Low-temperature-resistant and high-speed-resistant tire self-repairing liquid as well as preparation method and application thereof

Abstract

The invention discloses a low-temperature-resistant and high-speed-resistant tire self-repairing liquid. The liquid comprises the following components in percentage by weight: 45-55% of natural rubber latex, 1.5-2.5% of a surfactant, 28-32% of an anti-freezing agent, 17.5% of a tackifier and 0.5% of an anti-aging agent. The invention further discloses a corresponding preparation method. The invention further discloses application of the self-service repair liquid, and the self-service repair liquid can adapt to professional car repair, autonomous emergency car repair and tire puncture prevention. The natural latex and the reinforced polymer used in the self-repairing liquid have the same property as the tire, always exist in the tire in a liquid form, cannot be solidified, can be used for a long time at the temperature of minus 40 DEG C to 80 DEG C, are non-corrosive, non-toxic, non-combustible and non-explosive to the tire, have the quality guarantee period as long as 5 years, have no pollution to the environment and are very convenient to use.

Description

technical field [0001] The invention relates to the technical field of tire repair, in particular to a low-temperature and high-speed-resistant tire self-repair liquid and its preparation method and application. Background technique [0002] Car tires often cannot be rescued in time because of the blowout caused by puncture, especially in remote areas because of the traffic accidents caused by blowout. Therefore, out of the consideration of vehicle driving safety, the anti-puncture tire self-healing agent was developed in the early years. [0003] Traditional tire repair agents can be divided into pure solid filling, liquid phase repair, and a layer of anti-puncture fiber embedded in them. The main problems include: resonance obviously affects ride comfort, vehicle body is unbalanced, repair agent has short service life and cannot be used normally It works under extreme (high temperature, low temperature) conditions, and the weight gain of the vehicle body obviously increas...

AI Technical Summary

Problems solved by technology

[0003] Traditional tire repair agents can be divided into pure solid filling, liquid phase repair, and a layer of anti-puncture fiber embedded in them. The main problems include: resonance obviously affects ride comfort, vehicle body is unbalanced, repair agent has short service life and cannot be used normally Effective under extreme (high temperature, low temperature) conditions, the weight of the body will increase energy consumption significantly, and the cost will be high

[0005] The following problems still exist in the existing latex tire self-refilling liquid: 1) the homogeneity of the latex is poor, and the valve core needs to be pulled out to pressurize and inject into the tire, which is not conducive to self-operation; 2) the chemical stability of the latex is poor, Especially when the tire rotates at high speed, the latex deteriorates faster, so it is often only used as an emergency self-repair fluid. When the tire is punctured, inject the self-repair fluid and drive for a while, and continue to repair the tire
