Abstract
The invention discloses an automobile intake manifold sealing element and a manufacturing method of the automobile intake manifold sealing element. Through the combined formula of fluororubber, a reinforcing agent, an acid acceptor and the like, the manufactured intake manifold sealing element has excellent oil permeability resistance, and the phenomenon of gasoline leakage cannot be generated even though the sealing element is used for a long time; meanwhile, the sealing element has good high-temperature resistance, cannot be deformed even though used at high temperature for a long time, and is not prone to aging and long in service life.
Description
Technical field
The present invention relates to sealing member and preparation method thereof, relate in particular to automobile inlet manifold sealing member and preparation method thereof, belong to auto parts machinery field.
Background technology
Automobile inlet manifold is the engine apparatus to cylinder head delivering fuel/air mixture, intake manifold of the prior art adopts silicone rubber seal more, but because siloxane main chain has handiness, therefore still penetrable organosilicon sealing ply of the gasoline of some amount.Along with the enhancing of social environment consciousness, gasoline perviousness also comes into one's own further, needs thus to explore a kind of new infiltrative sealing material of more resistance to gasoline.
