Abstract

The invention discloses a high polymer anti-leakage dense patching material, which comprises by weight hot plastic elastomer 40-60%, thickener 40-60%, softening agent 08%, anti-aging agent 0-2%, catalyst 0-1%, and filling agent 0-15%. The invention also discloses an anti-leakage tyre containing above mentioned high polymer anti-leakage dense patching material, which can efficiently prevent tyre from air leakage and tyre bursting due to pricking of the tyre, guarantee safety in running of vehicles and prolong the service life of tyres. And the use effect of the tyres will not be affected due to the machining (for example dynamic balancing, operation, braking, comfortableness and load bearing capacity, etc.).

Description

technical field

[0001] The invention relates to a polymer leak-proof close-fitting material and a leak-proof tire containing the material. Background technique

[0002] To solve the problem of tire puncture and air leakage at an early date, the whole world has already invested a lot of manpower, material resources and financial resources. For example, after a tire of a well-known brand is punctured, it can only be supported by the automatic skeleton, and can continue to drive for 80 to 200 kilometers, but the rim and tire are all scrapped, and the tire and rim still need to be replaced in the end, and the price is as high as thousands of dollars. Prior to this, tire sealants were popular for a while, but due to the fatal flaws brought about by the inherent physical and chemical properties of liquid materials, high-speed driving affects the dynamic balance of vehicles, which cannot guarantee safe driving, short effective service life and tire inner cavity and The strong corr...
