| Abstract: |
| Three kinds of metallic passivator，including EDTA-2Na，NaCA and STPP，were added into skim rubber through three kinds adding processes.The effect of adding process of metallic passivator on the curing characteristics，physical properties and thermo oxygen aging properties of skim rubber was investigated.The results showed that with metallic passivator，the curing characteristics and physical properties of skim rubber were changed slightly，but the thermo oxygen aging properties were improved significantly.Through adding NaCA or EDTA-2Na before skim serum coagulation，the thermo oxygen aging properties and thermal stability of skim rubber were improved，and better results would be obtained by adding STPP in mixing process. |
