The modified CeO2 was prepared by a chemical surface modification method. The action of CeO2 powders in EPDM composites contain 10 phr modified clay was studied. The effects of content and surface modification of CeO2 powders on the properties of the EPDM composites containing 10 phr modified clay rubber was discussed. The results showed that the mechanical, volume resistivity and thermal properties of EPDM rubber filled with the modified CeO2 increased by loading of modified CeO2. And the tensile strength of EPDM composites containing modified CeO2 is higher than that with the unmodified CeO2. The surface of modified CeO2 powders had a hydrophobic organized layer which could increase interface cohesion with the rubber and dispersity in rubber resulting in exerting reinforcement effect. The effect of coagent on the physical and thermal properties of EPDM rubber composites was studied. The results showed that the physical and thermal properties of EPDM rubber composites increased with the addition of the coagent due to the increase of the crosslinking density. J. VINYL ADDIT.

Methylethylsilicone rubber (MESR)/methylphenylsilicone rubber (MPSR) blends were cured with 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. The curing characteristics, morphology, thermal behaviors, mechanical properties at different temperatures, radiation resistance, and thermal aging resistance of the MESR/MPSR blends were investigated. The results show that a high MPSR content could decrease the optimum curing time and improve the scorch safety. Dynamic mechanical analysis revealed that the glass-transition temperature of the blends increased slightly with the addition of MPSR. Scanning electron microscopy showed that MESR and MPSR had good compatibility in the blends. Thermogravimetric analysis indicated that the thermal stability of the blends increased with increasing quantity of MPSR. The blends had excellent mechanical properties at low temperatures. However, these properties were significantly reduced when the temperature was increased. Moreover, changes in the mechanical properties decreased with increasing MPSR content at high temperatures, especially at temperatures higher than 100 C. In addition, the radiation resistance and thermal aging resistance of the blends increased with increasing MPSR content.

“…Among various modification methods, adding heat‐resistant additives is an efficient way to improve the heat‐resistance of silicone rubber. Metal oxides,3–5 such as ferric oxide (Fe 2 O 3 ) and cerium oxide (CeO 2 ), can be used as heat‐resistant additives and suppress the oxidative degradation of side chains of polysiloxane to improve the heat‐resistance of silicone rubber. However, metal oxides are easy to agglomerate because of their high surface energy.…”

By means of the wet chemical surface modification, the surface of Fe 2 O 3 was modified by vinyltrimethoxysilane (VTMS). Infrared spectroscopy (IR) was used to investigate the structure of the modified Fe 2 O 3 , and the result showed that VTMS has been attached onto the surface of Fe 2 O 3 . Effect of VTMS concentration on the active index of the modified Fe 2 O 3 was also studied, and the result indicated that the active index of the modified Fe 2 O 3 increases with the increase of VTMS concentration and the optimal concentration of VTMS is 12 wt %. The effect of the modified Fe 2 O 3 on the tear strength of silicone rubber before and after aging was studied and it was found that in comparison with the unmodified Fe 2 O 3 the addition of the modified Fe 2 O 3 results in the significant increase of the tear strength before ageing because of the increase of the crosslinking density of silicone rubber. The tear strength of silicone rubber filled with the modified Fe 2 O 3 after ageing is higher than that with the unmodified Fe 2 O 3 , indicating that the modification of Fe 2 O 3 can improve the heat-resistance of silicone rubber owing to the fine dispersion of the modified Fe 2 O 3 in silicone rubber.
