Key words:
Pre-dispersed accelerator NOBS(MBS)-80
The pre-dispersed accelerator NOBS(MBS)-80 makes the scorch time of the compound quite long, the processing safety is very high and the vulcanization is very complete. It can be used alone as the main accelerator in low-sulfur vulcanization, or it can be used in combination with dithiocarbamate or thiuram accelerator, and the resulting vulcanizate has good heat aging resistance and good compression deformation; pre-dispersed accelerator NOBS(MBS)-80 and dithiocarbamate accelerator and thiuram accelerator will significantly reduce the scorch time of the compound. The combination of thiuram TMTM-80 accelerator and pre-dispersed accelerator NOBS(MBS)-80 has a particularly obvious promotion effect of shortening vulcanization time, and has good anti-scorch effect and high crosslinking degree. In low sulfur compound, in the compound containing sulfur alcohol accelerator and thiuram accelerator, the pre-dispersed accelerator NOBS(MBS)-80 can delay scorch.
