Problems solved by technology

Spherical rubber particles can enter the cracks to seal the cracks when the tire cracks are large, but in actual operation, the self-sealing effect of spherical rubber particles is difficult to reach the level of self-sealing rubber, and the fluidity of spherical rubber particles is relatively large. Long-term use It is easy to cause rubber material falling off, flanging, displacement and rubber material accumulation

Embodiment 1

like Figure 1-2 As shown, a high-performance composite rubber strip for self-sealing safety tires includes a self-sealing material layer 1 and an elastic film 2 arranged on the upper side of the self-sealing material layer. The self-sealing material layer includes a self-sealing filling material 3 and a wrapping In the support sheet layer 4 near the elastic film side in the self-sealing filling material, the support sheet layer is composed of a plurality of bowl-shaped support sheets 5, and the concave surface of the support sheet faces the side away from the elastic film; The support sheets are connected, and the connection is a weak point that is easy to disconnect, for example, it can be made into a form similar to an easy tear line; the support sheet layer has a certain support for the entire rubber strip, so that the rubber strip is not easy to fall off. , flanging, displacement and rubber accumulation; the self-sealing rubber strip body is used to lay on the inner side o...

Embodiment 2

Similar to Embodiment 1, the difference lies in that the supporting pieces are connected with adjacent supporting pieces, and there is no gap between adjacent supporting pieces.

[0037] Correspondingly, a method for producing a high-performance composite rubber strip for self-sealing safety tires includes the following steps:

Lay the elastic film on a flat surface, apply glue, place the supporting sheet layer without gap between the supporting sheets on the elastic film, make the supporting sheet layer and the elastic film bond, pour in the self-sealing slurry, self-leveling or mechanical processing. After flattening, cool the release film for use; when placing the support sheet, the concave side of the support sheet is facing up.

Abstract

The high-performance composite rubber strip comprises a self-sealing material layer and an elastic film arranged on the upper side of the self-sealing material layer, the self-sealing material layer comprises a self-sealing filling material and a supporting piece layer wrapped on the side, close to the elastic film, in the self-sealing filling material, and the supporting piece layer is composed of a plurality of bowl-shaped supporting pieces; the concave face of the supporting piece faces the side away from the elastic film. Each supporting piece is connected with the adjacent supporting piece, and the joint is a weak point easy to break; the self-sealing rubber strip body is used for being laid on the inner side of a tire to achieve the tire self-sealing effect. When the sharp part of the supporting piece pierces, the sharp part enters or slides into the concave part of the supporting piece, the supporting piece bears the sharp part, the sharp part jacks up the supporting piece, the peripheral self-sealing filling material is promoted to draw close to the sharp part to form sealing, the adhesive tape does not need to be sprayed, the interior of the tire is treated, and then the adhesive tape is attached, so that the production cost is low, and in addition, the safety of the tire is improved. And the rubber strip can be replaced, so that the service life of the self-sealing tire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of self-sealing materials, and in particular relates to a high-performance composite rubber strip for self-sealing safety tires and a production method thereof. Background technique [0002] The phenomenon of puncture, side shift and uncontrolled tires caused by punctured tires is one of the culprits of many car accidents, and it is also the enemy of tire life (many brands of tires are not recommended to continue after 1-2 tire repairs. use). [0003] With the development of science and technology, safety tires that can still not leak after being punctured came into being, and they are used more and more. One of the reasons for the high price of flat tires. Generally speaking, the protective layer of rubber used for tire puncture and leakage prevention is basically spraying equipment to evenly spray the rubber to the inner wall of the tire. Before spraying, the inner wall of the tire is cleaned and polishe...
