Effect of Carbon Nanotube Bundles Combined with Silica on Thermal Conductivity and Mechanical Properties of SSBR
Michelin company developed the first generation of green,fuel-efficient tyres by using silica in 1990s.The addition of silica greatly reduces the rolling resistance of the tire,but there are also some shortcomings and deficiencies that the carbon black tire has not seen.In order to solve this problem,the effects of carbon nanotube bundles(CNTBs)and disordered carbon nanotubes on the machining properties,static mechanical properties,dynamic mechanical properties and electrical conductivity of SSBR composites were studied in this paper.The results showed that the three CNTBs formed a complete network system in the rubber matrix.GT205 reinforced composites have excellent nano-reinforced effect,and the static mechanical properties increase significantly.In addition,due to the excellent orientation and high dispersion of GT205,it's not significantly increase the tanδ of the composite,and the volume resistivity of the CNTBs/SSBR composite is only 1/6500 of that of the control group.And can meet the requirements of the use of tread adhesive conductivity.
