Micro- and nano- silicone carbide particles are used as heat conductive
fillers of methyl vinyl silicone rubber, and the influence of filler amount, particle size
and the surface treatment of filler on the thermal conductivities and mechanical
properties of silicone rubber are studied. The results show that the thermal
conductivities of silicone rubber are improved, but the mechanical properties are
worse with the increase of the amount of fillers. The composite filled with smaller
sized silicone carbide has a better thermal conductivity than that filled with large
particles in a relatively high filling fraction, and composite filled with different sized
silicone carbide has different mechanical properties at the same filling amount.
Treatment of fillers with coupling agent (KH-560, A-171) has active impacts on the
thermal conductivity but negative impacts on mechanical properties of the filled
silicone rubber. |
