A method for improving a cement spraying efficiency for a self-repairing tire includes: inputting tire parameters into a control system, including rim diameter, section width, aspect ratio, cement thickness and cement density; calculating a cement spraying amount for a tire; calculating a crown cement thickness separately; starting a spraying device, and evenly spraying a cement in a cement storage tank on a tire surface; and finally drying, that is, heating to speed up solidification of the cement, thereby completing self-repair. The control system automatically calculates the cement spraying amount required for repair based on the tire parameters such as section width, aspect ratio and rim diameter, and realizes mass production of self-repairing tires according to the characteristics of the tires. The method is applicable to all tires of different specifications, and can realize a one-time spraying operation, thereby improving the spraying efficiency for self-repairing tires.

This disclosure relates to an approach for monitoring a tire for a puncture based on a change in a voltage established based on a resistance of a material disposed within the tire. In one example, the material is a conductive material layer. In another example, the material is a resistive strip. The systems and methods described herein can monitor for a change in an established voltage over time that is a function of parameters including the resistance of the conductive material layer or the resistive strip, and an applied voltage, to provide an indication of the change in the resistance in the material. The change in resistance of the material can be indicative of the puncture within the tire. The systems and methods described herein can alert a vehicle operator of the puncture within the tire.

A method for preparing a modified rubber introduces a reactive group into a high-performance short fiber by irritating the short fiber by ultraviolet light, and modifies the short fiber by a coupling agent to increase the compatibility of the short fiber with a rubber matrix, and finally, utilizes the charge repulsion of sodium lauryl sulfate to effectively avoid the agglomeration of the short fibers in the rubber matrix, which is benefit for obtaining the modified rubber. The present disclosure further provides a modified rubber prepared by the method and a bulletproof and puncture resistant tire prepared by the modified rubber, wherein a buffer layer is made by the modified rubber, and at least one of a tread, a belt ply and an inner liner is made by the modified rubber, and a cord ply is woven by twisted high-performance long fibers.

A puncture resistant mute explosion-proof cushion for a tyre and a wheel thereof are provided. The explosion-proof cushion is annular, received in the tyre and made of composite nano vinyl acetate copolymer. The explosion-proof cushion includes an inner ring and an outer ring wrapped on the inner ring; when the explosion-proof cushion is installed in the tyre, the outer ring is attached to a top surface and a side surface of an inner wall of the tyre, and a height from the inner ring to the outer ring along a radial direction of the explosion-proof cushion is less than a height of the side surface of the inner wall of the tyre. The explosion-proof cushion of the present disclosure can improve comfort during ordinary driving of the tyre, and simultaneously can protect an integral structure of the wheel when the tyre runs under a condition of a tyre burst.

The method of this invention provides a simple and inexpensive method for manufacturing self-sealing pneumatic rubber tires of the tubeless type having a higher degree of uniformity than can be made utilizing conventional manufacturing procedures that are currently being practiced. In the practice of this invention a low viscosity sealant formulation, which would ordinarily be difficult to handle and build into an uncured tire, is encapsulated in a stiff rubber formulation. This makes it relatively easy to build the sealant layer into the tire since the low viscosity sealant formulation is contained with the more rigid solid material. The low viscosity sealant material requires little and preferably no depolymerization to act effectively as a sealant. Accordingly, it does not need to be depolymerized with a peroxide which causes off-gassing and the resultant tire uniformity and balance issues normally associated with polymer break down.
