| Abstract: |
| The acrylonitrile-butadiene-styrene copolymer（ABS）was modified with waste NBR powder（WNBR）and silane coupling agent modified hollow glass beads（HGB），and the effects of addition level of WNBR and modified HGB on the structure and physical properties of composites were investigated.The results showed that，for WNBR/ABS composite，when the addition level of WNBR was low，the compatibility between WNBR and ABS was poor，and interaction between WNBR and ABS was weak.When the addition level of WNBR was 20 phr，the compatibility between WNBR and ABS was better，and the cross section was flat and smooth.WNBR could be used to increase the impact strength of WNBR/ABS composite，but the tensile strength and flexural strength were decreased.For modified HGB/WNBR/ABS composite，modified HGB was finely dispersed with no agglomeration，and uniformly distributed.Modified HGB could be used to increase the tensile strength，flexural strength and impact strength of modified HGB/WNBR/ABS composite when the addition level was less than 5 phr.The comprehensive physical properties of the composite were optimized when the addition level of modified HGB was 5 phr. |
