Abstract The new environment-friendly insulating medium C₆F₁₂O has good potential to apply in medium and low voltage equipment due to its excellent environmental properties and good insulation performance. In order to evaluate the reliability of long-term safe and stable of C₆F₁₂O/N₂ gas mixture in the equipment, it is necessary to study the compatibility between C₆F₁₂O/N₂ gas mixture and sealing rubber. In this paper, the compatibility of C₆F₁₂O/N₂ gas mixture with NBR is studied by using thermal acceleration method. The composition products of gas mixture and the morphology properties of nitrile Butadiene Rubber (NBR) are revealed based on fourier transform infrared spectrometer and scanning electron microscope respectively. Meanwhile, the formation path of gas decomposition products is simulated based on density functional theory, and the interaction process between NBR and C₆F₁₂O molecules is calculated. It is found that NBR rubber is incompatible with the C₆F₁₂O/N₂ gas mixture at temperatures higher than 90℃. There exists chemical reactions between NBR and C₆F₁₂O/N₂ gas mixture, resulting in the generation of gaseous byproducts including C₃F₆, NF₃ and CS₂ and the precipitation of while crystal particles on the surface of NBR. The theoretical calculation also shows that the increase of temperature can promote the decomposition of NBR molecules, and the gas-solid reaction between C₆F₁₂O and NBR tends to form new substances. The study results can provide important theoretical and technical guidance for engineering application of the C₆F₁₂O/N₂ gas mixture.

Key words： C₆F₁₂O/N₂ gas mixture nitrile butadiene rubber (NBR) material compatibility density function theory (DFT)
