The low temperature resistant oil sealing of the present invention uses polytetrafluoroethylene (PTFE), calcium hydroxide, the paraffin powder of proper ratio with rubber material
So that fluorubber keeps good mechanical performance.It is added to the filler being made of spray carbon black, thermal cracking carbon black and dibutyl ester, heat
Cracking black carbon is made of a large amount of spherical, oval charcoals and a small amount of welding particle, have grain size is big, specific surface area is small, structure is low,
The features such as being easy dispersion, good fluidity, vulcanization glue elasticity is high, deforms small, low temperature performance well, and stress at definite elongation is high, but stretches strong
Degree and elongation are relatively low；The processing performance of spraying carbon black is good, and extrusion contraction is small, and vulcanizate has the vulcanization with thermal cracking carbon black
Performance similar in glue, elasticity is high, and stress at definite elongation is high, and since the particle specific heat cracking black carbon of spray carbon black is small, reinforcing property wants high
In thermal cracking carbon black, two kinds of ingredients are mixed into the filler collectively as rubber, can effectively enhance the damping property, resistance to low of fluorubber
Warm nature energy and mechanical performance；Dioctyl ester is universal plasticizer, can inhibit precipitation bleed, and low temperature resistance is excellent, three's cooperation
Use resistance to low temperature, mechanical performance and the stability that can be obviously improved fluorubber.Polyphenylene sulfide, hydroxyethyl cellulose, diformazan
Base silicone oil, anti-aging agent, sulphur mutual cooperation can increase the oil resistance of the present invention, stability.Each substance cooperates so that originally
Invention has good resistance to low temperature, oil resistance, mechanical performance and damping property.
