Effect of high loading of titanium dioxide particles on the morphology and selected properties of natural rubber-based composites
Abstract
The aim of this work was to prepare and characterize the natural rubber vulcanizates contained different amounts of titanium dioxide particles. At first rubber mixture was prepared using a laboratory two-roll mill and then samples were vulcanized in a hydraulic press. The formulation of rubber mixture and rubber-processing technique is based on our earlier investigations. Materials were obtained at the different titanium dioxide loadings i.e. of 15, 25, 45, 85 parts by weight per hundred parts of natural rubber. This research is focused on the determine the influence of different loadings of titanium oxide particles on the chemical structure, morphology, mechanical and thermo-mechanical properties of natural rubber-based composites. It was found that vulcanizates with different amounts of TiO2 particles possess good characteristic in the terms of all measured properties. The results of Fourier Transform Infrared Spectroscopy (FTIR) analysis showed that the chemical structure of the obtained natural-based composites was not influenced by presence of titanium dioxide particles. The SEM micrographs showed uniform dispersion of TiO2 in the natural rubber matrix. For the higher content of TiO2 in natural rubber the agglomerates of filler appear. The Thermogravimetric Analysis (TGA) showed slightly different thermal stability of obtained natural rubber composites. The Dynamic Mechanical Thermal Analysis (DMTA) showed that prepared materials have similar glass transition temperatures. However, increasing content of titanium dioxide in obtained materials is connected with higher energy loss (higher dissipation of energy) during the mechanical work of material and higher cross-link density of prepared materials
