Description
Technical Field
The invention relates to the technical field of tire glue, in particular to a puncture-proof, explosion-proof and leak-proof auxiliary tire glue and a preparation method thereof.
Background
By 9 months in 2020, the number of motor vehicles in the country reaches 3.65 hundred million, wherein 2.75 million automobiles are kept, and the tire is influenced by factors such as road surface conditions, sharp object pricks, the quality of the tire and the like during the running process of the automobiles, so that the tire leakage is a phenomenon which is often encountered during the daily running process of the automobiles, and the leaked tire can be normally used after being properly treated.
Among the numerous tire repair methods in the industry, the normal-temperature vulcanization repair method is favored by repair personnel and drivers due to the characteristics of simple operation, low price, small damage to the tire surface and the like, and has good market prospect.
The normal temperature vulcanizing tyre repairing glue used in the normal temperature vulcanizing repairing method is generally composed of tyre repairing glue hydrosolvent, natural glue and ultra-high speed accelerator.
In the actual normal-temperature vulcanization tire repair glue, a proper vulcanization accelerator is required to be selected, so that sulfur in the tire repair glue film is subjected to vulcanization with the accelerator in a short time, the tire repair glue film and the repaired surface of the tire are subjected to vulcanization crosslinking, and the purpose of repairing the leakage position of the tire is finally achieved; the selection of the tire cement hydrosolvent should select the solvent with high volatilization speed, good dissolving property and flame retardance as much as possible;
because the oxidation reaction of the hydrosolvent of the tire repairing glue during the storage process is determined by the characteristics of the hydrosolvent of the selected tire repairing glue, the accelerator in the normal-temperature vulcanization tire repairing glue is usually a dithiocarbamate ultra-overspeed accelerator, and the crosslinking reaction of the glue in the tire repairing glue is promoted by products such as hydrogen chloride generated by the decomposition of the solvent during the glue storage process, the viscosity of the glue is increased quickly, and finally the glue is caked and loses efficacy and cannot be normally used. The storage life of commercial normal-temperature vulcanization tire repair glue is required to be 1-2 years under normal conditions, so that a corresponding stabilizer needs to be added into the glue to ensure the stability of a used tire repair glue solvent, and the glue can meet the normal storage requirement of a product.
However, although the conventional stabilizer partially used for the tire repair cement aqueous solution can improve the storage stability of the room-temperature vulcanized tire repair cement, the adhesive force of the tire repair cement is reduced, so that the storage stability of the conventional tire repair cement cannot meet the market demand.
