Background
When in use, the tubeless tire is easy to be punctured by various sharp objects, cannot keep air, loses the support and bearing functions of the vehicle and is instantaneously damaged, and 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.

According to the technical scheme, the puncture-proof tire structure comprises a steel wire ring, a tire body cord fabric, an aramid fiber buffer layer, an airtight rubber layer and tread rubber; the interior of the carcass ply is supported by a steel wire ring, an aramid fiber buffer layer is arranged outside the carcass ply, and an airtight glue layer is arranged on the inner side of the carcass ply; the tread rubber is coated on the outer sides of the aramid fiber buffer layer and the carcass ply;
the method is characterized in that: 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 a single-layer or multi-layer self-repairing glue structure, and an aramid fiber buffer layer is arranged on the inner side of the tread glue layer.
Furthermore, when the self-repairing glue layer is multi-layer, a separation layer is arranged between layers of the multi-layer self-repairing glue.
Furthermore, the self-repairing glue layer of the puncture-proof tyre is a soft high polymer glue sheet.
Further, the self-repairing glue layer and the puncture-proof tire are formed in one step.
Furthermore, the aramid fiber buffer layer has a two-layer structure which is mutually crossed.
Further, the puncture preventing tire 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 invention pastes a layer of outer covering glue layer which can be vulcanized on the surface of the soft high polymer film to protect the soft high polymer film, and a separation layer is arranged between the multiple layers of self-repairing glue layers, thus ensuring the distribution uniformity of glue and the effectiveness of self-repairing function.
The invention adds 2 layers of aramid fiber buffer layers to the tire, and the high specific strength of the aramid fiber endows the tire with puncture resistance.
The preparation method comprises the following steps: gluing/cutting aramid fiber, producing high polymer film, compounding with rubber sheet, forming blank, and vulcanizing to obtain the final product.
The invention has the beneficial effects that: the invention can ensure that the tire keeps high puncture resistance and self-repairing function in the service life, and the soft self-repairing glue does not delaminate and agglomerate and does not influence the uniformity of the tire.

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, the puncture-proof tire structure comprises a steel wire ring 1, a carcass ply 2, an aramid fiber buffer layer 8, an airtight rubber layer 3 and a tread rubber 4; the inside of the carcass ply 2 is supported by a steel wire ring 1, an aramid fiber buffer layer 8 is arranged outside the carcass ply 2, and an airtight glue layer 3 is arranged on the inner side of the carcass ply 2; the tread rubber 4 is coated on the outer sides of the aramid fiber buffer layer 8 and the carcass ply 2;
the method is characterized in that: 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 a single-layer or multi-layer self-repairing glue, and a separation layer 7 is arranged between layers of the multi-layer self-repairing glue layer;
the inner side of the tread rubber layer 4 is provided with an aramid fiber buffer layer 8.
Furthermore, the self-repairing glue layer 5 of the puncture-proof tyre is specifically a soft high polymer film.
Further, the self-repairing glue layer 5 and the puncture-proof tire are formed in one step.
Further, the aramid fiber buffer layer 8 has a two-layer structure which is crossed with each other. Provides the function of preventing the puncture of the tire.
The puncture-proof tire structure is applied to all tubeless tires, and the tubeless tire specifically comprises an electric bicycle tire, a rickshaw tire, a motorcycle tire MC, a car tire PCR or a truck tire TBR.
According to the invention, the aramid fiber buffer layer and the soft high polymer rubber sheet are combined when the tire blank is molded, the soft high polymer rubber sheet is coated by the outer coating rubber layer, and the vulcanized finished product has the aramid fiber buffer layer and the self-repairing rubber layer, so that the puncture resistance of the tire is improved, and the self-repairing rubber sheet also has a self-repairing function, thereby overcoming the possibility that the tire is not puncture resistant and puncture leakage, ensuring that the self-repairing rubber is not delaminated/agglomerated, and having no problem of influencing uniformity. 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.
