Description
Technical Field
The utility model relates to an automobile tire technical field specifically is a glued structure of multilayer self-repairing of self-repairing tire.
Background
When the tubeless tire is used, the tubeless tire cannot keep air when being punctured, loses the support and bearing functions of the vehicle and is instantaneously damaged by rolling, which is always common.
The most common practice is to spray a self-repairing adhesive or stick a layer of self-repairing adhesive after the surface of an inner airtight layer of a finished tire is treated, so that a punctured hole is rapidly blocked or the surface of a punctured object is coated by the cohesion of a high polymer at the moment of puncturing the tire to form sealing, thereby ensuring that the tire maintains the internal pressure and the supporting function.
The self-repairing adhesive is soft at normal temperature and has strong adhesion, so that self adhesion is easily generated due to tire deformation during tire mounting or use, partial falling and caking are seriously caused, long-term inner surface uniformity cannot be ensured, and the uniformity of the tire and the normal exertion of the self-repairing function are influenced, which are places suffering from human problems in market application.
Disclosure of Invention
The utility model aims at overcoming above-mentioned weak point, provide a multilayer self repair glued structure of self repair tire, it has solved the problem of software high polymer delaminating/conglomeration, has also guaranteed the homogeneity in the tire use, accords with the requirement of safe carefree of long-term use.
The technical scheme of the utility model is a multilayer self-repairing glue structure of a self-repairing tyre, which comprises a steel wire ring, a tyre body cord fabric, an airtight glue layer and tread glue; the inner part of the carcass ply is supported by a steel wire ring, and the inner side of the carcass ply is provided with an airtight glue layer; the tread rubber is coated on the outer side of the carcass ply; also comprises a self-repairing glue layer and an outer coating glue layer; the inner side of the airtight glue layer is provided with a self-repairing glue layer, and the inner side of the self-repairing glue layer is provided with an outer coating glue layer;
the self-repairing glue layer is arranged between the airtight glue layer and the outer covering glue layer;
the self-repairing glue layer is at least two layers of self-repairing glue, and a separation layer is arranged between the layers of the self-repairing glue.
Furthermore, the self-repairing rubber layer of the self-repairing tire is a soft high polymer rubber sheet.
Further, the self-repairing rubber layer and the self-repairing tire are formed in one step.
Further, the tire structure with the multilayer self-repair cement structure is applied to all vacuum tires.
Further, the vacuum tire specifically comprises an electric bicycle tire, a cart tire, a motorcycle tire MC, a car tire PCR or a truck tire TBR.
The utility model has the advantages that: the utility model discloses can ensure that the tire keeps from repairing the function in service life, the software is from repairing gluey delaminating, not conglomeration, does not influence the homogeneity of tire.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1. a bead ring; 2. a carcass ply; 3. an airtight glue layer; 4. a tread rubber; 5. self-repairing the glue layer; 6. coating a glue layer outside; 7. a separation layer.
Detailed Description
The soft polymer films described in the following examples were obtained from a polymer nano memory synthetic material, commercially available as MPN rubber, manufactured by Wuxi Angichz science and technology Limited.
As shown in fig. 1, a multilayer self-repairing glue structure of a self-repairing tire comprises a steel wire ring 1, a carcass ply 2, an airtight glue layer 3 and a tread glue 4; the inside of the carcass ply 2 is supported by a steel wire ring 1, and the inner side of the carcass ply 2 is provided with an airtight rubber layer 3; the tread rubber 4 is coated on the outer side of the carcass ply 2; also comprises a self-repairing glue layer 5 and an outer coating glue layer 6; the inner side of the airtight glue layer 3 is provided with a self-repairing glue layer 5, and the inner side of the self-repairing glue layer 5 is provided with an outer coating glue layer 6;
the self-repairing glue layer 5 is arranged between the airtight glue layer 3 and the outer covering glue layer 6;
the self-repairing glue layer 5 is at least two layers of self-repairing glue, and a separation layer 7 is arranged between the layers of the self-repairing glue.
The self-repairing rubber layer 5 of the self-repairing tire is specifically a soft high polymer rubber sheet.
The self-repairing glue layer 5 and the self-repairing tire are formed in one step.
Tire structures with multilayer self-healing cement structures are used in all vacuum tires. The vacuum tire specifically comprises an electric bicycle tire, a rickshaw tire, a motorcycle tire MC, a car tire PCR or a truck tire TBR.
The utility model discloses but paste the one deck vulcanization on software high polymer film surface and cover the glue film outward, get up software high polymer film protection, have the separate layer between the layer, can ensure the distribution homogeneity of gluing and the validity of self-repairing function.
The utility model discloses the concrete preparation method does: high polymer is taken out (coated with film), compounded with rubber sheet, molded and vulcanized, and finally the finished product is obtained.
The utility model discloses just make up the software high polymer film into when child embryo shaping to adopt and cover the glue film 6 outward and carry out the cladding to it, vulcanize the back finished product and have had the self-repair glue film, when guaranteeing the self-repair function, overcome the possibility of delaminating/conglomeration, do not have the problem that influences the homogeneity. The rubber material adopted by the outer rubber coating layer is the rubber material of the inner surface of the tire.
Because the soft high polymer is a high polymer with high cohesion and extremely strong self/mutual adhesion, and has extremely high adhesion to metal, the key point is how to realize the green tire forming and fitting.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
