Abstract: The acoustic insulating materials described in this paper are prepared by modified acrylonitrile-
butadiene-styrene copolymer(ABS as basal body and high damping silicone rubber as filler. The mechanica
properties, micro-morphology and acoustic insulating effect of the products with different content of high
damping silicone are tested with the help of electron universal testing machine and scanning electron microscope
(SEM). The results indicate that the heat and sound insulating properties improve with the content of silicon
rubber increasing, while the mechanical properties weaken. In conclusion, the modified ABS resin with 10%
15%o of high damping silicon rubber has best performance in low frequency noise protection
