【Abstract】 The engineering research on low heat built-up and highly thermally conductive rubber composites for tire applications was carried out. The experimental sample was prepared by using a small inner mixer,and the properties of the sample were compared with those of the sample prepared by using open mill mixing process and the reference sample provided by tire manufacturer. The test results showed that the properties of the sample prepared by inner mixer reached the requirements of tire applications. The compound filled with carbon nanotubes and nano aluminum oxide produced by large scale continuous single stage production process at low temperature showed significantly improved thermal conductivity and low heat build-up. When this thermally conductive compound was applied as tire base compound,the endurance of the finished tire was excellent.更多还原
