Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of corrosion-resistant and high-temperature resistant oil sump seal rubber material
Material.
Background technique
Engine oil leakage main harm is loss machine oil, causes to waste, serious to may cause machine oil deficiency and then cause
Engine is impaired.Instead of oil leak does not cause for this, because it is insufficient caused to have leaked later engine oil pressure.Since most of vehicles do not have
Organic oil level shows, and there is a situation where unconsciously machine oil to occur lower than normal position, and engine oil pressure deficiency causes
Accident.Bottom-end gasket is used for engine sump tank, plays the role of sealing.Oil sump is the lower half portion of crankcase, again
Referred to as lower crankcase.Its effect is closed crankcase, as the shell of oil storage tank, prevents impurity from entering and collecting and stores by sending out
The lubricating oil that each friction surface of motivation flows back to, disperses partial heat, prevents ravine lubricating oil from aoxidizing.Oil sump mostly by sheet metal punching press and
At;Shape is more complicated general using cast iron or aluminium alloy moulding by casting.It is internal equipped with steady oil baffle, to avoid garage
The oscillation of pasta caused by when vehicle jolts, which swashs, splashes, and is conducive to the precipitating of impurity of lubricant, in addition, oil sump bottom lowest part is also equipped with
Purge cock.With the development of highstrenghtpiston, the oil sump through injection molding is increasingly by vast production firm
Pro-gaze, since plastic shaping is simple, moulding is easy, and traditional gasket type sealing ring has been abandoned by more and more manufacturers, usually exists
Plastic oil pan upper end setting straight trough is cooperated with sealing ring, mostly uses sulfurized nitrile rubber as sealing ring, due to butyronitrile
Rubber is softer, causes sealing position intensity and oil sump intensity inconsistent, will lead to oil sump after stress in weakness
Position breakage oil leak.With good sealability.A kind of good gasket must be able to keep its close within longer period
The ability of envelope.When bolt screws, gasket is simultaneously radially extended or is wriggled simultaneously by pressure, is let out so as to interface occur
Leakage, so gasket Ying Yougao anti-creep ability.With high compactness.There is gasket high compactness can prevent to permeate
Leakage, i.e., cause medium to leak into low-pressure side anti-height with higher by the micro chink of gasket from high-pressure side because of pressure difference
Mild resistance to chemical attack.
