Problems solved by technology

For example, Chinese invention patents CN1935894A and CN101381503A disclose a kind of polymer material for manufacturing anti-puncture and leak-proof; ; Chinese utility model patent CN201346963Y, invention patent CN101497297A respectively disclose a kind of support for safe driving after a car wheel blows out. Patent Application No. 201110050718.8 discloses a solid bulletproof (explosion-proof) tire, which is combined with a car wheel hub to form a bulletproof (bulletproof) car wheel. There is no car tire blowout problem, but there is softness and poor ride comfort, which is not suitable for passenger cars. , cars and vehicles carrying people, only suitable for vehicles carrying goods
[0009] This shows that the above-mentioned existing anti-puncture and anti-leakage methods and devices for automobile tires obviously still have many inconveniences and defects in the anti-explosion of automobile tires, and need to be further improved.
In order to solve the above-mentioned problems, relevant manufacturers, research institutes and institutes have tried their best to find solutions, but no applicable methods and devices have been found for a long time.

Abstract

The invention relates to a process for achieving temperature resistance upgrade of a car wheel. The process comprises the following steps of removing the car wheel; disassembling the car wheel into a hub and a tire; cleaning the inner wall of the tire; spraying a polymer hot-melt self-closing and repair memory adhesive layer on the inner wall of the tire of the car wheel; assembling the car wheel; inflating the car wheel with inert gas; balancing the car wheel; installing the car wheel, wherein the polymer hot-melt self-closing and repair memory adhesive comprises the following components by weight percent: (1) 40-60% of thermoplastic elastomer; (2) 34-51% of tackifier; (3) 5-8% of softener; (4) 0.5-1.5% of anti-aging agent and / or antioxidant. By adopting the process, the car wheel can be upgraded to a security car wheel which can normally operate at minus 40 DEG C to 120 DEG C and is bullet-proof inside, explosion-proof and resistant to puncture.

Description

technical field [0001] The invention relates to a process method for upgrading the temperature resistance of automobile wheels, in particular to a method for safely upgrading the inner wall of automobile tires by spraying polymer hot-melt self-sealing sealant memory glue to achieve the purpose of high and low temperature resistance. Background technique [0002] A set of figures shows the seriousness of China's automobile traffic accidents. In 2006, there were more than 370,000 road automobile accidents in China, killing more than 90,000 people and injuring more than 370,000 people. According to statistics in 2007, there were 136,894 car accidents, 30,813 people were killed, and about 150,000 people were injured. It is down from the same period last year, but the absolute number is still very large. In particular, the number of automobiles in China is far lower than that of some advanced countries, but the rate of automobile traffic accidents and casualties is much higher t...
