摘要：
Hollow glass balls (HGB) were used as functional hollow filler and the end carboxyl liquid butyronitrile rubber (CTBN) was as thickener and toughening agent, as well as the methyl hexahydrophthalic anhydride and 2-ethyl-4-methylimidazole were used as curing agent and accelerator and were added to the epoxy resin. This mixtures were stirred and defoamed by the rotation-revolution mixer, and then the EP/CTBN/HGB ternary composites were obtained through the curing process of temperature programming. The sound insulation performance of the composites is also improved by adding CTBN and HGB, and the average sound transmission loss value (average STL) of the EP/CTBN composites is enhanced by 115% comparing with that of neat EP. The average STL of the EP/CTBN/HGB composite with 30% HGB is further improved by 30%. The EP/CTBN/HGB composites possess more excellent sound insulation performances than the EP/CTBN/GB composites under the same conditions. © 2019, Editorial Board of Polymer Materials Science & Engineering.
