| Abstract: |
| The application of the composite carbon powder with aphanitic graphite as the main
component in solid tire compounds was studied. The results showed that by using the composite carbon
powder to replace 50% of carbon black N660 and N330 in the intermediate compound and tread compound
of the solid tire，respectively，the physical properties of the test formula compounds were comparable to the
original formula compounds，and the thermal conductivities were improved. Compared to the original formula
solid tire，the test formula solid tire had lower heat generation，better durability and longer service life. The
composite carbon powder had good thermal conductivity and could effectively reduce the tread temperature
of solid tire，therefore，it could be used as a heat-conducting reinforcing filler in solid tire compounds. |
