Description

Novel tire safety upgrading material and manufacturing method thereof
Technical Field
The invention relates to a new material, in particular to a new puncture-resistant, air leakage-proof, explosion-proof and bulletproof tire safety upgrading material and a manufacturing method thereof.
Background
With the rapid development of Chinese socialist market economy, the development of the Chinese automobile industry is also a day-to-day change, and whether in cities or rural areas, automobiles become a popular consumer product for common people, but the driving safety and the life safety of passengers are more and more generally concerned. Countless people are killed each year due to traffic accidents, and the discrete family relatives and the great economic loss are caused. At present, the automobile has three safety guarantees: safety belt, air bag, ABS anti-lock braking system, the puncture-resistant, leak protection, explosion-proof, shellproof safety tire is another safety guarantee system of car again so. The tire is the foot of the automobile, and the safety of the tire can ensure the driving safety. The vacuum tire without the inner tube of the latest generation commonly used in the market at present has the advantages of good heat dissipation, good comfort, low noise, good sealing performance and the like, but after being punctured by sharp objects such as nails and the like, the air pressure in the tire can be slowly leaked outwards, if the tire is punctured under the condition of high-speed running, more than 99 percent of conditions are always destroyed by a tire burst vehicle, and the life of people is greatly damaged.
To date, there are many methods for repairing tires to prevent the tires from being punctured, deflated and burst, and these methods are mainly classified into the following types:
1. the first generation products were the first type of repair materials represented by liquid adhesives that were developed in the eighties and ninety years of the last century. After the tire is punctured by sharp foreign matters, the liquid colloid is oxidized when contacting with air at a puncture opening and is adhered to the punctured wound to achieve the effect of leakage repair.
2. The second generation product is a semi-solid hot melt adhesive prepared by blending a styrene thermoplastic elastomer polymer, tackifying rosin resin, a softening agent and an anti-aging agent at the beginning of the century, the semi-solid hot melt adhesive is adhered to the inner wall of a tire, and when the tire is punctured by a sharp foreign body, the adhesive can be automatically repaired to achieve the effect of preventing air leakage.
The two generations of products solve the problem of air leakage prevention of tires to different degrees, but have a plurality of major defects. As for the first generation of liquid adhesive, the aging resistance time is short, the air leakage prevention duration is short, the tire air pressure cannot be guaranteed, and the hidden danger of tire burst exists at any time. For the second generation semi-solid hot melt adhesive product, when the tire runs at a high temperature of more than 70 ℃, the adhesive can flow and can not be firmly adhered to the inner wall of the tire, so that the effect of preventing air leakage when sharp foreign matters puncture the tire can not be achieved, and the dynamic balance of the tire is broken; poor low temperature resistance: under the condition of extremely cold at low temperature, the colloid is frozen into blocks, the inherent performance of the product is lost, and the functions of preventing pricking and preventing air leakage cannot be achieved. This is a seemingly simple product, but in practice is a very complex and technically demanding product. The two generations of products can not really achieve the effects of high temperature resistance of 120 ℃ and low temperature resistance of-40 ℃, the protective layer can not be uniformly adhered to the inner wall of the tire, the dynamic balance of the tire can not be kept, and the products are easy to fall off and off after sharp foreign matters puncture the tire, so that the effects of puncture resistance, air leakage prevention and explosion prevention can not be achieved.
Therefore, the research and development of a new material for safely upgrading a puncture-resistant, air leakage-proof, explosion-proof and bulletproof tire and a manufacturing method thereof become problems to be solved by technical personnel in the field.

(4) and cooling the sprayed tire safety upgrading new material, sending cold air into the inner wall of the tire body, cooling, solidifying and shaping the sprayed sealing new material, and stopping cooling after the shaping is completed when the temperature is cooled to 40 ℃.
