Effect of proton radiation on mass loss and thermal properties of additional silicone rubber reinforced with MQ resin

The effect of proton radiation with the energy of 100 keV and 150 keV on thermal properties of additional silicone rubber reinforced with MQ resin by space combined radiation simulator was studied in this paper. The results showed that the aging crackle was produced on the surface of rubber after irradiation and the quantity and size of the crackle increased with the increase of irradiation energy and fluence. There was mass loss of silicon rubber after proton radiation and the mass loss percent increased with the increase of irradiation fluence. The thermostability of silicone rubber increased slightly first and then decreased with the increase of irradiation fluence. The shrinkage of silicone rubber reduced in the temperature range of vitreous state and vitrification transition region af
