Problems solved by technology

The disadvantage is that the hole in the carcass is not blocked, and the air and water cannot be blocked during the driving process in the future. It may cause steel wire corrosion and cause tire deformation, and air leakage may occur again at the repaired place.
Therefore, like the rubber strip plugging method, it is only suitable for small vehicles, and cannot be used for large trucks with heavy loads.
[0006] In the prior art, all-steel wire radial tires are generally used for tires of large trucks with large load capacity, but the existing cold repair technology is not suitable for complementing steel wire radial tires due to material and technical problems, so tire repair methods are all heat supplement

Embodiment 1

[0023] At room temperature, mix 1Kg of natural rubber with carbon black and 3Kg of gasoline, add 0.3Kg of lexinone and 0.15Kg of epoxy resin after 24 hours to form a special rubber for cold patching of steel radial tires.

Embodiment 2

[0025] At room temperature, mix 1Kg of natural rubber with carbon black and 4Kg of gasoline, add 0.55Kg of sodium lexiconate and 0.3Kg of epoxy resin after 24 hours to form a special rubber for cold patching of steel radial tires.

Embodiment 3

[0027] Mix 1Kg of natural rubber with carbon black and 3.7Kg of gasoline at room temperature, add 0.47Kg of sodium lexiconate and 0.25Kg of epoxy resin after 24 hours to form a special rubber for cold patching of all-steel radial tires.

[0028] Utilize the cold repair film and special glue of the present invention to repair the tire, apply the special glue on the adhesive surface 1a, the glue reacts with the adhesive surface 1a, paste the film coated with the special glue on the adhesive surface 1a on the tire wound surface, and the process is completed Tire repair work.

Abstract

The present invention discloses vulcanized patch for cold repairing all steel radial tire and special glue for repairing tire with the patch. The vulcanized patch is one vulcanized and formed rubber body with adhering surface and embedded steel wire cord. When it is used in cold repairing tire, there is no need of secondary vulcanization of the local tire, and the repaired tire has greatly prolonged service life and unaffected dynamic balance and may be retreaded for the second time. The repaired tire is further vulcanized by means of the friction heat between the tire and ground and the patch has firm combination to the tire and excellent sealing performance. The cold repair has short repair period, low cost and high strength.

Description

technical field [0001] The invention relates to a tire repair film and viscose, in particular to a cold repair film for all-steel radial tires and a special rubber for tire repair using the film. Background technique [0002] The tire repair methods for damaged tires can be roughly divided into three types according to the degree of tire damage: cold repair, hot repair and rubber strip method. [0003] At present, hot patching is the most thorough tire patching measure. Hot repair requires the tire to be removed from the wheel hub, and then a special raw film is attached to the wound. Then bake the wound with a baking machine until the raw film is completely bonded to the tire. The advantage of hot patching is that it is more durable, and there is basically no need to worry about repeated air leakage at the wound. The local vulcanization of hot glue tire patching can make the rubber fully bonded, and the tire patching effect is better. The disadvantage is that the tire re...
