Abstract: |
Using cyanuric chloride as the precursor,the S-triazine derivatives of 6-(dibutylamino)-1,3,5-triazine-2,4-dithiol(DB) and 6-anilino-1,3,5-triazine-2,4-dithiol (AF) were synthesized,and their structures were characterized by Fourier transform infrared spectroscopy and differential scanning calorimeter.Besides,the influences of DB and AF on vulcanization behaviors of CM were investigated.The results showed that,with increasing of temperature,scorch times and optimium cure times of CM/DB and CM/AF systems shortened gradually;meanwhile maximum torque and minimum torque decreased correspondingly.Results of curing kinetics research revealed that,the apparent activation energies of CM/DB and CM/AF systems were 33.3 and 71.6 kJ·mol-1 respectively,indicating that curing rate of CM/AF system was affected greater by temperature than that of CM/DB system.When cure temperature was kept at 160 ℃,the cured elastomers had better mechanical performance. |
