| Abstract: |
| In this study，the formulation design and performance research of fluororubber compounds
were carried out. In order to obtain the compound with excellent oil resistance and wide damping temperature
range that met the requirements of ultra high voltage（UHV） single-column shunt reactor. The vulcanization
characteristics，physical properties，thermal stability and damping property of the fluororubber compound
were improved by adjusting the vulcanization system，acid absorbent and filler system. The results showed
that when bisphenol AF was used as curing agent for fluororubber compound，the comprehensive properties
of the compound were the best when the bisphenol AF amount was 2. 4 phr. Calcium hydroxide as acid
absorbent had a great influence on the vulcanization degree and unsaturated bond content of the fluororubber
compound，and its optimum amount was 9 phr. The compression set of the fluororubber vulcanizate decreased
obviously by the combination of barium sulfate and silicon carbide. However，barium sulfate could shield the
acid absorbent to a certain extent；therefore，the amount of acid absorbent should be increased appropriately
when barium sulfate was applied. The obtained fluororubber vulcanizate in this study could withstand high
temperatures above 400 ℃，and the damping temperature range was － 25 ～ 70 ℃，showing good thermal
stability and wide damping temperature range，which met the requirements of UHV single-column shunt
reactor under service conditions. |
