| Abstract: |
| The CR damping compound was prepared by using environment-friendly plasticizers acetyl tri-n-butyl citrate （ATBC），dioctyl sebacate （DOS），di-（butoxyethoxyethyl）adipate （TP-95） and butyl oleate （BO） to replace plasticizer DOP，and using environmental-friendly accelerator 3-methylthiozolidine-thione-2 （MTT） to replace accelerator NA-22，and the properties of the environment-friendly CR damping compound were investigated.The results showed that，the comprehensive properties of the CR compound filled with plasticizer TP-95 or ATBC were similar to the CR compound filled with plasticizer DOP，but TP-95 was much more expensive.Compared with the CR compound filled with accelerator NA-22，the curing rate and crosslink density of the compound filled with accelerator MTT were higher，the heat resistance was better，and other properties were similar.The optimized compound met the customer’s technical requirements，and had been supplied to the domestic and foreign markets. |
