Sedan outer tire patch

Abstract

The invention discloses a sedan outer tire patch. The patch is round; the bottom of the patch is an arc-shaped surface which protrudes downward. The patch comprises a patch body, wherein the top surface of the patch body is provided with a polishing layer, a low-temperature vulcanized rubber layer which is not vulcanized and a protection film in sequence from bottom to top; a vulcanized layer is arranged on a bottom surface. The patch body is made of waste tire sidewall rubber. The sedan outer tire patch is simple in structure and reasonable in design, and can be tightly fitted to an inner wall of an outer tire; the patch has enough strength and is stuck with the inner wall of the outer tire to form a whole body by utilizing the low-temperature vulcanized rubber layer; the patch is not easy to fall off and is durable; the patch body is made of the waste tire sidewall rubber, so that wastes are utilized, resource wastes are avoided, and environment protection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of tire repair, in particular to a car tire patch. Background technique [0002] The basic structure of the existing tire patch is generally a rectangular film, in which nylon threads or short steel wires are embedded to increase the strength of the patch. damage to the inner wall of the tire. The disadvantages of this tire patch are: [0003] 1. After using this rectangular patch on the damaged part of the tire, since the inner wall of the tire has a certain curvature, the rectangular patch needs to be bent in order to fit the inner wall of the tire, but the rectangular patch will produce a large reaction after bending. This is not conducive to the lamination of the patch and the inner wall of the tire. After being loaded into the inner tube and inflated, the inner tube will press the patch tightly to fit the inner wall of the tire. This patch is easy to crack during the use of the tire. [0004] 2. For ...

AI Technical Summary

Problems solved by technology

[0003] 1. After using this rectangular patch on the damaged part of the tire, since the inner wall of the tire has a certain curvature, the rectangular patch needs to be bent in order to fit the inner wall of the tire, but the rectangular patch will produce a large reaction after bending. This is not conducive to the bonding of the patch to the inner wall of the tire. After the inner tube is installed and inflated, the inner tube will press the patch tightly to the inner wall of the tire. This kind of patch is easy to crack during the use of the tire.

[0004] 2. For the patch embedded with nylon thread, its strength is poor, and the tire repair is easy to be damaged twice

In order to enhance the strength of the patch, a patch embedded with thin steel wires has appeared. The thin steel wires are arranged vertically or horizontally, and in a mesh arrangement, which are often only partially arranged with steel wires. This kind of patch will cause steel wires to break after the patch is broken during use. Fracture, and then cause damage to the inner wall of the tire and the inner tube, greatly reducing the service life of the tire

[0005] 3. The existing patch is bonded and fixed by adhesive layer or glue, the bonding effect is not good, and it cannot be well bonded and fused with the inner wall of the tire

[0006] 4. Existing patches are generally made of new rubber and steel wire, which is costly and wastes resources
