Embodiment 1

[0030] This embodiment proposes a kind of run-flat tire, comprises the tire body that is made of tread 1, carcass, buffer layer, bead, as figure 1 As shown, in the structure of the tire body, the tread 1 is bonded and synthesized by double-layer rubber layers, and an explosion-proof layer 2 made of high-molecular explosion-proof material is sprayed on the outer rubber layer 1-1, and the inner rubber layer 1 -2 is provided with several capsule cavities 3, and the capsule cavities 3 are provided with leak-tight glue.

[0031] In this embodiment, four groups of side-by-side pattern surfaces are annularly arranged along the outer rubber layer. The pattern surfaces are respectively two groups of outer pattern surfaces 4 and two groups of inner pattern surfaces 5 arranged between the two groups of outer pattern surfaces 4. The pattern surface 4 and the inner pattern surface 5 are separated by several V-shaped grooves 6 to form several pattern blocks, and the explosion-proof layer 2 ...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is that the rubber composed of perfluoroether rubber, nitrile rubber and natural rubber accounts for 50% of the total tread rubber.

Embodiment 3

[0037] The difference between this embodiment and Example 1 is that, in parts by weight, the tread rubber formula includes: 20 parts of perfluoroether rubber, 16 parts of nitrile rubber, 10 parts of natural rubber, 35 parts of reinforcing filler, accelerator 3.5 parts, 1.2 parts of vulcanizing agent, 1 part of vulcanization accelerator, and 0.8 parts of adhesion promoter.

Abstract

The invention discloses an explosion-proof tire which comprises a tire body composed of a tread, a tire body, a buffer layer and a tire bead, wherein the tread is a rubber composition prepared by taking rubber as a matrix and adding with auxiliary materials such as a reinforcing filler, an accelerant, a vulcanizing agent, a vulcanization accelerator and an adhesion promoter; an explosion-proof layer made from high polymer explosion-proof materials is sprayed on the surface of the tread; a plurality of capsule cavities are formed in the tread and filled with leak-repairing glue. With the adoption of a manner of combining the explosion-proof layer, the capsule space and the tread rubber, the explosion-proof layer is sprayed on the surface of the tread, so that the elasticity of the tread surface is increased, and the acting force of a sharp object on the tread rubber is relieved; and moreover, the capsule cavities are formed in the tread rubber, when the sharp object pierces the capsule cavities to reach the tire body, the leak-repairing glue in the capsule cavities reacts with air so as to perform curing, and the condition that running safety is threatened by leakage of high-pressure gas in the inner liner is avoided.

Description

technical field [0001] The invention relates to an anti-explosion tire, in particular to an anti-explosion tire for cars and belongs to the field of tire design. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. When the vehicle is running, the tire tread will directly contact the ground. A puncture is usually caused by a sharp object piercing the tire tread to the carcass, causing the tire inner liner to be punctured, and the high-pressure gas in the inner liner to leak rapidly. If a tire blows out while the vehicle is running at high speed, it is extremely dangerous. Therefore, a blown tire is also an important hidden danger that threatens driving safety. [0003] The existing patent document CN200984930 (a kind of anti-explosion tire for automobile front wheels, 2007-12-05) discloses a design of double rims and double tires, that is, the front wheel assembly is formed by com...
