Problems solved by technology

The disadvantages of this method are: (1) The vulcanization temperature is too high, which leads to premature aging of the tire and the vulcanization back to the original phenomenon; (2) The inner liner of the tire is damaged, the repair quality is not good, and the service time is short, especially not for use The repair of car radial tires can easily lead to bubbles in the inner liner and air leakage; (3) High temperature causes rubber and cord aging, and the repaired tires cannot be remanufactured, resulting in waste of resources; (4) Uneven vulcanization pressure , leading to partial inaccurate bonding of the patch, affecting the repair quality; (5) Excessive energy consumption

Embodiment 1

[0016] 195 / 60R14 86H passenger car radial tires are the first batch of remanufactured tires developed by our company. They belong to high-speed tires. The above process has been repaired.

[0017] (1) Mark cleaning: check the radial tire to be repaired, mark the hole, clean the hole, and then suck up the dust; after inspection, it is confirmed that the hole of the 195 / 60R14 86H tire is located in the center of the crown , the diameter of the hole is less than 3mm, which belongs to the repairable tire. Mark the hole with white chalk.

[0018] (2) Grinding: Grinding the damaged parts of the radial tires obtained in step (1), the grinding area is equal to the area of ​​the template used for vulcanization, and all of them are rounded to ensure the aesthetics of the tire after repair and the tire The airtight performance is not affected; the carcass cord is not visible at the grinding depth;

[0019] The electric grinder is installed on a fixed bracket with a base, which can mov...

Abstract

The invention relates to a repairing process of a radial tyre of a passenger car, and particularly relates to a repairing process before remanufacturing of a radial tyre of a passenger car, belonging to the technical field of tyre repairing. The flow process provided by the invention comprises the steps of cleaning marks, grinding, carrying out secondary cleaning, fitting rubber materials, vulcanizing formation and carrying out postprocessing. According to the repairing process, the recycling rate of the radial tyre of the high-speed-level passenger car is improved greatly; the safety performance of a remanufactured tyre in the using process is ensured effectively; the energy consumption from the recycling of the tyre to the repairing process is lowered, so that the call of national energy conservation and emission reduction is responded actively; the repairing surface is decorated and treated during the repairing process so as to achieve the beautiful visual effect and promote the recognition of the remanufactured tyre by people, so that the repairing process is identical to the recycling concept of developed countries, and the consciousness of energy conservation and emission reduction realized by all people is promoted.

Description

technical field [0001] The invention relates to a repairing process for car radial tires, in particular to a repairing process for car radial tires before remanufacturing, and belongs to the technical field of tire repairing. Background technique [0002] At present, the thermal vulcanization technology for tire repair is mainly high-temperature thermal vulcanization, commonly known as fire repair. The disadvantages of this method are: (1) The vulcanization temperature is too high, which leads to premature aging of the tire and the vulcanization back to the original phenomenon; (2) The inner liner of the tire is damaged, the repair quality is not good, and the service time is short, especially not for use The repair of car radial tires can easily lead to bubbles in the inner liner and air leakage; (3) High temperature causes rubber and cord aging, and the repaired tires cannot be remanufactured, resulting in waste of resources; (4) Uneven vulcanization pressure , leading to...
