บทคัดย่อ (EN): rubber nanocomposites based on natural rubber (NR), BaSO4 nanoparticles (BN) and carbon black (CB) were prepared by dry mixing. The morphology. Mechanical properties and thermal properties of these nanocomposites were investigated. Test results revealed that BaSO4 nanoparticles modified with sodium stearate exhibited outstanding reinforcement due to its homogenous dispersion in the NR matrix and shows stronger polymer-filler interactions. Significant increase in tensile strength (26%) and tear strength indicated the reinforcement capability of BaSo4 nanoparticles. Thermal studies indicated that retention in tensile strength and modulus at 300% elongation are well improved in the presence of 5BN along with 30CB. Thermo-oxidative ageing and TGA traces showed that incorporation of 5BN into black filled matrix shifts the onset of degradation from 319.5 to 326°C, whereas maximum degradation temperature was unaffected. The degradation in acid was found to decrease with the addition of nano BASO4 in carbon black filled NR composites. The weight change measurements and studies on adhesion of compound to mild steel plates support the enhancement in properties. SEM micrographs show additional evidence for the better dispersion of nano BaSO4 and carbon black in natural rubber matrix by the incorporation surface modifiers.
