Abstract

The invention discloses a novel magneticfluid sealant and belongs to the technical field of lubrication and sealing of precise parts. The novel magneticfluid sealant is characterized by being composed of nanoscale ferromagnet particle powder, an additive and carrier liquid, the nanoscale ferromagnet particle powder is composed of nanoscale carbonyl iron powder and nanoscale ferroferric oxide powder, the additive is composed of petroleum sodium sulfonate, 18 amido propylamine, diethyl ethanolamine and oleic acide poxy-ester, and the carrier liquid is composed of silicon chloride oil and dimethyl silicone oil. The oil-based novel magneticfluid sealant is excellent in temperature resistance, pressure resistance and durability. The novel magneticfluid sealant can be applied to various vacuum devices, propeller shafts of ships and warships and water turbine shafts to play a role in effective sealing and lubrication and has the advantages of being low in friction, low in energy consumption, free of leakage and the like. Even if the temperature of a sealed portion is higher than 90 DEG C and the linear speed of a magneticfluid shaft is 26 m/s, long-term effective sealing can be realized.
