Description
Technical field
The present invention relates to a kind of improved formulations of butyl inner tube sizing material resistant to thermal aging, belong to tyre technology.
Background technology
The inner tube of a tyre is commonly called as inner tire.Refer to for keeping inner pressure of tire, the annular elastic tube with tyre valve.Valve cock is used
To inflate and air is kept certain pressure in the inner tube of a tyre.The inner tube of a tyre should have good air-tightness, heat resistance, elasticity, ageing-resistant
Property and less permanent deformation.Typically manufactured with butyl rubber.
Butyl rubber is one kind of synthetic rubber, is synthesized by isobutene and a small amount of isoprene.Typically it is used in making
Inside automobile tire and auto sound articles for use.With the name of environmental protection, popularization replaces pitch to present butyl rubber comprehensively.
The self-closing better performances of butyl glue inner tube of a tyre colloid, with high-air-tightness.Air pressure is high in more than 8MPA after the loading for the inner tube of a tyre
Air-tightness carcass reduces the natural seepage of gas, inflation frequency reduction more in use than the natural gum inner tube of a tyre, under steam also more fuel-economizing.
Butyl glue inner tube of a tyre high temperature tolerance is more superior than the natural gum inner tube of a tyre, and automobile is in long-term run at high speed, and tyre cavity temperature is very high, makes
The interior quick autovulcanization of tire rubber, influence service life butyl glue inner tube of a tyre is more resistant to aging, and use time is longer.
