Development and oil resistance of HNBR-based battery sealing material under high temperature environment
Oil-immersed cooling system has been widely used in energy storage system,which requires the sealing materials to be resistant to oil,temperature and aging.In this work,the oil resistance under high temperature of hydrogenated nitrile butadiene rubber(HNBR)reinforced by carbon black N220 with different contents(mass fraction)was studied.Swelling experiments in 10#and 15#hydraulic oils were carried out at 100℃,125℃and 150℃,respectively.The mass change rate and transport coefficient of HNBR were calculated at different temperatures and media.The results show that the expansion degree of HNBR increases gradually with the increase of carbon black N220,but the diffusion coefficient and permeability coefficient of oil working medium decrease gradually.With the increase of temperature,the expansion degree of HNBR and the diffusion and permeability coefficients of hydraulic oil increase gradually.Compared with 15#hydraulic oil,HNBR has less mass change and expansion in 10#hydraulic oil environment.
