| 中文摘要: |
| 为获得满足特高压单柱并联电抗器苛刻耐油性能和宽阻尼温域等的胶料，进行了氟橡胶胶料的配方设计及其性能研究，通过调整硫化体系、吸酸剂、填料体系来提高氟橡胶胶料的硫化特性、物理性能、热稳定性能和阻尼性能。结果表明：双酚AF作为硫化剂用于氟橡胶胶料，其用量为2.4份时胶料综合性能最好；氢氧化钙作为吸酸剂对氟橡胶胶料的硫化程度和不饱和键含量均有较大影响，其最佳用量为9份；硫酸钡/碳化硅并用对减小氟橡胶硫化胶的压缩永久变形作用明显，硫酸钡在一定程度上可屏蔽吸酸剂，因此其应用需适当增大吸酸剂用量；本研究氟橡胶硫化胶可耐400 ℃以上的高温，阻尼温域范围为－25～70 ℃，能够满足特高压单柱并联电抗器在使用工况下对热稳定性和阻尼温域的要求。 |
| 英文摘要: |
| 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. |
