behavior in the mix. Concerning the accelerator, results show that its possible to modify the accelerator performance without modifying the properties of the rubber goods. Sulfur surface activity treatment results open a new field for surface activity treatments to minimize the blooming effect.
