Description
Technical field
The present invention relates to oil seal technique field, in particular to a kind of high leakproofness toughening polytetrafluoroethyloil oil seals material.
Background technique
Oil sealing (oil seal) is the habit appellation of general sealing element, is briefly exactly the sealing of lubricating oil.It is to use
Carry out the mechanical organ of oil sealing rouge (oil is the most common liquid substance in transmission system, also refers to the meaning of general liquid substance),
The component for needing to lubricate in transmission parts is isolated with power output component for it, is unlikely to allow oil seepage.Static seal and dynamic sealing
(general to move back and forth) is with sealing element oil sealing.
The circular cowling that oil sealing is made of one or several parts, be fixed on the lasso or washer of bearing and with it is another
One lasso or washer contacts form narrow labyrinth clearance, prevent lubricating oil leakage and foreign object intrusion.For being mounted on various machines
In tool equipment, in defined temperature, pressure and different liquids and gases, seal under static or motion state.
The material of oil sealing generally has: fluorubber, nitrile rubber, silicon rubber, ethylene propylene diene rubber, polytetrafluoroethylene (PTFE) etc..
Polytetrafluoroethylene (PTFE) has high and low temperature resistance outstanding, keeps good within the temperature range of -70 DEG C -+260 DEG C
Using elasticity, and there are resistance to ozone, Weather-resistant, preferably makees the sealing gasket in thermomechanical.Because that can be made without any toxicity
It is insulated, insulated product and druggist rubber sundrier.
Polytetrafluoroethylene (PTFE) is with the chemical stability of its height, and extremely strong high- and low-temperature resistance performance is outstanding non-stick, well
Lubricity, excellent electrical insulating property, resistance to ag(e)ing, minimum water imbibition etc. makes it in aerospace, petrochemical industry, machinery
The fields such as industry, electronic apparatus, food industry, weaving have a wide range of applications but also because that there are mechanical performances is poor for they, and line is swollen
Swollen coefficient is big, and creep resistant is poor, and wear resistance is poor, and hardness is low, molding and secondary operation it is difficult the defects of, make its application range by
To certain limitation.Modified frequently with surface in order to improve and overcome the defect of pure polytetrafluoroethylene (PTFE), filling-modified and blending changes
Property etc. means improve its comprehensive performance, wherein especially with it is filling-modified it is the simplest, price is low, effect is good and generally adopted
With.
