Detailed Description

The following description will further describe a specific embodiment of the anti-pricking type super heat-resistant butyl inner tube with reference to fig. 1. The utility model relates to a prevent pricking type super heat-resisting butyl inner tube of a tyre is not limited to the description of following embodiment.

This embodiment provides a specific structure of a puncture-proof super heat-resistant butyl inner tube, as shown in fig. 1-3, an anti-puncture super heat-resistant butyl inner tube includes:

the inner tube comprises an inner tube body 1, a first inflation cavity and a second inflation cavity, wherein the inner tube body 1 comprises a tire skin layer 5 and a gauze layer 6, and the inner part of the inner tube body 1 is provided with the inflation cavity 2;

a carcass layer 4 bonded to the outer surface of the carcass layer 5; and

an outer rubber sleeve 3 adhered to the outer surface of the outer tire layer 4, and a plurality of grooves 31 arranged on the surface of the outer rubber sleeve 3

As shown in fig. 2, the screen layer 6 includes a double ply cord fabric, and the screen layer 6 is laid on the inner wall of the carcass layer 5 and is integrated with the carcass layer 5.
