A novel method for the optimization of sulfur cure systems for rubber using software
The goal of this study was to find a software approach that would make the optimization of the vulcanization system more efficient.
For this purpose, a natural rubber (NR) was mixed with different amounts of elemental sulfur at ambient temperature to produce
rubber compounds. Zinc oxide was treated with an organic accelerator to produce a convenient single material component to use
as additive. The effect of an increasing loading of the surface modified zinc oxide on the cure properties of the sulfur-filled rubber
compounds was subsequently measured at a high temperature in a curemeter. Using a JavaScript program, the cure test results were
processed to develop a highly efficient method for optimizing sulfur cure systems for rubber. All the essential information such as
scorch and optimum cure times, rate of cure, crosslink density changes in the rubber, and chemical curatives requirement at a given
loading of sulfur were subsequently provided for the user. This method removes the need to mix and test the raw rubber with chemical curatives repeatedly to find a compound with ideal cure properties for industrial applications
Ein neues Software-Verfahren zur Optimierung von Schwefelvulkanisationssystemen
Ziel dieser Arbeit war es, einen Softwareansatz zu finden, mit dem sich Schwefelvulkanisationssysteme effizient optimieren lassen.
Zu diesem Zweck wurden aus Naturkautschuk (NR) bei Raumtemperatur Compounds mit verschiedenen Anteilen an elementarem
Schwefel hergestellt. Aus Zinkoxid wurde durch Beschichtung mit einem organischen Beschleuniger ein Einkomponentenadditiv hergestellt. Dann wurde der Einfluss einer zunehmenden Menge dieses Additivs auf die Vulkanisationseigenschaften der schwefelgefüllten Compounds bei hoher Temperatur bestimmt. Mithilfe eines JavaScript-Programms wurden die Ergebnisse der Vulkanisationsversuche verarbeitet, um eine effiziente Methode zur Optimierung des Schwefelvulkanisationssystems zu entwickeln. Der Nutzer erhält
als Ergebnis alle wichtigen Informationen, wie Anvulkanisationszeit, optimale Vulkanisationszeit, Vulkanisationsgeschwindigkeit,
Änderung des Vernetzungsgrades, sowie den Bedarf an Vernetzungsadditiven in Abhängigkeit von der Schwefelmenge. Auf diese Weise können zahlreiche Versuche zur Bestimmung der idealen Compoundzusammensetzung für optimale Vulkanisationseigenschaften
eingespart werden.
