Abstract
Fluorsilicone rubber as a new type of special functional rubber has attracted attention, which combines the advantages of the organic silicone materials and the organic fluorine materials. Herein, we reported fluorosilicone rubber vulcanized at high temperature by the hydrosilylation addition reaction. The silicone oil containing hydrogen in the pendant group and the perfluorocyclobutyl aryl ether (PFCBAE) group in the backbone (S-H-Oil-PFCBAE) was prepared by the hydrolytic polycondensation and ring opening reaction of silane with PFCBAE (M4), octamethylcyclotetrasiloxane (D4), and tetramethylcyclotetrasiloxane (D4H) by the traditional catalysis of concentrated sulfuric acid. And S-H-Oil-PFCBAE was used as the crosslinker to vulcanize fluorosilicone rubber. The mechanical property, the thermal stability, the hydrophobicity, and the solvent resistance of vulcanizates were studied in detail. The result showed that S-H-Oil-PFCBAE could improve the comprehensive performances of fluorosilicone rubber.
