Problems solved by technology

However, when natural rubber is used, it needs to be soaked in toluene to make it expand and soften. After absorbing the toluene released by the rubber particles, the tire will become brittle and easy to crack. Moreover, toluene is a dangerous product and is easy to explode.
[0004] At present, most of the tire sealants cannot meet the extreme weather in Heilongjiang, Russia, Hokkaido, Japan and other regions. The extreme temperature in these areas can reach below minus 30°C. How to ensure the low temperature tire repair effect while controlling the cost in the early stage is a must Problem to be solved by the present invention

The tire repairing liquid disclosed by the invention can meet the requirement for ultra-low-temperature working at negative 40 DEG C, is particularly suitable for being used in Heilongjiang Province of China, Russia, Hokkaido of Japan, and other regions, causes no any harm to a tire, and has no any impact on the normal use of TPMS.

Description

technical field [0001] The invention relates to the technical field of polymer synthesis, in particular to a low-temperature-resistant vacuum tire sealant and a preparation method thereof. Background technique [0002] Most of the tires used at this stage are inflated tubeless tires. If they are punctured by nails or hard objects on the road, they will cause acute deflation, and the lighter ones will break down. . Traditional puncture sealants have to go through a series of procedures such as unloading, stripping, and repairing tires. The procedures are complicated, laborious and time-consuming, especially when driving in the field and at high speed, they do not have the conditions for repairing tires. After the tire is punctured, it is impossible to continue driving. . [0003] In order to solve the above problems, some people have invented tire repair glue, most of which adopt polyvinyl acetate emulsion or polyvinyl alcohol solution, together with starch, cellulose and i...
