摘要

Zinc salts of ethyl, isopropyl, and butyl xanthates have been prepared in the laboratory. The synergistic effect of these xanthates with zinc diethyl dithiocarbamate (ZDEC) on the vulcanisation of natural rubber was studied at different temperatures. The amount of the three xanthates and ZDEC in the compounds was optimised by varying the amount of ZDEC from 0 to P25 pphr and the xanthates from 0 to 15 pphr. The cure characteristics were also studied. The rubber gum compounds with the three xanthate accelerators and ZDEC were cured at various temperatures from 60 to 150 deg C. The sheets were moulded and properties such as tensile strength, tear strength, crosslink density, elongation at break, compression set, heat buildup, abrasion resistance, and flex resistance were evaluated. The properties showed that the zinc xanthate-ZDEC accelerator system has a positive synergistic effect on the curing and mechanical properties of natural rubber compounds.
